My knees are knackered, so my objective is to put together an e-bike for electric-only usage. Hence, I need to know which front hub motors are suitable for reliable standing starts. Pedaling up to some speed before the motor kicks in is not an option for me.
FWIW, the jurisdiction I live in allows for up to 500W motors, so that allows me more flexibility than some countries.
Some time ago when I first looked into this I found a web site that compared many different models and brands of motors for suitability of standing start vs pedaling start (minimum bike speed>0 before motor takes over). I wish I bookmarked it; now I can't find that site. Anyone know of it?
Alternatively, is there a relatively reliable number for minimum torque required to allow consistent standing starts?
If it matters, the target is a 26" wheel, mixed-use frame (not racing, not mountain bike - I guess "comfort" or commuter bike would be the term).
