Electric Bike?

Q. Hey I'm going to be moving a ways away from my kung fu school. So I will have to bike there but we are talking like 30 miles away at least. So my question is if anyone knows what that bike adapter kit is where it lets you switch between pedaling and driving?

Answer
there are allot of electric bikes and kits out there, but the problem is weight, performance, and distance per charge, remember, if you use those batteries for 10-20 Miles they are bone dry, and you have to pedal with an additional 80 pounds of weight, so you think, i ll add more batteries, but then you add more weight, then you need a bigger motor, so on and so forth, to have a more efficient setup you would need lighter batteries that last longer, lithium ion, or nickle metal hybrid, but they are very pricey, and you would need allot of them.

electric biking is not yet a transportation alternative, unless your going very short distance.

but if you wait, I'm currently working on a revolutionary concept for power assisted bicycles that will be available on the market for the summer of 2007 and will give you a 250 mile autonomy, and will only add 9.2lbs.

Are electric dirt bikes safe for 10 year olds?

Aaron

i want to know if electric dirt bikes are safe for 10 year old boys

Answer
Yes, they are very safe they have a top speed of 10-15 mph and they are very low to the ground and you can out run one easily. They are very good training bikes to get them ready for the bigger ones. But i would suggest them to a 10 year old.

How reliable are electric bikes?

bob

Answer
the biggest problem with electric anything is battery power. The technology is coming, but its not there yet, and the big reason is cost, it takes millions of dollars in research to make something small enough, with enough power that is stable (not likely to EXPLODE) THAT YOU CAN make portable, Right now range equates to wieght , and who wants to carry 1,500 lb battery packs around? not me.
The technology is coming, its not quite there yet, the next 10 years should be interesting, as the greedy oil strangling govornments fight over dwindeling oil supplies, where will the battery powerd technology take us Especially in the UNITED STATES. WE are making big advancements every day, but this must be met with caution, we are not where we need to be with battery technology yet.

Electric bike engine questions.?

Boss

ok so guys, recently iv thought hey, why not put an engine on a bike..
now my first problem was electric or fuel. iv chosen electric since it is quiet, no fuel, easier etc.
but.. i have no clue on what 'sort' of engine, whats big enough to push a bike along. i really dont need to go fast maybe 10km/h or 20km/h. Maybe even, just helpout my pedaling. i understand batteries, and connecting to the wheel. what engine do i need? hopefully under $50.

Thanks guys, if none of these are any good could you give me the link? I'm Australian/

Answer
ha ha

none of those will work

why not google 'bike electric motor' and just buy a kit for $200?

though i don;t recommend adding motors or engines
the kits are crappy
but you will never do it on your own
or for $50

--good one
this will weigh more than your bike
and need a car battery
what are you smoking>?

Can 13 year old drive electric bikes or scooters?

10 best electric bikes image

Caroline

I really want a electric bike for my 13th but my mom says I could kill myself on one! I would ride on side walks and "easy" roads just to school and my friends house (I live across the street from my school). I know the limit is 20 mph for driving one, and my max would be 15 and more like 10 on sidewalks that aren't busy. Is it legal to ride one in South Carolina at my age? Should I forget about it?
I REALLLLLLY WANT ONE!

Answer
Yes if it's electric and uses the sidewalk anything that requires gas and the roadway traffic you need a driving license!

Can I use motorcycle batteries with electric bicycle?

Valerka

Just want to save money on gas by going to work and back home (almost 40 miles per day) I don't mind putting a few batteries onto the electric bike (to meet the voltage). Do you think that is possible?

Answer
You will have to do a little research yourself, but a quick look it seems that a electric hub on a regular bicycle, capable of 15-20 mph, capable of 10 miles, would take a pair of 10AH 12V SLA batteries. For your capacity you will be looking at a pair of automobile batteries.

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

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.

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

Answer
There is already such a motor on the market. The name escapes me right now but it is a hub built into the rear wheel and it costs about $2000... not the Erbike hub motor... I think it is Electricrider or something like that.

To your request, yes, it is possible and a project I am working on right now. No, I can't and won't divulge details but CAN tell you that you'll see it relatively soon and it WILL be expensive- more expensive than a small motorcycle at this point.

By the way... I typically commute 24 miles (one way) to work on a bicycle, no problem. 5-10 mile commute is simple for most committed riders.

What form of transport is cheapest and efficient?

10 best electric bikes image

Anna

Hi!

Wondering if anyone has any ideas. I have M.E pretty bad and need some form of personal transport as i can't walk very far anymore.

I don't have enough money to learn to drive/insure a car so have been considering either a scooter or an electric bike....or any other form of transport you can come up with!!

My budget is up to £700, and I only need to make fairly short journeys, say up to 10 miles :)

Ideas really welcome! Thanks!

Agent Ginger

Answer
Not sure how bad you have M.E. but what about a electric push bike will keep you fit and if you get tiered switch too electric and go with the flow! On another note visit Forever Freedom products on the web there is a Aloe drink which could help your M.E. I know it has with others.

Will a 12v 12mA electric bike battery be safe to connect to my portable guitar amp?

Ben K

I I have a Peavey Solo amp, 10 watts output, that runs on eight 1.5v NiMH batteries. I want to connect just one 12v battery, but what type do I need? I don't want to under power or blow the amp!

Answer
If you can get the polarity right, it should be fine. 12 volts is 12 volts, the only time you would worry about current would be if your battery did not have enough.

By the way, your bike battery is probably 12 volts @ 12 amp-hours.
