Product Information
Full details
The Trek District+ 4 is designed for urban commuters and city riders who prioritize low-maintenance reliability and a comfortable, upright riding position. Featuring a quiet belt drive and a robust Bosch Performance Line motor, it excels at handling daily city traffic and errands with minimal upkeep. While its integrated battery system and high-quality components provide a premium experience, potential owners should note that the 400Wh battery capacity is optimized for shorter to mid-range urban commutes rather than long-distance touring.

FAQs
Can I replace the 400Wh battery with a larger one?
The frame design supports semi-integration; check with your local Trek retailer regarding compatibility with higher-capacity Bosch batteries for this frame size.
Is the belt drive compatible with traditional chain cleaners?
No, belt drives should not be treated with chain oil or heavy solvent-based degreasers. Simply rinse with water and a soft cloth.
How do I check my remaining range?
The remaining range is displayed on the Bosch controller unit on your handlebars and can also be monitored via the connected smartphone app.
Are the lights powered by the main battery?
Yes, the integrated front and rear lights draw power directly from the main Bosch battery system.
Does the bike come with a charger?
Yes, a compatible Bosch charger is included with the bike purchase.
Is this bike waterproof?
The electrical components are weather-resistant and designed for commuting in rain; however, you should avoid pressure washing or submerging the motor and battery.
Troubleshooting
Motor power is not engaging
Check that the battery is properly seated in the frame and that the Bosch controller is powered on.
Shifting feels stiff or skips
Ensure the shifting cable is free of debris and consult an authorized service center for a cable tension adjustment.

Setup, Compatibility & Care
To keep your District+ 4 in peak condition, regular maintenance is essential. Ensure the belt drive remains free of heavy debris by rinsing it with water during your bike washes. The Bosch battery should be kept in a cool, dry place when not in use for extended periods, and you should avoid charging it in extreme temperatures.
Compatibility with the Bosch Smart System requires the installation of the companion app on your smartphone to fully leverage the activity tracking and anti-theft features. We recommend having the internal hub serviced by an authorized Trek or Shimano dealer annually to ensure the shifting remains crisp. Always verify tire pressure before every ride to maximize both the battery range and the puncture protection of the Bontrager E6 tires.
