At Ibis we try to make bikes that are versatile, bikes that blur the lines between categories, bikes that create fun in a multitude of settings. That’s what it’s all about, right, having fun?

Bikes don’t get a lot more versatile (or fun) than the Tranny 29.

First, it’s a lightweight, nimble 29er hard tail.
It also converts to a single speed with surprising ease.
And in single speed guise, you can run a smooth and quiet running Gates Carbon Belt Drive.
Finally, it’s easy to break apart for travel if you need to fit it into a confined space (like a suitcase or an apartment in New York City).

The Tranny is a playful bike. The stock setup comes with a 100mm travel front fork, giving the bike a super lively feel (yes, we said lively 29er). A 120mm fork option is available, which mimics the Ripley’s highly regarded front end geometry, only with a lower bottom bracket height and the confident handling that inspires.
