Frame

Aluminium Lite 6061, Aluminium Lite, There's aluminium, and then there's CUBE Aluminium Lite. This heat-treated 6061 aluminium is stiff, fatigue-resistant and, because of its natural corrosion resistance, a great material from which to make lightweight tube sets – and bicycle frames. And it does all this without adding unnecessary weight, so you can get the best enjoyment out of your CUBE. Not identified

Highest gear: 25.1 km/h

Total gear range 418%

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: 15.7–65.5 gear inches
