Vehicle
Still looking for a donor vehicle for the wheels & suspension. The front wheel & suspension of a full-size motorcycle stack up too high for good visibility with a low rider position so I'm looking into scooters and subscale motorcycles
MotorPerm Motor PMG-132 Permanent Magnet DC
DrivetrainPreferably a belt, but a chain will do, and the width is in a critical spot.
ControllerAlltrax AXE 4865
650 Amp, 24-48 V
Batteries160, 48.00 Volt, Lithium-Ion
16s10p 2.2Ahr, 3.6V cells from disassembled DeWalt 36V batteries, unless I can get the cells directly from them. I'll probably have a separate 12v Li-Ion battery for accessories so I can distribute the battery weight and avoid a DC/DC converter.
System Voltage48 Volts
ChargerSoneil 48V
Heaterprobably just garage pre-heat
Instrumentationreal-time bar graphs of each cell voltage, combined with overvoltage protection and cell balancing. Design done and prototype parts on order...
Top Speed85 MPH (136 KPH)
Accelerationprojected, 0 to 60 MPH in 6.5 Seconds. Using series/parallel dual ETEKs is tempting
Range48 Miles (77 Kilometers)
projected, Assuming 20 Ahrs of batteries, which is all I would need for my commute. There's room for more, though.
Watt Hours/Mile30 Wh/Mile
projected, The plan is to use a fully enclosed fairing to make this the world's most energy efficient commuter vehicle. The world's fastest human powered vehicle (varna diablo) has achieved 80 mph on about 450 watts using a very compact aerodynamic fairing. I'm shooting for about 1600 battery output watts at that speed.
Seating Capacity1 adult
Curb Weight230 Pounds (104 Kilograms)
Motor, batteries and controller will be about 70. Hoping for about 160 lbs for the rest.
Conversion Timeprobably 300 hrs planning in the last 5 months so far. Still to go: about 1.5-2 years of evenings and weekends
Conversion Costestimating about $10k
Additional FeaturesF1-style composite safety cell for the rider.
5-poit racing harness
21" step-over sill to get in. Spring-loaded doors for feet. Winglets enclose the rear view mirrors, headlights, and turn signals.

30 battery output Whrs/mi converts to 380 miles per gallon of power plant fuel!
