FAQs
How long does it take to charge the battery?
Charging time depends on the capacity (400Wh to 800Wh) and the charger used, typically ranging from 3 to 7 hours for a full charge.
Can I use a child seat on this bike?
Yes, the frame and rack are robust, but ensure the child seat is compatible with the specific rack mount provided.
Is the bike water-resistant?
The electrical components are sealed for weather resistance, but it should not be submerged in water or cleaned with a high-pressure power washer.
Does the belt drive ever need lubrication?
No, carbon belt drives are designed to run dry and require no oil or grease.
How do I update the bike's software?
Software updates are managed through the Bosch smartphone app via a Bluetooth connection.
Troubleshooting

Ensure the speed sensor magnet on the rear wheel is correctly aligned with the sensor near the dropout.

Toggle Bluetooth off and on, ensure the Bosch Flow app is updated, and check that the bike is powered on.

Setup, Compatibility & Care
- Setup: Upon arrival, ensure the tires are inflated to the recommended PSI listed on the sidewalls. The Bosch Smart System should be paired via the mobile application to activate the motor and register your unit.
- Compatibility: The rack is designed for standard pannier bags. The frame geometry is a lowstep design, facilitating easy mounting and dismounting regardless of attire.
- Care: While the belt drive is low maintenance, occasionally rinse the drive with water to remove road salt or heavy grime. Store the bike in a climate-controlled environment, especially during winter months, to protect the longevity of the lithium-ion battery. Keep the battery charged between 30% and 80% if the bike is going to be stored for an extended period.
