Extended Product Information

FAQs

How long does the 800Wh battery last?

Battery range varies significantly based on elevation, rider weight, and support mode, but generally supports 60-100+ miles in Eco mode.

Can I fit a child seat to this bike?

Yes, the frame includes mounting points for racks, which can often support specific child seats, but check compatibility with your chosen seat brand.

Is the bike waterproof?

It is weather-resistant and safe for riding in rain, but should never be submerged in water or cleaned with a high-pressure jet washer.

What is the benefit of the four-piston brakes?

Four-piston brakes provide more contact area between pads and rotors, offering superior heat management and stopping power for heavier e-bikes.

Can I use the bike without motor assistance?

Yes, you can ride it like a standard bike, though the motor and battery weight make it physically more demanding to pedal than a non-electric bike.

Troubleshooting

Motor assistance feels intermittent

Ensure the battery is firmly clicked into the frame and the speed sensor magnet is correctly aligned with the sensor on the rear wheel.

Brakes feel spongy

This indicates air in the lines; the hydraulic system requires bleeding by a certified professional.

Display not connecting to the system

Check all cable connections near the handlebar stem and ensure the system controller is fully charged or properly seated.

Pros and Cons

  • Reliable and precise Shimano XT drivetrain
  • Versatile mounting points for commuting accessories
  • Confidence-inspiring 2.6-inch grippy tyres

  • Larger battery size increases overall bike bulk

Setup, Compatibility & Care

To ensure optimal performance, verify that your tyre pressure is set to the manufacturer's recommended range for your body weight and trail surface. Since the bike features a high-capacity 800Wh battery, always use the dedicated Bosch-approved charger and avoid storing the battery in extreme heat or freezing temperatures to maintain longevity. Periodically check that all frame mounting bolts are tight if you choose to install racks or mudguards. Keep the drivetrain clean and lubricated, especially after off-road use, to preserve the life of the Shimano XT chain and cassette. If the bike is tubeless-ready, ensure you check the sealant levels every 3-6 months.
