Description
The Rail 5 625 is an electric mountain bike built for ripping the big stuff. It features the same high-end trail tech as Trek's analogue trail bikes, plus a powerful new Bosch drive system that's basically like having your own shuttle.
Trek's Rail is perfect for you if you're looking for an e-MTB that's just as ready to shred as non-electric trail bikes and you want a powerful Bosch drive system that'll propel you up climbs so you can keep your energy for the tech riding.
The Rail 5 features a burly alloy frame with 150 mm of rear travel and a 625 Wh Removable Integrated Battery, an e-MTB optimised 160 mm RockShox 35 Gold RL fork, the latest from Bosch with smart system Performance Line CX capable of speeds up to 25km/h including the new Bluetooth® LED remote for easy connectivity and all-in-one navigation and activity tracking through the eBike Flow app. Plus, a 1x12 drive train with a wide gear range so you can always find the ideal cadence for the motor, a dropper post, powerful 4-piston brakes for more downhill confidence and 29er wheels with nimble yet grippy 2.6" tyres.
Key features:
Bosch's new smart system gives you all the same power and responsiveness with a new Bluetooth-connected LED remote and eBike Flow app that puts even more control and customisation at your fingertips
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 to remove the battery without tools and lets you mount a water bottle cage
The controller has Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain
Made with the same hard-charging frame tech as Slash, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness and Active Braking Pivot (ABP)
The bigger battery means you can adventure for longer between charges
Please note: This model features tubeless ready wheels and tyres which offer a superior ride and less rolling resistance than traditional innertubes. This system requires tyre sealant to function correctly and this will be fitted in our workshop prior to despatch. The nature of this sealant means that the tyre may not be fully sealed until it has been ridden a short distance and therefore the bicycle may arrive with reduced pressure in the tyres. Please check the bicycle's tyres are inflated to the recommended pressure before cycling.
Please note: This model offers electric assistance up to speeds of 25kph (15.6mph).
IMPORTANT: This bicycle requires a suspension pump to set and tune its suspension correctly. This is not included as standard.

Sizing information is provided as a general guide only. This is based on the average rider riding the bicycle in the style for which it is intended. This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicycles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and responsibility on which size to purchase is yours.
