When motor assistance and leg power meet, the range of terrain a bike can conquer grows almost exponentially. The H 1900 SPLINE is designed for this, now upgraded with the famous DT Swiss Ratchet technology. The Ratchet LN system distributes the combined forces from the rider and the motor over a larger area than the previous pawl freehub systems, increasing the systems' durability thanks to lower load peaks. The 370 hub enables full power transmission to the ground with reinforced hybrid spokes laced to a resistant aluminum rim, available in two inner widths. Aluminum rim, Hooked / Crotchet tubeless ready DT Hybrid 1 spokes are reinforced and increase the lateral and torsional stiffness of the wheel 370 Hub Specifications ColorBlackDefined ColorBlackDesigned for ebikeYesFront Axle15mm Thru x 110mmHub/Brake Compatibility6-Bolt DiscISO Diameter584 / 650b / 27.5"keyword searchhybridkeyword searchelectric bikes, electric bicycle, e-bike, e-bikesRim MaterialAlloyRim Width (Internal)30Tire TypeTubeless Ready ClincherValvePrestaWheel Size27.5"
