Summary of Reviews

We have read all expert and user reviews on the Trek Rail+ Gen 5. In summary, this is what cyclists think.

14 reasons to buy

The Rail+ Gen 5 is available in five builds, two aluminum and three carbon.
Experts effortlessly climb steep, technical terrain thanks to the effective geometry and excellent traction.
The Rail+’s playful handling allows reviewers to carve corners with ease.
Reviewers say the bike's traction and maneuverability instill confidence to tackle most descents.
Testers praise the natural, responsive, and strong power from the Bosch Performance Line CX motor.
Experts relish the traction provided by the Bontrager Brevard RSL SE tires (Rail+ 9.9, 9.8).
One tester gets 43.5 miles with 6,561 feet of elevation gain using mostly eMTB mode (PAS 3/4).
The bike's geometry and suspension progression can be adjusted via flip-chips. Optional headset cups are available for modifying head angle.
The Rail+ Gen 5 is compatible with a 180mm travel suspension fork and a coil shock.
Reviewers enjoy the comfort of the cockpit and other touchpoints.
The battery can be removed for charging on or off the bike.
The Bosch eBike Flow companion app allows tuning of motor power and viewing data.
The motor can be set to peak at 100Nm and 750W, though reviewers find this power too much for technical trails.
Trek offers a lifetime warranty for the original owner on the main frame and suspension swing arms.

8 reasons not to buy

The large 800Wh battery takes seven hours to charge.
Reviewers are disappointed by the large jump in size between the M and L frames.
One handlebar width (780mm) is used for all four sizes. An expert feels the larger sizes should have wider bars.
Testers would prefer to see proportionate chainstay lengths.
An expert says the plush suspension platform and high weight mean a lot of effort is required to lift and jump the bike.
The SRAM DB8 brakes (Rail+ 8, 9.7) lack stopping power, according to experts.
One test bike’s lower shock bushing develops play after just 62 miles of riding.
The battery release lever on one test bike is sticky.

Bottom line

The Rail+ Gen 5 is Trek's full-power enduro e-MTB with 160mm of suspension travel front and rear. All five builds have Bosch's Performance Line CX drive and 800Wh batteries. The latest Bosch system impresses, providing intuitive power without harsh cutoffs and plenty of range. Climbing and descending are a pleasure for reviewers, and the Gen 5's mullet wheelset provides welcome agility. Some experts complain about frame and component sizing. The Rail+ Gen 5's versatility and polished design earn it high marks, though some find it overpriced for the spec.

New 2025 Trek Rail+ Gen 5 on Test – Degraded?

Level 5 expert

It holds its own on flowing home trails and in technically demanding alpine terrain, but doesn’t necessarily shine in these disciplines. However, the platform offers many ways to address these shortcomings.

Trek Rail+ 9.8 GX Review: Bosch CX Mullet E-MTB

Level 5 expert

I was genuinely surprised by how much the switch to a mullet platform changed the essence of the bike… the Trek Rail+ 9.8 isn’t cheap, but it’s not outlandishly priced compared to other carbon offerings.

Level 3 expert

None of the clumsiness that characterized the previous Rail remains. In other words, despite the minor differences in geometry, you can safely call the new Rail+ a playful bike compared to its predecessor.
