Answer
Monitor your electricity use by buying a Kill-A-Watt or other such monitor.

http://the-gadgeteer.com/review/kill_a_watt_electric_usage_monitor_review

'An average household uses about 4300kWh of electricity each year. This results in emissions of over 2 tonnes of CO2 per household, or ¾ tonne per person - just for domestic electricity supply. In comparison, total CO2 emissions per person in the UK are around 10 tonnes, and emissions per person in India are about 1 tonne. Luckily, it is possible to cut domestic electricity use in half with simple energy efficiency measures.
'This table shows how electricity use is divided up in an average house (excluding electric heating):

Lighting 19%
Cold Appliances 18%
Wet Appliancs 15%
Cooking 15%
Consumer Electronics 19%
ICT (computers, etc) 9%
Other 5%'

EASY WAYS to save energy

â Don't use standby on tv or computer.
â Switch off when not in use.
â Use energy efficient lightbulbs.
â Lower you thermostat.
â Install timers.
â Heat only what is needed.
â Turn down the water heater.
â Insulate your property.
â Turn air conditioning and heating down
â Sign up to a green energy supplier.
â Dress appropriately. When itâs cold put on a jumper rather than turn up the heating, when itâs warm take it off again rather than use the air con.
â Wash full loads.
â Wash at lower temperatures.
â Dry washing outside.
â Avoid dishwashers.
â Reduce draughts.

Use rechargeable batteries..
â Donât leave (re)chargers on for longer than is needed
â Only boil the water you need.
â Buy local produce.
â Reduce reuse and recycle - in that order
â Work from home. If possible work from home, it saves time and fuel travelling.
â Eat less meat and dairy products. Modern farming methods produce large quantities of greenhouse gases.
â Shower instead of bath.
â Conserve Water The less water you use the less energy is needed to pump it to your home or office and to deal with the waste at a sewerage treatment works.

â Drive a fuel efficient vehicle, if you have more than one vehicle use the most economical one more often.
â Walk or cycle to work or when taking the kids to schools, if you have to drive consider car sharing.
â Use public transport where possible
â Take a coach or train instead of using domestic flights.
â When replacing your vehicle look at diesel and liquid petroleum gas models.
â Combine multiple journeys into one and do your weekly shopping in a single trip.
â Stagger journeys where possible to avoid rush hour traffic and hold ups.
â Avoid harsh braking, accelerate gently, drive at a steady speed.
â Keep tyres properly inflated.
â Remove bike and ski and roof racks when not in use.
â Carrying unnecessary weight wastes fuel, declutter your vehicle.
â Use the correct gear, use cruise control if your vehicle has it.
â Keep your vehicle regularly serviced.
â Turn the engine off when stopped or waiting.

How to protect the environment?




swmiyah


what are some examples of sustainable practices and stewardship that can protect the environment?


Answer
In Your Home â Conserve Energy
Clean or replace air filters on your air conditioning unit at least once a month.
If you have central air conditioning, do not close vents in unused rooms.
Lower the thermostat on your water heater to 120.
Wrap your water heater in an insulated blanket.
Turn down or shut off your water heater when you will be away for extended periods.
Turn off unneeded lights even when leaving a room for a short time.
Set your refrigerator temperature at 36 to 38 and your freezer at 0 to 5 .
When using an oven, minimize door opening while it is in use; it reduces oven temperature by 25 to 30 every time you open the door.
Clean the lint filter in your dryer after every load so that it uses less energy.
Unplug seldom used appliances.
Use a microwave when- ever you can instead of a conventional oven or stove.
Wash clothes with warm or cold water instead of hot.
Reverse your indoor ceiling fans for summer and winter operations as recommended.
Turn off lights, computers and other appliances when not in use.
Purchase appliances and office equipment with the Energy Star Label; old refrigerators, for example, use up to 50 more electricity than newer models.
Only use electric appliances when you need them.
Use compact fluorescent light bulbs to save money and energy.
Keep your thermostat at 68 in winter and 78 in summer.
Keep your thermostat higher in summer and lower in winter when you are away
Insulate your home as best as you can.
Install weather stripping around all doors and windows.
Shut off electrical equipment in the evening when you leave work.
Plant trees to shade your home.
Shade outside air conditioning units by trees or other means.
Replace old windows with energy efficient ones.
Use cold water instead of warm or hot water when possible.
Connect your outdoor lights to a timer.
Buy green electricity - electricity produced by low - or even zero-pollution facilities (NC Green power for North Carolina - www.ncgreenpower.org). In your home-reduce toxicity.

In Your Home â Reduce Toxicity
Eliminate mercury from your home by purchasing items without mercury, and dispose of items containing mercury at an appropriate drop-off facility when necessary (e.g. old thermometers).
Learn about alternatives to household cleaning items that do not use hazardous chemicals.
Buy the right amount of paint for the job.
Review labels of household cleaners you use. Consider alternatives like baking soda, scouring pads, water or a little more elbow grease.
When no good alternatives exist to a toxic item, find the least amount required for an effective, sanitary result.
If you have an older home, have paint in your home tested for lead. If you have lead-based paint, cover it with wall paper or other material instead of sanding it or burning it off.
Use traps instead of rat and mouse poisons and insect killers.
Have your home tested for radon.
Use cedar chips or aromatic herbs instead of mothballs.

Ways To Protect Our Air

Ask your employe

what is the advantage of having an electric motor on the hubs of electric bikes?

best hybrid electric bikes on style bikes available online in any recommendations for hybrid bikes

Q. aiming to modify my bike during the summer.


Answer
1. it looks better, neater
2. it is easily engineered to regenerative braking. On such a light vehicle it means less. If you are a more weightier rider it may mean more.
3. There is no shifting or gears on the motor.
4. efficiency due to fewer drive train losses.

An entirely different alternative is to make your ebike a series hybrid instead of a parallel hybrid and it is then also chain-less:

Using hybrid cars is one of the ways to prevent global warming?




riqzi


Its is a known fact that cars are one of the major contribution for green house gases. So recently the car manufactures come up with a new Eco friendly car, which is the hybrid cars. So my question is, if the global population adopt to hybrid car, can global warming be prevented?
http://preventglobalwarming.brighterplanet.org/



Answer
No. Hybrids are a step in the right direction, but while they emit less CO2, they still burn gasoline and they still emit carbon dioxide, which causes global warming.

If everyone drove a hybrid instead of a regular gas car, we would reduce worldwide greenhouse gas emissions, but not nearly enough to stop global warming.

Electric cars would reduce emissions even further, although they also are responsible for some CO2 emissions because some of our power comes from coal power plants, and burning coal emits CO2 as well. However, electric cars create less CO2 emissions than even hybrids.

In addition to switching to hybrids and electric cars, we need to take more steps. For example, becoming more energy efficient, swithing to renewable power plants and getting rid of coal power plants, biking and using public transportation, etc.

ronilo


we have a car and we suffer of this gas crisis. Im wondering why, nature does not get money from those oil miners, they get gases underground for free!!!!and why do they increase the prices of these FREE gases underground???

high demand??? what a heck, why the dont suck gas underground to make millions and millions and billions of gallons of gas. or get a underground gas-sucking device???

im mad of those high prices.

or, mother nature makes it high to reduce global warming??? oh men, go back to bicycle...

and i expect that the prices WONT get down when it higher.



Answer
we cant do anything but to reduce the usage. china and other countries use more gases and we pay for it. bikes? electric cars are better. if the gas prices become low, i think it will be in 2012, or something like that.... and i think that we already sucked the rest of the underground gas. go electric!!!!

Answer
Yes, you'll be fine. You can ride a super-ped if you like. The Piaggio MP3 variants.
The only 250cc 400cc or 500 cc bikes you can ride in the UK with only a normal car driving license, no bike license needed.
They are petrol/electric hybrid 3-wheel bikes with very good fuel economy, excellent road grip, tilting suspension on the two front wheels and a decent performance including a quoted 0 - 60mph in 5 seconds for the 500cc but some people have had reliability problems with them, and they are not cheap.

Johnson


I am thinking about getting a motorcycle instead of a car for college. The university I am going to has a very large, closed in campus which isnt quite walkable, so I wanted to get a bike to get around quickly and efficiently, as well as go to the store for groceries (ill just get saddle bags, not a big deal). It will also be used to drive around a large city (Seattle), and taken on the I-5 highway occassionally, but not often. I dont need or want my bike to be very fast, just enough for the highway.

The Kawasaki Ninja 250 is a solid contender for me, mostly because of its price and positive reviews. I definitely want either a sport or naked bike, preferably under $3-4k, so it fits the bill. It isnt very fast either, which is frankly a plus for me. Is the Ninja a good bike for my uses? ie: every day use, commute, convenience in daily life, city riding.

The biggest concern for me is cost. I know the bike itself it cheap enough, but how about the insurance? What would I expect to pay with the good grades discount, being 18-19 years old, college student? Also on a family plan most likely, so some discounts can be expected there.

Thanks alot, I hope someone has some answers for me :)

Dirt bike question?!?




Amanda


I was wondering if anyone experienced in dirt bikes could help me out.

I am looking to buy a dirt bike but im not sure what one I should get.
I mostly want the back for track riding and not for trail riding. I am a female 5'1 and 100 pounds. I do not want to get a beginners bike but would rather have one I can keep for years to come. I do have a small amount of experience in riding. I was looking more towards a Yamaha but any brand could work.
I want a fast back with a good amount of power. Any help would be much appreciated.
Oh and im 19 almost 20 if that makes any difference.
What about something like a YZ 250F or YZ 250?? Not sure whats better though 2-stroke or 4.



Answer
The seat height on the YZ 125s and 250s will be too much for you. They are almost 40 inches. You will never be able to touch the ground. The ideal situation is sit on the seat and at least be able to touch your toes to the ground on both sides.

Check out the 2013 TTR125 LE 34" seat height, front disc brake, 4 stroke and electric start. Probably would work good for you.

what is the Future for motorcycles that haven't changed in style for years and same style motors?

best electric bike of india image



stardancer


China makes a 3 wheel car that seats 4 and is a 4 door.India makes ans Selle's 3 wheel cars
that gets over 50 miles Gal.



Answer
Given that the internal combustion engine is so inefficient, even the most efficient lose more energy in radiation (heat) than they transfer to the back wheel, I think the next major step will be in electric motors with the advent of light(er)weight batteries. Of course these are not necessarily more environmentally friendly â creating the electricity creates greenhouse gases, even manufacturing the batteries is a dirty industry â but they have instant huge torque, have few moving parts, are reliable and simple, and can use forward movement and braking to claw back some charge. Would increasing the number of wheels or seats improve motorcycles? In many cases the compromise will enlarge the bike so much that it loses many of its advantages especially in towns.

what is stopping people from just replacing a gas engine with an electric engine?

Q. What is stopping people from just replacing a gas engine with an electric engine. I know a little bit about cars but not enough to know this answer. What makes an engine go from 8000 rpm or so down back to like 1 or 2 thousand rpm when you shift gears. Could you do the same thing with an electric engine?
Where would i be able to look at find motors with the type of power a car would call for?


Answer
If you want the equivalent of a golf cart, there are companies that will make the conversion for you. It will cost you thousands of dollars and you won't be able to go from L.A. to Anaheim on a charge.

The biggest barrier is batteries.

Gasoline has an energy density of about 46.19 Newton-Meters per kilogram (energy units per unit of weight).

A lead acid battery (the cheapest kind) comes in at 0.11 NM/Kg. That means it takes more than 400 times as much lead-acid battery to get as much energy as the same weight of gas.

The next generation of battery, the nickel-metal-hydride (NMh) they use in most hybrids, has a better energy density, but it's still only twice as dense as a lead acid, or 200 times more weight for the same energy as gasoline. On an energy per cubic centimeter basis, it's a lot better, but still takes 100 times as much space per unit of energy.

The newest batteries, used in laptops and the all-electric Tesla sports car, are lithium-ion. An experimental Japanese sedan, the Eliica, with eight wheel motors and lithium-ion batteries ran 230 mph a few years ago, but it cost a fortune, and we haven't heard from it since. These batteries have an energy density by weight three times that of an NMh, and 5 times by volume. So gasoline is only18 times as dense by volume. Still, imagine having to find room for 18 gas tanks in your car!

As to gears, you need gears for mechanical advantage (like a lever) to allow the engine to remain in its most efficient operating range at varying speeds.

Most gas engines do their best work between about 2,400 rpms and 5,000 rpms. A high performance engine's range will be higher, but they all need gears, or else they either couldn't get going from rest (geared too high) or would run out of breath before they reached freeway speed (geared too low).

If you ever rode a ten-speed bike, you'll know that you need low gears for going up hills and high gears to keep up with the pedals going down. Same with a car.

the Tesla now has only one gear. That's because an electric motor produces its maximum torque (the force to move the car) at zero rpms (from a dead stop). If you want one, they are taking deposits. They only cost around $100,000.

BTW, if you want to avoid sounding uninformed, technically the electric unit is called a "motor" while the internal combustion one is called an "engine." It's an engineering distinction.

Can the pedaling energy charge the battery of an electric bike?

best electric bikes on Electric Bikes 2011

Drowzzy


Can the mechanical energy of pedaling be stored as electrical energy to be utilized later to run the bicycle automatically? I'm not talking about pure electric bikes that need regular charging, and not even about those that you pedal for a while as the bike stands still and then run it on electric power. I mean can you ride a bike and store the mechanical energy simultaneously? Will it be efficient? If so, then are such e-bikes available in the market, and what are they called so that I may Google for them?

Here's the scenario: I need a bicycle for regular commute, may be even for covering long distances. It's not feasible for a layman to pedal continuously for more than 5 to 10 miles. So I'm looking for a bike that you pedal for sometime, and when you're exhausted, you simply flick a button to make it run on electrical power which has been converted and stored from the mechanical energy of pedaling the bike; and then pedal again and auto-ride again and so forth. Will something like that be technically efficient, since you're moving the bike while pedaling as well as storing your spare energy?

Hope I haven't confused you. Thanks :)



Answer
You will have to pedal extra hard to keep the bike going and to charge the battery. It could be done, but it would be easier and more efficient to pedal a regular (lighter) bike.

Maybe you could use a large solar panel to power the bike

Hope I haven't confused you. Thanks :)



Answer
Yes, it can!

Electric cycles are readily available. You normally charge them from a mains supply and then you can part-pedal / part-drive them on your commute. You can often adjust the amount of assistance to be supplied by the motor enabling you to go faster but less far or vice versa. If you want to pedal the bike and store 50% (say) of your energy for later you can do so but you will be doing double the work when pedalling, so your commute will be, so to say, twice as hard or half as fast and take twice as long. That doesn't seem to make much sense, especially since electric cycles are heavy and pedalling them (with no motor assistance) even without any of your energy going to storage, will be quite slow and tediously tough.

What an electric cycle does do is re-charge the batteries when you go downhill giving you back at least a good fraction of the energy expended in climbing up. But that produces a braking effect and the speed of descent is reduced. What inevitably goes lost is the energy taken by friction and wind resistance. Storing and using later is also subject to a degree of loss.

In short, if you don't want to use a commercial energy source to "fuel" your bicycle, get a conventional one - you'll do vastly better.

how do i find out the laws on importing goods from china to the usa?

best electric bikes usa on INTERBIKE 2010: INTERBIKE REPORT, PART 4
best electric bikes usa image



randybates


i want to buy electric bikes in china, and sell them in america


Answer
You need a customs broker. They know relevant regulations for each commodity. Chances are the only things you'll need to confirm regulation-wise are (1) whether you need to pay duties to Uncle Sam when you bring electric bikes in from China; and (2) whether electric bicycles require UL (underwriter's laboratories) approval.

For info on duties check the US International Trade Commission's Tariff Information Center at the following link:
http://www.usitc.gov/tata/hts/bychapter/2005_supp.htm
See chapter 87 "Vehicles other than railway or tramway rolling stock, and parts and accessories thereof"

Frankly if you don't know the regulations governing the importation of electric bicycles from China into the U.S., then that means you probably have no experience in this industry, and there are more important questions you should be asking, such as:
Who is your target customer and how will you get their attention?
Who are your main competitors?
Why will your target customers buy your bikes and not your competitors'?
What advantage do you have selling electronic bicycles that your competitors don't have?
How will you find suppliers?
Do you have the capital to buy bikes, ship them to the U.S., inventory them, and invest in marketing to sell them?

Keep in mind that suppliers in China only sell large quantities. Unless you are prepared to import full container loads of electric bicycles there is no point buying direct from China. You should first find a domestic wholesaler or importer to buy from, that way you can get your business started with a low capital investment. Your COGs (cost of goods) will be higher, but you won't need to tie up cash in inventory. Focus on developing your customer base and growing sales. As long as you at least break even you are doing great. Then, once you have built up a customer base and have sufficient demand, you can think about finding a supplier in China. When you're at that point give me a call and I can help you - 212-847-7175. Good luck!

All rechargeable batteries will suffer from this effect, called "self-discharge". It gets worse as the batteries get older. You need to buy some new batteries.

What is the best LED bicycle head light for every day after dark commuting in a city?




Jesus Hipp


I have a huge and heavy 16 LED flashlight that works well. But well, it's huge and heavy and the "D" cell batteries rattle... though they do last along time. Any suggestions? I'm not spending more than $30 ish. Need to be a quick release and usable with a handlebar bag in place also.


Answer
Try this light, it's a bit more money 34.95 but it will do what you want and the store will ship. You can get the phone number off the site. Power On Cycles, just too let you know its a Recumbent shop. Mark and Linda Powers are great to deal with.

Where can I find an electric motorcycle?

the best electric bicycle of the world image



A C


I am looking for an electric motorcycle under or around $2000 in CA. I want it to be sporty looking like a real motorcycle (not a bicycle) or look like the the Zero bikes. I also dont want to have to build it or anything. It also has to be street legal.


Answer
What you want doesn't exist. If you want a limited range electric motorcycle, be prepared to pay $17,000 for a Brammo or $11,500 for a Zero S. In fact, you are on the bottom of the cost scale for a decent IOC motorcycle. Suggest saving more money before you join the motorcycle world.
Good Luck

How do you ride the wacky bike that they have on the midway at fairs?




retrogirl_


World Wacky Bike. For $5, all you have to do is ride a bicycle 10 feet from a starting line to a finish line, and you win an electric scooter. The bike looks normal but most people only make it about 10 inches before they fall over.


Answer
Have you ever seen anyone successfully ride one? It might be impossible. You know they don't want to give away a scooter. I've never seen one, but I'd be interested in knowing, too.

best electric bicycle for hills image
Q. The only thing I've heard is that they even out hills a little. What else have you heard? Are they worth the high price?


Answer
You can buy a nice shop quality bike for the same price as a cheap electric bike. You will benefit from the exercise and be a lot healthier. Don't expect the batteries to last long on the cheap bikes so you end up with a 70 lb bicycle or ending up pedaling harder then a regular bike. Expect to buy a new battery pack every 6 months or so.

How much energy loss would be if I used generator and motor to propel a bicycle instead of pedaling directly?




cdr


I'm thinking of making a lightweight scooter that can be propelled by electric motor, but can be pedaled if the battery is gone. Instead of making the pedaling component main function, i want to pedal to store/generate electricity. Does this physically/electronically make sense, or would there be too much energy loss? What if I can find very efficient motor and generator?


Answer
About the best efficiency you can get with electric machines (motors/generators) is 90%, and this might be tough to find. Smaller motors are more likely to be about 80%. If you do get 90% on both, you can multiply 0.9*0.9=0.81 or about 80% total efficiency (ignoring friction loss etc. which you would have some of anyways). If your willing to pedal about 20% harder than a direct connection ... your good to go.

I have a couple of pretty big (about the size of car starter) 50V DC motors. When I hook them together and turn the shaft of one with my hand, the other turns almost as fast. They are pretty efficient ... so I think you have a chance.

Consider charging the battery with the motor as well. You could recover some of the power with regenerative breaking or when going down hill etc. and reuse it.

I'd do some efficiency tests with the generator/motor before you decide to build this thing ...

Dear Lime ..did it ever occur to you that I might have my reasons for asking!! Is that OK with you???
Thanks Bob Lahblah ..I was trying to get some informed information..but it seems the bike enthusiasts are not very nice people.



Answer
Legal Low Powered Electric Assist bikes are now becoming a great alternative for tens of thousands of commuters in the US. Use an ebike for commuting and save the price of the ebike in insurance savings and service costs, And still get a workout- no more time on that dreaded treadmill at the spa.

Some young fit folks may never need one, but, if you are one of the folks that really does not want to take their car EVERYWHERE, especially to just get a loaf of bread, Ebikes may be the thing for you.

They all have on/off switches and a way to control the level of assist. People might use maximum assist going to work, but minimum assist going home for a workout. If you have asthma or arthritis, an ebike makes the bicycling world yours again- on good days- minimum assist, on bad days - you still don't have to get in the car- just use more assist.

Fifty percent of households own bicyles but less than 5% of them use them regularly. Over 50% of households with ebikes use them on a regular basis.

Some people use their $2,000 racing bike as a roof ornament and a badge of being a yuppie. Other people take ebikes every where, saving lots of money, helping the environment, and stayiing quite fit. YOU DO HAVE TO PEDAL, other wise your range is really shortened.

Right now you can get an ebike that will go 30 miles, (with your pedal assist) make it up most any hill in most cities, feels like a normal bike, can bring home 40 lbs of groceries and has no more service issues than a normal bicycle -for about $1500. And have local service in MANY US cities.

There are today some really great ebikes, much better than 3 years ago. The Bionx, www.bionx.ca , has the most bicycle like feel, and great range. Cyclone, www.cyclone-usa.com , has the most power.
Crystalyte system kits have pretty good value
http://www.poweridestore.com .

In most US states, Ebikes are legally limited to 20mph under electric power, must have pedals that work, less than 750 watts of power, and 2 or 3 wheels (not 4), and are legal where other bikes are legal. Check your state though.

For reasons of test riding and long term support, it is highly suggested that you buy your first one from a local dealer, unless you like to work on such things your self.

The average ebike rider puts on more miles than the average regular bike rider. Why? Ebikes are more fun, less hassle, and there are just less excuses to take the car.

Many ebikes are also light enough to be put on many city busses and trains- helping with "multi-mode" commuting.

(But be careful, there is some junk out there)

What is the best kind of bicycle? The one you will ride.

Try the following yahoo discussion group for indepth information on specific ebikes:

http://tech.groups.yahoo.com/group/power-assist/

There are great ebike dealers in Texas, Colorado, Seattle, Georgia, New York, California, Kansas, Illinois, Utah, Nevada; the list goes on and on.

best electric bike for steep hills image






I'm 14, about 1.68m and 65kgs. I want to get a dirt bike to learn to ride on, and to ride around my farm. I was thinking something like a Honda CRF 230F, or something like that. I have never ridden before, but I'm a fast learner, and am pretty good at driving quad bikes. Also, if it matters at all, I'm a girl.
Please help?



Answer
You could go for a 230... They are big bikes though and have a lot of bottom end power.. but not much top end... great if you want to slowly power up a steep hill.. not so good if you want a bit more speed and power at the top end.. I personally would get like a Suzuki RM 125... they are light, fast, ALOT of power.. especially at top end.. cheaper, easy and cheaper to fix... the 230 is big and heavy.. the upsides of it are electric start and you are less likely to flip it on a steep hill... but for fun (disregarding safety) id go for a light two stroke machine :)... You will probably flip the 125 up a steep hill though.. especially at first.. but yeah.. its alot cheaper and easy to fix.. lighter as well.. just be sure to get the fuel to two stroke oil mix correct and dont use a cheap oil.. it will wear out your piston rings... To be honest ive ridden plenty 230's... i got board real quick.. but if you dont mind a bit less speed and adrenaline.. go for it :) hope i helped.

Does anyone have any experience of a Synergie Extreme E-Bike Mountain Bike?




Essex Ron


I am tempted to buy an electric mountain bike but don't know anyone who has one.

Yes, I KNOW it's better to cycle, but I do plenty of exercise and want to use an electric bike as an alternative to the car now and again.

So are they any good? What is their range? And do they cope with hills?



Answer
they are a piece of S@*#. They don't go up a semi-steep hill and they don't go to far on hills.

Are electric motorcycles cool?

best electric bikes of 2013 on cars girls and 2013 cars wallpapersvectrix electric super bike
best electric bikes of 2013 image



BobbleColo


So, I am shopping for my first motorcycle. I was looking at a few bikes. A Ducati Monster 696, a Ninja 600, and a 2013 Zero S (not 2012). The 2013 Zeros have different motors and batteries that give it near 600cc equivalent performance and a 130+ mile range at a top speed of 95MPH. I am a huge EV enthusiast and I currently drive an all-electric car. I'd love an EV motorcycle like the Zero S, but there is one very important factor to consider... the "cool" factor. Do you think EV bikes like the 2013 Zero S are as cool as those other petrol bikes? Or, would the ladies be more inclined to hop on the back of a noisy ICE bike?


Answer
You have an all-electric car -- you are already totally un-cool. Nothing could make you cool so you might as well get a Zero.

Californians: do you agree with the liberals that run our state that we do not pay enough for gas?




You're Wel


http://m.utsandiego.com/news/2013/feb/28/gas-tax-california-rise-july/

I paid $4.21 yesterday but luckily it will be my last tank since I got a hand car that will get me from point a to b as long as these points are near the railroad lines.



Answer
Liberals don't care how much we pay for gas... They want us all to ride bikes, electric scooters, fly on magic carpets and whatever else liberals do. Gas prices suck and so does this state. Sick of this state and its controlling govt with high taxes to pay for more dumb programs and have them tell what I need and don't need. California needs to split 3 ways, north, south, and Bay Area. All the libs can stay in the bay and have their way, republicans up top, dems down below, everyone's happy and the libs aren't making legislature for anyone but themselves.

csmuch41


i wanted to make an electric bike but i dont know how to make the chain spin... how does it work?

does electricity and battery make it spin or what how does this all work?



Answer
You are right. An electric motor and battery are what is needed.

But most electric motors are either direct drive in the rear hub OR there is a roller that drives the front wheel directly. With your level of expertise I'd recommend getting a kit. Australia do some good ones.

Good electric bikes start at around $1500 and go up from there. Even decent conversion kits are about $1000. Anything lower than that price point will be a slow, disappointing, heavy pile of junk.

Just sell your car, you aren't responsible with a motor vehicle anyway.

Why have ebikes, electric mopeds and electric scooters largely disappeared from North American cities?




sally


Who is "killing" the Electric Bike (aka Electric Scooter) in US and Canada? Many retail shops have closed, from Boston to Vancouver. North American manufacturers (Nova Cruz, Wavecrest, Bionx, Egovehicles) have gone under or are selling much less than they did before.

In comparison, in most of Asia, sales of ebikes are surging? Is it the economy collapse? Is it government? Is it the big auto companies? Is it battery companies? Is it some other factor?



Answer
All these smaller vehicles are disappearing mainly because of our affluence. As all the household get affluent they do not want smaller bikes and cars and go for bigger ones. Also it creates a fashion and so the not so affluent also aim to buy it. In due course there is no takers and they die a natural death.
Take the case of China where a decade ago there were thousands of cycles in the main cities and now they are all replaced with bikes and cars. So is the case of India. Once it was having a lot of 100 cc bikes but now it is n the decline. So it is the life style and not the government or oil companies who are responsible for it.
