The Rail 5 625 is an E-Mountainbike designed for rough terrains. It features the same high-end attributes as our non-electric trail bikes, but it is propelled forward by the new powerful Bosch drive system. This model is for those seeking an E-Mountainbike that boasts the same off-road capabilities as traditional trail bikes while benefiting from Bosch’s robust power system to assist efficiently on climbs. It includes a sturdy aluminum frame with 150 mm rear suspension and a 625-Wh RIB battery, alongside a RockShox 35 Gold RL fork optimized for E-bikes with 160 mm of travel. The latest Bosch Performance Line CX motor equipped with Smart System provides drive support up to 25 km/h and features a Bluetooth® LED remote for seamless connectivity, navigation functions, and activity tracking via the eBike Flow app. Furthermore, it offers a 1x12 drivetrain with a wide gear range for optimal cadence, a dropper seat post, powerful 4-piston disc brakes for added confidence on descents, and agile 29" wheels. The Rail 5 625 stands out as our electric long-travel trail bike with the best price-performance balance. Off-road, it performs on par with its non-electric counterparts, and the pedal assistance gets you back up the hill in no time. The larger battery also allows for extended time on the trail. - Bosch’s new Smart System gives you full control and enhanced customization options, thanks to the new Bluetooth-connected LED remote and eBike Flow app. - Trek’s Removable Integrated Battery System (RIB) looks sleek and is user-friendly: the battery is fully integrated into the frame, providing excellent protection while still being easily removable without tools for transport, security, or easier charging. - The controller features a Walk Assist function and an intelligent eMTB mode that automatically adjusts the required power based on the terrain. - It utilizes proven frame technologies similar to the Slash, such as adjustable geometry via Mino Link, a Straight Shot downtube for added stiffness, and Active Braking Pivot (ABP). - The more powerful battery enables longer adventures. **Removable Integrated Battery:** The RIB combines the battery and cover with a built-in handle that can be effortlessly removed and reinstalled from the frame without tools, simplifying transport and charging. **Bosch Performance Line CX Motor:** This motor sets new standards with up to 85 Nm torque and an intelligent eMTB mode with Extended Boost that automatically adapts the support level to the terrain. **Bosch LED Remote:** The LED remote allows you to easily switch through support modes, activate push assistance, or turn on optional lights. Bright LEDs provide visibility of battery status and current support mode in all light conditions. **Bosch Smart System:** The Smart System connects your E-Mountainbike more than ever, as the LED remote links with the Bosch eBike Flow app to view ride data, make adjustments, and carry out system updates. A display can also be added for an organized view of your ride data. **Active Braking Pivot:** This feature allows engineers to fine-tune how the suspension independently reacts to acceleration and braking forces, providing increased confidence in critical situations. **Bosch eBike Flow App:** This app personalizes your ride, enabling you to adjust the motor support behavior to your needs, track ride statistics, and integrate data with apps like Strava and Apple Health, as well as offering useful features like navigation and service reminders.
