400W motor + Shimano 7-speed

The Q7 is built to feel confident on everyday routes, combining a 400W motor with a Shimano 7-speed drivetrain. That mix makes it easier to hold a steady pace on longer rides and keeps pedalling comfortable when the road tilts up. Assist support is designed for commuting, leisure rides and light off-road paths.

36V 10Ah battery for daily miles

A 36V 10Ah battery gives reliable capacity for regular trips, with TrailSurge listing up to 40 miles of range depending on conditions. Charging is typically 5-6 hours, which suits overnight top-ups. For best results, keep tyre pressure up and use assist levels that match your terrain.

Grip, braking and NFC security

Wide 26 x 2.6 off-road tyres add grip and stability on gravel, towpaths and uneven lanes. Dual mechanical disc brakes help you manage speed with confidence in wet or dry weather. NFC functionality provides convenient access control, and the bike is supplied with useful extras like a tool kit and fenders.
