PANORAMIC VIEW

21 Gears. Built To Climb.

250W brushless rear hub motor. Up to 500W when you push it. Pair it with 21-speed Shimano and you have the answer to every gradient and every commute.

80 KM. One Charge.

468Wh lithium-ion battery integrated in the down tube. PAS mode takes you up to 80 km per charge.* Removable — charge it at home, at the office, wherever.
(Actual range may vary depending on rider weight, terrain, temperature, tyre pressure and assistance level.)

Shimano. Total Control.

The SY26-II runs a 21-speed Shimano drivetrain — a 21-speed range for city flat, steep climb, and technical descent. You choose the exact gear for the moment. The motor assists. You control the output.

26 Inches. Steady Grip.

26" all-terrain wheels. City tarmac, gravel tracks, moorland paths, light trail — the SY26-II handles all of it. Larger diameter means less rolling resistance, more stability, and more ground clearance on rough terrain.

Suspension

Front suspension fork absorbs gravel, roots, and urban potholes before they reach you. Comfortable on long commutes and technical trail alike.

Mechanical disc brakes front and rear. Consistent stopping power on wet tarmac, muddy tracks, and steep descents. Reliable in all UK weather.

21-Speed

Shimano 21-speed drivetrain. The 21-speed range for city flat, steep climb, and technical descent. From flat city sprint to steep moorland climb — the right gear every time.

Tires

26" all-terrain tyres. Lower rolling resistance than fat tires, more grip and ground clearance than city tyres. Built for roads and trails.

The riding position feels natural and relaxed. I don’t feel stretched forward, and I can ride for longer without discomfort in my shoulders.

I’ve used the XD26 on roads, gravel tracks and a few rough countryside paths. The suspension makes a noticeable difference and the bike feels controlled when the surface becomes uneven.

I originally bought the RS-A01 for occasional rides, but I now use it for work and local shopping. It has replaced more short car journeys than I expected.

What does 21-speed mean in practice?

21-speed gives you a wide range of gears. In practice: you have a low gear for steep climbs (even without motor assist), a high gear for flat sprints, and 19 options in between. Combined with the PAS motor, you have precise control of effort on any terrain.

Safety Precautions

⛑  Before your first ride

Check tyre pressure, brakes, and all fasteners before every ride. Assemble handlebar, pedals, and front wheel as shown in the manual.

🪖  Always wear a helmet. We recommend high-visibility clothing, especially in low-light conditions.

⚡  Battery & charging

Charge with the supplied VOOLM charger only. Do not charge overnight unattended or near flammable materials. If the battery shows damage, swelling, or unusual heat — stop use immediately and contact support.

🔧  Maintenance

Do not modify the electronic control system. Unauthorised modifications void the warranty and may create safety risks. Service the brakes and drivetrain regularly.
