Trek Rail 9.5 Gen 4 Full Suspension Electric Mountain Bike 2025 in Black Olive

Season:2025Sale

Brand:Trek

Code:41679BLKOLI

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.

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 mini remote and system controller 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.

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 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.
