24

4.5 Brake modes On the knob to the right, you can put the bike into 3 di erent braking modes. This ranges from a freewheel experience, much of what you feel on an MTB, which is suited for mellow riding on flats, to a hard engine brake, that is similar to the engine brake on a 4-stroke motorcycle, which is suited for technical riding. All the energy from the braking goes back into the battery for extended range.
Brake mode 1 Freewheel, no motor brake. Gives the same sensation as riding a bike, perfect for mellow riding and the ultimate freedom experience.
Brake mode 2 Intermediate motor brake with energy regeneration. As you release the throttle you feel the bike slowing down at a slow pace. This can boost your confidence when riding a bit more technical terrain as you get better control over the bike. The braking power is regenerated to the battery for extra range.
Brake mode 3 Hard motor brake with energy regeneration. When releasing the throttle, the bike will slow down significantly. This could be uncomfortable for novice riders as the braking is quite hard. This brake mode is best suited for technical tracks where full control for the bike is needed. All the braking power is regenerated back to charge the battery for extended range.
WARNING! Risk of personal injury. When slowing down using the motor brake, other road users are not notified of your slowing down. Use the motor brake with caution. Always use the mechanical brakes to bring the vehicle to a standstill.
