Technical analysis

1 measure

How these figures sit among bicycles of the same class and model year. Context, not a ranking.

Weight

34.8 kg

This value is within the central range for this class.

Cohort: Urban / Utility Model year: 2021
Sample: 32 bicycles with this information
Coverage: 91.4% of the class

Gearing

Estimated speeds at 80 rpm

Lowest gear: 11.4 km/h
Highest gear: 35.2 km/h

Total gear range 309%

Technical details and class reference

These speeds describe the gearing at the selected cadence, not how fast you can ride.
Calculated from published gear-inch values and their wheel-size assumptions.
These gearing values describe the bicycle, not a selected frame size.
A 100% range means one ratio; 500% means the highest ratio is five times the lowest.
For e-bikes, motor assistance cutoff is not represented.

Gear-inch range

Lower gear-inch values travel less distance per pedal revolution; higher values travel farther.

This bicycle: 29.8–92.0 gear inches
