Where to charge
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 for trip hazards, damage to the bike, battery, or charger.
When to charge
A new battery should arrive with between 50% and 75% of a charge. You can ride the bike right away, without charging, once the bike is assembled and verified as safe by a local, certified, and reputable bike mechanic. After the first ride, a new bike or a bike with a new battery should complete the battery charging process outlined in the Battery Balancing section.
We recommend charging the battery fully after each ride so your battery can power you for the full range the next time you ride Rad! The battery has no "memory" so you can charge your battery after each and every use, even if you just take a spin around the block.
A battery with a partial charge can be left without immediately charging back to full. It should be charged as soon as possible when the battery bar on the display is flashing to indicate the battery is low.
How long to charge
Charging the battery from completely empty to completely full typically takes between 3–7 hours. Charging time depends on various factors including distance traveled, riding characteristics, terrain, payload, and battery age. Take a look at the table below for more details.
