Will pairing two 36v electric wheel hub bikes together = 72v to go uphill?




Oiseau Ble


If I pair two 36v electric wheel hub bikes together, with a frame of some sort, (a quad bike) will I get the equivalent of 72v to go uphill? These hills require 72v for electric bikes. Or will it be just two 36v bikes coming to a stop 1/4 the way up the hill? Is it like two batteries in parallel, or two batteries in Series??? Anybody?


Answer

72v will melt your 36v motor by the way

Is electric bike easy for someone who has never ride on a bike before?


Answer
NO! The extra weight of the battery & motor will just make it more difficult to learn balance. For the price of just one electric assist bicycle - you could buy three to four really good pedal bicycles.

Electric assist bike - http://www.trekbikes.com/us/en/collections/electric_assist/t80_plus_gl/#
Fitness bike - http://www.trekbikes.com/us/en/bikes/road/fitness/fx/7_2_fx/#

$2,099.99 or $549.99? Your choice. I'd take the $550 bike. It'll last longer too.

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

10 best electric bikes on Electric Bicycle - Selling Leads, Manufacturers, Suppliers, Exporters
10 best electric bikes image



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
Yes but you will go slower because you are turning the motor so basically there is no piont unless you modify it yourself

Can an electric motor take different voltages?




SILVRSWT


I am interested in buying an electric bike that has 2 batteries that opperate at 12v @ 10 amp hours. They are designed to work together to deliver 24v to a 450 watt (peak) motor at the front wheel. Unfortunately these are heavy SLA batteries, and I would like to replace them with state of the art Nanophosphate Litihium Ion batteries.

Now the kicker: I can only find 36v versions for use in DeWalt power tools (though they are very energy dense).

So what I am wondering is if I can buy 2 / 4 of these and wire them to deliver no more than 36v continuous to the 24v motor and will it improve performance or just burn up the components.

Also as an added question, if it is not possible to run 36 volts directly is there a controller that could accomplish this.

Thanks!

The motor is from Currie Technologies, specialists in electric bikes.
I should add that the motor is DC as will be the current delivered to it.



Answer
Just replacing the 24V pair of batteries with a 36V group will very likely cause something to fail. It is possible that a controller could be designed to allow a 36V group of batteries to work with the motor, but it isn't something that you are likely to be able to easily find and mate up to the existing motor.

Additional information:
If you get a 36V PWM controller and set the current limit to the maximum continuous rating of the motor, that might keep you out of trouble. If the motor has a higher short-time current rating that you want to utilize, that might be difficult to set up.

Look at: http://www.dartcontrols.com/

More additional information:
It looks to me like Currie Technologies offers some models with a 3X12V 36V battery package, 36V controller and 450W motor.

in your opinion how many persons needed for this bike generating electricity to help a whole city?




iojhyt675


a bike exercise that generates electricity for home use. if a small city wants to generate electricity by these bike exercise generating electricity, how many persons needed that will feed 1,000 homes with electricity such are for A.C. and heater, TV...etc
the video on youtube will show you what i mean, or search for "CYLEC" Electricity Generating Exercise Bike : DigInfo
http://www.youtube.com/watch?v=HjVYBAicVKU



Answer
A typical person can produce about 100 watts over a sustained period on one of these things (this is a limitation of the body, improvements in the generator will not change it), but not 24x7. We need rest periods. (Even marathon runners have to rest after the marathon.) Only the very fittest individuals can do better than this.

(You doubt this? Cranking a generator under load is HARD. A lot of science and tech museums have a hands-on - or feet-on - exhibit where they have one of these things set up with a power meter. Anyone interested in energy should go and find out how tough it is to produce 100 watts.)

But let's say we employ only Tour-de-France class athletes. They've been measured at 300 watts output over a one hour period. I doubt they could do that for 8 hours straight... but let's assume they can.

So over an eight-hour shift, one of these people might produce 8 x 300 = 2400 watt-hours, or 2.4 kWh.

The average home in the US uses a *round-the-clock average* of just about 1000 watts. That's 24 kWh per day.

So you need 10 workers - all of them Tour de France-level athletes, each working one eight-hour shift per day - to produce the electric energy for ONE average home.

But, assuming they live three to a home, you have to add 3.3 homes to the city! It's a net loss.

Even if you assume that each can work 16 hours/day instead of only 8, you still need 5 workers per existing home... plus you have to power and light the houses those workers live in. Even if they pack themselves five to a home it's merely breaking even.

AND you have to feed them all. Even Tour de France cyclists have to eat. The more energy your body is producing, the more you have to eat. And the body is a relatively inefficient converter of food energy to mechanical energy. But assuming it was 100% efficient, to produce that 2.4 kWh of energy would require eating over 2000 calories' worth (large calories, or kcal) of food *in addition to* their normal consumption. That's by direct conversion of units. In practice (due to inefficiency) it would be much larger. Nothing in energy is free, not even human muscle power.

But, damn! They'd have legs like tree trunks...

pmk is dead on with that one. Go sit on a CRF150F and a CRF230F to see which is a better fit. Then if you don't want to buy a new one, search cycletrader.com for a used one in your area and price range. I have ridden the 150 and owned the 230, both are super fun easy to ride bikes. All of the 230 year models have electric start and the 2008 150 also has it. I think previous 150's were kick start only.

I want a safe car for the winter time, what would you prefer?

best electric bicycle 2012 on Best Electric Bikes For 2012 - MetaEfficient
best electric bicycle 2012 image



Thistimear


Including 4 wheel drive and not being a truck or anything huge that wastes a ton of gas, or something super expensive- 18k price range.


Answer
There are no "safe cars" for any season of the year around the planet. Cars are not safe. They are motion, self propelled devices powered by internal, some say "infernal" combustion engines, albeit many new ones have electric motors, Yeah! Four wheel drive vehicles do not work if there is no friction. In fact, 98% of cars on the road ARE NOT four wheel drive and are driven year round rather successfully. The DRIVER , the knowledge, the training, the ability to think and judge the conditions is what is important and evolves to a safe driver. Plenty of 4X4 crash in winter as this has NOTHING to do with handling, braking or ability of the driver to use good judgment. Years ago when ABS came out insurance companies gave a discount as they though cars with ABS would crash less often. THEY WERE WRONG. When cars came out with Stability Control Programming, no discounts. Do these cars crash less? No they do not. As it happens, most people DO NOT EVEN KNOW HOW THESE WORK and crash anyway. Why? Because people take RISKS. In Kentucky alone in 2012 over 53,000 crashes were attributed to distracted driving which means texting/cell phone. Three days ago in my area an 18 year old female died when while texting lost control of her car and crashed. About the same time a mother of four kids, barely 26 years old, drove in front of a large, YELLOW, school bus as if this BUS did not exit. She dies. Cause? Texting. If you wish to buy a car, buy a car you want. However, get driving lessons. Most people DO NOT KNOW ENOUGH as to cars. Going to a driving school should be MANDATORY. If you wish to see what I mean go to "wreckedexotics.com" to see people with money to buy expensive cars but with no brains to buy driving lessons that have crashed their cars. Some die. The subject of tires, energy, handling, kinetic energy, stopping distances, etc. IS NEVER DISCUSSED. And so, you, in your state of being an average uneducated and untrained driver, have the opinion that there are safe winter cars? And you shall buy one but you shall crash THINKING that you can speed and mishandle the car because you have four wheel drive. Last year or two an author rode a model T Ford for one year. In that year there were over 8 million crashes, 40,000 people died 5,000 of them teens. With millions of injuries over 250,000 ended up with handicap level injuries. This guy? Not even a parking ticket. No heat, no radio, very small almost bicycle size tires. And yet, not a scratch on the car. Why? He knew how to drive and when to drive and where to drive. No chances. My 2001 Audi is front wheel drive. Five speed manual. I drive year round. If there is snow, seldom in my area, over two inches, I wait for the roads to be cleared. The car does not have a scratch on it. Why? I have taken driving lessons, I never speed and I seldom take chances on the road. People have tried to crash into me. They speed, do not stop at stop signs, tailgate, etc. But I know what do to. How about you? Care to evolve into a safe driver? Get lessons. The car is not that important. YOU ARE.

Has the "BP"(ARCO) oil spill made the 2012 destruction of planet Earth a reality?




guitarohol


Is it possible the global corporate community is hiding the devastating truth?
Will the destroyed eco systems cause all of the others to fail?
How many new jobs will be created to get the cleanup done?
Where is the public outrage?
Would a boycott of ARCO gas stations wake up British Petroleum?
Wow! Impressive answers. Seriously, I appreciate all of the answers because they tell me good people are concerned. I award thumbs up to all answers and will choose the best one... Thanks again.



Answer
No, the "BP"(ARCO) oil spill has not made the 2012 destruction of planet Earth a reality.

When someone says, âI want to boycott BP,â the person you wind up hurting is the guy who lives in the community, buys the pages in the high school year book, and the cookies from the girl scouts.

What I think they ought to do instead isâ¦start walking.

In other words, boycotting certain gas stations only stands to harm individual gas station owners, not the larger company. Thatâs because individual stations that have the BP logo on them may or may not buy from a BP gas distributor. More importantly, stations that donât have the BP logo are just as likely to buy from a BP distributor. A host of liberal media outlets, from the New York Times to Time magazine, have pointed out the futility of a boycott.

the only way to really ensure environmental safety is to boycott oil entirely.

But it doesn't even end there. So you buy a plug-in electric car. But that energy you're charging it with could come from a power plant burning natural gas. And, oh wait -- according to BP's website: http://www.bp.com/sectiongenericarticle.do?categoryId=3050046&contentId=3050873

Today, natural gas makes up more than half of BP's energy production, making us the largest producer and supplier in the U.S. In fact, the metro busses here in DC run on natural gas, so perhaps public transportation is out of the question as well. That leaves your bicycle and feet. An inconvenient truth, indeed.

In the real world, no matter how careful you are, accidents happen. There's always the possibility of human error, and sometimes even machines and computers malfunction. So long as an ecological disaster is possible, no matter how improbable, you have to be comfortable with the fact that it could happen.

That's not to say that BP (and probably others) shouldn't have done a better job in identifying more effective disaster containment. It just means that if we want to live in a world where we consume energy and resources in the way we do, we must accept the possibility that, from time to time, things go very badly. We certainly don't have to like it, but we can't pretend that boycotting one company will change very much. o_O

What is the solution to Seattle's traffic woes?




Rainier


Seattle area commuters are looking at billions of dollars in costs to replace 520 and the Alaskan Way Viaduct. But these megaprojects don't even increase capacity. What do we do to unjam our clogged freeways? Your ideas?


Answer
1. Build a bridge or tunnel from the Seattle waterfront to the ferry terminal in Winslow.

2. Replace the Viaduct with a tunnel, which would be tied into the new bridge or tunnel to Winslow.

The technology for both projects exists today.

3. Starting in Everett, have a light rail line that when not on former railroad right of way... bike trails... would run down the center of I - 5. starting at the Everett Mall, to Alderwood Mall, Northgate Mall, utilize the downtown tunnel, stop at the Sports Arenas, South Center Mall, SeaTac Airport, SeaTac Mall,link with the Tacoma light Rail, Tacoma Mall, swing along the new Rt 16, over the new Tacoma Narrows Bridge, and stop along the way at major Park & Rides and the Kitsap Mall in Silverdale.

It could have Park & Ride lots built all along the rt.
By stopping at Malls, you have a ridership base almost instanly. These are existing major destinations with parking as well.

4. Build a light rail line along the entirety of I-405, runing a loop service in both directions, linking to the line being built now, and extend the currently built on to Auburn along 167, then tru an existing abandoned Electric Rail Interurban Tunnel, connect to the Tacoma Trolley and the Everett/Silverdale line.

5. Replace some ferry crossings to bridge or tunnel, such as Edmonds - Kingston and Southworth - Fauntleroy

The ferries are nice as a tourist thing but are really obsolete.
They are expensive, slow and infrequent.

What is the lifespan of an electric bike?

best electric bike hub motor image



archa_pyus


Say you have an electric bicycle that is used daily, capable of a 30 mile range before needing re-fuelling and a speed range of 3-15mph.

What would be its likely lifespan, i.e. when would the whole thing have to be replaced?

I do not need exact measurements, just the general idea, as it is for a project for which i have to design an electric bike, which i know nothing about.

thank you!



Answer
The life span of an electric bike is mostly determined by the battery. Batteries can have a memory and if recharged before depleting it completely will reduce the capacity and can affect the range.

I would do some research on batteries. You can also look up motorized hubs to put on bikes, they make for the cleanest design.

Motors are rated in watts and most states have regulations that control the maximum amount of power that you can use.

How can I figure out how fast my electric bike would go?




morbeckbra


I'm trying to put together an electric bike, with parts from http://www.electricscooterparts.com/. I'm using a standard bike frame that weighs about 30 pounds. How can I calculate how fast a hypothetical electric powered bike will go just from looking at the voltages and amperages of the batteries/motors listed on the website?


Answer
wrong data. you need motor rpm and drive train ratios. voltage and amperage gives you power, watts or horsepower. which will let you figure how long it will take to get to top speed.

example: a hub motor with no gears, running at 250 rpm will move a 26 inch bike wheel at about 20 mph.

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.

What happens when you don't tighten the battery terminals on a bike and start it?




Candace


I trickle charged the battery on my bike and put the battery in just to see if it would start but I didn't tighten the terminals. The dash lights turned on and when I went to hit the ignition, it sparked and then absolutely nothing. The dash lights will not even turn on now.
No fire! I didn't fry anything did I??
Thanks guys! I got it figured out! Just needed it to be tightened and it was able to start.



Answer
If you didn't tighten the battery terminals:

The small area of metal contact between the battery post and your battery clamp carried the small amperage current required to light your dash lights. When you engaged the small amperage circuit running to the starter relay it had enough amperage to momentarily close the relay but when that high amperage circuit to your starter closed that high amperage load heated the small contact area between your battery post and battery clamp melting the contacting metal area and leaving oxidized metal behind.

When you remove and wire brush the melt pitted and oxidized affected battery post and clamps and firmly tighten them all should return to normal.

When finished buy some battery terminal sealer, it's no more costly than a can of spray paint, less frustrating and messy than smearing grease over the posts and clamps and if you watch it will make water bead up around the terminals instead of soaking in or dampening the post / battery area.

I am looking for an electric bike for exercise for under $500. I want electric because my area is very hilly and I want to get exercise but I'm just not in shape enough to make it up the hills without some help. Ideas for the best in my price range?


Answer
Forget the electric bike they are hard to pedal and using the motor wont give you any exercise. If you want exercise get a used stationary bike off of Craig's list or better yet go to the local bike shop and get a good hybrid bike. It will take time to be able to climb hills, if you have to get off and walk.

What TRIAL Motorcycle should i go for?

I'm 17 and i wanna get a trials motobike

I need something cheap and good for a beginner, i'm average tall, not too tall and hell no im not short
125cc, 200c 250cc 1000cc? lol what are your suggestions for a bike? and what should i know about the bike before buying one

PS: im not attending any club for training, im doing it solo :P



Answer
If you want to ride trails. Get a 4-Stroke. Start out with a CRF230F, TTR230, XR200 ect. Its well worth it to get one with an electric starter, they really help when stranded on a hill climb that you stalled on :)
The XR200 will be the cheapest on the list, you can pick them up all day on craigslist at $500 and above :)

You also mentioned that you wanted a Trials motobike. These are different.
Trial motorcycles are distinctive in that they are extremely lightweight, lack seating (they are designed to be ridden standing up) and have suspension travel that is short, relative to a motocross or enduro motorcycle.
Its like Parkour for a bike :)

Hope this helps!!

Thanks!

Karl



Answer
Motorizing isn't the problem. The problem is that there isn't a bicycle out there that is safe at a speed faster than what you can pedal and mostly because of the poor quality of the brakes with which they're equipped. When I was stationed in 'Nam they had some hybrid bicycles which you started off pedaling and then pulled a lever which dropped a small motor down so the small wheel on the motors output shaft contacted the front wheel of the bike and turned it. Even though it had a better braking system than a standard bike I saw a lot of young ladies (which was mostly what rode them) taking some real nasty spills when they couldn't stop in time at intersections.
Also a buddy of mine, back in the early 50's had a motor bike which was built by the Schwinn Corp. It used a belt drive on the rear and had decent brakes, similar to a motor cycles.

Even if the theory of global warming is wrong, to have approached global warming as if it is real means energy conservation, so we will be doing the right thing anyway in terms of economic policy and environmental policy. -- Timothy Wirth, former U.S. Senator (D-Colorado)

We are living in strange times. One exceptionally warm winter is enough--irrespective of the fact that in the course of the twentieth century the global temperature increased only by 0.6 percent--for the environmentalists and their followers to suggest radical measures to do something about the weather, and to do it right now.

Rational and freedom-loving people have to respond. The dictates of political correctness are strict and only one permitted truth, not for the first time in human history, is imposed on us. Everything else is denounced.

NewsAccording to the new data published by NASA, 1998 is no longer the hottest year ever. 1934 is.

Four of the top 10 years of US CONUS high temperature deviations are now from the 1930s: 1934, 1931, 1938 and 1939, while only 3 of the top 10 are from the last 10 years (1998, 2006, 1999). Several years (2000, 2002, 2003, 2004) fell well down the leaderboard, behind even 1900. (World rankings of temperature are calculated separately.)

Can we use FI system in place of a carburator ina four stroke petrol engine?




Chinmaya R


I want to know that can any indian bike which are using carburator will be replaced by a fuel injection system?please suggest me.


Answer
yes. in theroy. if you can find one that will work/adapt to this. but it will need a programed fuel mapping computer and air intake/fuel monitoring sensors to deal w/ advance fuel curves. the fuel advance curve will be typical to spark and cam curves. along with an electric fuel pump that is rated for the app.

"please suggest me."

best to just rebuild the carb. and if this bike is from India, good luck with that. finding a kit in N. America.

You have the best idea. Because there is no any kind of air pollution or sound pollution while using the electronic bikes, electronic motors. You can buy it from the bike showrooms. These kind of stuffs are rarely found in the present world. Best of luck.

I'm wanting to buy an electric hybrid bicycle. looking at the Victory folding electric bike. anyone own one?




jane_doe_e


the whole product description is- Victory folding 6-speed 180W Power Assist 12"/16" electric bicycle. it is sould through amazon but absolutely no customer reviews can be found anywhere. not asking much for the price, just wonering if it is a complete lemon.


Answer
I did not see the ad, but I can tell you 180 watts is nothing. we have a 750 watt limit here in the USA for a reason.

Europe has a 250 watt limit and everyone is complaining there.

I80 watts is too small, it borders on being a toy.

found the ad:
However, for the price, if you are a smaller person (under 150lbs) and will pedal a lot with it, it just might be OK.

I like e-folders, and want one. I have every kind of ebike in the shop, if I was not in the trade, I would be tempted by this. Oh and wasn't 6'2" and 230lbs.

its competition:

Can you hook a 48 Volt Battery to a 500 Watt Motor on an Electric Bike?




EDIT K


I'm trying to make my Electric Bike go faster.
I want to run the Battery directly to the Motor, will this work?
Can I do anything else to make it go faster?



Answer
A "500 Watt motor" doesn't give any information as the voltage that this motor was designed for.
If you increase the voltage significantly, you will surely burn out the windings in the motor - and it won't take very long either.
