FAQs

What is the range of the TQ 360Wh battery?

The range varies significantly based on factors like rider weight, terrain, assist level, and pedaling effort. TQ's system is designed for efficiency, but expect anywhere from 40 to 100+ miles on a single charge under typical conditions.

Can I use this bike on gravel or off-road trails?

The Domane+ ALR 5 is equipped with 700x32mm tires and has mounts for mudguards, making it suitable for light gravel, fire roads, and well-maintained dirt paths. However, it is primarily designed as an electric road bike and may not be ideal for aggressive off-road riding.

How much power does the TQ HPR60 motor provide?

The TQ HPR60 motor offers 60 Nm of torque and has a 300-watt maximum continuous rated power, with a peak power of 350 watts. This provides a natural-feeling assist that complements your pedaling.

What is the maximum rider weight limit?

The manufacturer's maximum rider weight limit for this bike is typically around 300 lbs (136 kg), including the bike and gear. Always consult the official Trek specifications for the most accurate information.

Is the battery removable?

Yes, the TQ 360Wh battery is designed to be removable, allowing for convenient charging off the bike and potential for carrying a spare battery on very long rides, though spare batteries are sold separately.

What type of controller does it use?

The bike features a TQ LED display with Bluetooth and ANT+ connectivity, allowing you to monitor ride data and control assist levels directly from the handlebar.

Troubleshooting

Motor not providing assistance

Ensure the battery is charged and properly seated. Check that the system is turned on and the assist level is selected on the TQ LED display. Verify that the wheel speed sensor is clean and aligned.

Display not powering on

Confirm the battery has a charge. Check the connection between the display and the main wiring harness. If the issue persists, contact customer support.

Inconsistent shifting

Check the derailleur hanger for bends. Ensure the chain is clean and lubricated. Adjust the rear derailleur indexing if necessary, or consult a bike mechanic for a professional tune-up.

Brakes feel weak

Inspect brake pads for wear. Check hydraulic fluid levels and look for any leaks in the brake lines. If necessary, the brakes may need to be bled by a qualified mechanic.

Pros and Cons

Pros

  • Provides a natural and quiet pedal-assist experience.
  • Capable drivetrain for varied terrain and gradients.
  • Durable aluminium frame suitable for daily use.

  • Tubeless-ready setup for improved performance and comfort.

Cons

Setup, Compatibility & Care

Setup:

Upon receiving the bike, professional assembly is recommended. Key setup steps include installing the handlebars, stem, seatpost, saddle, and pedals. Ensure all bolts are tightened to the manufacturer's specifications. The TQ LED display should be paired with your smartphone via Bluetooth for advanced settings and ride tracking using the TQ app.

Compatibility:

  • Drivetrain: SRAM Apex 12-speed components are designed for seamless integration.
  • Brakes: SRAM Apex D1 hydraulic disc brakes offer reliable stopping power.

Care:

  • Cleaning: Clean the frame and components regularly with a soft cloth and mild soap. Avoid high-pressure water jets, especially near the motor and battery.
  • Drivetrain Maintenance: Keep the chain lubricated and clean. Regularly check the cassette and derailleur for wear and proper adjustment.
  • Battery Care: Store the battery in a cool, dry place. Avoid full discharge. Consult the TQ app for specific battery health recommendations.
