Technical analysis

1 measure

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

Shifting

Mechanical

9 of 321 bicycles with this information use electronic shifting.

Cohort: Youth / Mountain youth Model year: 2026
Sample: 321 bicycles with this information
Coverage: 100.0% of the class

Gearing

Estimated speeds at 80 rpm

Lowest gear: 5.5 km/h
Highest gear: 19.5 km/h

Total gear range 355%

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: 14.4–50.9 gear inches
