To improve riding enjoyment and pedelec efficiency, the intelligent pedal speed
sensor is used, which responds to power take-off control of pedal speed sensor
synchronously by a central processing unit with artificial intelligence. It means that
depending on change of terrain and riding gear, pedelec system will output relevant
auxiliary power automatically and synchronously, achieving the riding enjoyment of the
rider integrating into E-bike. So it’s not only a 100% special bike, but also an eco-hybrid
two-wheel-drive bike by activating pedelec system. People can not only regard it as a
general recreational bike simply, but also use pedelec system to make the challenging
long-distance riding or slope terrain become much easier and more comfortable. One bike

V. Maintenance and care
◆Safekeeping and care
Emphasis of safekeeping and care
Check whether bike body is cracked. Any crack means potential danger and will give rise
to accident. If repair is not conducted or relevant fittings are not replaced in time, there
will be severer danger. Once bike body is cracked, the crack will become larger in a short
time. Rustiness or discoloration may hint the occurring of cracks. If you find a crack,
please replace relevant fittings.
1. Check and observe any rusty position carefully to confirm whether there’s any crack.
Rustiness will quicken the damage of bike body or parts and large cracks.
2. Clean your bike, lubricate relevant fittings and make your bike away from any
corrosive things such as salt.
3. Do not polish, drill or engrave mark on the surface of bike body. Large scratches and
boreholes will cause cracks. Attention should be often paid to these positions or
replace with new fittings.
A bike that’s properly maintained will not produce abnormal sound while riding. Some
cracks (Especially larger cracks) will produce abnormal sound when you ride the bike.
Such abnormal sound is the signal of warning of danger. Attention should be paid to
the source of abnormal sound (even if it’s not caused by cracks), namely eliminate the
cause of abnormal sound as soon as possible.
Caution!
If bike is damaged or needs adjustment, please contact seller for assistance and do
not repair the bike by yourself. Repair and maintenance of bike needs special
knowledge and tools. Non-professional adjustment or repair may damage the bike or
cause accident and heavy casualties.
z If you want to master the main repair techniques:
1. Ask your distributor to provide introduction data of installation and maintenance
of parts of bike or contact manufacturers of parts.
2. Ask your distributor to recommend the books relating to repair of bike.
3. Consult your distributor on the courses relating to repair of bike.
