Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.

Estimated speed at 90 RPMGear
Rear tire: 12×1.75.
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.
