I have been lurking for awhile reading many threads and putting together my first eBike. I tried to maximize stealth, utility and range.
Started off with a $319 donor bike from bikesdirect.com:
A few miscellaneous upgraded bike components later...
(EDIT: Most Current Images Here...)
Added one of cellman's kits. A MAC 10T, 50v 18.5Ah (14s9p) LiMNC Triangle Pack, CAv3, 12 FET 3077 Infineon Controller:
(I had a problem with the kit at first and cellman came through and I highly recommend his products.)
The rack is actually made for 29" frames and I use the extra couple of inches to hide the controller and wiring:
I encased all wires in rubber (old tube) and I used a black Radio Shack project box as a junction box to hide and protect the connectors:
The controller is mounted upside down using some hard wood supports (painted black) attached to P brackets under the rack:
I encased the battery in some yard sign material and duct tape and put some foam around the corners and pressure points. I can remove it easily with no tools to take with me in to stores or to charge at work. It can even fit in my pannier bags for extra stealth.
Drip loop and rubber cover. There's a Grin Tech rear torque arm on the other side. Nord-lock washers. I used a car tire iron to tighten.
A heavy duty double kickstand. Best investment ever. This facilitates loading and unloading of the battery and pannier bags and working on the bike. When the front is weighted, the rear wheel is off the ground and I can play with throttle settings without worrying about the bike taking off:
The tire system. Kenda K838 Slicks, Planet Bike Fenders, Extra Thick Slime Tubes, RhinoDillos Tire Liners, four spoke magnets. I hate flat tires!
The controller is mounted to the rack in a way that does not interfere with the rack or its mounting system:
With the pannier bags unfolded, the controller cannot be seen and is protected from rain etc:
Screens from my last ride (a night ride in a thunderstorm!):
I used about 3/4 of my battery for that. I only ever use about 3/4 of the capacity, I charge it to %90 and limit the draw to 30A (just under 2C) to preserve the LiMNC chemistry and battery lifecycle. This isn't a LifePO4 so no 2000W speed demon. Most of the time I cruise around using 9 amps (1/2 C)
I use the CAv3 closed loop throttle control, throttle controls total Power (W) used by the controller/motor.
I use a three position switch to set the limit of maximum power to 500W, 1000W and 1500W max.
