BRAKES
ONYX has a hydraulic disk brake system installed on both wheels, front and rear, to control the braking of the bicycle. The
system has an electrical cut-off function, an important safety feature of all e-JOE bikes. It disengages the motor when the
brake levers are squeezed. Therefore, it is critical to make sure the brake system works properly.
●
Test your brakes every time before using the bicycle and remember the bicycle will not stop as quickly in wet or icy
conditions as it would on a dry road.
●
Remember which wheel is controlled by which brake. Do not brake too strongly or abruptly, as it will make it easier
for you to fall. Incline your body backward to reduce the influence of inertia.
●
The brake system requires regular cleaning, maintenance, and adjustment. Have your brakes inspected and
serviced regularly by an experienced mechanic (every six months to a year should be sufficient for occasional
cyclists). Take your bike in more often if you ride or use brakes frequently.
●
The brake system includes brake pads which gradually wear down due to normal use. When the brake pads wear
out, replace them as soon as possible.
●
With use over time, brake fluid will become contaminated with dirt and moisture and should be replaced. It is
recommended to use mineral oil for brake fluid replacement. For additional information, follow the brakes
manufacturer’s instructions.
●
DO NOT ride the bike if the brake oil is leaking as the system may suddenly lose braking power.
●
The bike should not be stored or turned upside down, as air may enter the brake lines. If the bike has been upside
down, allow it to sit several minutes before use, and test the levers by pulling with force.
●
Over time disc brakes lose some of their effectiveness. This leads to longer response times, less efficient braking,
and less bike control. If you start experiencing such issues, hear a squeaking noise when braking, lack stopping
power, refrain from using the bike and bring it to a local bike shop for inspection & service.
DRIVETRAIN & GEARS
The drivetrain of the bicycle consists of all parts that you use to push or pull the bike along. The key components are the
pedals, cranks, chain, freewheel, gear shifter, and rear derailleur.
Gears are there to enable you to maintain a comfortable pedaling speed (or cadence) regardless of the gradient or terrain,
something that single gear is not capable of. ONYX comes with the seven-gear system. To change the gears while riding,
press + or – of the shifter on the right side of the handlebar until you reach your desired gear. The gears are switched by the
rear derailleur located on the right side of the rear wheel. The derailleur moves the chain up or down the freewheel setting it
to the desired gear.
●
The gear setting is displayed on the shifter. The higher the gear, the more resistance is given when pedaling.
●
The combination of pedaling and gear affects the battery range when riding with pedal-assist. If you are riding uphill
or in the areas where it becomes difficult to pedal, shift to a lower gear. If you find that you are moving faster than
you can comfortably pedal, try moving to a higher gear. This will help conserve battery power and achieve
comfortable pedaling.
●
It is easier to start riding if the bike is set to a lower gear.
●
If you experience “skipping” of gears, noisy switching, bring the bike to an experienced mechanic for adjustment.
●
Keeping your derailleur, chain, and freewheel clean, lubricated, and moving freely will expand their service life and
avoid costly repairs.
●
If you need to service the pedals, follow instructions on page 8 for their removal and installation.
