Came home to my charger and 54lbs of batteries on my doorstep. It's about to get very real in the next few days. The 100amp controller itself weighs like 3lbs. Stay tuned while I wire it up and do some trial runs.

Hooked up two 8ah 36v pks in parallel for 16ah. The Batts are mismatched and 5yrs old but each pack pulled me on a razor e300 to the bar and home. A few times. So I did a field test. Bike could not pull me. Motor hummed like a hornets nest. Lifting the tire I got a zippy responce. I even dropped...

Drilled 2 mount holes and locked in the motor. Frakenstiened a roller from 2 sources and bolted it in. Chain is a bit floppy and the motor could be remounted an inch over but the chain path looks straight enough and I could use to over the original mountholes so it should be straight enough...

Motor is rated at 1/3 hp but I'll be running double voltage with a yk43b controller it runs24-60v 100amp peak. Motor peaks at 40 amp and runs 18amp constant. I'll be pushing it hard but it's meant to run all day

No need for a clutch just instant power....unless you start at the bottom of a hill. Then you're just burning amps and over heating the motor. This industrial motor should tackle hills with ease. My 60v dirtbike would climb just fine but lose 5mph that was also on pavement. I can't wait to...

This is an old build with dual 24v motors and 60v of 8amp hour batteries. 10lbs worth of motor 30lbs of batteries. 0-20mph in seconds. https://youtu.be/mGtEUMxbywI Starting tweaking kid toys years ago for the neighborhood gang and my own fun. https://youtu.be/qTinsrIJbYg...

After some research and ebay scouring I chose a 24v leeson at 1800rpm. Gearing 20/70 with 8 in tires I think I can get a good balance of grunt and top end speed. Running at 48v it can hit 3600rpm 24mph. I got the motor sprocket from surplus center. 5/8" shaft with keyway. Should sound familiar...

The frame around has the body corners cut out. I priced a 6.5hp and belt drive for under $250 with chain. Most doodle builds claim they can climb daunting hills with this setup. A big plus for me, but I want to ride at night. I have a nice firepit in my lower field. It'd be nice to shuttle to...

The frame needed some work out of the chute. Missing brake pad wheel bearing chain roller and chain guard. After buying parts I found the brake housing was missing the spring clip that keeps the pads spaced. The wheel bearing was blown out and the collar was stuck in the hub. I ended up clipping...
