At 14.1 kg, Curt is more than 30% lighter than the average electric bike, making it easy to lift and carry. The lightweight componentry and smart frame design make Curt one of the most lively urban e-bikes around, ready to take on the streets straight out of the box.
The bike’s torque sensor constantly measures how hard you pedal and calculates the level of assist for the electric motor. The motor provides more assist the harder you pedal, and less assist the lighter you pedal. This puts you always in control of the bike and keeps your ride safe.
The average battery assisted range is 70 km, giving you peace of mind on all your rides. And even if you run out of juice, you simply keep on cycling. One hour of charging will give you 33 km of range, and it takes just 2.5 hours for a full charge.
You can ride the bike perfectly even without a smartphone. However, the app lets you:

The battery is integrated into the down-tube of the frame. The frame and the battery are designed in such a way that every professional bike shop could remove the battery, and if needed, replace it with a new one in under one hour.
The battery is charged with the charger, which comes with the bike. The process is similar to charging your laptop – you have to connect the bike with a standard wall power outlet.
You can use our mobile app to:
You can get the free Ampler Bikes app from Play Store (Android) and App Store (iOS). You can also change all the standard functions from the Power Button on your bike.
You can find your perfect frame size based on your height:
160 - 170 cm = Small frame
170 - 185 cm = Medium frame
185 - 200 cm (and above) = Large frame
The geometry of the bike is made according to the most ergonomic and optimal seating position.
If your height is right in the middle of two frame sizes (e.g. 185 cm) we recommend you taking the smaller frame.
