Sample: 2,036 bicycles with this information
Coverage: 96.6% of the class

Lowest gear

18.2 gear inches

This value is within the central range for this class.

Cohort: Mountain / Trail Model year: 2024
Sample: 1,558 bicycles with this information
Coverage: 73.9% of the class

Highest gear

84.4 gear inches

This value is below the central range for this class.

Cohort: Mountain / Trail Model year: 2024

Gearing

Estimated speeds at 80 rpm

Lowest gear: 7.0 km/h
Highest gear: 32.3 km/h

Total gear range 464%

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: 18.2–84.4 gear inches
Class reference (p10–p90): 17.1–98.6 gear inches; The band runs from p10 for the lowest gear to p90 for the highest gear.

Cohort: Mountain / Trail Model year: 2024
Lowest gear: 1558 bicycles with this information, 73.9% of the class
Highest gear: 1558 bicycles with this information, 73.9% of the class
