Can I remove the battery for charging?
The battery is designed to be dealer-removable. This means it's not intended for frequent user removal for charging, contributing to the bike's integrated and secure design.
What is the maximum speed for motor assist?
The TQ HPR50 motor provides assistance up to 15.5 mph (25 km/h in Europe).
Is this bike suitable for off-road trails?
The FX+ 7 Midstep is primarily designed for urban environments and paved surfaces. While it can handle light gravel paths due to its tires, it is not intended for aggressive off-road riding on technical trails.
What accessories are included with the bike?
The bike comes equipped with built-in front and rear lights, a kickstand, and a MIK-compatible rear rack with side mounting options.
How do I maintain the TQ motor system?
Keep the motor area clean and free of debris. Avoid pressure washing directly on the motor housing. For any system faults or maintenance beyond basic cleaning, consult the TQ system manual or a Trek service center.
What is the warranty on the bike and electric components?
Trek offers a limited lifetime warranty on the frame and a warranty on components, including the electric system. Specific details and duration should be confirmed with your Trek dealer or on the Trek website.
Troubleshooting
Motor does not provide assist
Ensure the battery is charged and properly seated. Check that the system is turned on and the assist level is selected. Verify that the speed sensor is aligned correctly and not obstructed. If the issue persists, consult the TQ system manual or a Trek dealer.
Display is not working
Check the battery connection to the display unit. Ensure the battery has sufficient charge. If the display remains blank, it may require service from a Trek dealer.
Brakes are noisy or feel weak
Inspect brake pads for wear and clean rotors with isopropyl alcohol. Ensure brake lines are not kinked. If performance is still compromised, the brakes may need bleeding or adjustment by a professional.
Gears are not shifting smoothly
Check the derailleur hanger for bends. Ensure the derailleur cable is properly tensioned. Clean and lubricate the chain and cassette. For persistent issues, a professional adjustment may be needed.
Bike makes unusual noises
Identify the source of the noise. Check for loose bolts on accessories, the frame, or components. Inspect the drivetrain, wheels, and headset for play or wear. If the noise continues, seek assistance from a qualified mechanic.
