FAQ

Is it a bike light?

No. Bike Buddy is a decorative bike accessory with glow — it is not a certified safety light and does not replace your regular front and rear lights.

Which bikes does it fit?

The mount is designed for common city and folding bike handlebars. Final fit details are being confirmed in testing and will be published here.

Battery & glow

Each buddy has a built-in rechargeable light module. Final battery and runtime specifications are being finalized and will be published before they change how you use it.

Can I swap styles?

Yes — that is the point. The base stays on your bike; every Bike Buddy style clicks into the same base.
