FAQs
How do I remove the battery for charging?
The TQ battery is integrated into the frame. Refer to the specific TQ system manual for detailed instructions on battery removal, which typically involves accessing a port and using a specific tool or procedure to release the battery.
What is the range of the TQ 580Wh battery?
The range can vary significantly based on factors like rider weight, terrain, assist level, and pedaling effort. However, the 580Wh battery is designed to provide ample range for extended trail rides.
Can I use other chargers with the TQ battery?
It is strongly recommended to only use the TQ-specific charger provided with the bike to ensure proper charging and prevent damage to the battery or charging system.
What tire pressure should I use?
Recommended tire pressure depends on rider weight, tire model, and trail conditions. A good starting point for the Bontrager Gunnison Elite XR 2.40" tires is typically between 20-30 PSI, but it's best to experiment for optimal grip and comfort. Check tire sidewall for maximum pressure.
How much travel does the suspension have?
The bike features 150 mm of travel at the front fork and 145 mm of travel at the rear shock.
Is this bike suitable for beginners?
Yes, the e-assist and capable suspension make it accessible for beginners looking to tackle trails. However, a basic understanding of mountain biking techniques and e-bike operation is advised.
What is the warranty on the Trek Fuel+ EX 5?
Trek typically offers a limited lifetime warranty on the frame and a one-year warranty on components and the e-bike system (motor, battery, controller). Please refer to the official Trek warranty documentation for precise details.
Troubleshooting
Motor not providing assistance
Ensure the battery is charged and properly seated. Check that the system is powered on and that no error codes are displayed on the TQ LED display. Verify that the speed sensor is clean and aligned correctly.
Brakes feel weak or spongy
Check the brake fluid level and inspect for leaks. The brakes may require bleeding if air has entered the system. Ensure the brake pads are not worn out and the rotors are clean.
Shifting is imprecise or noisy
Inspect the rear derailleur for any damage or misalignment. Adjust the derailleur hanger if necessary. Ensure the gear cable is not frayed and is properly tensioned. Lubricate the chain.
Suspension feels harsh or bottoms out easily
Check and adjust the suspension sag according to your weight and riding style. Ensure the rebound and compression settings are appropriate for the terrain. Service the suspension if it hasn't been done recently.

Setup, Compatibility & Care
Initial Setup: Upon receiving the bike, ensure all components are securely fastened. It is highly recommended to have the bike assembled and inspected by a qualified bicycle mechanic before the first ride. This includes checking tire pressure, brake function, suspension sag, and drivetrain adjustments.
Compatibility: The bike utilizes standard Boost148 spacing for the rear wheel and Boost110 for the front. The frame is designed for a ZS headset and features an adaptable travel range. The UDH (Universal Derailleur Hanger) ensures compatibility with a wide range of modern drivetrains. The TQ system uses specific charging components; always use the charger provided with the e-bike.
Care:
Cleaning: Clean the bike regularly with water and mild soap. Avoid high-pressure washers, especially around bearings and the e-system components. Wipe down the frame, motor, and battery area with a damp cloth. Ensure the bike is dry before storing.
Battery: Store the battery in a cool, dry place between rides. Avoid extreme temperatures. Refer to the TQ system manual for specific charging and storage recommendations.
Drivetrain: Keep the chain clean and lubricated. Regular maintenance of the derailleur and cassette will ensure smooth shifting.
Suspension: Follow the manufacturer's guidelines for suspension service intervals to maintain optimal performance and longevity.
