Trek Rail AL Gen 3 Frameset

The Rail AL Gen 3 frameset is a tough aluminium foundation for building an e-MTB that lets loose on challenging terrain. The Alpha Platinum aluminium frame features a RockShox Deluxe Select+ RT shock with 150mm of rear travel and is designed for a 160mm fork, creating a platform for aggressive trail riding.

• Alpha Platinum aluminium frame, 150mm

Highlights

• Removable integrated battery: RIB is a battery with an integrated casing and a handle for easy removal and reinstallation in the frame without tools. It is the simplest way to remove the battery for transport, security or more convenient charging.
• Active Braking Pivot: Active Braking Pivot technology has allowed our engineers to optimise how the suspension responds independently to acceleration and braking forces. This means more confident control when you need it most.
• Bosch eBike Flow app: The new eBike Flow app turns your ride into a tailored experience. Use it to customise the motor's assistance, track your ride statistics or integrate your data with platforms such as Strava and Apple Health.
