Assembling Instruction

Front Wheel Installation
CAUTION: Your Electric bike is equipped with a front disk brake. Be careful not to damage the disk, caliper, or brake pads when reinserting the disk into the caliper. Never activate a disk brake’s control lever unless the disk is correctly inserted in the caliper.

  1. Carefully take your bike out of the carton and gently rest it in place with the kickstand down(Figure.1-1).
  2. Remove all of the inside cardboard protection and bubble wrap on the bike.
  3. Please locate and set aside the kit box containing the battery charger, pedals, tool kit, etc.
  4. Remove the rubber pad and metal block from the front wheel and front fork(Figure.1-2)
  5. The fork is curved, please make sure the concave of the fork facing forward(Figure.1-3)
  6. With the steering fork facing forward, insert the front wheel between the fork blades so that the axle seats firmly at the top of the fork dropouts. (Figure.1-4)
  7. While pushing the wheel firmly to the top of the slots in the fork dropouts, and at the same time centering the wheel rim in the fork.
  8. Use the Allen Wrench to tighten the nut of the quick release(Figure. 1-5). Note: The small spring heads face the center and one on each side of the wheel.

Handle Bar, Display, and Front Reflector Installation

  1. Lose the bolt on top of the stem, then Rotate the stem through 90degrees(Figure.2-1)
  2. Unscrew the 4 screws in front of the stem with 5mm hexagonal spanner, place the handlebar on the stem, tighten the 4 screws slightly and position the handlebars to your desired comfort level, then tighten four bolts in turn until full tightened (Figure. 2-2)
    Please Note: Before installing the handlebar, please pay attention to the wires harness that connects to it, please make sure the wire harness are not twined together. (Figure.
  3. Once the handlebars are aligned and the top bolt is slightly secured, tighten the top bolt with a 5mm hexagonal spanner firmly (Figure. 2-4). After tightening the top bolt, tighten the two side bolts on the stem with a 6mm hexagonal spanner firmly (Figure. 2-5). After all three bolts have securely fastened, make sure there is no play in the headset.
  4. Unscrew the 2 screws on the display, then install the display on the center of the handlebar(Figure 2-6); unscrew the bolt on the front of the fork, then install the front reflector.

Do not over-tighten the stem bolt. Over tightening the stem bolt can damage the steering system and cause loss of control.

Seat Post Installation

  1. Please pay attention to the vertical lines on the seat post,it is the minimum insert line or safety line,please make sure the post is installed into the frame deeper than the minimum insertion line.it is at the bottom of the seat post(Figure. 3-1)Warning: It could break the seat tube during riding if the seat post does not installing correctly.It is not covered by warranty.
  2. Un-clamp the clamp on the seat tube,insert the seat post into the seat tube,adjusting the seat to a comfortable height,tighten the tension adjusting nut,then press the clamp lever inward toward the seat tube(Figure. 3-2).

Please Note: If necessary, tighten the clamp by twisting the clamp handle clockwise while in the un-clamped position. Then, fold the handle in toward the seat post. This should require a fair amount of force to ensure the seat post is held tight. If necessary, the clamp can be further tightened with a 5 mm Allen wrench while in the clamped position.

Pedals Installation

  1. Identify left vs right pedal
    There is a “L” or “R” stamped into the axle (threaded part that looks like a screw) (Figure. 4-1) Please Note: They are not the same!! Apply a small amount of grease if possible
  2. Install the left hand pedal firstly
    You will have to screw it in counter-clockwise because the threading is the reverse of a normal screw.Do this by slowly pedaling the cranks backwards.If the pedal feels stiff stop and then re-try, it should feel like a smooth motion.Do not use the wrench until you are ready to tighten it for the final few turns. Tighten it down until you can’t anymore.(Figure. 4-2)
    Please Note: Hand tight is not sufficient. Use a tool. If after riding,the threads on your crank is stripped.you have not followed these instructions. Your crank needs replacing (this is NOT covered by warranty).
  3. Install the right hand pedal
    this one threads in clockwise, like a normal screw. Follow the same principals as discussed in step 2 for the left pedal.(Figure. 4-3)
  4. Wipe off any excess grease from around the crank.

Battery And Charger Care

The charger will charge a fully depleted battery in 6—8 hours. The indicator light on
the charger will be red when the battery is charging and will turn green when fully charged.
Avoid subjecting the battery to high temperatures, such as directly under the
sun, for prolonged periods of time.
Recharge the battery before it becomes completely discharged. Completely discharging will reduce the number of recharging cycles during the battery’s life and limit the capacity. Never store the battery in a discharged state. After much use, your battery’s charge holding capacity will decrease. If you find that your battery does not hold a sufficient charge, you should contact us to order a replacement.
If the battery will not be used for an extended period of time, charge it fully and recharge it every 2 months. Store it in a cool, dry place. Your battery is engineered with precision for high capacity and a long, useful life. Do not use it to power other electrical devices. Improper use of the battery will damage the battery and shorten its useful life and may cause ire or an explosion. If you experience unusual sounds or odors coming from the charger or the battery, unplug the charger immediately and contact customer service.

Recharge the battery after every use.

  • Do not disassemble or alter the battery or battery charger.
  • Do not place the battery near fire or corrosive substances.
  • Do not allow any liquids on or inside the battery/charger.
  • Do not expose the battery/charger to extreme weather conditions.
  • Do not operate the battery/charger if damaged.
  • Recharge the battery only with a charger specified by the manufacturer.
  • Do not use the battery/charger for any use other than its intended purpose.
  • Only use the battery/charger on approved products.

Please instruct your children to keep away from the charging place.


Having an electric bike that breaks down or isn’t running smoothly is a real pain. Here are few simple things you can do to avoid this and keep it running smoother for longer.
Electric bikes are bicycles that have additional technology to provide pedal assistance. Because they tend to get used so much more, and at greater average speeds, maintenance is a critical factor in keeping them running smoothly.
You don’t need to have a fancy workshop, do these few simple things:
Bicycle maintenance
Regularly check the significant touchpoint bolts for tightness – handlebars, seat rails, wheels etc. If any of these come off while riding,it can be dangerous! Riding with loose bolts can be an expensive and inconvenient repair.
Lube your chain regularly
Check tire pressures at least once a week. Pump up to the recommended pressures if needed.
Clean your bike with a regular hose and/or bucket & brush. Avoid high-pressure water
systems as you don’t want to get water in the electrics!
Wiring. Be careful not to knock your wiring, particularly on things such as lights, motor cables near wheels, sensor cables etc
Batteries. See our article on battery care and safety. Also, take care of sliding your battery in and out, so you don’t bend any battery plate nodes.
The next best thing you can do for your bike is to get it serviced regularly by a skilled mechanic -preferably one with experience working on electric bikes! Find or avoid problems before they happen.
There is very little to do in terms of electrics maintenance however the main thing is to take care! Particularly when you are moving your bike in and out of cars, stairs or tricky storage places. Prolonged exposure to UV Rays, Rain, and the Elements May Damage the Enclosure Materials, Store Indoors When Not in Use.


Always wear an approved helmet while riding your bike and follow the helmet manufacturer’s instructions for it, use and care of your helmet. It is your responsibility to familiarize yourself with the laws of where you ride your Bike and to comply with all applicable laws.

Mechanical Safety Check:

Check the condition of your Bike before every ride. Make sure no nuts, bolts or fixing are loose, with particular attention to the axle nuts and handlebar stem. Make sure the tires are correctly inflated with the recommended air pressure that is located on the side wall of every tire. Check the brakes for proper operation. You must take your bike in to be serviced and checked by a qualified bike mechanic before 100 miles (161 kilometers) of riding. This is a standard good practice for any new bike as cables will stretch and components will “bed in”. The service must include spoke tension for both front and rearwheels.
Your First Ride:
When you buckle on your helmet and go for your first ride, be sure to pick an area away from cars, other cyclists, obstacles or other hazards in order to become familiar with the controls, features and performance of your new Bike.
Additional Passengers:
The Bike bikes are designed for one passenger only (excluding Tandems).DO NOT carry any additional passengers on the front or rear of the bike.
Weight Capacity:
This Electric Bikes are designed with a maximum weight capacity of 265 pounds for all models. The rear rack maximum weight capacity of a Bike (if applicable) is 25 pounds. Exceeding the maximum weight capacity can result in damage of the bike which can lead to serious injury.
Tires & Wheels
Make sure tires are correctly inflated. Check by putting one hand on the saddle, one on the intersection of the handlebars and stem, then bouncing your weight on the bike while looking at tire deflection. Compare what you see with how it looks when you know the tires are correctly inflated; and adjust if necessary. Are tires in good shape? Spin each wheel slowly and look for cuts in the tread and sidewall. Replace damaged tires before riding the bike. Wheels true? Spin each wheel and check for brake clearance and side-to-side wobble. If a wheel wobbles side to side even slightly, or rubs against or hits the brake pads, take the bike to a qualified bike shop to have the wheel trued.

General Warning

Like any sport, bicycling involves risk of injury and damage. By choosing to ride a bicycle, you assume the responsibility for that risk, so you need to know — and to practice— the rules of safe and responsible riding and of proper use and maintenance. Proper use and maintenance of your bicycle reduce risk of injury.
Your electric bicycle is designed for use by persons 16 years old or older. Riders must have the physical coordination, reaction time and mental capability to ride and manage traffic, road conditions, sudden situations and also respect the laws governing bicycle use where they ride, regardless of age. If you have an impairment or disability such as a visual impairment, hearing impairment, physical impairment, cognitive/language impairment, or a seizure disorder, consult your physician before riding any bicycle.
A special note for parents
As a parent or guardian, you are responsible for the activities and safety of your child, and that includes making sure that the bicycle is properly fitted to the child; that it is in good repair and safe operating condition; that you and your child have learned and understand the safe operation of the bicycle; and that you and your child have learned, understand and obey not only the applicable local motor vehicle, bicycle and traffic laws, but also the common-sense rules of safe and responsible bicycling. As a parent, you should read this manual, as well as review its warnings and the bicycle’s functions and operating procedures with your child, before letting your child ride the bicycle.


Make sure that your child always wears an approved bicycle helmet when riding; but also make sure that your child understands that a bicycle helmet is for bicycling only, and must be removed when not riding. A helmet must not be worn while playing, in play areas, on playground equipment, while climbing trees, or
at any time while not riding a bicycle. Failure to follow this warning could result in serious injury or death.
Your electric bicycle is for use by persons 16 years old and older, only. Do not let a child younger than 16 years old ride the bicycle.
