The Trek Domane+ ALR 5 is an aluminum electric road bike designed for riders seeking a natural-feeling boost on long rides and climbs. It offers a smooth, quiet assist from its TQ HPR60 motor, complemented by a reliable SRAM Apex 12-speed drivetrain for precise shifting. While it enhances endurance and tackles hills with ease, it's important to note that it is an electric-assist bike, not a fully-powered scooter, and requires rider input.

Do I need to pedal for the motor to work?
Yes, the TQ HPR60 motor is a pedal-assist system. You must be pedaling for the motor to provide support. It is designed to feel like a natural extension of your own effort.
What is the maximum weight capacity of the bike?
While specific maximum weight is not detailed here, Trek bikes are generally designed to support a combined rider and cargo weight of up to 300 lbs (136 kg). Always refer to official Trek specifications for precise limits.
Can I ride this bike in the rain?
Yes, the Domane+ ALR 5 is designed for various weather conditions. However, it is recommended to clean and dry the bike after riding in wet conditions to maintain its longevity.
What size tires does this bike accommodate?
The bike comes with 700x32mm tires. The frame and fork generally accommodate tires up to 35mm wide for comfortable riding.
Is this bike suitable for gravel riding?
With its 32mm tires and road-biased geometry, it's suitable for light gravel or smoother unpaved paths. For more aggressive gravel riding, wider tire clearance might be preferred.
How do I check the system's error codes?
Error codes are typically displayed on the TQ LED controller. Refer to the TQ system manual or consult a Trek dealer for a comprehensive list of codes and their meanings.
Troubleshooting
Motor not providing assist
Ensure the battery is charged and properly connected. Check that the bike is in an appropriate assist mode via the controller. Verify wheel speed sensors are clean and correctly positioned.
Inconsistent shifting
Check the rear derailleur hanger for bends. Ensure the gear cable is not frayed or kinked. Adjust the derailleur limit screws and B-tension if necessary.
Brakes feel weak or spongy
Inspect brake pads for wear and clean rotors. If the lever feels spongy, the hydraulic system may need bleeding. Consult a qualified mechanic.
TQ LED display not functioning
Check the display connection. Ensure the battery is charged. Try restarting the system. If issues persist, consult the TQ system manual or a dealer.
