Precautions before riding

Dear users, for your safety and to prevent safety accidents, please do the following checks before riding. If there is any abnormality，please repair it in time or find a professional repair!

• Check whether the power supply circuit, lighting circuit and device are damaged; Turn on the power supply, operate the lighting switch, check whether the headlights and taillights are on, and whether the brightness of the headlights and taillights is normal;
• Check the front and rear brake handlebars respectively to check whether the stop lamp is on and whether the motor is powered off;
• Operate steering lamp switch to check whether the steering indicator and turn signal are working properly.
• Check whether the front and rear brakes can work normally; Check the braking effect of the front and rear brakes to ensure that the brakes are normal and effective;
• Confirm whether the power-off switch is normal when the rear wheels are off the ground with double support of the whole vehicle;
• Please check the fastening status of each axle to ensure that the front and rear axles and handlebars are fastened reliably.
• Shake the handlebar up, down , front, back, left and right to check whether it is loose or pongee;
• Shake left and right front and back wheels to check whether there is looseness; whether the rotating wheel is too tight or stuck.
• Check whether the tire pressure is normal. Judge whether the air pressure is appropriate according to the depression of the ground part of the tire. When the air pressure is abnormal, use the tire pressure measuring instrument to check and adjust it to the normal air pressure;
• whether the tire has cracks or abnormal wear;
• Whether the tire is embedded with nails, stones and glass;
• When the tire is used to the tread wear mark, the tire should be replaced.
• Check whether the reflector is missing. If it is found missing, contact the after-sales service immediately to reassemble the reflector of the same specification and model, and the installation position should be consistent with the original bicycle .Please do not change the position, modify, disassemble, etc. privately.
• Before each use, check that the function of the reflector is normal and the surface of the reflector is kept clean.
• The Reflector device cannot be blocked by luggage, children chair, clothes and other objects, otherwise it will cause potential safety hazards.
• Check whether the license plate is installed firmly, whether the number is clear, whether there is any damage or pollution, and if there is any should, reinforce, clean or replace it in time.
• Before each ride, please make sure that the following items: whether the frame lock，vertical tube lock, seat tube locking fastener are locked, whether the brake system is normal, and the tires are full of gas to ensure riding safety!

Adjustment methods of each part

1. The rear integrated disc brake(see figure 1); Adjust the upper and lower nuts of the disc brake to make the spacing between disc brake and brake caliper 1.5-3mm, adjust the height of disc brake, and then tighten the nuts.
2.  Front integrated disc brake (see figure 2): Adjust the A and B nuts of the disc brake and adjust the height of the disc brake so that the distance between the disc brake and the caliper is 1.5-3mm. If the distance is deviated, use the C screw to adjust, and then tighten the nut.
3. Disc brake: (see Figure 7 and 8) Key points of disc brake adjustment: there is enough clearance between disc brake and brake pad (there is no interference between the brake disc and the brake skin when rotating, and the best braking effect is appropriate) adjust the nut, lengthen about brake cable, check whether the brake handle has been adjusted to the appropriate tightness; Then test ride to ensure effective and normal braking.
4. chain so that the sag in the middle of the chain is 10-15mm.At this time, the tightness of the chain should be suitable for go slick, no abnormal sound. Keep the center surface of the rear wheel basically in the center surface of the frame, and tighten the rear axle left and right fastening nuts. (Recommended torque is not less than 30N.m) Front wheel disassembly (see Figure 5) Loosen the left and rear fastening thread of the front axle, remove the nut, remove the front axle, and remove the front wheel. When assembling, align the center hole of the front wheel with the double arm hole of the hydraulic front fork, penetrate the front axle into the hole, and tighten the left and right fastening nuts of the front axle clock wise. After installation, rotate the front wheel, and there shall be no stuck or loose phenomenon. (The recommended torque is not less than 18N. m)IV.Rear wheel disassembly (see Figure 6 .Pull the motor cable off the connector, turn the car body over(note: Do not touch the handlebar, head cover, toolbox parts), rotate the rear axle nut, rear brake positioning nut and brake cable in the counterclockwise direction, unpack the chain joint, and then remove the rear wheel in the direction of the opening.

Maintenance and Repair

Daily maintenance:

1. The vehicle should be kept clean and clean, and the vehicle should be wiped with dry cloth in time after being drenched to avoid rusting of parts and short circuit of electrical components.
2. Always check the air storage capacity of the tire to keep it in normal use.
3. The main transmission parts such as front axle, a roar axle, conter axle, front fork, Flywheel and electric hub should be checked and adjusted frequently to keep the transmission parts flexible without impact sound and noise; Check the screws and nuts of the whole car, if it is found that it is loose, it should be tightened in time to prevent the parts from being worn out or causing greater damage and fracture due to looseness.
4. The braking part should be checked and adjusted frequently to make it in a flexible state, for example, the gap between the brake rubber and the gate core should not be too large.
5. Always check whether the operating parts and cable are flexible, and ensure that there is no stagnation, no stagnation, and properly drip lubricating oil from one end of the hose slowly, and pull the wire rope at the same time, feel that the wire rope slides lightly in the hose.
6. Electric bicycle moving parts should be often injected with a small amount of lubricating oil to reduce wear and keep riding light, as shown in the following table:

/once every year
Front and rear wheels| Check the wheel swing, spoke tension, spokes, mother spoke for damage; Adjust the wheel| The first month/year after the first new car
brake cable| If there is a steel wire at the root of the rolling head, replace the new brake line.| Once every month
brake handle| If there is a steel wire at the root of the rolling head, replace the new brake line.| Once every three months
Chain| Check whether the pin shaft is loose or bulging, and whether the extension of the chain is too large.| Once every six months
Front and rear nut, handlebar core screw, saddle clamping screw| Check for looseness| Once every six months

Correct use and maintenance methods of motor, controller and battery:

1. The motor should be kept clean, no foreign matter, corrosive liquid, gas, etc. should enter the motor, and the motor Shell should not be knocked and baked to avoid damage to the motor.
2.  All wires should avoid friction and contact with sharp metal, and the wires should be tied firmly with the frame.
3. The controller is a high-tech intelligent computer memory program password. If the user opens the repair by himself, the components will be easily damaged. If the controller fails, please go to the service department to repair it.
4. This battery is a special battery for electric bicycles. When the electric bicycle is not used for a long time, the battery should be stored after sufficient electricity, and the electric energy should be replenished regularly to avoid battery vulcanization caused by long-term under power.
5. The battery cannot be near open flame or high temperature heat source, and the battery cannot be thrown into the fire. Direct exposure to the sun is strictly prohibited in hot and hot weather
