ABS Cargo

Cargo bikes place huge demands on the brake system. The Bosch eBike ABS provides faster, safer, and more accurate braking, even when fully loaded. This protects you, your load and other road users.

Smart walk assist

When you need to get off and push, Cargo Line Walk Assist eases the burden. Press and hold the minus button to activate. As soon as you start to push your Cargo bike, motor support kicks in. At the same time, the integrated Hill Hold function stops your bike from rolling backwards or downhill. Safety is never an issue, even on the steepest of climbs and setting off on your bike again is effortless.

Easy handling

Save battery power and increase your range: When you cycle faster than 20 mph, the electric motor and gearbox automatically decouple. This results in minimal pedal resistance and exceptionally smooth handling. Cargo Line is also compatible with shorter pedal cranks. This means better ground clearance and an even safer ride.

Effective technology

Keep your eBike cool, no matter how hard it's working. When pushed to perform, or on hot days, the cooling fins of the Cargo Line keep the heat at bay. With no need to worry about the drive unit overheating, you can push yourself to the limit, even on long summer rides. Cargo Line's compact dimensions and magnesium housing reduce the weight of the drive unit to just 6.4 lbs. This makes your eBike even lighter and easier to handle.

Individual riding modes

You can fine-tune the riding modes of the smart system so that they offer you more support or enable longer range.
