Long-lasting battery for extended rides

Comfortable ride on fat tires
The 16-inch pneumatic fat tires absorb bumps and provide stable handling on UK roads. Whether you're on smooth tarmac or slightly rougher paths, the ride stays smooth and controlled. The bike's compact size also makes it easy to manoeuvre in tight spaces.
Reliable stopping power in all weather
Front and rear disc brakes give you confident stopping power, even in wet conditions. The IP54 waterproof rating means light rain won't stop your ride. You can trust the brakes to respond quickly when you need them most.
Simple controls for effortless riding
The display keeps essential information like speed and battery level at a glance. Controls are intuitive, so you can focus on the road ahead. It's designed to make every ride straightforward, whether you're a first-time e-bike rider or experienced.
Built tough for everyday use
The durable frame supports up to 265 lbs, making it suitable for a wide range of riders. At 77 lbs, it's sturdy yet still manageable to store in a flat or garage. The bike comes in black, blue, or pink, so you can choose the style that suits you.
