Thanks for the advice all.
Knoxie, your bike is the one I saw several months ago that made me get interested in doing this and I couldnÃ¢â‚¬â„¢t remember where I saw it. I think thatÃ¢â‚¬â„¢s more than what IÃ¢â‚¬â„¢m looking for though!
So after watching the video and looking at power requirements I think I may be interested in maybe 20-25mph at 5mile range as light and stealth as possible. I weigh about 76kg. I like the BionX because of the lower weight now but I wouldnÃ¢â‚¬â„¢t mind piecing my own components and it looks difficult to do with the BionX.
IÃ¢â‚¬â„¢m not an expert by any means I just know enough to respect lipos and that VxA=W. That Truerc.com looks like a good site, I used to order stuff from radicalrc.com but I donÃ¢â‚¬â„¢t have a charger anymore. IÃ¢â‚¬â„¢m up in the air on all this stuff. I didnÃ¢â‚¬â„¢t know the A123s were expensive, I thought they were cheaper than lipos. IÃ¢â‚¬â„¢d like some batteries that would fit or that I could take a part and stack in the triangle and cover it instead of having a battery Ã¢â‚¬Å“boxÃ¢â‚¬Â.
So a 250 watt motor on the rear with a 20 amp controller should do the trick? Will 24 volts work or do I need to go to 36? So with my lower speed requirements what type of batteries would have the best chance of fitting in there?
