I am planning to build a ebike this summer. I was hope to use my existing road bike and add a dc brushed motor behind the seat and above the wheel. It will be a chain driven and not friction bike.
But the real question is i was planning on buying from electricmotorsports.com
and this controllerhttp://www.electricmotorsport.com/st...ltrax_4834.php
Has anyone here had any problems with electricmotorsports? Or of the motor/controller?
Any good things to report, i searched around here and a few other websites but oddly there isnt any reviews.
Second, are there any smaller brushed dc motors out there since i wont really need 4kw but am finding a hard time finding some.
30mph with 140 lbs rider
better acceleration than when pedaling (but without the assistance)
