1) Do not operate the e-bike before reading this user manual thoroughly. The manufacturer will not be
held responsible for any damage or accident due to improper use.
2) For your safety and others please follow the traffic regulations. This bicycle is not suitable for children
under thirteen and the disabled. This e-bike is not recommended for competition, stunts or off-road riding.
3) Do not lubricate the brakes.
4) The braking length of a dry state surface/road is 4 meters at 25km/h, while 15 meters in wet state. So,
move slowly, keep a safe distance from other vehicles/objects around you and brake in advance where
necessary while riding downhill and in rain, snow & wet road.
5) To ensure your safety please use helmets, check brakes & tyres, handlebars and rims before riding.
6) Maximum rider weight: 115 Kg.
Maximum carrier weight: 15 Kg.
7) Improper use could cause harm, please check the connection of the frame, stem and suspension
periodically. Every mechanical part has friction and pressure. Different materials and parts have different
frictions and pressures. If a mechanical part has exceeded its service life, resultant damage could hurt the
user.
8) Do not ride in water where the depth exceeds the controller. The motor or directly flush water to
electrical components.
9) Avoid prolonged exposure to the sun or rain and exposure to humid places. Aggressive gases may
cause parts to corrode or electrical parts to fail. This can lead to malfunctioning or accidents.
10) This product contains advanced electrical components built in to the structure. Please do not
disassemble or modify any part of it.
11) The performance and mileage of the unit will be varied depending on the battery condition,
temperature, terrain, wind speed, tyre pressure, rider weight and the maintenance, etc. To get the best
mileage we propose that:
(1). Ride for 3-5m in power mode when starting.
(2). Try to reduce frequent braking or restarts.
(3). Ride in PAS mode while on uneven road conditions, uphill or headwind.
(4). Avoid carrying people or overloading
(5). Check the tyres before riding to ensure they have the correct pressure.
User Security
Regular check’s for safety before riding
1) Check if the handlebar stem and saddle post are safely inserted. Take note of the maximum height
markings (MIN. INSERTION) on the tube.
2) Check the brake shoes for excess wear. If there is wear, you should replace them before riding.
3) Check if the nuts on the front and rear axis are securely fixed.
4) Check the pedals and other fixtures for any signs of damage. Check if the rotary parts move freely.
5) Check the tyre pressure in accordance with the markings and check for ample treads on the tyre. If they
are excessively worn replace them immediately.
6) Make sure that you know how to operate the e-bike and clearly know all the traffic regulations.
7) Check if the brake and the power function are working well.
(1). Stand the bike on the kickstand, switch to the electric mode and then slowly turn the throttle. If the
motor does not work, then the kickstand can cut the power efficiently.
(2). Close the kickstand, switch to the electric mode and then apply the brake. If the motor does not work,
then the brake can cut the power efficiently.
9) Check if the grip throttle functions well. Check if it goes back into place immediately after releasing it.
10) Check all electrical connections and mechanical parts are securely locked, check all cables, connector
plugs and sockets must be dry and undamaged.

General Maintenance Remarks
Cleaning and Maintenance
Regular maintenance guarantees you a longer durability and road worthy state of your bike.
Maintenance includes cleaning, lubricating and ride setting adjustments. Regular maintenance work
is required to sustain a warranty claim. This applies to special corrosion (surface rust) and other
damages, which by non-observance, would not be undertaken by us. Thus, please read through the
following section thoroughly.
Lubrication
Chain
The chain must be regularly (especially after riding in the rain) lubricated with a standard chain-caring product.
Physical stretching of the chain requires checking procedures to be carried out to ensure that the tension is
adequate. Examine the chain tension by positioning the bike on its kickstand and test whether the chain, while
being pushed upwards or downwards has a maximum gap of 10-15 mm in between. If this is not the case
please proceed to the following steps:
!) Loosen the axle nuts on both sides of the wheel and the brake counter - bracket (for the back pedalling
brake) on the left side of the rear - end stay. When a gearbox removal is required please see the
manufacturer’s instruction manual
.
2) Subsequently, adjust the chain’s tension by turning the tension screw nuts on both the left and the right
sides.
3)Before tightening of the axle nuts, check whether the wheel stands in the centre and adjust if needed.
4) Tightly screw the axle nuts and the tension screw nuts. (Tightening Torgue not less than 30N-M)
5) Recheck the chain tension
An over-tightened chain can cause pops during riding.

Adjust the derailleur
Adjust the Fine-tuning nut or screw when the derailleur makes some abnormal sound. The way to adjust the
brake of the bike is the same as adjusting the gears. The most important thing is effective braking, releasing
of the brake pads and the power brake function work well together. Friction between road and tyre is reduced
when raining, so every rider should brake gently in order to avoid danger. Please follow the several bits of
advice given, every screw and nut should be tightened properly to make sure the wheel is running freely with
no resistance. Brakes
• Always make sure that the front and rear brakes are working correctly
before you ride the bicycle.
• Before riding the bicycle, check that the pad thicknesses are 0.5 mm or
more.
• If noise occurs when the brakes are operated, it may indicate that the
brake pads have worn down to their usage limit. After checking that the
brake system has cooled down sufficiently, check the brake pad
thicknesses. Replace the brake pads if the pad wear indicators are visible.
• Be careful not to allow any oil or grease to get onto the rotor and brake
pads, otherwise the brakes may not work correctly.
• If any oil or grease do get on the pads, you should replace the pads. If
any oil or grease gets on the rotor, you should clean the rotor. If this is not
done, the brakes may not work correctly.
• Check the brake cable for rust and fraying, and replace the cable immediately if any such
problems are found. If this is not done, the brakes may not work correctly.
• The required braking distance will be longer during wet weather.
Reduce your speed and apply the brakes early and gently.
• It is important to completely understand the operation of your bicycle's brake system.
Improper use of your bicycle's brake system may result in a loss of control or an
accident, which could lead to severe injury. Because each bicycle may handle differently,
be sure to learn the proper braking technique (including brake lever pressure and bicycle
control characteristics) and operation of your bicycle. This can be done by consulting
your professional bicycle dealer and the bicycle's owners manual, and by practicing your
riding and braking technique. Warranty
