Re: Question for jackshaft guys?
I just put a shift kit on a bike for a guy that has a 3 speed Nexus hub. First gear is so low that he can take off from a dead stop without having to pedal first and he's a big guy. I drove it across a very thick matted grassy lawn and started in first without pedaling. Barely any strain on the clutch. Off roading wouldn't be a problem I'm sure.
I'm putting a shift kit on a 7 speed derailer right now. I'll be curious to see if all those extra gears are really worth it. The 3 speed hub seemed to cover all the needs that a shift kit allows.
