Extended Product Information

FAQs

How long does it take to charge the 800 Wh battery?

Charging times vary based on the charger output, but a full charge typically takes several hours. It is recommended to use the official Bosch charger provided.

Can I swap the wheels to a full 29-inch setup?

The bike is optimized for the mixed-wheel (mullet) configuration; altering this may change the geometry and handling characteristics significantly.

Is the frame covered by a warranty?

Trek offers a limited lifetime warranty on the frame for the original owner. Refer to the official Trek warranty documentation for full terms.

How often should I service the suspension?

Fox suspension components should be serviced according to the manufacturer's recommended intervals, typically every 50 to 125 hours of riding, depending on conditions.

Do I need to charge the AXS shifting battery separately?

Yes, the SRAM AXS derailleur has its own small, removable battery that must be charged independently of the main bike battery.

Troubleshooting

Wireless shifting is unresponsive

Check the battery level on the SRAM AXS derailleur and ensure it is securely seated.

Motor assistance feels intermittent

Ensure the speed sensor magnet is properly aligned and check that the battery is fully locked in the frame cradle.

Suspension feels harsh

Check sag settings; you may be running too much air pressure for the current trail surface.

Setup, Compatibility & Care

Battery Care: Always store the RIB 2.0 battery in a cool, dry environment and keep it charged between 30% and 60% for long-term storage.
Suspension Tuning: Set the sag on the FOX Float 38 and Float X according to your body weight. Adjust rebound and compression damping based on the trail conditions.
Firmware Updates: Regularly connect the bike to the Bosch Flow app to ensure the motor and battery management systems have the latest performance updates.
Cleaning: Use low-pressure water to clean the bike. Avoid high-pressure washers, as they can force water into sensitive electronic connections or bearing seals.
Drivetrain Maintenance: Clean and lubricate the chain frequently, ensuring that the AXS battery remains charged to maintain shifting performance.
