It was funny to see that they seem to build their own battery packs, just like when you are doing with professional radio controlled cars. They are already thinking of regenerative braking, probably using the motor magnetic field generate electricity and drag to slow down. From what I understood, they are facing some issues with the sensibility of the throttle, which gives 100% power right of the start, also unexpectedly when you bump or tip the throttle...that's a major issue. The electric motor doesn't make any sound, and because there is no clutch, there are great chances to accidentally hitting "the gas" when you are of the bike. Anyway, I think that is in general a good design challenge also. They are using electronics from BMS, which I didn't know before. (http://liionbms.com) Through their website I also found out about the EVForum which is a forum for discussion on electric vehicles with lots of infos. (http://www.evalbum.com/) Great link man, thanks a lot! put some pictures up of you testing the KTM electric motorcycle! Hey Piers!! great link man! so interesting to see their work.

Was soo good. hope your well... Hey, I saw this today somewhere else and thought I would check your site because I found quite a good article abotu converting an mx bike into electric:

The first one is constructed just like a standard motor except it doesn't have any magnets and the other is more like a piston engine. They are extremely efficient motors as they do not have any back emf, plus you can extract electrical energy from them using the fly back voltage in the same way as the bedini ssg. You might be interested in watching the "Electric Motor Secrets" dvd with Peter Lindemann where he explains the principles. I think there may be a torrent for it floating around thoguh don't tell Peter I said that! Good luck with your projects!

I wonder how small such motors can be. Hub Motors are really practical, I think they are great, except for some ballacing issues if we ever get the chance to build a offroad fun version of a moped. Because of the added weight on the wheels. But for zapping through the city, I can be for sure an option. PS: I pasted the youtube code on the "code Tab" under posting, than it worked, probably embeding YOutube videos on the "Visual Tab" doesnt work. Nice Piers!
