Versatile All-Rounder for Everyday Adventure
Whether you’re gliding through city streets, riding to work, or escaping to the countryside at the weekend, the Xroad 4 Open is designed to make every journey smooth and enjoyable.
Its SR Suntour XCR 34 fork with 120mm travel and wide 27.5" Schwalbe Smart Sam tyres absorb bumps and uneven ground effortlessly, giving you confidence and control across varied terrain. The open step-through frame combines everyday convenience with the sturdiness needed for mixed-surface riding.
Powerful, Comfortable & Smart
With Bosch’s Performance Line PX motor and Smart System integration, the Xroad 4 Open delivers a natural, quiet and dynamic ride. The Purion 200 display keeps key ride data clear and simple, while the Bosch Flow app unlocks advanced features like activity tracking, over-the-air updates and the optional ConnectModule for GPS-based theft protection.
Every contact point is designed with comfort in mind — from the suspension seatpost to the ergonomic handlebar and Essenza+ Moderate saddle. Integrated lighting, mudguards and an MIK HD-compatible rear rack make it fully equipped for commuting or touring straight out of the box.
