Failure to follow Battery Usage Information could result in unnecessary wear to the charging components, battery, and or charger, and could lead to an underperforming or non-functional battery and replacement will not be covered under warranty.

The charger works on 110/240 V 50/60 Hz standard home AC power outlets and automatically detects and accounts for incoming voltage.

 If you are not confident in your ability to successfully and safely perform all steps, we recommend having the work performed or checked by a local, certified, and reputable bike mechanic.

The battery should be removed any time the bike is stored or left unattended to prevent unauthorized use or accidental engagement of the motor. Remove the battery before attempting to service, adjust, or perform any maintenance on your eBike. Removing the battery will help ensure that the motor does not start inadvertently while service or maintenance is being performed. Keep the battery out of reach of children. Failure to remove the battery may result in severe injury or death.

Failure to properly charge, store, or use your battery will void the warranty and may pose a hazardous risk.

  • Check the charger, charger cables, and battery for damage before beginning each charge.

  • Be sure to charge in an area where it is clear and safe from any potential damage.

  • Place cables so they do not cause a tripping hazard to occur.

  • Always charge indoors in a cool and dry area and away from direct sunlight, dirt, or debris.

  • Always charge your battery in temperatures between 50 °F – 77 °F (10 °C – 25 °C).

  • The battery can be charged on or off the bike. To remove the battery, turn the key to the unlocked position, and take the battery out.

  • Charging the battery normally takes 3-7 hours.

  • Remove the charger from the battery within one hour of the green light indicating a complete charge.

  • The charger is designed to automatically stop charging when the battery is full, but unnecessary wear of the charging components could occur if the charger is left attached to the battery and a power source for longer than 12 hours.

  • Never charge a battery for more than 12 hours at a time.

  • Do not leave a charging battery unattended.

  • The charger should only be used indoors in a cool, dry, ventilated area, on a flat, stable, solid surface.

  • Avoid charger contact with liquids, dirt, debris, or metal objects.

  • Do not cover the charger while in use.

  • Fully charging the battery before each use can help extend the life of the battery and reduce the chance of over-discharging.

  • Never use a battery that is cracked or broken. Battery acid is highly corrosive and can cause severe burns! Battery acid can burn you if it contacts your eyes or skin. It can also damage personal property.

  • Do not yank or pull on the cables of the charger. When unplugging carefully remove both the AC and DC cables by pulling on the plastic plugs directly, and not on the cables.

  • The charger is expected to get relatively warmer as it charges. If the charger gets too hot to touch, you notice a strange smell, or any other indicator of overheating, discontinue using the charger and contact Fission Cycles Support.

  • Charge the battery only with the charger originally supplied with the bike from Fission Cycles, or a charger purchased directly from Fission Cycles that is designed for use with your specific bike serial number. Never us an aftermarket charger, which can result in damage, severe injury, or death.

  • Please take special care in charging your bike in accordance with the procedures and safety information detailed here. Failure to follow proper charging procedures can result in damage to your bike, the charger, personal property and/or cause severe injury or death.
