ALVAS JUMP GREY
Built for riders who want to send it with absolute confidence, the Alvas Jump 26-inch is engineered to dominate dirt jumps, local pump tracks, and street lines. At the heart of this playful rig is a durable, lightweight aluminium dirt jumper frame that is structurally reinforced to take a beating while maintaining incredible agility and responsiveness in the air. Internal cable routing keeps the lines clean and protected during barspins or whips, while the robust front suspension fork with stout 34 mm stanchions smoothly cushions heavy impacts and casings. Featuring powerful Shimano hydraulic disc brakes and a bulletproof single-speed drivetrain, this bike delivers premium, hard-hitting performance that is ready to throw down session after session.

Why this bike is for you
You want a dedicated, premium-value 26-inch dirt jumper specifically dialled for flow lines, skateparks, and pump tracks.
You prefer the elite stopping power and modulation of Shimano hydraulic disc brakes over traditional mechanical options or BMX U-brakes.
You want a highly reliable, low-maintenance single-speed setup that allows you to focus purely on progression and style without worrying about dropping chains.
Why this bike may not be for you
You are looking for a multi-geared mountain bike with a wide-range cassette to climb steep hills or go on long-distance trail rides.
You are looking for a traditional, smaller 20-inch freestyle BMX for tight street riding or grind peg capability.
For safety reasons bikes can not be shipped partially assembled; they must be fully built and inspected by an authorised technician prior to collection or delivery.
