EWV-A6AH26F USER'S MANUAL
4.6 BRAKING SYSTEM
The braking system is a necessary component of every bike and the key to road safety; before riding, you must understand your
braking system, and properly carry out inspection and adjustment work. It is a common misconception that if you brake hard, the
bike will stop almost right away, but this is not the case. Upon hard braking, when the wheels are suddenly jammed by the brake
rubber, the bike will skid, and it not only is dangerous but the braking distance will be lengthened. Therefore, the braking system
should be thought of only as a means to adjust the speed of the bike. The braking system typically includes a brake lever, brake (disc
brake, V brake, and many other types of brakes) and brake cable. The structure of the brake lever is as shown in this manual. The left
brake lever controls the rear brake and the right brake lever controls the front brake. The effective stroke of the brake cable is about
a half of the distance between the brake lever and the grip.
Common sense tips for use of the braking system:
If the distance between the brake shoe and the rim is too large, it can be adjusted by the brake lever or the clamp. If the brake cable
or brake shoes are seriously worn, they should be replaced right away in order to ensure road safety. When riding on rainy days, the
breaking system will be less effective, so please ensure a longer safe braking distance and reduce your speed. Do not oil the surface
of the brake disc or the brake shoes so as to avoid serious damage. A damaged brake cable is extremely dangerous and should be
replaced right away, as it is at risk of breaking.
4.7 SPEED CONTROL SYSTEM
Designed to be used in combination with physical strength, the speed control system takes into account different terrains and high
and low pressure wind conditions. The entire speed control system includes a derailleur, front and back fenders, chain plate, and
flywheel and shift cables. The number of speed change series is the number of fluted discs × the number of flywheel pieces.
For example: three pieces of chain plate × 7 flywheel pieces = 21 speed change series, and so on.
4.7.1 GEAR SHIFTS AND DERAILLEURS
(as shown)
TYPE OF GEAR SHIFT: DIAL TYPE
The gear shifts are separately positioned on both handles.
The left controls the front derailleur, the right controls the rear one.
4.7.2 ADJUSTING THE GEAR SHIFTS
The derailleur is divided into front derailleur and back derailleur.
The gear shifts control the front derailleur and back derailleur. If the shift cables are loose or too tight,
the speed controller doesn't work properly or the chain falls off, the H, L bolts must be adjusted.
H bolt: When the chain speed changes to the biggest fluted disc, the chain will fall off,
and the H bolt will be locked. But if it is too tight, the chain can't climb to the biggest fluted disc.
L bolt: When the chain is toward the inside fluted disc and the chain falls off, the L bolt is locked.
But if it is too tight, the speed can't decrease. Therefore, you must adjust the H, L bolt to a suitable position.
4.7.3 ADJUSTING THE CHAIN
If the chain is too long, it will skip between gears, which means it is not correctly , and at this time the chain has not meshed with the
cog correctly, thus affecting the cycling performance; if this occurs, the chain should be adjusted right away. To set the correct chain
tension: Adjust the front derailleur to the lowest shift (the smallest tooth of the chain ring) and also adjust the back fender to the
lowest shift (the smallest tooth of the flywheel) to check whether the chain slack is more than 15 mm (as shown). If it is more than 15 mm,
the chain is too long. Visit your supplier to have the chain shortened to ensure your bike's optimal performance.
Common sense tips for use of speed control system:
Do not reverse while changing speed, as this could lead
to failure and cause the chain to fall off.
As much as possible, do not change gears rapidly.
You should increase the speed gradually by moving up one gear
at a time. If the electric bike is idle for a long time, the chain will
switch to the minimum pulley tooth and the smallest flywheel,
so as to avoid wearing out the mechanical flexibility.
The chain, fluted disc, flywheel, derailleur should be kept clean
and lubricated (oiled appropriately).
