You must familiarize yourself with all aspects of your E-bike’s electrical system and check if everything is working correctly before each ride. The front and rear brake levers contain motor cutoff switches. They disable the hub motor’s assistance. Both levers should be checked if they are working correctly. When choosing a higher power assist level, the hub motor should provide smooth, gradual acceleration of the engine’s power. Should the power assist, lighting, or motor levels function abnormally, intermittently, or not work at all, please stop using your e-bike immediately and contact our support team for assistance.

Brake System
Do not use the front brake by itself. Apply the rear brake first, and then the front brake. Ensure that brakes function normally and that all components of the braking system are properly secured without any damage. When you fully squeeze the brake levers, ensure that neither the front nor the rear brake lever touches the handlebars. Add tension to the brake cables or take your bike to a certified bike mechanic to have the brakes repaired when you face any problems.

Derailleur
Because the derailleur is easy to damage, after assembling the e-bike, first check whether the protection of the derailleur is bent, if you find the protection of the derailleur is bent, you can take it perpendicular to the ground
by hand.

Tires and Wheels
Your wheels should always spin straight and must be repaired or replaced if they wobble from side to side or up and down when spinning. If your wheels are loosened, which could happen after use, we recommend having a certified bike mechanic to tune the wheels of your E-bike. Do not attempt to tune wheels or tighten spokes unless you have adequate knowledge, tools, and experience. Ensure the tires and inner tubes to be in good working condition with the correct amount of air pressure as indicated on the tire sidewall and without any visual damage. Always replace tires and inner tubes if they have punctures, cuts, or damages before your rides. Tires without the correct amount of air pressure could reduce performance, cause tires to wear faster, and make riding your bike dangerous.

Suspension, Handlebar, Grips
The suspension fork should be properly adjusted for your weight and terrain. Make sure that the handlebar and the handlebar stem are properly aligned, fitted to the user, and secured to their corresponding, recommended torque values. Handlebar grips should not move easily at the ends of the handlebar. Loose, worn, or damaged handlebar grips should be replaced before rides.

Quick releases, Accessories, Straps, and Hardware
Quick-release levers are for securing the seat post and the front wheel to the bike. They allow the user to remove the front wheel and to adjust the seatposts without tools. Since quick release levers could be loosened during transportation, or accidentally between or during rides, you must regularly check to ensure these components are properly secured.

Ensure all hardware is secured and all approved accessories are properly attached following the instructions of the specific component’s manufacturer. It is always helpful to look over all hardware, straps, and accessories before each ride and, if you discover something wrong or find something you are unsure of, have it checked by a certified bicycle mechanic.
Before using the e-bike, always check to ensure all levers, quick releases, and latches are properly secured and undamaged.

Changing Components or Attaching Accessories
The use of non-original components or spare parts can jeopardize the safety of your E-bike, void your warranty and, in some cases, cause your E-bike to not conform with laws pertaining to operating your bike.

Helmets
We recommend riders wear a properly fitted helmet that covers the forehead when riding a bike. Child passengers also should wear a properly fitted helmet.
