It does not include parts subject to normal wear and tear (Brake Pads, Spokes, Tubes, Flywheel Pinion, Saddle, Kickstand.) and improper assembly or follow-up maintenance. See the complete warranty details here.
How often should I get my bike serviced?
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
What is pedal assist?
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.

For your and your bicycle's safety and the laws in your location, please understand that we cannot provide "cheat codes" to our dear supporters.
