URBAN CONTROL
The lightweight ALX alloy frame feels light and responsive in everyday riding. The riding position keeps you upright and balanced, helping the bike feel stable at low speeds, easy to control in traffic, and giving clear visibility through busy streets.
BUILT FOR MIXED SURFACES
A 63mm SR Suntour suspension fork and wide 45mm tyres help smooth rough pavement, kerbs, and gravel paths. The front wheel stays planted over bumps, improving stability and control while keeping everyday rides efficient and comfortable.
PRACTICAL & SIMPLE
A simple 1x drivetrain reduces shifting complexity and everyday upkeep. Rack and mudguard mounts make it easy to carry gear or add protection from the elements, making the bike a practical choice for commuting and everyday transport.
SR SUNTOUR NVX32 AIR FORK
The SR Suntour NVX32 Air fork offers 63mm of travel to absorb vibrations from bumpy roads, cracks, and light gravel. An adjustable air spring lets you precisely tune the fork to your exact weight and riding style, providing a lighter, more responsive feel on uneven surfaces.
SUSPENSION SEATPOST
The alloy suspension seatpost uses a built-in coil spring to soak up sharp impacts from potholes and uneven surfaces. This mechanical cushioning provides a smoother, more comfortable ride that reduces body fatigue during longer commutes or weekend adventures.
SHIMANO DEORE 1×12 DRIVETRAIN
The Shimano Deore 1×12 drivetrain offers a massive gear range to simplify steep climbs and fast descents. A single shifter manages all 12 gears with precision, while the clutched rear derailleur keeps the chain secure and quiet when riding over kerbs or rougher terrain.
SHIMANO HYDRAULIC BRAKES
Shimano MT200 hydraulic disc brakes provide powerful, consistent stopping in both wet and dry conditions. The hydraulic system allows for easy one-finger braking, giving you total control and confidence when navigating traffic or steep descents.
VERSATILE WHEELS + WTB TYRES
Double-wall alloy rims with 700x45c WTB Riddler tyres deliver fast-rolling efficiency with reliable grip on unsealed paths. This high-volume setup provides a stable, puncture-resistant ride that improves comfort and confidence when transitioning between different surfaces.

Buy One, Plant One
Since January 2020 we have worked with not-for-profit reforestation partners to donate enough money to pay a local person a fair wage to grow, plant and guard to maturity 1 native tree for every bike we sell.
We've now planted more than 400,000 trees and counting!
