*Before your first operation,
please read the user manual carefully!
1. Note
Before your first ride, it is important for you to know your new e-bike well, so that you can
get the best performance, comfort, enjoyment and safety from it during your ride. To
understand the new bicycle and the correct operation, you should first read the manual
carefully.
Second, it is significant to take your first ride under a safe and controlled circumstance, like
staying away from cars, obstacles and other cyclists.
Third, bicycles are vehicles with certain risks. Please follow the traffic rules during cycling.
It's better to learn the local traffic rules about riding an e-bike on public roads before your
first ride in case you violate the regulations. For your own safety, never forget to put on a
qualified helmet before you get on the e-bike.
Fourth, the electric bike is supplied without basic mandatory equipment, which may vary
from place to place. Therefore, if you intend to use the e-bike on public roads, it's necessary
to equip the bike with the basic mandatory equipment, in accordance with the relevant laws
and regulations.
In addition, this product is designed for your personal use. Do not use it for commercial or
other purposes.
Last, keep this manual safe for reference.
2. Warning
Before each charge, check the charger, cable and plug. If there is any damage, do not use
the charger.
Before riding, check the tire pressure and check whether the wheels and handlebar are
installed correctly and tightly.
Before riding, check whether the headlights are securely fastened in the correct position,
clean and not covered by anything. Damaged reflectors must be replaced.
Besides, if the seat post in the seat tube is not inserted deep enough to reach the minimum
insertion mark, the seat post may break. Check whether it is inserted deeper than the
minimum insertion depth. When braking on a wet road, the braking distance is usually
longer than on a dry road. Therefore, brake earlier for a safer stop.
When you have to brake urgently, please hit the right hand brake first to stop the rear wheel,
and then hit the left hand brake, especially when you brake at a high speed. If the front
wheel stops suddenly while the rear wheel is still cycling at a high speed, you may fall over
and get hurt. So please ride it carefully.
Furthermore, avoid puddles, wet mud, swamps, water, snow or ice. Try not to use the e-bike
on a rainy, stormy or snowy day. If the bicycle's electric parts (control unit, engine and
battery) get damp, wet or soaked, it will cause irreversible damage, or even a battery
explosion.
This product can only be used by one adult at a time. Do not carry any extra passengers.
This vehicle is not a toy. Same as other vehicles, it is possible to fall, crash or encounter
other danger¬ous situations. Please don't offer your e-bike to anyone that doesn't know how
to use it correctly. If you let anyone else ride your bike, it will be your responsibility to ensure
that all riders understand all warnings, cautions, instructions and safety precautions, and to
ensure that they are able to use this product safely and responsibly and protect themselves
and others from injury.
