How to charge the battery
Only use the charger that was supplied by TranzX PST. The use of any other charger voids your warranty,
may result in severe damage to the battery and electrical system of the bicycle, and in the worst case may
cause a fire hazard.

 Make sure the voltage specification of the changer meets your local voltage.
 Connect the battery with the charger.
 Fully charge the battery until the light turns green before riding the bicycle for the first time.

Charger LED Indication

 The red light indicates the battery is charging (Image 6).
 The green light indicates the battery is fully charged (Image 7).

Charging time
The Li-ion battery will take approximately 6 hours to fully charge.

Charger & battery protection

 The battery and charger have a built-in heat sensor. In case the heat rises too high, it will automatically
  shut down the system before any damage can occur.
      The charger will automatically cut off the power supply after 6 hours of charging.

Battery Maintenance
Have you recharged your battery pack lately? If 3 months have passed without recharging, it’s time to do it
again for several times. Charging your battery regularly will help insure maximum battery life and
performance and will help to avoid battery damage.

            Important Note

 Batteries must be charged prior to use.
 Do not incinerate or mutilate batteries. They may burst or release toxic material.
 Do not disassemble the battery. Return the bike to your authorized service dealer for service or repair.
 Store the battery in a cool and dry place. Always discharge the battery before bulk storage or shipment.
 Charge and discharge the battery at least every 3 months to maintain battery performance when being
  stored for an extended period of time. The battery could otherwise be irreparabley damaged.
  JD will not bear responsibility if those instructions will not be obeyed.
 In case of any irregular noise, variant temperature, or leakage from the battery, please stop using it
 Always store and cool the battery in a well-ventilated place out of direct sunlight.
 Do not charge the battery under a temperature below 0° and above 40° Celsius.

Fully charge the battery before first use!
Batteries should be fully charged immediately when they are received and immediately after each use.
 Li-Polymer batteries 4 to 6 hours
 With proper care and maintenance your E-Bike will provide easy support and be fun to ride.

Below are points that will help you to maximize the enjoyment you receive from your new E-Bike.

Factors to maximize the range of your e-bike

 Rider Input                    The more the rider pedals, the further the range.

 Difference in elevation        The flatter the terrain, the further the range.

 Weather                        Very cold weather could cause discharging the battery.

 Wind                           Riding with a tailwind will increase the range, riding into a
                                 headwind will decrease the range.

 Terrain                        The smoother the terrain, the further the range.

 Rider weight                   The lighter the rider the further the range.

 Maintenance                    A properly maintained bicycle will yield the greatest range possible.

 Tire Pressure                  Properly inflated tires have less rolling resistance enable a greater

   Batteries                    Properly charged and maintained batteries will yield the greatest
                                 range possible. Batteries stored below 10° Celsius will show
                                 reduced range. Never store batteries below 0° as this will result in
                                 permanent damage.
