Thanks for the interest born loser, the electric minibike started as a way to let my 12 year old son ride around the neighborhood without bothering the neighbors (where I live in California the local authorities and the neighbors have limited patience with loud minibikes). Anyway, due to my hot rod upbringing I naturally over engineered the project and shoehorned a power combo consisting of a Briggs and Stratton Etek motor, an Alltrax controller, 4 x 20ah B&B batteries, all linked up with 6awg wire. The system produces 15,000 watts, 19 horse peak/10 horse constant with three times the torque of an ice, luckily the Alltrax controller (blue) that sits on the battery box is fully programmable which allowed me to tame the beast down so that my son could ride safely.
The minibike runs two 100w converters that power the two 55w spider eye headlights, an LED Maltese cross tail light and some purple glow treatment because why not, it is a blast to ride at night.
The aluminum number plates cover up the motor and keep fingers safely away from the drive gear, terminals, main fuse, shunt, and solenoid, (there’s lots of stuff under there that will shock the shit out of you).
The system has only one moving part which is the drive gear twisting the rear wheel. There are no fluids, no intake, no exhaust, no tune-ups, no warm-up, no pull start, no vibration, and no noise.
I have a trick 6.5 clone in another Azusa frame and although it is fun to ride, it can't compare to the advantages and performance of the electric.
Now the downside, the runtime is about 10 miles max, it takes 6 hours to recharge, the batteries are 80 bucks each and you need four of them, they can be recharged about 400 times before you need a new rack, and finally, the cost to build it was about $2500 so it wasn't cheap... But it was worth it and I'm currently building another one. :biggrin:
