Using the bike

Riding the bike
Before taking off, make sure that you activate the battery by pressing on the button located on the side of the battery.

The 4 LEDs located on the top of the battery indicate the charge level. Turn on the display unit on the handlebar. Select your desired assistance level and begin pedaling. You’ll find the motor start working as soon as you start pedaling. When you use the brakes, the contactor located within these brakes will halt the motor’s assistance immediately. The left brake lever controls the front brake. The right brake lever controls the rear brake. You can also use the bike without electric assistance by turning off the battery (switch off the battery by adjusting the assistance level on 0). The motor will then feature zero resistance: you’ll be freewheeling. Select the appropriate gear by activating the 7-speed gear lever.

Quick-release devices
Tighten the adjusting nut by hand and move the quick release lever to the closed position. You should feel considerable resistance while closing the lever. If not, re-open and re-tighten the nut, then move the lever to the closed position so it is in line with the frame.

Adjusting the Saddle Height to Suit the Rider

Precautions are required prior to each use
Verify that the brakes and the front & rear lights are all working properly. Also, check the pressure of the tires. On derailleur geared bicycles the rear derailleur automatically tensions the chain.Make sure that all hinges and levers on your bike are properly locked. Indeed, when using the bike on a regular basis, the tension of the hinges’ adjustment and locking systems can change slightly. Whenever necessary, adjust the tension once again.This bike is not designed for rough usage condition, such as jumps, riding up or off of pavements, and riding on unpaved roads. For your own safety, do not modify the bike.Please note: if you use the bike frequently, it is recommended that you inspect the state of the fork, the frame, the suspension and the fasteners. The materials and components are subject to usage and wear and tear. If you have any doubts about the condition and safety of your e-bike, contact your dealer, who will proceed with the necessary inspection.

The battery

Installing and removing the battery
To remove the battery, unfasten the lock which is located on the battery box. Remove the battery by pulling it out.

To put the battery back into place, insert the battery along to the guide rail. Push it closely against the controller box. Click in place to fasten the battery lock.

Charging the battery
Never let a battery be charged unattended. battery’s voltage is indicated by the 4 LED lights located on the side of the battery, and also on the display unit located on the handlebar. Your battery must be charged in an ambient temperature, on a non-flammable and dry surface, away from any sources of heat, humidity or flammable materials and should never be covered. Here are the steps to be followed when charging your battery:

Step 1 Turn off the battery. The LED lights will be off.
Step 2 Plug the charger into the socket and then insert the charger’s

plug into the battery while battery is switched off.

When depleted, it takes 5.5 hours for the battery to completely recharge using the standard charger supplied with the bike.

Battery Autonomy and Lifespan
Autonomy
The bike’s autonomy ranges from 40 to 100 kilometers, depending on various factors (degree of assistance used, topology, rider’s weight, frequent stops /start-ups, hills, tire pressure, etc…) To increase the battery efficiency always begin riding while pedaling (using the throttle to start riding can decrease the riding range and eventually the battery life)

Battery
Your bicycles battery is just like any household battery. It contains a limited amount of cycle-life, which diminishes as it is being depleted throughout its life. When the available autonomy no longer meets with your needs, you will need to replace the battery.

Maintenance
If you don’t use your bike for a period of time exceeding 2 months, store it in a humidity-free area to protect the electronic components and make sure that the battery is not completely discharged.

Battery Safety Instructions
Your bike’s battery is an electric component made up of chemical elements. For your safety, it is imperative that you obey the following rules:

  • Always handle with great care
  • Always keep away from children
  • Do not disassemble, hit, pierce or submerge it Keep it away from temperatures exceeding 60°C Never create a connection between the contacts located at the bottom of the battery
  • Never let the battery charge unattended
  • Never sleep near a battery that is charging Only use the charger that came with your bike or supplied by your dealer
  • If your battery is damaged, do not use it

Safety and maintenance Recommendations

Safety recommendations
Helmet
For safe riding, always wear a bicycle helmet.

Tires
Inspect the wear of your tires on a regular basis and verify the tire pressure at least once a month. Tire pressure: 40-65 PSI depending on the weight of
the user.

Wheel-rims
Take care of any risk of damage in case of defective wheel-rims. Swap them immediately when the rim is worn out. Important: braking distance increases on humid or slippery ground

Gears
Like the chain, the freewheel must be kept clean and well lubricated. If the chain has become worn and needs to be replaced, it is likely that the freewheel will also have become worn and should be replaced as well. Take the chain off the freewheel and rotate it with your hand. If you hear a grinding noise or the freewheel stops suddenly after spinning, it may need to be adjusted or replaced.

Battery
WARNING: As with all mechanical components, the bicycle is subjected to wear and tear caused by usage over time. Different materials and components may react to wear or stress fatigue in different ways. If a component is worn, it may suddenly fail possibly causing injuries to the rider. Any form of crack, scratches or change of color in highly stressed areas indicate that the component should be replaced.
Maintenance
Bike maintenance and repair require specific skills and tools. Do not repair your bike or change any of its settings if you have the slightest doubt regarding your ability to correctly proceed with such work. Any adjustments or repairs that are not properly done can damage the bike and lead to accidents resulting in extensive injury. Use only genuine replacement parts for safety- critical components and contact your dealer when necessary.

Cleaning
Always remove the battery when cleaning. Use soapy water or water mixed with a gentle detergent, and then rinse it with clean water. Make sure that the controller located behind the battery compartment is not exposed to humidity as it contains electronic components. Do not use a high pressure washer!

Maintenance
Make sure your bike is safe for the environment. Used parts must be disposed of in appropriate selective sorting recycling bins. A battery which no longer works must be returned to your dealer so that he may pass it to a recycling company. Replacing the rear light batteries: remove the screw to access the batteries.
(It is recommended that you replace them every year) Engine: the motor does not require any sort of maintenance. Chain: It is recommended that you lubricate your bike’s 7 speed gearwheels and chain on a regular basis using appropriate products (ask your dealer for advice).
