General operating instructions

Before you ride

  1. Charge your battery until the green indicator light on the charger comes on, but do not charge it more than 10 hours.
  2. Check the tyre pressure.  Make sure they are inflated to 50 psi.
  3. Check the front and back brakes, and the condition of the front and back wheels, handle bars and saddle.  Make sure they are tight and fastened.  Make sure all quick-releases are locked and secure, and that all parts are in good working order.  Inspect your bike completely.
  4. If it was removed, install the charged battery in the battery seat of bike and lock it.
  5. Raise the kick stand if down.
  6. Sit on the bike and turn the bike on by turning the battery key fully to the right, then press the + button on the LED controller.  Red lights should illuminate to confirm the bike is turned on.

Battery charging

  1. Turn the key to OFF and remove the key.
  2. Insert the plug of the charger into the charging port of the battery box.  You can charge the battery either in the bike or you can take it out of the bike and charge where it is most convenient.
  3. Insert the charger into the wall outlet – DO NOT plug the charger into the outlet until you first plug the charger into the battery charging port.
  4. When the light turns from red to green, it indicates that the battery is full.  If possible, charge for an additional 2-3 hours to fully balance the battery.

After the green light comes on, the charger is in trickle-charge mode.  DO NOT leave the charger plugged into the outlet for long periods of time unattended.  Always charge the bike in a dry and clean place.  Keep the charger dry and clean.

Removing the battery
  1. Release the pin and lever, enabling you to tilt the saddle.
  2. Push and turn the key to the left, releasing the locking pin.
  3. Lift the handle on the top of the battery and slide out the battery from its position in the bike.
  4. Reverse this procedure to replace the battery.
Specific operating instructions
  1. Your bike has a key switch on the battery with an ON / OFF position.
  2. A battery meter is located on the top of the battery – if you press the button on the LED controller, red lights will show you the charge.
  3. To ride your bike, your key switch needs to be on, then press the + button on the LED controller, red lights will appear to confirm the bike is ready to ride.
  4. The front light switch is located on the LED controller.  The rear light switch is located on the back light.  On the first use, you will need to remove the plastic insulation strip.  The front light runs off the main battery, and the rear light uses 2 x AA batteries.
  5. The bike is fitted with Shimano derailleur gears; the button takes you up a gear, the leaver takes you down a gear.
  6. As you start to pedal, the motor will engage if the power is switched.  Press the + button on the LED controller to increase the power, and the press the – button to decrease the power.


Wheels should be properly placed in the forks or dropouts.  If you hear any irregular noises from the wheels or brakes, they should be checked and adjusted.  The wheels should rotate smoothly without wobbling from side to side.

Check the bearing play of the hubs regularly by lifting the bike and spinning the wheel.  It should continue to spin for several turns after you stop spinning the wheel.  The motorised wheel will not spin as freely as the non-motorised wheel.  To check the play of the hubs, try to move the rim from side to side between the forks.  No substantial play should exist.  If you detect play, or if the wheel is difficult to turn, please have a local bike shop look at your bike to have it serviced.


The rims should be smooth and without cracks, breaks or bulges.


Check your spokes tension regularly.  About the same tension should be on all the spokes.  If there is some minor loosening of the spokes, you may tighten the nipples, but it is recommended that you take it to a bicycle mechanic for proper adjustment.

If there is a loose spoke or if the rim has side play of more than 1/8″ (4mm), immediately have the wheel checked by a bicycle mechanic.  DO NOT ride with loose spokes.  Riding with loose spokes may cause the wheel to fail.


Inflate your tyres to the pressure of 50 psi.  Make sure the tyres are properly inflated every time you ride your bike.  Improper tyre pressure will make riding difficult, cause excessive tyre wear and cause premature failure of the tyres.

The tyres should be properly seated in the rim, and the fitting of the tyre beads and rim beads should be checked.  If the inner tube is pinched between the tyre and the rim, it may cause the tyre to fail.  Make sure the tyres are not cracked or unevenly worn.  Check for bulges.  Check the valve stem and make sure it is straight in the rim.  Irregular tyres should be replaced.


Before each ride, check to make sure your brake cables are free of obstacles and are adjusted and working properly.

Riding with brakes that are worn or damaged, or with worn cables or wheels that are in a poor condition, may result in losing control of your bike.  Wet weather may hinder the brake performance.  You may need more distance to safely stop in the rain or on a wet or icy road.

Battery / Fuses

Your battery is in a protective case with a handle to enable you to take on and off your bike with ease.  There is a locking key to lock the battery on your bike to discourage theft.

DO NOT attempt to open your battery box without first contacting your dealer, this will void your warranty.  If you suspect your battery is not working properly, you can test it with an inexpensive voltage meter.  If you get a zero voltage reading then check and replace the fuse.


Lubricate the chain with oil every 3 months to ensure it stays free of rust, as well as every time your bike is ridden in wet weather.
