Key differences
Supported differences are shown below. Data limitations are labeled separately.
No key difference could be established from the available data. Check the full table for the details.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.
Ratio2.69:1
Estimated speed at 90 RPMGear
Rear tire: 20×2.
Ratio2.75:1
Estimated speed at 90 RPMGear
Uses front tire 20×2.125; rear size isn’t listed.
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.

Historical specifications are presented as an archival reference. Components may have varied by market, size, or production run. Legacy reference geometry is model-level historical data whose corresponding frame size is not identified; compare those dimensions as reference values rather than size-normalized fit data.
