Though I have searched, there seems to be no relative topic. Hope to find more info, but if people are willing to point me in the right direction maybe it will save some time.
I have access to a MTB frame that I would like to electrify, but from what I have gathered so far a direct drive hub motor make enough noise to prevent "stalking". Solution, geared hub motor on the front.
So how complex would, or even can be, to fit this on 1 frame?
Part of the reasoning it to not stick out w/ large hubs in an urban setting. The direct dive size off set by the gear assembly.
Would it be practical to build a controller that uses the front gear hub for start up as well as hunt mode. Then in the 10-15 mph range, the rear direct drive would kick in and even take over @ urban cruise speed (about 30mph). I don't expect to be traveling 40mph, but @ 300 lbs would like the extra torque as well as keeping the eff up at cruise speed.
How effective would capacitors be at recovering regen brake current, and how would it be returned to the system.
Just throwing this out, will have to search for the applications I hope to apply.
