While cargo e-trikes definitely are a greener, cheaper-to-maintain alternative to delivery vans, their layout is limited by having to accommodate a chain-drive drivetrain. The Yakbike takes a different approach, as its drivetrain is electronic.
I’m curious to know if these electric only systems would still work without power or if pedaling would still move enough electrons to provide power. If so, that would be pretty cool, but personally, yeah, I think I’ll be sticking with a chain because shit happens and things fail. Love having fallback options: If my chain breaks, my rear hub can still get me home and if I lose power I can still pedal.
