LocationAlbuquerque, New Mexico US map
Vehicle2005 Roadmaster Mt. Fury
Cheapo Wal-Mart special that I bought to get me home after my truck broke down
MotorUnite Motor My1020 36volt, 750 watt, 28 amps max Brushless DC
Mounted motor to aluminum plate, which mounts to front fork. Does not seem to affect handling in any way
DrivetrainMounted threaded mountain bike wheel to front, added scooter freewheel and sprocket. 80/11 ratio, seems just right
ControllerYi Yun YK42-3
Uses 20 amp house plug to connect to batteries
Batteries6, 12.00 Volt, Lead-Acid, AGM
I am recycling old UPS batteries. Box is quite heavy for only 14ah, so I plan to change to 3 power sonic 21ah cells soon and move them towards the center for better handling
System Voltage36 Volts
ChargerYi Yun
Heatermetabolism
DC/DC Converter None
InstrumentationSchwinn odometer/speedometer
Top Speed41 MPH (65 KPH)
41, full charge, downhill, while pedaling. Brakes started smoking and smelled bad. Average speed on a flat without pedaling is 28MPH, and can do 20 uphill, but motor gets HOT
AccelerationExcellent, even better with pedaling
Range15 Miles (24 Kilometers)
Should be 15 miles, but with the old cells in the pack, I start to see performance loss at 5.
EV Miles
Current:22 Miles (35 Kilometers)

Seating Capacity1 adult
Curb Weight0
Not too bad, just awkward in the back because of location and height of batteries.
Conversion CostLess than 300, but I got some of the batteries for free
Having less weight in the front, it takes time to gain traction under full throttle. I never thought it would be so much fun peeling out on a bicycle. Gotta love that smell.
