Versatile Riding Versatility. A mountain bike is designed to ride up and down mountains and to provide fun while doing so. The H 1700 SPLINE does precisely that. And since e-bikes allow the rider to go up and down many mountains in one ride, reliability and lightness is key. With our expertise in bicycle components and demanding testing procedures, we are able to design and spec a wheelset perfectly suited to its intended use. This is exactly we did with this wheel, leaving the pedaling up and down mountains to you.
