Dug up from a old post is my 'pushy pusher', it looks a little different now & soon to have, better storage & a new Infineon controller, as I am RPM limited @ the moment due to the banfang being a geared motor & not liking the basic controller...banfang is light & small & seems to last in a 16" wheel without striping out the plastic gears... old post below...
Built up a 24v /26" banfang into the rear of my BOB trailer...running from a 18A (modded for 48v) controller, powered by 9Ahr 48v LiFe pack, on my Surly Karate Monkey 29er. Custom cruze control & dynamo driven LED lighting system
Bike fully built (even wheels) by me, running solid rear axle & bob nutz.
to the left of the gear numbers is the 'GO' button
& the magnetic brake reset (which cuts the cruze control throttle button when braking)
Very basic cruze control using 1/ 5v relay & a feed back loop (latch link), I added a dropper diode just in case my controller did not like the full 5v, so now it sees 4.3v on throttle signal input. The controller is modded with a 12v zener reverse bias to the LM317 (PCB reg) so it still sees 36v + a few caps were changed. Extra heatsink added to controller box just in case.
Custom lighting system by me, driven from dynamo hub, with circuit to give 12.4w rather than 3w, in to cree R2 bin LEDs we get 750lm output (HID lights ~450lm)
Also to let people see how easy the martin basic circuit really is, I have re-drawn it, with a pic of what the parts look like the way I build it (dead bug style)...each step is the same circuit, just re-drawn so its easier on the brain...
as its a 26" hub in a 16" wheel, it goes up any hill I throw @ it... top speed up a hill 27 km/hr & 29km/hr on the flat...
