SAFETY

You should wear an approved bicycle helmet every time you ride 
a bicycle, regardless of the legal requirement to do so. You should 
comply with local law when riding your Sinch E-Bike.

Read and understand all sections of this entire manual before operating the bike for the first 
time. There are important safety warnings throughout the manual that must be followed
to prevent dangerous situations, accidents, damage to the bike, damage to property, injury, 
or death. 

Users must follow the instructions and warnings contained in this manual for safety. Do not 
attempt to operate your bike from Aventon Bikes until you have adequate knowledge of
its control and operation. Damage caused by failing to follow instructions is not covered
under warranty and could result in serious injury or death. Contact Aventon Bikes if you have 
any questions about assembly or operation. 

Users must become accustomed to the bike’s power control system before operating. The
pedal assistance feature is also a powerful option and users should fully research and
understand how to operate it before first use. Not taking the time and care to familiarize
yourself and practice the operation of the power system on your bike from Aventon Bikes can 
lead to damage, serious injury, or death.

Derailleur

On the right side of handlebar, next to the brake lever, you can see two levers 
with 7-1 gears.  Those are derailleur levers. By pressing those levers, you can 
make the chain move to different gears to change your riding experience
