Riese & Müller UBN Five has three different gearing options; the touring' has an 11-speed Shimano Deore gearing system, the'silent' an 8-speed Shimano Alfine internal gear hub, and for the first time on any Riese & Müller eBike, a 'singlespeed. What is your experience with riding or owning this new eBike. Which gearing option did you choose. I’m currently riding a Specialized Turbo Vado SL 4.0 for the past 2 years and looking at a possible future replacement. Specialized warranty service has been fantastic so far so wondering how your experience has been with Riese & Müller.
