Re: Newbe that's looking for quick advice on possible build.
Hi Dragon, I am in Phoenix (Sunnyslope).
I am not fan of any motor mounted over a wheel but certainly an option if there is no room for a motor in the cavity.
Then again for about the same $ you can mount an electric in there and it will even use your bike's chain drive and gears, I just built one, very cool.
Stop by my web site with forum and register up, it all depends on the bike and your budget but like here you can upload your bike pics and talk to us locals about it.
