Rider questions

Is this legit?

Fair question to ask any battery site. Safe Bike Battery is the rider program from Zen Energy and A1 Batteries, led by Dr. Ravi Kempaiah. The UL 2271 certification is held by Zen Electric Bikes Inc. in Dartmouth, Nova Scotia. And we take no payment before your model is verified, so checking costs you nothing.

When can I get one?

First stock lands this fall. Covered models get first-access emails in signup order.

What will it cost?

Pricing is published when your model clears verification. Joining the list is free.

Why do you want photos of my bike?

Rad changed cradles and connectors across years. Photos confirm the exact hardware on your bike, so fit is verified before any money moves.

Who installs it?

It is a bolt-on cradle swap with the included adapter, about 15 minutes at a bench. Your local bike shop can do it, and we supply shops directly.

I run a bike shop.

We wholesale to shops with real margin. See the dealer program on the main site.
