When we first transferred the GEOLUTION concept to 29er Trailbikes with the first prototype of the ION-G13, we broke new ground. Soon the concerns turned into pure enthusiasm. The ION-G13 can do more than you might think at first glance – uphill as well as downhill. Basically, the ION-G13 is a trail bike that lets you heat over your home trails and enjoy long trail tours… but there’s more. Thanks to its progressive GEOLUTION geometry, the ION-G13 takes you uphill even when other bikes are already at their limits. And downhill you take even the steepest passages with a subjective safety like you have never experienced before. The ION-G13 is a bike with an incredibly wide range of use – from the classic tour to the aggressive all-mountain. The ION-G13 is the bike we ride every day on our own trails.
