FAQs

Can I upgrade the battery to a larger size later?

The bike is designed for the integrated system; consult your local Trek retailer to see if your specific frame configuration supports a higher-capacity battery pack.

How do I shift gears while stopped?

Simply twist the grip shifter on the handlebar while the bike is stationary to select your desired gear.

Is the bike waterproof?

While the electrical components are weather-resistant and designed to handle rain, it should never be submerged in water or cleaned with a high-pressure hose.

How often should I charge the battery?

You can charge the battery after every ride or when the charge level is low. Lithium-ion batteries perform best when they are not left completely depleted for long periods.

Are the lights battery-powered independently?

No, the integrated lights are powered by the main Bosch battery system, so they will work as long as the bike is powered on.

Troubleshooting

Motor assistance not engaging

Ensure the battery is fully seated in the frame and that the Bosch Purion 200 controller is powered on.

Brakes feel soft or 'spongy'

This may indicate air in the hydraulic lines; take the bike to a local bike shop to have the brakes bled.

Battery will not charge

Check the charger connection and verify the wall outlet has power; if the issue persists, test with a different charger if possible.

Setup, Compatibility & Care

Before your first ride, ensure the battery is fully charged using the provided Bosch charger. Check that tire pressure is within the manufacturer's recommended PSI range printed on the sidewall. Since the drivetrain is internal, it requires very little maintenance, but it is recommended to have a professional technician inspect the hub lubrication annually. Keep the frame clean by wiping it down with a damp cloth; avoid high-pressure water sprayers near the motor and battery connection points to prevent moisture ingress. Periodically inspect the hydraulic brake pads for wear and ensure the integrated lights are clean and functional for safe night riding.
