Trek Rail 5 625W SX Eagle Electric Mountain Bike
With the capabilities of a non-electric mountain bike, plus an added boost to help you up the climbs after those fast, fun descents, the Trek Rail 5 625W SX Eagle Electric Mountain Bike will have you riding further, faster. The light yet durable Alpha Platinum Aluminium frame is paired to a RockShox 35 Gold RL fork and gives you 160mm and 150mm of bump-smoothing travel front and rear respectively so you can hit the roughest trails at speed.
Featuring much of the technology found on SRAM's top-end groupset, SX Eagle 12-speed offers smooth shifting performance and has a wide 11-50 tooth cassette and 36T chainring in a 1x setup. The dropper post, with frame size-specific travel, means you can quickly move the saddle out of the way as you hit drops, jumps and steep descents. Bontrager hubs and Alex rims make a strong wheel build and the bike rolls on Schwalbe's Nobby Nik Evo 29" tyres, great all-rounders that are easy to convert to tubeless and provides excellent protection against punctures.
Housed inside the down tube is the 625Wh battery which powers the Bosch Performance Line CX motor mounted in the bottom bracket. Smaller and lighter than previous models, sleek aesthetics are retained, and when the motor is not in use or you hit the 25km/hour limit, the bike won't feel overly heavy or sluggish. A Bosch Purion display allows complete control over riding modes from its handlebar position and you can view all your essential data.
Highlights
- The Rail 5 shreds just as hard as its non-electric brethren, plus it powers you right back up the mountain – no shuttle or lift necessary
- Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage
- Equipped with an external charging port for easy charging on or off the bike
- Made with the same exclusive frame tech as the Remedy and Slash models, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness and Active Braking Pivot (ABP)
- 1x12-speed SRAM SX Eagle drivetrain
