**Small Geared hub motors speeds (RPM)**

Voltage is 36 volts, wheel is 26”/700c unless otherwise indicated
**Q100 Measured no load speeds.**- 201rpm = 18 mph
- 260rpm = 23 mph (calculated)
- 300rpm = 28 mph (201rpm 24v Q100 run @36v)
- 328rpm = 29 mph

Road speeds tend to be about 85% of no load speeds on this motor (assuming it has the power required to get to that speed)

**Q100 measured road speeds**- 201rpm = 15.5 mph
- 260rpm = 20 mph (source: ES: D8Veh)
- 300rpm = 23 mph (201rpm 24v Q100 run @36v) (rider assisted)
- 328rpm = 25 mph (dual motor or rider assisted)

*Background

The 328 motor doesn't really have the power to do much over 20mph on its own without some type of assist. If run over 20mph, the controller, pulling maximum current and generates excess heat from this inefficiency. If put in a bag it will eventually overheat and fail. (I've run for years with the controller in open air with no problems).

I pedal at 24-26mph on a 328rpm on a road bike with 200-300 watts input from my legs.

Dave at ES has posted similar numbers, his road speeds are reported at:

328rpm = 25mph (two motors)

260rpm = 20mph

201rpm = 15mph

**Q100 at 48V estimates** (overvolting the 36v motor)

- 36v-201rpm @ 48v-266rpm = 20mph (sweet spot for Q100)
- 36v-260rpm @ 48V-345rpm = 26.4mph (pushing the envelope!)
