FAQs
What is the range of the TQ 360Wh battery?
The range depends heavily on factors like rider weight, terrain, assist level, and wind conditions. TQ motors are known for their efficiency, but specific range figures vary. Consult TQ documentation or experienced users for typical estimates.
Can I fit wider tires on this bike?
The bike comes with 700x32mm tires. While the frame and fork have clearance for mudguards, the maximum tire width may be limited by the frame's design and the mudguard clearance. It is generally suitable for tires up to 35mm, but specific compatibility should be verified.
Does the bike come with pedals?
No, the Trek Domane+ ALR 5 does not include pedals. You will need to purchase them separately to complete the bike.
What is the warranty on the TQ motor and battery?
Trek typically offers a warranty on their e-bike components, including the motor and battery. Please refer to the official Trek warranty documentation for specific details regarding the duration and coverage.
How do I perform basic maintenance on the electric system?
Basic maintenance involves keeping the system clean, ensuring the battery is properly charged and stored, and checking that all connections are secure. For complex issues or system updates, consult the TQ system manual or a Trek dealer.
Is this bike suitable for bikepacking?
With its integrated rack mounts and stable geometry, the Domane+ ALR 5 can be adapted for light bikepacking. However, its primary design is for endurance road riding, and its capabilities on rough off-road terrain will be limited.
Troubleshooting
Motor not providing assist
Ensure the battery is charged and properly seated. Check that the system is turned on and the assist level is selected. Verify connections to the motor and sensors are secure. Consult the TQ LED display for any error codes.
Inconsistent shifting
Check derailleur adjustment. Ensure the chain and cassette are clean and lubricated. A bent derailleur hanger can cause significant shifting problems; inspect it carefully.
Brakes are weak or noisy
Inspect brake pads for wear. Ensure rotors are clean and free of oil. If the system feels spongy, it may require bleeding; consult a professional.
TQ LED display not functioning
Ensure the display is securely connected. Check battery charge level. Attempt to reset the system by turning it off and on again. If issues persist, contact support.

Setup, Compatibility & Care
Initial Setup: As a performance bicycle, some assembly and adjustments may be required by a qualified bike mechanic. This includes fitting the handlebar, stem, seatpost, pedals (not included), and ensuring brakes and gears are properly adjusted. The TQ drive system and battery should be charged before the first ride.
Compatibility: The bike uses standard 12x100mm thru-axles for the front and 12x142mm for the rear. It features flat-mount disc brakes. The stem is Blendr-compatible for integrated accessory mounting. Ensure any accessories, such as racks or mudguards, are compatible with the specific mounts on the frame and fork.
Care:
Cleaning: Clean the frame and components with mild soap and water using a soft cloth or sponge. Avoid high-pressure washers, especially near the motor and battery.
Drivetrain: Regularly clean and lubricate the chain, cassette, and derailleur. The SRAM Apex 12-speed system requires proper adjustment for optimal performance.
Battery: Store the battery in a cool, dry place when not in use. Follow the TQ system's guidelines for charging and maintenance to prolong battery life.
Tires: Check tire pressure regularly. The tubeless-ready setup allows for lower pressures, improving comfort and grip.
