|Owner's Other EV||2007 Schwinn Trailway|
|Location||Dallas, Texas US map|
|Vehicle||2004 Kona Stinky Downhiller|
|Motor||Crystalyte 408/4012 dual wound Brushless DC|
Dual wound Crystalyte motor, Direct drive hub. Modified for disc brake
72 volt, 40 amp using 4110 MOSFETs
|Batteries||8 5 cell 5 amp RC batteries, 18.50 Volt, Lithium-Polymer|
Lithium Cobalt RC batteries. 92 watts and 1.4 pounds each. Each battery is rated at 20c normal, 30c burst. I generaly run 4 in series unless I need more range.
|System Voltage||74 Volts|
|Charger||Imax, and generic|
|Heater||Warm thoughts and thick gloves.|
|Instrumentation||Cycle Analyst from Ebikes.ca|
|Top Speed||40 MPH (64 KPH)|
|Acceleration||it will hit 30mph in 100 yards or less. but being a hub motor, it feels sluggish taking off from a dead stop to about 10mph|
|Range||10 Miles (16 Kilometers)|
It will go 10 miles if driven like a rental. 50 if ridden at bicycle speeds. I usually get in the middle of that
|Watt Hours/Mile||15 Wh/Mile |
15 Watts per mile is the best no pedal I can get in normal stop and go riding. But I prefer a more aggressive style that leads to 30Watts per mile.
With modest pedaling, 11w/m is easy enough.
|Seating Capacity||1 adult|
|Curb Weight||80 Pounds (36 Kilograms)|
|Tires||Maxxis Hookworms. 26" X 2.5"|
|Conversion Cost||Oh Hell...|
|I'm running it at 3000 watts, 4 horsepower peak. It will outrun mopeds and small motorbikes. |
It was my second Ebike build. I'm now on my 6th but I still have this one. It just works too well to get rid of.
