Electric bike power

[sikeston34m]

The little 3032 isn't really designed to handle 36 volts. Remember it's going to be carrying a pretty big load. (your butt) LOL

I played around with this idea using several different outrunners on 4S.

I used a 1" Diameter rubber Wheel and put it in a Prop Adapter for an Airplane. Then used one of those touring bike tires on the front, looked almost like a slick for the best contact.

I made a spring loaded motor bracket that would apply constant pressure between the drive and the front wheel.

A Quark 80amp Esc and a Servo Tester to operate it with. It had a little dial to turn it up and down with.

The 3520 would carry me about 20mph for a couple of miles on 4000mah. Then I tried a Century 600 plus, a 3530 I believe. It carried me up to 28 mph for a couple of miles. But both motors ran really hot and wouldn't have held up to this kinda treatment for very long.

Get one of these. http://www.unitedhobbies.com/UNITEDH...idProduct=5139

It's 12mm shaft is very close to the standard 1/2" 1/2" converted is 12.5mm fyi

Being rated for 7000watts, it will put out over 9hp. The price isn't bad either. In fact, I have one I'll sell/trade you if you're interested. On the condition that you let me know how this all works out and by all means, don't get yourself hurt. LOL

For Power, 10S A123 is the way to go. Their Tough and are gonna give you good cycle life. Charging this isn't really an issue. Just use the factory Dewalt Charger Base.

I'm sure you've been inside a few packs like I have to gather cells for other projects. You can use one empty case with the Battery Management Circuit inside to charge the entire thing.

Leave the Circuit inside the Case and jump off the power leads to your own connectors.

If balancing is a concern, you can make your pack parallel by jumpering between each cell. Then carry these connections to the single Battery Management circuit that's transferring power from the charger.

These are some of the ideas that I thought about putting to work on this.

The big outrunner probably has enough torque to drive the rear tire with chain drive. I was thinking about mounting a stepped sprocket on it so I could find the ratio that it operated at best. Have it take the place of the regular front sprocket, and retain the gear changing ability if I could.

The big motor should be able to put out enough power to go as fast as you care to go. It's all a matter of how much juice you wanna feed it. LOL

I bet it would really accelerate hard too.
