Batteries come with a universal key that can be used to lock and unlock the battery to your ebike. Please note that universal keys are not unique to your ebike battery and may work with a variety of locks, including on other Rad ebikes. Universal keys do not offer the highest level of security compared to dedicated or unique key locks. We do not recommend leaving your battery affixed to your ebike in public unattended as it may pose a risk of battery theft.
For installation instructions, please reference the owner's manual for your ebike.

Safe Shield Explained

Ebike batteries are made up of multiple battery cells. Each cell in the Safe Shield Battery is separated by a special heat-absorbing resin. If something goes wrong with one cell, the protective resin is designed to prevent a chain reaction.

Long story short, Safe Shield batteries are designed to stop a thermal runaway event before it happens.

“Ebike pioneer ups the ante with safer batteries.”

FAQ

What does the Safe Shield Battery actually do?

It keeps you riding with confidence. Safe Shield batteries use thermal-resistant tech that stops thermal runaway at the source, preventing a single damaged cell from affecting the rest.

Why would I want this battery?

You’ll get added peace of mind and more range — all in a design certified to UL standards and built with the same high-grade cells used in electric cars.

Does this mean Rad’s old batteries were unsafe?

Not at all. Rad has always equipped our ebikes with top-tier batteries and name-brand cells tested to UL standards for ebike battery safety. Safe Shield simply goes further by adding an extra layer of protection.

Will it work with my older Rad ebike?

Yes. Safe Shield batteries are available in builds that match every Rad model, past or present. Just choose the version that matches your bike — semi-integrated or external — and you’ll be good to go.

Warning: Do not use the charger that came with any original non-Safe Shield batteries or any aftermarket/third party charger. You’ll need to charge your new battery with our updated charger.
