Trek Rail 9.5 Gen 4 Full Suspension Electric Mountain Bike 2023

The Rail 9.5 is a carbon electric mountain bike with long-travel suspension. It features an upgraded frame with longer reach for serious stability on the trail, and a suspension set-up and parts worthy of the gnarliest enduro laps. The powerful Bosch smart system motor will get you back up the mountain faster than you ever thought possible, and the huge 750 Wh battery makes the laps feel endless.

It's right for you if...

You're looking for a long-travel e-MTB that gives you a serious power boost without holding you back from hitting the techy terrain and big drops you love. You want to spend your cash on a carbon frame and worry about upgrading components later.

The tech you get

An OCLV Mountain Carbon frame with a 750 Wh Removable Integrated Battery, a super-responsive 160 mm RockShox 35 Gold RL fork with DebonAir spring, Motion Control damper and lockouts, a 150 mm RockShox Deluxe+ Select shock, the latest from Bosch with smart system Performance Line CX capable of speeds up to 20 mph (25 km/h in Europe), including a Bluetooth® LED remote for easy connectivity and activity tracking through the eBike Flow app. A Shimano Deore 12-speed drivetrain with an extra-low 52-tooth climbing gear.

Why you'll love it

• The Carbon Rail Gen 4 has the same enduro-inspired geometry and huge battery as the previous generation, but now it has a pocket in the top tube that makes Gen 4 compatible with Bosch’s integrated System Controller and Mini Remote
• Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy to remove the battery without tools and lets you mount a water bottle cage
• Bosch's smart system gives you all the same power and responsiveness with a Bluetooth-connected LED remote and eBike Flow app that puts even more control and customisation at your fingertips
• The controller has Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
• The frame is extra-stout with a 34.9 mm seat tube to accommodate more robust dropper posts, and an oversized head tube that works with burly e-MTB optimised forks for less flex and more precise steering

The final word

The Rail 9.5 is the go-to if you want a carbon ride, and are happy to upgrade the part as you go. It keeps the price down with a Shimano Deore drivetrain, but upgrades things that matter most, like a frame with longer reach and extra stability. If you're looking for an e-MTB built to rip and upgrade over time, look no further.
