To keep you visible in the dark, Curt comes with bright Busch+Müller front lights and LightSKIN LED rear lights integrated into the seat post.
Curt has Shimano hydraulic disc brakes that are designed for high braking power, reliability and easy maintenance. This makes your ride in the fast city traffic safe.
Curt is equipped with lightweight Continental puncture-protected tyres so you’ll never have to worry about getting a flat tyre from sharp stones or broken bottles on the streets.
You have a window into your bike via Ampler mobile app, where you can customise the motor assist settings, track your rides, navigate with built-in maps, and receive over-the-air updates.
