Gearing

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

RPM

RPM = pedal turns per minute.

Estimated speed At 90 RPM Lowest gear6.7 mph Highest gear29.0 mph

Uses front tire 20×1.95; rear size isn’t listed.

How it works

Ratio = chainring teeth ÷ rear sprocket teeth. A 400% range means the highest ratio is four times the lowest.

Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
