Battery holder Bottle Bob Bottle holder Reinforcement

Helps with the installation of bottle cage batteries on the bike frame and for those where drilling is not allowed, such as carbon frames. We call these “bottle bobs”. In fact, these fastenings are stronger and more secure than many of the frame eyelets, where the heavy batteries can tear the eyelets out of the frame tube. This gives you 2 more attachment points in addition to the 2 existing bottle cage eyelets. And of course you can also use them to attach more water bottles to your bike!

These CNC-milled aluminum parts can be firmly attached to any frame diameter with hose clamps and offer secure M5 threaded holes for screwing in the battery rail. The height of the aluminum is approx. 5 mm and is suitable for frame diameters up to approx. 57 mm.

The Bottle Bob is developed and manufactured in Canada by Grin Tech.
