E-Gravelbikes tested: Perfect for the commute

There 's a good reason why gravel bikes remain so popular. They're the perfect all-rounder: comfortable in the city, safe on country roads. Commuter bikes could actually be described in exactly the same way. Often with an electric motor and full equipment, they can be used in rainy weather and at night. Nevertheless, there's been little overlap between these two categories so far; gravel bikes are primarily in the sporty segment. Voila, may we introduce: the UBN series from Riese & Müller. The three letters of the model name stand for "Urban," meaning use in the city. The e-bike is available in several versions: with racing bike or straight handlebars, with derailleur or hub gears, the latter with stepless gears on request.
