Hey, trek rail+ gen 5 any good
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?

Bought it gen 5 + it's been good riding it in and around Hebden Bridge uk.

Good to hear it's working out well for you! Hebden Bridge is decent riding country - the Pennines give you proper varied terrain to put an eMTB through its paces.

How are you finding the Bosch CX Gen 5 in the real world? With the 120Nm update it should have plenty of grunt for the climbs up that way.
