Use voltage to get the speed back. if 100v isn't fast enough, grab a high fet count 4115 controller, mod it out and run it at 30s. Check out zombiess work.
30S on my magic pie in a 20" wheel ROCKED. And that's less than half the motor that the cromotor is...
A cromotor in a 14" wheel on super high voltage ( 30S-32S or maybe even higher ) would have you at the top of pike's peak next year, in awe of the beauty of the rockies around you.. wondering if there are any steeper climbs out there on this planet because what you just scaled seemed too easy
My first major build:
8T MAC motor on a Trek 4500.The new all-arounder:
Leafmotor 1500w on a Turner O2 full suspension.The wheelie machine:
20" Rear Magic Pie II on a Trek 4300 MTBThe Bus:
??? on a 'da bomb' cargo bike frame
Pro-tips for noobs: Charge RC Lipos to 4.15v, stop discharging at 3.5-3.6v
