Moustache Bikes Xroad 4 2027 - 600 Wh

The Moustache Xroad 4 2027 is a versatile electric bike built for riders who split their time between city streets and unpaved tracks. Its step-through aluminium 6061 frame keeps access easy for a wide range of riders, while the hydroformed triple-cavity tubing integrates the Bosch PowerTube 600 Wh battery cleanly within the frame, keeping the bike balanced and the lines tidy.

The Bosch Performance Line PX BDU34 motor (90 Nm) pairs with a 10-speed Shimano CUES drivetrain (11-43 cassette, 38T Narrow Wide chainring) to give you a wide gear range for loaded climbs or brisk road stretches. Assistance is managed through the Bosch Purion 200 Smart System handlebar remote, which keeps the cockpit uncluttered.

Ride comfort is handled by a SR Suntour XCR 34 fork (120 mm travel, lockout) and a 40 mm travel suspension seatpost in aluminium — a thoughtful addition on a hardtail that makes a real difference on broken surfaces. The Moustache 660 mm ergonomic handlebar with 30° backsweep and SB3 grips encourage a relaxed, upright riding position.

Standard equipment includes an AXA NXT 80-lux headlight and rear LED, both powered by the main battery, an aluminium MIK HD rear rack with QL3 side mounts, double-wall mudguards, a bell, and an ABUS 4650SL lock sharing a key with the battery. Schwalbe Smart Sam 27.5×2.35 reflective tyres bridge the gap between gravel and tarmac. Frame and fork are covered by a 5-year warranty; motor and battery by 2 years.
