Technical analysis

1 measure

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

Weight

12.53 kg

This value is above the central range for this class.

Cohort: BMX Model year: 2019
Sample: 60 bicycles with this information
Coverage: 83.3% of the class

Gearing

Estimated speeds at 80 rpm

Lowest gear: 13.7 km/h
Highest gear: 13.7 km/h

Total gear range 100%

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: 35.7–35.7 gear inches
