Power that makes every ride easier

The GT900's brushless 250W motor delivers smooth, reliable assistance up to 15.5 mph, helping you cover more ground with less effort. It's designed to be efficient, so you get a longer ride from each charge, making your daily commute or weekend spin both cheaper and greener. Whether you're nipping to the shops or exploring country lanes, this motor turns every trip into a pleasure.

Ride up to 43 miles on a charge

Enjoy long countryside spins without worrying about running out of power. The 36V 13Ah lithium-ion battery gives you over 43 miles of pedal-assisted range, so you can explore bridleways and country lanes with confidence. A full charge takes just 5 to 6 hours, and the built-in battery management system monitors 14 safety functions to protect the cells and extend battery life. Keep in mind that actual range depends on your weight, the terrain, and how much assist you use.

Key card unlock and three riding modes

Start your ride with a simple tap of the key card—no fumbling with keys. You can choose between pure pedal power or switch on the motor for effortless cruising. The pedal-assist system offers five levels of support, letting you dial in exactly how much help you want, from a gentle nudge on flat towpaths to full power on steep climbs. It’s all about riding your way, whether you’re commuting through town or tackling a weekend trail.

Stay informed with the LED display

Glance down and you’ll see everything you need at a moment’s notice. The integrated LED screen shows your current battery level and the chosen assist mode, so you’re always in control. It’s clear and easy to read, even in bright daylight, helping you plan your ride without distraction.

Smooth shifting with Shimano 21-speed gears

Find the perfect gear for every hill and headwind. The Shimano 21-speed drivetrain delivers crisp, reliable shifts with no lag, so you can maintain a steady cadence on any gradient. Whether you’re spinning along a flat B-road or grinding up a steep off-road track, the wide gear range keeps your ride smooth and efficient.

Ride smoothly over any surface

Dual front and rear suspension soaks up bumps and shocks, so you stay comfortable whether you're on paved lanes or rough mountain trails. It takes the sting out of uneven ground, helping you keep control without feeling every jolt through the handlebars. This setup is ideal for UK bridleways and potholed country roads alike.

Powerful front and rear disc brakes give you confident, reliable stopping in all conditions. They deliver smooth, progressive braking even on steep descents or in wet weather, which is a real bonus on Britain's often damp roads. Your safety comes first, and these brakes help you ride with peace of mind.

Tackle any terrain with confidence

Large 26-inch by 1.95-inch tyres provide excellent grip and stability across everything from gravel tracks to muddy paths. They roll over obstacles easily, giving you the freedom to explore off-road routes without hesitation. A shock-absorbing saddle bag adds an extra layer of comfort, smoothing out the ride when the going gets bumpy.

See and be seen after dark

A bright LED headlight makes night riding as safe and straightforward as a daytime spin. It illuminates the road ahead clearly, so you can spot potholes and turns early, even on unlit country lanes. This is essential for UK winters when daylight fades quickly, helping you stay visible to other road users.
