The Rail+ 9.7 Gen 5 suits advanced riders who want a full-power enduro e-MTB for big-mountain days at Hydraulink Trails or deep into Okanagan Mountain Park, shuttle-style laps without the shuttle, or aggressive trail and enduro duty. Its 160mm of travel, mullet wheel setup, and massive removable battery make it especially appealing to riders who want serious capability and all-day range without compromise.

Our team at Fresh Air will help you find the right fit in-store at both Kelowna locations. Stop by to work with one of our experienced staff members, or call 250-763-3425.

As a certified Trek dealer, our team can walk you through the Bosch System Controller and eBike Flow app setup, personalize your motor assist modes, and tune the RockShox ZEB Select fork and Super Deluxe Select+ shock to your weight and riding style — making sure everything is dialled before you leave the shop. We'll also set up your Bontrager Line dropper post, get your tubeless tire setup dialled in on the Brevard Pro XR tyres, and walk you through the Mino Link and leverage rate adjustments if you want to try different setups. We offer ongoing e-bike servicing and expert year-round advice. Drop into Fresh Air Pandosy (555 Groves Ave) or Fresh Air Dilworth (1656 Dilworth Drive), or book an appointment online.

Q1: What size Trek Rail+ 9.7 Gen 5 do I need?
Trek offers the Rail+ 9.7 Gen 5 in sizes S through L in this build, with a mullet wheel setup (29" front, 27.5" rear) on Medium through XL and full 27.5" wheels on Small. Check Trek's geometry chart for exact figures, or come into either Fresh Air location and our team will get you set up on the right size.

Q2: Is the Rail+ 9.7 Gen 5 right for Hydraulink or Okanagan Mountain Park?
Yes — with 160mm of travel front and rear, a RockShox ZEB fork, and aggressive Brevard Pro XR tires, the Rail+ 9.7 is well suited to the technical, high-speed terrain found at Hydraulink Trails and Okanagan Mountain Park.

Q3: How far can I ride on a single charge, and what factors affect range?
Range depends on your assist level, rider weight, terrain, and elevation gain — the 800Wh battery is among the largest in its class, and the Bosch eBike Flow app can help you plan and track rides, with the option to add a PowerMore range extender for extra-long days out.
