The battery and charger that come with bikes by Rad Power Bikes are high quality and intelligent. When used as directed, these components can provide for years of reliable power and recharging. Follow these best practices for maintaining your Rad Power Bikes battery, and those detailed in your Owner's Manual, to keep your charger and battery powering all of your Rad Rides!

Charge the battery by using the included 48V 2 Amp charger (or a charger purchased directly from Rad Power Bikes designed specifically for your bike's serial number). The charger is rated for both 110V and 220V AC power outlets, so you don't have to worry about adapters.

The batteries can be charged on or off the bike; you can leave the battery locked to the frame when charging or you can remove the battery from the frame using the included keys and charge the battery on its own!

Always charge in a safe area that is dry, indoors, between 50 °F – 77 °F (10 °C – 25 °C), and away from direct sunlight, dirt, or debris. Arrange the bike, battery, and charger to eliminate the potential to trip on the charging cord, or for damage to occur to the bike, battery, or charging equipment while parked and charging.

To charge the battery:

1. Turn the battery off using the key and the key port (1, below). See the Help Center article on Removing the Battery for more information on the "OFF, locked" and "OFF, Unlocked" key positions.

2. Remove the rubber cover on the charging port on the side of the battery (2, above).

3. Plug the charger into the battery charging port (2, above).

4. Plug the charger into an appropriate power outlet. This should cause both charge indicator lights on the charger to illuminate with red lights.

5. Unplug the charger when charging is complete. When one charge indicator lights turns green, the charger will indicate the battery is fully charged. 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. Detach the charger as soon as possible once the green light indicates a complete charge to avoid unnecessary wear of charging components.

Charging the battery from empty to full typically takes 3-7 hours. In rare cases, it may take longer to allow the battery management system to balance the battery, particularly when the bike is new or after long periods of storage. For more information, see the Battery Charging Times Help Center article.

You can charge (or partially charge) your battery after each and every use, even after taking a short ride. The battery has no memory effect (unlike other battery chemistry) and is completely self-managing. For more information, see the When to Charge the Battery Help Center Article.

If you have any questions or issues with your battery, please discontinue charging, operation of the battery, and operation of the bike, and contact us directly.

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

Using aftermarket components, such as third-party chargers or batteries, that have not been tested by Rad Power Bikes for safety and compatibility may void your warranty, create an unsafe riding condition, damage the electrical system/bike by Rad Power Bikes, or result in serious injury and/or death.
