'One of the best"
'Indeed the way it manages to balance big-hit compliance while still giving good pop is mighty impressive. Along with its stout chassis, long wheelbase and burly build kit, the Rail is capable of monster trucking its way down some pretty gnarly descents [...] the Bosch Performance CX Line motor is another key component to the Trek Rail’s all-round performance. In our experience, this is the best full-powered motor out there.'

'Trek has really gone all out with this bike'
'My first thought about the Rail 9.9 is how it resembles a new school American muscle car, with a ton of carbon fibre and lots of digitally integrated sensors, and as always, more power than its predecessor [...] If there was ever a bike that was ready for anything, the new generation of the Trek Rail 9.9 would be it.'

It was a close competition, but not much could match the Rail on every type of terrain. The Bosch system will get you up any trail and the geometry is as close to perfect as we have found for all-around riding.

Removable Integrated Battery
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security or just easier charging.

Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. You're ready to roll straight out of the box with the included TLR rim strips, valves and sealant.

Integrated speed sensor
You've got one less detail to sweat with the integrated speed sensor. The chainstay-mounted sensor stays protected while the custom hub-mounted magnet stays secure – no more error codes from mis-aligned sensors.
Mino Link adjustable geometry
Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.
Knock Block
Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked and your controls won't hit the top tube.
