-Make sure your charger is isolated from liquids, dirt, and debris.
We set up every new e-bike to make sure it's ready to ride, but it's normal for some parts to work a little loose. To make sure you enjoy many years of smooth riding, we recommend getting your new bike checked by a professional after three months or 1000km of riding. Here's what they'll do:
-Tighten and lube the chain
- Adjust the brakes
- Align the wheels
- Check the gearing
- Retighten all bolts
- Lube the brake and shift cables
- Check the tire pressure
Currently, our e-bikes do not feature regenerative brakes. However, we truly appreciate your suggestion and will definitely consider this feature for our future product development.
Pedal assist uses a cadence sensor built into the drivetrain of the e-bike. The sensor detects when the rider is revolving the pedals and signals the electric motor to provide the level of pedal assistance that has been selected.
