· Adjusting the Suspension Fork The suspension fork can move up and down up to 80 mm to cushion bumps in the riding surface, which can make riding on a rough road or trail smoother and more comfortable. In addition, depending on a rider²s preference, the suspension fork can be locked out as a rigid fork, which will typically yield higher pedaling efficiency.
The lockout lever 1 located on top of the right side of the suspension fork, can be turned counterclockwise until it stops to lock out the suspension fork²s motion completely. To unlock the lockout lever, turn the knob clockwise until it stops. When the lockout lever is unlocked, resistance can be adjusted by turning.
The pre-load adjustment knob 2 is located on the top of the left side of the suspension fork. To soften the ride, reduce resistance by turning the pre-load adjustment knob counterclockwise, in the direction of the small "-" on the knob. To make the suspension stiffer when going over bumps, add resistance by turning the pre-load adjustment knob clockwise, in the direction of the small "+" on the knob.

Note for Parents and Guardians As a parent or guardian, you are responsible for the activities and safety of your child. The ebike is not designedfor use by children. If you are carrying a passenger in a child safety seat, they must also be wearing a properly fitted and approved helmet.
Components Notice
Carrying Loads Total maximum payload: 120kg(265lb), includes the weight of the rider as well as cargo, passengers
and riding tools. Optional rear rack maximum payload: 25 kg (55 lb) Optional front rack maximum payload: 15 kg (33 lb)
You MUST hold onto the bike when loading passengers or cargoes. The kickstand is not designed to be used for loading passengers or cargoes. Do not assume the bike is stable and balanced when using the kickstand. Always hold onto the bike when passengers or cargo are being loaded.
Never leave the bike unattended with a child on the bike. Ensure that the child is taken with you when you look away or walk away from the bike, otherwise the bike could tip over and cause serious injury or death.
35

Carrying Cargo Carrying a cargo load involves additional risks, which requires special attention and care. Braking, acceleration, and balancing are all significantly affected by the cargo loaded on the e bike. To safely operate your e bike while carrying cargoes, you must get used to the differences in braking, steering, balance, etc that come with the extra weight. · Ensure that your loads are properly secured and check periodically that nothing loosens or at risks of interfering with any moving components, or touching or dragging on the ground. · Hills that are normally easy to climb and descend without cargo can become challenging and dangerous once cargo is loaded onto the bike, as the extra weight affects steering, braking, balancing as well as the amount of power it takes to go uphill. · With the user's ability to safely operate the ebike. Serious injury or death can occur if the user²s ability to safely operate the ebike is compromised by the cargoes or passengers on board.
36

Electrical System The electrical system of your e bike offers various levels of power assistance for different operating conditions and users' preferences. It is critical that you familiarize yourself with all aspects of your ebike'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 higher power assist level, hub m otor should provide smooth, gradual acceleration of engine's power. Should the power assist, lighting or motor levels function abnormally, intermittently, or not work at all, please stop the using your ebike 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 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 ebike, first check whether the protection of derailleur is bent, if you find the protection of derailleur is bent, you can take it perpendicular to the ground by hand.
37

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.
38

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, it is important that you regularly check to ensure these components to be properly secured. Ensure all hardware to be secured and all approved accessories to be properly attached following the instructions of 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 ebike, 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 warrantyand, in some cases, cause your ebike to not conform with laws pertaining to operating your ebike.
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.
