Gearing
Lower gears help on climbs. Higher gears suit higher speeds.
RPM = pedal turns per minute.
Speed unavailable: wheel or tire size is missing or unclear.
Add your rear tire size to calculate speedHow it works
Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.
Speeds are estimates from tire size and pedal cadence. Actual speeds vary.

Your changes apply to this calculation. The archived build stays unchanged.
