It's right for you if...

You want to have fun. You're searching for a playful trail bike with high-quality parts and plus-sized tires so that when you're out on the trail, the only thing you have to worry about is your face hurting from smiling too much.

The tech you get

Roscoe 8 features a strong Alpha Gold Aluminum frame, confidence-inspiring 27.5+ tires mounted to Tubeless Ready Bontrager Line rims, and a 120mm RockShox Solo Air fork with a TurnKey hydraulic lockout. Plus, a dropper post, a SRAM NX Eagle 1x12 drivetrain, and Shimano MT200 hydraulic disc brakes.

The final word

High-quality components for high-quality trail days. It's all about fun, but it's also all about performance. With a 12-speed drivetrain, hydraulic disc brakes, wide handlebars, and 27.5+ wheels, this bike takes trail riding shenanigans seriously.

favorite_borderWhy you'll love it

  1. It's more fun to be a better rider: Roscoe is so stable and forgiving, it's like an instant ability upgrade
  2. Even when the trail gets rough, the wide 27.5x2.8˝ tires can deliver confidence, traction, and stability
  3. The dropper post lets you lower your saddle on the fly so its out of the way on descents
  4. The RockShox Solo Air fork can easily be adjusted for a specific rider weight, and it's lighter than a coil spring
  5. The NX Eagle drivetrain gives you a wider range of gears for easier climbing in a simple 1x set up

Sizing & fit

The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
