I usually ride the bike for about 1 hour before I can detect any power loss, which means its done. I could add more battery capacity but I really like the light weight and my old body is pretty hammered after 1 hour. anyways.
I've built a lot of electrics, cars, bikes, trucks, etc and the first question is ALWAYS how long will it run. And there is never an easy answer because,just like a gas engine, it depends a lot on how hard you ride. But for me anyways, the run time is more than adequate, but I don't compete. There are other issues that would need to be addressed if one wanted to run with the big dogs. But as you all know, there is a big gap between just riding for fun in your back yard VS a pro event. For instance, I did not concern myself with water issues. The motor is quite exposed which helps with air cooling but would certainly have issues in competition.
When I look at the designs done by Scorpa and GAS GAS, they have clearly done a better job of making their electrics water (and idiot) proof.
I'll try to get a video up showing its performance. I think its pretty compelling using electrics for practice bikes. It will wheely up any hill very easily. Before I converted it, I rode it for a day and was reminded how incredibly hard it is to modulate the clutch throttle and brakes simultaneously. The electric is very easy in this regard.
