Whether it’s your daily commute or a tour with luggage: the DT Swiss HU 1900 SPLINE is designed for heavy loads in everyday e-bike use. With a maximum system weight of 180 kg and a 35 mm-wide aluminum rim, this 27.5" rear wheel provides a foundation for wide tires and comfortable rolling.

The 370 hub with Ratchet LN 18 transfers your pedaling power through a ratchet system. 12x148 mm Boost, Center Lock and the Shimano HG freehub determine which interfaces are compatible with your bike. The installed tubeless rim tape makes setup easier; a compatible tubeless valve is required separately.
