Trek RAIL+ 9.8 Extreme Test Ride And Product Review

We ride some extremely technical trails on the latest 2025/2026 Trek Rail+ 9.8 on some extreme descents to get to the bottom of how the bike works and discover what its like at the limit. We also take it on our local trails. We do real world riding, and discover how far you can take a 800Wh battery.

We have done a few hundred km on this bike so we feel we have a good insight now to how ti rides.

Our test version came with carbon wheels and retails around €7000 depending where you are in the world.

The trails we rode in this video are not for beginners, so if you want to ride them, go with a guide and ride safe! You are very far from help if something goes wrong... 2800 metres of descending...
