When motor assist and human leg power meet, the range of terrain a bike can conquer grows almost exponentially. The H 1900 SPLINE are designed for that. We have given them the reliability of Swiss precison hubs, tough spokes and a strong, yet lightweight rim to head out into unknown rides, just to see how far this new man / machine system can go. But you needn't worry: Like all of our products, passionate employees have tested the H 1900 SPLINE to their limits in the notoriously rough and steep Jura mountains. To prove their reliability so you don't have to, for that and because it's a whole lot of fun.
