Help us fit your bike.

We build UL 2271 certified replacement batteries for e-bikes whose makers stopped supporting them. Rad Power models are first. iGO and Juiced are next.

Before any model ships, we verify fit on real bikes. Not just the battery size. The cradle, the mounting rails, and the connector between the cradle and the controller.

That is where you come in. Tell us what you ride. Add photos of your battery, cradle, or plug if you can. Every submission sharpens the compatibility list for everyone.

In return: you get an email the moment your model clears verification, and first access when stock lands this fall.

We use this only for fit verification and stock updates. No marketing lists. Details in our privacy policy.
