- Be sure that the hinge locks of the seat and handlebars are locked before starting the trip.
- Check the condition of the brakes frequently and adjust when necessary. Braking range on a dry road is
13 feet and on a wet road can reach 50 feet. Keep more distance on a wet road.
- The chain is properly adjusted and should not be altered. The chain must be lubricated to prevent
accelerated weathering.
- At night, the headlight and backlight must be switched on by a switch on the control display.
- Be sure to wear appropriate clothing and do not carry objects or bags in a way that they can be caught in
the wheels or chain. To keep the rider safe - do not bring your legs to close to the chain.
- Do not ride in weather that does not allow safe riding such as rain, puddles, strong winds, snow, etc.
- When stopping, use both brakes. Don’t settle with one brake, Use both brakes together in order to
maintain stability and achieve greater control.
- Do not ride under the influence of alcohol, drugs or substances that affect the rider's alertness.
- When riding, you must hold both handles, do not perform stunts and reckless turns without examining
the area from all sides before proceeding.
- Please follow local and state regulations.
- Do not drop the bike on the ground (due to the sensitivity of the battery, motor and controller). The bike
should be placed on the kickstand carefully.
- Do not jump or climb sidewalks on the road.
- Damage to either the spokes, wheel, or tires resulting from typical cycling injuries and accelerated wear
of the battery (which may result from travel with a curved wheel) are not covered by the warranty.
Folding the Bike
- The bike can be folded for storage at home or in the trunk of the car.
- The folding time is only 10 seconds. You can get a demonstration at the point of purchase or watch a
tutorial video on our site www.GreenBikeElectric.com
Here are the pictures of the bike in a folded position and in an average car trunk:
Before You Start to Ride
Raise the seat as shown in Figure 3 and insert the battery into place and lock it.

The Electrical System is Now Ready!
• Fold the kickstand from the ground, then sit on the seat. Put one foot on the pedal and the other on the
ground.
• Now, start pedaling and the engine will go into action. There will be a faint rustle of the pass-through.
• To maintain battery life, do not use it until its end. When the battery meter flashes, turn off the power
switch and use the pedal as a regular bicycle. After recharging, you can ride again with the electric motor.
• Back Injury: The rear of the bike is not intended to carry people. Maximum load is up to 25 kg, and the
luggage should be tied with straps and tested during riding.
• Park in a safe place that is not an obstacle to vehicles or pedestrians. Place the bike on the kickstand,
disconnect the power with the main switch and pull the key out of the lock.
• The bike must be locked with a massive lock that make it difficult to steal. It is recommended to take the
battery with you.
• Charging: The battery must be charged only with the charger that supplied with the bike. A lithium
battery is only charged by a charger that designated to lithium batteries and not by other charger. The
battery must be charged with GUANZHOU ELECTRONICS CORPRATION P / N; S12.
Charging with a different charger can damage and void battery warranty.
Do not open the battery or charger for testing or repair! Bring to repair shop for testing!
• Charging takes up to 6 hours, depending on battery status. The battery can be charged both on and off
the bike.
• The charging cable must first be connected to the battery and then to the mains socket.
• When the charge indicator light is red, the battery is charging. When the charge light turns green, the
battery is full and must be disconnected from the power source. When charging, the battery must be in a
proper position so the battery won’t fall or be damaged.
• The charger becomes hot during charging. Keep it away from any flammable materials and keep the
vents unblocked
• Be sure to properly dispose of dead batteries at proper recycling plants and do not throw away in the
trash.
• Before beginning the ride, check that all the indicator lights are working and the battery is locked in
place.
• Check that the electrical contacts of the battery are always clean. Clean with a dry cloth without
moisture.
• Check tire pressure regularly (40 PSI). Poor pressure will cause overuse of the battery and shorten cycling
time.
• Do not drive in puddles. If water enters the engine, the controller or the battery house may become
damaged. Water damage will void the warranty provided by the manufacturer.
*Store the bike in a dry place. Moisture causes corrosion! Do not leave the bike in the rain. Immediately
treat the corrosion with suitable oil! Water penetration into the electrical mechanisms will void the
warranty.
• Do not put the bike in the sun especially when leaving the battery installed on the bike.
• Do not disassemble the electrical parts. Disassembling them independently will void the manufacturer's
warranty.
• It is important to lubricate the moving mechanical parts such as the wheel hinges, transmission and
gears, cable connections to the brake pads, etc. Do not lubricate the electrical parts themselves!
• Brake maintenance: The right brake is responsible for braking the rear wheel. The left brake is
responsible for braking the front wheel. Always check if the brakes are normal and are optimally tuned.
• An unintentional braking creates unnecessary and harmful resistance to the bicycle and the life of the
electrical system!
• In picture 6 you can see a stretched handle in optimal position.
In addition, you can access any authorized bicycle shop to handle the mechanical parts of the bike but not
the electrical parts.
The electrical parts can only be handled by a workshop authorized by the importer.
