This value is within the central range for this class.

Cohort: Mountain / Enduro Model year: 2020
Sample: 678 bicycles with this information
Coverage: 80.6% of the class

Lowest gear

20.9 gear inches

This value is above the central range for this class.

Gearing

Estimated speeds at 80 rpm

Lowest gear: 8.0 km/h
Highest gear: 36.4 km/h

Total gear range 455%

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: 20.9–94.9 gear inches
Class reference (p10–p90): 17.3–93.5 gear inches; The band runs from p10 for the lowest gear to p90 for the highest gear.

Cohort: Mountain / Enduro Model year: 2020
Lowest gear: 705 bicycles with this information, 83.8% of the class
Highest gear: 705 bicycles with this information, 83.8% of the class
