Oh Wiseguy huh? ya I heard they found the 2-t pipe in a old couch at the Goodwil store. it was for a fifty but happened to bolt right up. they learned that trick in there Kart racing days that never happened.
The battery is local from http://www.rce.com.tw/ and it was a bit over 200 USD. The shop had NO IDEA how to explain the broken parts or what they were called in English. I just googled "Sprag Clutch" and sure enough, that is what it is. Mine was.....um.....how to put this......non functional is the nicest way. When I tried to start the bike it would make a strange grinding noise and not start. Also I recently put a Diablo on the back and an Angel on the front. They don't make a Diablo for the front size. Other than that, all I have done is put KMs on it and fuel in it.
My plan for rear tire/hub motor which will result in an increase from 12" rim to 14" rim to which I plan on installing a 160/60-14 Pirelli tire. The difference in size is striking which you can see from the two photos.
Well yeh on a load circuit you get what is needed, larger voltages will increase power. That would be similar to the starter circuit on a "normal" vehicle using heavy wires between the battery and the starter. I was referring to your complaint about running 72 volts to the handlebars instead of a relay setup on what I assume would be a control circuit. Engineers do that because they want to and its not just the Chinese.
Yes. When completed, this bike should be both quicker accelerating and higher top speed than my current 150cc Zuma clone. But with shorter range (using current battery technology). Will likely be able to achieve 120 mile range in a few years with new battery tech. But for now 60 mile range will be more than enough for my needs. P.S. yeah, the numerous fanny wiggles and other funnies are starting to get a bit old to me too...
