Design details

Power

Battery range: 35 km in economy mode / 25 km in normal mode / 20 km in sport mode (illustrative information that may vary depending on the tyre pressure, terrain, conditions, and weight of the rider). The correct tyre pressure is 4.5 BAR.

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.

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%)

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.

Drivetrain

6 speeds with Shimano grip shifter. Shimano Tourney 6-speed rear derailleur. 52-teeth chainring.

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.

Handlebar / stem / steering

Fold-down, height-adjustable aluminium stem for added comfort. Quick release with automatic safety lever Semi-raised aluminium handlebar.

Saddle/Seat post

Anti-theft, anti-rotation aluminium seat post 34mm in diameter. The graduation on the seat post makes it easy to adjust.

Tyres / wheels

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.

Accessories/Equipment

Battery-powered front and rear lights with handlebar control. Bike equipped with kickstand and mudguard.

Compatibility

The bike is compatible with: - the B'TWIN folding bike pannier rack (ref. 8328464) You may need to remove the magnet from the rear axle to easily install the pannier rack. The magnet can be returned to its position once the pannier rack is installed. - TILT transport cover (ref. 8271631) - Hamax child trailers (ref. 8607793, 866501) and Bike Original trailers (ref. 8597302) The TILT 500 E is NOT COMPATIBLE with a child bike seat.

Storage and battery care advice

VERY IMPORTANT: This battery doesn't have a "deep sleep" mode. If you're not going to be using your bike for an extended period, you must charge it every 3 months to stop it going into a deep discharge state and becoming completely unusable. Before performing any work on your electric bike (cleaning, electrical or mechanical maintenance), you must turn off your electric bike and remove the battery.

Care tips

Tyres lose pressure over time. On average, they lose 1 bar/week. So remember to regularly pump up your tyres. Riding with under-inflated tyres reduces your battery range, requires more pedalling effort, and increases the risk of punctures. Before performing any work on your electric bike (cleaning, electrical or mechanical maintenance), you must turn off your bike and remove the battery. If you aren't going to be using it over winter, charge the battery at least every 3 months.
