Cool Re: How weak is Your weakest link?

The only "weak link" I've found so far is the front brakes under cargo load in hilly terrain, I'll be swapping the 160mm rotors for 203s for a touch more grip.
Yeah, I was looking into a jackshaft for this bike. When I was putting together my parts list, the jackshaft for the Huasheng was a questionable part to me. I've seen the modifications required to get some to work with a Chinese shaft. A few months later SBP came out with it.

How does your jackshaft do? On a scale of 1 - 10 where would you put it in reliability and helpfulness in pulling a load?

Looking forward to seeing more of this Hybrid tech in the future. As soon as you can charge your batteries from the motor, I'm in too. When I get further into my light system from a dynohub, I'll post some great electronics tips and some electrical theory behind self-sustained travel.
