Charge the battery to 100% before your rst ride.
When charging your e-bike: Before riding, check whether the screws in the following key parts are properly
tightened:
Use a rag or large brush to clean the dust when there is not much sludge on your
e-bike.
When there is a lot of sludge on your e-bike, use a brush and soapy water to wash
off the sludge, rinse it with clean water, and then dry it with a cloth.
Check the wear degree of the brake blocks after you have them cleaned to see if
they can ensure normal braking. Replace them promptly if they are seriously worn.
It is recommended to clean the e-bike after you ride it for about 200 km. You need
to clean the bike rst before you put it into storage if you plan to not ride for a long
period of time.
After all screws are properly tightened before the rst ride, check if they maintain
the same fastening performance when your e-bike reaches a 200 km riding
distance and at every 1,000 km after the initial 200 km.
It is recommended to check the fastening performance of screws at every 600 km
if you usually ride under complex road conditions.
Check the tire pressure by hand or with a tool and ensure the pressure is within
the range of 50-75 PSI/3.4-5.1 BAR.
Press the driving belt to check whether the belt tension is proper (you should
be able to press the middle part of the belt down 10-15 mm if the tension is
moderate).
If you want to use your e-bike on public roads, please make sure that you comply
with local riding regulations, for example those governing riding equipment,
control lights, and reectors.
Make sure that you wear the correct protective equipment. Always wear a helmet
and be visible.
When properly adjusted, the saddle should be at hip height.
Check and ensure that the front wheel quick release, handlebar, brakes, pedals,
and other related parts of the e-bike are properly fastened before you start to ride.
The brake settings vary by country/region. Check which brake lever acts on which
brake rst, and if it does not comply with your habits, we recommend that you
ask an expert to change the settings so that you can accurately brake the front
and rear wheels if an emergency occurs while you’re riding. If you encounter any
problems while riding, please brake rst (please brake the two wheels at the same
time to stop within the shortest possible distance).
Check the steering; the steering has a crucial impact on braking and riding safety.
We recommend that you purchase relevant insurance for bikes or e-bike riding in
your area so that you can contact your insurance company or agency promptly to
get adequate protection in the event of an accident.
i. Charge the bike indoors and keep it away from direct sunlight, rain or snow.
ii. Do not charge the bike with non-TENWAYS chargers.
iii. Ensure a proper ambient temperature. The best ambient temperature for the charger is 20℃
to 25. A lower temperature may lead to insufcient charging, while a higher temperature may
lead to overcharging.
iv. It is recommended to remove the charger immediately after the bike is fully charged to avoid
overcharging the battery.
i. Screws between the handlebar and the front fork stem.
ii. Screws between the brake lever and the handlebar.
iii. Screws between the brake clamps and front fork.
iv. Screws on the chainring

Daily inspections
Daily cleaning
Do not clean the bike with a high-pressure water gun, as this might damage the mechanical pivots
and related mechanical tting parts.
26 27

Routine maintenance
It is recommended to go to a professional store for maintenance 2-3 times a quarter,
or after every 1,000 km of riding. The following items should be checked during such
maintenance:
Operating and storage temperatures of the battery
Working temperature of the lithium battery is 0°C to 30°C.
It is recommended that the lithium battery be stored in an environment where
the temperature is 0°C to 25°C, and the humidity is 65 ± 20% RH.
The performance of lithium batteries is affected by the ambient temperature.
Don't worry if the performance of your battery degrades during cold weather. The
battery performance will resume when the temperature rises.
If possible, the battery should not be charged above 95% or discharged below 10%,
as this may decrease battery life. A reasonable charging and discharging scheme
can mitigate accelerated battery deterioration.
Keep the power at 50% to 70%, check the battery condition every 2 months to
avoid damage caused by over-discharging, charge and discharge the battery every
3 months if it is not used for a long time.
The new brake blocks and discs feature relatively smooth surfaces, so the braking
effect will improve after you ride 100 km or brake on long downhills 3 to 5 times,
when such surfaces are roughened.
Check screws between the brake lever and the handlebar, as well as screws
between the brake clamps and frame or front fork:
The wear degree of brake blocks should be checked after you’ve ridden on normal
roads for 1,000 km, or 600 km if the road conditions are complex. The blocks
should be replaced promptly when two thirds or more are worn.
Contact a professional store and ask technicians to replenish the lubricant after
you conrm that there is no sign of oil leakage on the brakes when you feel that
they are obviously softened even though their wear degrees are still acceptable.
Contact a professional store and ask technicians to find out the cause of any
abnormal noise and come up with a solution if you notice obvious abnormal noise
during riding and the problem persists after you clean the oil on the brake blocks
and discs.
Performance of the hydraulic brakes.
The fastening performance of screws, especially those between the discs and
bottom brackets, in key parts.
The wear degree of the head parts.
The wear degree of the front hub bearings.
The wear degree of the pedal pivots.
The professional store should lubricate the internal pivots to ensure the
smoothness of pivots in front fork parts, front hub bearings, bottom bracket, and
other parts.
The wear degree of the tires.
The fastening performance of the bottom bracket torque sensor, battery, controller,
motor, display, and other electronic control parts.
i. Check if these screws maintain the same fastening performance when your e-bike reaches a
200 km riding distance
ii. Check the fastening performance at every 1,000 km after the initial 200 km.
iii. It is recommended to check the fastening performance of screws at every 600 km if you
often ride under complex road conditions
