FAQs

How long does the 800Wh battery last?

Range depends on rider weight, terrain, and assistance level, but the 800Wh battery typically offers significantly more range than standard 500Wh or 625Wh units.

Can I fit different tyres on this bike?

The frame clearance is designed for the included 2.6-inch tyres; always check with a professional mechanic before sizing up to ensure sufficient clearance.

Is the suspension adjustable?

Yes, the RockShox Recon Silver air fork allows you to adjust air pressure and rebound damping to suit your weight and riding style.

How do I perform a firmware update?

Firmware updates for the Bosch drive system should be performed by an authorized Cube dealer using specialized diagnostic tools.

Is this bike suitable for bikepacking?

Yes, its robust construction, long-range battery, and wide gear range make it an excellent choice for long-distance, multi-day rides.

What is the benefit of a 4-piston brake system?

A 4-piston system provides more surface area and clamping force than a 2-piston system, resulting in better heat management and stopping power for heavier e-bikes.

Troubleshooting

Motor assistance feels intermittent

Check that the speed sensor magnet is correctly aligned with the sensor near the rear wheel.

Battery will not charge

Verify the charger connection is secure and test the wall outlet; if the issue persists, contact an authorized service center to check the battery contacts.

Brakes feel 'mushy' or soft

The hydraulic system may need bleeding to remove air bubbles, or the brake pads may be worn down past their service life.

Setup, Compatibility & Care

Proper setup is essential to maximize the performance of your e-bike. Ensure the RockShox Recon air fork is correctly pressurized for your body weight using a shock pump. Regularly check the air pressure in your tires to suit the terrain—lower pressures provide more grip, while higher pressures reduce rolling resistance on pavement.

Maintenance requirements include cleaning the drivetrain after muddy rides to prevent premature wear on the 12-speed chain. Always keep the Bosch system updated with the latest firmware via authorized service centers. Check your brake pad clearance periodically, especially if you ride frequently in grit or rain, and ensure the battery is stored in a cool, dry environment when not in use for extended periods.
