Specs
Build
Frame

Aluminium frame with built-in battery. The battery can be charged directly through the frame or removed from its spot to be recharged at home, work, etc. A quick locking system at the frame can keep the bike folded and make it easier to transport. No locking system at the stem. The wheels on this bike do not turn when the bike is folded.

Fork

Steel fork.

Groupset
Brakes

Aluminium V-Brake callipers for powerful, progressive braking. Aluminium levers with rubber pads for added comfort. Braking cuts out electric assistance. Remember: The brake pads on electrically-assisted bikes wear down more quickly than a classic bike due to the weight and power of the motor.

TypeRim

Wheels
Tires

Size 20 x 1.75. Tyres with anti-puncture reinforcement. We've developed these tyres using Skinwall technology for lower weight and higher performance. We recommend inflating your tyres to a pressure of 4.5 BAR for optimal performance, better autonomy and to reduce the risk of puncture. Double-walled rims for greater rigidity. Motor built into the rear wheel for improved steering control.

Electric Components
Motor

250W brushless motor on the rear wheel. Electrical assistance generated by the pedalling sensor. Motor torque: 26 Nm, ideal for slight inclines (e.g. bridge climb ≈ 3%)

Battery

The 187 Wh (24 V / 7.8 Ah) battery at the frame cannot be locked. But it is easily transportable. Battery and charger supplied with the bikeLifespan: 500 full charge cycles (1 cycle = charging from 0 to 100%). Beyond these 500 charge cycles, the battery still functions but not to its full, initial capacity. Its capacity can drop by up to 20%. Warranty: 2 years.
