It comes equipped with a Gen 5 Bosch CX Line motor that delivers serious torque for ripping up climbs and a huge 800Wh RIB 2.0 removable integrated battery. It’s topped off with all the bells and whistles you want – like carbon wheels and a wireless SRAM XX transmission.

The Rail+ 9.9 is the cream of the crop for epic e-bike adventures. It delivers an upgraded suspension package, a powerful motor for crushing big climbs and a massive battery that keeps you going mile after mile, plus, RockShox TyreWiz. This beast of a bike is built to deliver your every dream.

An OCLV Mountain Carbon frame with the Gen 5 version of the Bosch Performance CX motor system (85Nm, 250W) and a massive 800Wh RIB 2.0 removable integrated battery. A 160mm RockShox ZEB Ultimate fork with DebonAir spring and Charger 3 RC2 damper, and RockShox Super Deluxe rear shock. Tubeless Ready Bontrager Line Pro 30 carbon wheels, SRAM’s top XX AXS wireless electronic transmission that shifts clean even under load, plus SRAM Maven hydraulic disc brakes for stopping on a dime and a RockShox Reverb AXS dropper post.

You want a big, power-packed e-bike that’s built for massive adventure and doesn’t skimp on choice parts. You need plenty of travel for rough and rowdy terrain, a powerful motor that crushes climbs and massive battery to keep you going on your longest rides yet. Upgrades matter, and you want SRAM’s top wireless transmission and the added benefit of a RockShox suspension package.

The Rail+ delivers adventure with plenty of travel and power for getting after epic rides that take you peak to peak or chasing endless enduro laps
You get upgraded everything – suspension, drivetrain, wheels and beyond
You can tweak your geometry and suspension leverage rate for how you ride, and add in adjustable angle headset cups (sold separately) for even more adjustability
The powerful Bosch Performance CX system goes full gas up steep climbs and keeps you cool for the descents
The massive 800Wh RIB 2.0 battery supports you for big miles and can be easily removed for travel or storage

Bosch Performance Line CX motor

The Bosch Performance Line CX sets the standard for e-MTB performance with up to 85Nm of torque and an intelligent e-MTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.

New RIB 2.0

Removable Integrated Battery (RIB 2.0) makes it easy to remove your battery for more convenient charging or travelling, and you don’t have to worry about dropping it thanks to a secondary safety catch.

Mixed wheel size

You get a 29″ front wheel for monster truckin’ over stuff, with a smaller 27.5″ wheel out back for getting rowdy.

Adjust the suss for full send

Adjust the leverage rate with just a flip of a chip. Ride it in the Less progressive setting for a plusher feel perfect for rugged trails with square-edge bumps. Flip it to More progressive when you’re hitting big features and don’t want to bottom-out, or when you want to run a coil shock.

Transition to transmission

The SRAM Eagle T-Type transmission mounts directly to the frame, skipping that pesky derailleur hanger of yesteryear. This makes for a more robust system that’s not only cleaner-looking, it’s also more precise under load and easier to set up.

Bosch System Controller

The System Controller gives you a quick overview of your assist mode and battery level without distracting you from the ride. It’s integrated into the top tube so it’s out of the way but still easy to see with LED indicators. It also connects to the eBike Flow app via Bluetooth for accessing ride stats and performing system updates.
