Specialized Turbo FSR Expert 6Fattie

Double-tap to zoom in


With the Turbo Levo FSR Expert 6Fattie, Specialized created a trail bike with amazing handling and performance, and then added the most efficient and powerful pedal-assist technology on the planet. The result is a bike that features all of their hallmark mountain bike design for a confident, nimble, and efficient ride, while offering a powerful Turbo technology with a pedal-assist motor so you can ditch the lift and leave the shuttle truck at the trail head. The motor is custom-tuned to deliver just the right amount of power you need. Its fully integrated, lightweight Li-Ion battery delivers power both smoother and quieter than anything in its class. The frame features an integrated battery mount at the down tube for fast and easy battery removal, plus a forged and braced motor mount at the bottom bracket. This lightweight M5 aluminum frame is paired with a 140mm-travel RockShox Pike RC fork, along with a Kashima Fox Float rear shock that offers plush performance over any type of terrain. An efficient 1 x 11-speed SRAM X01/X1 drivetrain gives you the range you need, while SRAM Guide RS hydraulic brakes provide unbeatable speed modulation as you bomb back down. Roval Traverse 650B wheels spin up to speed quickly, and 3-inch wide plus-sized tires roll over everything with incredible traction. A lightweight aluminum Specialized cockpit and Command dropper post round out the build on this all mountain machine that is the total package for anyone looking to go faster and have more fun.
