Hey Guys,
I was in the shop the other day after finishing a bunch of work on customer's bikes and drive systems and I began looking at various parts I had laying around the shop. "Hmm, I have a drawer full of lipo packs (brand new). I have a couple battery boxes, a brand new fan cooled 5 turn Delta 3220, controllers, throttles, drive parts, frame mounts, sprockets, chains, etc. Then I glanced at my red Hooligan that I had setup for mild trials riding [but rarely ride] and I decided to build myself a bike as quickly as possible and this is what I came up with.
Here are the specs;
V4 drive
5 turn Delta, fan cooled 3220 (12,000 RPM motor)
10ah of 12S-25C lipo in CNC machined battery boxes
Drive unit frame mount clamps used to mount the boxes
Edge 160 controller
Simple PWM throttle
18 to 1 ratio from motor to rear wheel
One of my 47mm wide rims on the rear
AUW is 45 pounds exactly
I set to building the bike, and all of the wiring, component mounting, machining a couple small parts, I had spent 4 hours on the bike and it is finished. I have around 15 miles on it so far. The range is around 10 miles on a charge with my wheelie riding style.
So, I programmed the controller for throttle response setting of 1. This reduced the violence of the response and drastically smoothed out the low speed control.
The bike rides great and is EXPLOSIVE! I have pulled nearly 10,000 watts according to the data logger. I can run at 30mph and snap wheelie violently. It is actually way too much power for such a small bike. But, with the throttle response at 1 and a bit of care taken with the throttle, it rides wonderfully.
This bike is very similar to the PK Ripper I built 5 years ago, but it is lighter, faster, and more refined.
I cannot believe how easy this bike was to build.
Enjoy the pics.
