Technical analysis

2 measures

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

Front travel

63 mm

This value is within the central range for this class.

Cohort: Urban / Hybrid Model year: 2026
Sample: 580 bicycles with this information
Coverage: 72.4% of the class

Shifting

Mechanical

21 of 801 bicycles with this information use electronic shifting.

Cohort: Urban / Hybrid Model year: 2026
Sample: 801 bicycles with this information
Coverage: 100.0% of the class

Gearing

Estimated speeds at 80 rpm

Lowest gear: 7.8 km/h
Highest gear: 40.0 km/h

Total gear range 510%

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: 20.5–104.4 gear inches
