IV. Adjustment Instructions
A. Adjustment of Front and Rear Brake System:
Note: The adjustment method of the front and rear brakes is the same.
1. Adjust the rear integrated disc brake by adjusting its upper and lower nuts to make a space of 1.5-3mm
between the disc brake and brake calliper.
2. Adjust the height of the disc brake, and then tighten the nuts.
B. Front Integrated Disc Brake:
Note: If the distance is deviated, use the C screw to adjust, and then tighten the nut.
1. Adjust the rear integrated disc brake by adjusting its upper and lower nuts to make a space of 1.5-3mm
between the disc brake and brake calliper.
2. Adjust the height of the disc brake, and then tighten the nuts.
Tips:
• Rotate the Adjusting nut to rotate the Adjusting nut forward, the brake becomes tight, otherwise it
becomes loose.
• When adjusting, hold the brake handle at the same time, so that when the position of the brake
handle is 1/3 of the total stroke, the brake rubber block can be tightly attached to the brake drum.

C. Disc Brake:
There is enough clearance between the disc brake and the brake pad
(there is no interference between the brake disc and the brake skin
when rotating, and the best braking effect is appropriate).
Key points of disc brake adjustment:
• Adjust the nut, and lengthen about brake cable.
• Check whether the brake handle has been adjusted to the
appropriate tightness.
• Test ride to ensure effective and normal braking.
D. Belt Adjustment:
1. Loosen the fastening nut A on the side of the left and right movable claws of the rear axle, and
adjust the inner nut B in the middle of the movable claws to make the belt tight enough for sliding
without abnormal noise as shown in the image below;
2. The centre surface of the rear wheel is basically kept on the centre surface of the frame, and at the
same time, tighten the fastening nuts A on the left and right sides of the rear axle with movable
claws.
E. Front Wheel Disassembly:
1. Loosen the left and rear fastening thread of the front axle, remove the nut, remove the front
axle, and remove the front wheel.
2. 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).
F. Rear Wheel Disassembly:
Note: Do not touch the handlebar, head cover, toolbox parts.
Pull the motor cable off the connector, turn the car body over rotate the rear axle nut, rear brake
positioning nut and brake cable in the counterclockwise direction, unpack the chain joint, and

indicated on the display.
2. Check Of Brake Device:
• 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 the support of the whole vehicle.
