Bike Usage
Before Riding
During riding
After riding
Before riding the bike on the open road, try all the settings on the electric bike, and get
used to various results in a safe and controllable environment.
Please check the power circuit, lighting circuit, and test the brake system before cycling.
Always check the tire pressure before starting to ride, and make sure that the tire is inflated
to a pressure within the specified range.
In order to ensure the safety of riding, please check regularly for loose parts or screws.
The places that need to be checked include but not limited to the seat tube, wheels,
handlebars and pedals.
If necessary, please confirm whether the battery capacity can meet you riding demand.
If the pressure is too low, the wheel may be damaged, or the inner tube may be
squeezed, causing the tire to leak air.
If the pressure exceeds the recommended maximum value, the tire may blow
out of the rim, which may damage the bicycle and cause injury to the cyclist and
nearby people.
Please wear helmets and riding gear that meet the requirements in accordance with
regulations.
Avoid traveling in severe weather such as heavy rain.
Carry people or objects in accordance with the requirements of laws and regulations,
and the load of the entire bike should not exceed 130kg.
Obey the traffic rules.

Shifting Recommendations
Brake Adjustment
In order to increase the range, we recommend shifting according to the speed.
For starting and low-speed riding, it is best to use a low-speed gear.
At higher speeds, a higher gear should be selected.
If the brake is not sensitive, loosen the
anchor bolt of the brake cable to shorten
the brake distance of the brake cable and
then tighten the bolt. Or, lengthen the
distance of the brake cable when the brake
is too sensitive.
If the rotor always rubs against the
brake pad or the gap is too large, loose
the two centering adjustment screws,
but do not remove them. Slowly rotate
the wheel and check the space between
the rotor and the brake pad; adjust the
position of the brake pad and the rotor.
Centering the rotor and the pads to
avoid friction. After the adjustment is
complete, tighten the screws.
Ensure that the brake cables are properly inserted into the brake levers before aligning a
mechanical disc brake. If the disc rotor is bent or damaged, replace the rotor first.
