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: 135kg(298lb), 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.

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 ebike
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.

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
.
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.
