Optionally with backpedal brake

If you opt for an eBike with hub gear system, you have the option of selecting a backpedal brake with the Active Line Plus. It gives you a safer feeling and increased comfort when braking because you can, for example, give hand signals and brake at the same time.

Robust and reliable

The single-stage gearbox of the Active Line is designed for extra durability and robustness, so you don't have to worry about the weather conditions or dirt. Use your eBike every day and enjoy many years of riding fun - that's what the Active Line was developed for.

Additional safety: ABS Touring

Uneven road surfaces, zebra crossings and traffic lights are part and parcel of every trip. Whether you're commuting to work, or taking some time out from the city traffic in nature at the weekend, you need brakes you can rely on. ABS Touring gives you the certainty of being able to brake in a controlled manner at all times.
