2. Mode 2: Medium speed, the limited speed is 12.4mph.
3. Mode 3: High speed, the limited speed is 18.6mph.

How to switch speed modes:

Press the M button on the display to switch speed modes.

Three riding modes:

1. E-Bike
2. Pedal Assistant Bike
3. Bike

It is bike mode when power off. It is assistant mode when power on, but assistance performs well just when the motor speed is lower than manual speed, or performs well when climbing; this is normal. It is E-Bike mode when power on too, you do not need manual pedalling.

4. Instructions for using Folding Pedals

Installation:

The pedal shaft core "L" and "R" correspond to the left and right sides of the crank. The L shaft core requires counterclockwise installation, and the R shaft needs to be installed clockwise. Use a 15mm open-end wrench to tighten it. If the crank is made of aluminum alloy, the pedal shaft must be coated with thread glue before it can be screwed into the crank.

Steps to install the foot pedal:

1. Take out the pedal, L is the left pedal, R is the right pedal.
2. Align the crank threaded hole with the central axis of the pedal.
3. Use a wrench to clamp the central shaft of the pedal and tighten it, turn the central shaft of the left pedal counterclockwise and tighten the central shaft of the right pedal clockwise.

Use:

When the pedal needs to be folded, first stop the bicycle and push the pedals 30mm inward with the palm of your hand, and then fold it up or down to complete the folding. If you need to open it, push the pedal shell out with your hands or feet to open it.

Note:

When the pedal needs to be folded, if you push the pedal shell inward with your hands, do not grab your fingers on the pedal shell to prevent your fingers from being caught and injured.

Install the saddle:

Loosen the quick-release handle of the middle tube, insert the saddle tube into the body of the middle tube and adjust the saddle height to the appropriate height (should be about 1 inch higher than the rider's crotch). Then lock the quick-release handle. If the saddle is too loose after the handle is tightened, first loosen the handle, and then adjust the tightness through the adjusting nut on the right, and then close the handle. We advise inserting the seat tube cover the min insertion line for safe.

You have to practice riding the ebike in a safe ground before riding outdoors. Know your cycling environment well, and avoid being disturbed by cars, pedestrians, pets or other obstacles. Have a skilled assistant who is familiar with riding e-Bike and knows about all precautions and riding methods in this user manual. Dry and brake it in a safe place after cleaning the bike, for moisture makes brake react slowly. Increase the distance between others in bad weather.

13. Bike Maintenance and Precautions

1. Precautions about Wet Weather:

Please avoid storing the product in a wet environment for a long time to avoid oxidation of iron metal parts and increase the service life of the product.

2. For Your Driving Safety, But Also to Keep Your Bike in the Best Condition, Please Regular Maintenance and Cleaning:

Daily maintenance: use a dry towel to wipe the water and dust on the bike after each ride. Spray appropriate antirust and lubricating oil on the chain and pinion to ensure the normal operation of the transmission system.

Brake maintenance: After a period of riding or after the brakes have been used for some time, there will be some wear and tear on the brake ring plates. If the brake is not tight, the brake handle nut can be turned to improve the brake stroke appropriately. If this method still fails to improve, please send to a professional electric vehicle repair shop for maintenance.

Maintenance of control cable: check the normal use of related electrical appliances before use.

1. Check the throttle. Suspend the rear wheel and gently twist the speed regulating throttle to confirm whether the motor can work normally.

Bearing adjustment: pinion regular maintenance and lubrication, no other bearing adjustment.

Wheel adjustment: please check the tire pressure before use. When inflating, keep the tire and hub concentric as far as possible, and then inflate slowly, so that the wheel and tire slowly complete chimeric state. If you encounter a flat tire, please send it to a professional electric vehicle repair store for maintenance.

Handlebar adjustment: loosen the quick-release handle of the handlebar, adjust the grip to the most comfortable state and then lock the quick-release handle.
