Content Creator Invokes Science Fair Technology To Charge His Derailleur

Electronic shifting is all the rage these days. Unfortunately, batteries can die or get lost.

Watch Brendan Carberry’s satirical solution to replace AXS batteries below.

In this video, Carberry 3D printed a holder for two lemons and created a classic science fair lemon battery to power his electronic shifting. Lo and behold it worked!

While Brendan’s invention is obviously tongue-in-cheek, the earnest presentation of a science fair project powering bike shifting is just too good. The serious presentation of whacky ideas is Carberry’s bread and butter, and he has gained quite a following for it.

Take a tour through his Instagram and see for yourself tons of similarly well-executed ridiculous projects like a chocolate chip cookie warmer.

On his YouTube channel, Brendan dives into more detail about his thought process for his videos. See his longer video about his iconic Lego pedals below.

It is great to have an online ecosystem where riders can make a name for themselves making 3D printing comedicbike parts.
