nope, not enough power from 1/3 hp motor to haul around 200Lbs, for very far / or fast enough to worry about pedals. i need to build another one, on same frame.

i was a china scooter motor, 250 amp... it is too small. worked but too small for any kind of usage... a big electric motor can be found cheap, however, you have to match your battery power to it, and gear ratio.

[Somedood200]

NOT AS EASY AS IT SOUNDS... key to a usable electric bike is a brushless motor in-side the wheel.... about $350.

torque is all about gearing. i rode it down the road, went about 10 mph, depending on hills. power in bats is the ONLY limitation. i played with 18 volt bats and got a little more out of 1/3rd hp motor but yes, 1/3rd hp is not enough to realy enjoy an electric bike.

i have a nice GIANT, ride all over the place on bike-trails. i still have schwin in video. it has a 24V john deer alternator on it. i lost interest when i could not get enough HP out of weed-eater engine to run alternator. still want an electric hub and lithium bats for GIANT. cars, houses, and riding lawnmowers must be for foolish and lazy people also, using your stupid analogy.

[Somedood200]

to ALL- yes i have bike. it is in a pile in garage.it has 24 volt tractor alternator attached from when i was trying to use weed-eater motor to power bike electricly. 1/3 hp engine did not cut-it. yes it is suppose to be an idea on how to make very cheap electric bike. limits are your abilities! it slows enough from pushing body weight that pedaling is not a problem.

@deidara633 ummm? its a bike with electric motor that is functional as i have ridden in 5 or 6 times, and i paid $30,... "how is that misleading?"

[joshbulldog1661]

that looks deadly

Nice design. But for those of us with less imagination, how about some instructions?

[ncranfill]

From what I can tell (postings) the power desired it insufficient. Try this out: Amplify the voltage as high as you can, add capacitor setup for rapid impulses and feed it through a high voltage spark gap. Try out magnetically quenching the gap and/or combine with vacuum tube. The results should provide an enormous output. Enough to charge the battery and power the bike as well. The faster the Impulses and higher the voltage through the gap the better. Don't knock it till you've tried it.

Hope you're not using stock or cheap bike tires on that. Those things are going to blow on you at high speeds (not an if, but when), and the result will not be pretty.

[EvoMitsubishiLancer]

can you teach us, how to build one: part we need?

[fdsman]

@Somedood200 it's misleading because the pedals are still being driven by the motor, if you tried to rest your feet on the pedals you'd probably stall the motor and flip yourself onto the street. You need to be driving the cassette, not the front chain ring.

[metrion99]

your feet go where?....

America is getting more lazier as we speak :o
