Gearing
Lower gears help on climbs. Higher gears suit higher speeds.
RPM = pedal turns per minute.
How 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.
