The Rail 5 625 is an electric mountain bike designed for rough terrains. It boasts the same high-end features as our non-electric trail bikes but is powered forward by the new, high-performance Bosch drive system. If you're looking for an electric mountain bike that offers the same off-road capabilities as non-electric trail bikes, and you want a powerful Bosch drive system to assist you efficiently on climbs, this bike is perfect for you. It features a robust aluminum frame with 150 mm of rear travel, a fully integrated, long-lasting 625 Wh battery, a RockShox 35 Gold RL fork optimized for electric mountain bikes with 160 mm of travel, a powerful Bosch Performance Line CX motor with 250 W output and 85 Nm of torque to provide pedal assistance up to 25 km/h, and a Purion controller. Additionally, it comes with a 1x12 drivetrain with a wide gear range for optimal cadence, a dropper post, strong 4-piston disc brakes for added confidence on descents, and 29" wheels with agile yet grippy tires. The Rail 5 625 offers the best price-performance ratio among our electric long-travel trail bikes. It matches its non-electric counterparts in terrains and, thanks to pedal assistance, helps you regain the mountain in no time. The larger battery also allows for more time on the trail. - The Rail does not shy away from its non-assisted siblings. It practically pushes you up climbs, making shuttles or lifts unnecessary. - The more powerful battery enables longer adventures. - The Purion controller features a Walk Assist function and an intelligent eMTB mode that automatically adjusts power according to the terrain. - It shares proven frame technologies with the Remedy, including adjustable geometry via Mino Link, a Straight Shot downtube for increased stiffness, and Active Braking Pivot (ABP). - Trek's Removable Integrated Battery System (RIB) looks great and is user-friendly: the battery is fully integrated into the frame for maximum protection, yet it can be easily removed without tools, allowing space for a water bottle. New Bosch Performance Line CX| The new Bosch Performance Line CX motor is lighter, smaller, and quieter than its predecessors, featuring better integration and agility. Moreover, it is even more efficient, allowing you to go further on a single charge. The intelligent eMTB mode automatically adjusts the level of assistance to varying terrain, consistently providing the necessary power for enjoyable rides. Special eMTB Lite Mode| Instead of a Tour mode, Trek's e-MTBs feature a special eMTB Lite mode that offers a more natural power delivery and a longer battery life. Removable Integrated Battery| The RIB (removable integrated battery) is a single-piece combination of battery and cover with an integrated handle, making it easy to remove and reinsert without tools. This feature provides convenience for transporting, securing, or charging the battery. Knock Block| Knock Block protects your frame when things don’t go smoothly. The steering stop prevents your handlebar from spinning completely in a fall, reducing tension on your cables and preventing contact with the top tube. What is the range?| Bosch's range assistant shows how far you can ride your e-mountain bike on a single charge. The preset data for an average rider and this bike model can be adjusted for more accurate range estimates.
