Does that motor use the bicycle's gears? I would think it would, but I can't really tell if they are only for pedalling or if the motor uses them too.
If that uses the bike's gears though, it would be perfect if it had enough power to move a heavier guy like me (220 pounds). Based on what I have been reading here, I think I need at least 500 watts (or more) and 36 volts (or more).
It's good to know that these things do exist though. Maybe there is one out there that has the power requirements...
It does not. It has gears of its own that you can use as the cyclist, but the motor itself is a single speed geared unit. The Sparc is also a low power unit, its a system thats geared towards the cyclist crowd rather than the e-biker, so its built around helping out with headwinds and hills rather than powering you around on its own.
As for the 500w thing, thats entirely subjective to the motor being used.
