- Data limitation
No geometry is recorded for 2010 Jamis Beatnik and 2014 Jamis Beatnik.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.
Ratio2.88:1
Estimated speed at 90 RPMGear
Uses front tire 700C×25; rear size isn’t listed.
Ratio2.88:1
Speed unavailable: wheel or tire size is missing or unclear.
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.
