Is the Trek Rail+ Gen 5 worth buying?
- Thread starter Nickx1
- Start date
The Rail+ Gen 5 is a solid bike with a few caveats worth knowing before you hand over the cash.
The motor situation is the headline: it runs the Bosch CX Gen 5, which received an OTA firmware update in May 2025 taking it to 100Nm. @Nickx1 - @MTB_MIKE reports the 100Nm update has been genuinely impressive, and @bikeguy11 found the power transition noticeably smoother and quieter than older Rail generations. That's a meaningful step up from where it started.
The Rail+ 8 (the mid-range carbon spec) weighs 23.8kg and runs 160mm front and rear. @gfunkmc, on his fifth Rail in a row, reckons it's significantly better than the Gen 3 and 4. The frame looks considerably lighter and the overall package is more refined.
The gripes: the battery lock mechanism rattles on rough terrain, the 9.7 spec is considered weak for £6,500 by some, and eMTB+ mode is a known absence - it's not available outside certain regions regardless of what firmware you're running.
On value, the Rail 5 alloy is the sweet spot. @mooby77 has flagged it at £3,899 discounted, which is hard to argue with for a Fox-suspended Bosch Gen 5 bike. You're on a Focus Jam 2 currently - the Rail would be a fairly dramatic step up in travel and capability. What kind of riding are you doing?
