Trek’s been building bikes that get riders stoked since their Wisconsin garage days in ’76. They’re the kind of brand that obsesses over every weld and gear shift, earning a cult following among roadies, trail hounds, and city commuters alike. For bike nerds like us, Trek’s name is shorthand for durability and smart design that just feels right.
When Trek jumped into e-bikes, they didn’t just slap motors on frames—they rethought the ride to keep that pure cycling vibe. The 2025 Trek FX+ 7S is their latest love letter to urban riders, a Class 3 e-bike that’s as nimble as a classic hybrid but juiced with a silent TQ motor for 28-mph sprints. It’s got the specs we drool over: carbon fork, integrated lights, and a slick app, all tuned for zipping through city streets with a grin.
The FX+ 7S is Trek showing off what they do best—blending pro-grade engineering with practical touches that make you want to ride every day. For commuters and fitness buffs who geek out on a bike that looks sharp and rides smoother, this is Trek’s newest must-ride.
My Experience Riding The Trek FX+7 E-Bike
Last year, I rode Trek’s Allant+ 8S, a Bosch-powered commuter that wowed me with its smooth ride in a growing e-bike scene. Now, in 2025, I’m on the FX+ 7S in Lichen Green Moss—a matte mint green with black accents that oozes understated style. With its compact cockpit, Quad Lock phone mount, 700x40mm Bontrager H2 tires, fenders, integrated lights, and near-silent TQ HPR50 mid-drive, this bike blends modern looks with commuter-ready practicality.
Climbing on, the hybrid geometry hits a sweet spot—sporty yet comfy, with my hands resting naturally on the ergo grips. The fixed stem worked for me, but it might not fit every rider’s preference. Pedaling off, the FX+ 7S barely feels like an e-bike. No throttle, just a seamless TQ motor so quiet I wondered if I’d secretly gotten fitter. It boosts your effort without taking over, like choosing a smooth espresso over a sugary energy drink—both get you going, but this one’s refined and keeps you in control.
The Trek Central app paired easily, letting me tweak Eco, Mid, and High assist levels for wattage and response, though the stock settings felt spot-on. The 250W motor (peaking at 300W) with 50Nm torque is great for city hills but won’t match a 1000W off-road beast—this is for pedal lovers. The 40mm Bontrager H2 tires roll quietly and efficiently, and you have room for up to a 42c should you want the extra volume for a little added comfort. The Shimano CUES LG400 1×10 drivetrain, with a 46t chainring and 11-48t cassette, shifts crisply across a 480% gear range, handling flats and climbs like a champ.
Smooth defines the FX+ 7S, from the natural assist to the quiet tires and sharp shifting. Lights, fenders, and a MIK rear rack make it ideal for daily rides, though the non-removable battery means on-bike charging, which might annoy some. If I were building my dream commuter e-bike, this’d be close to the mark. For bike nerds who love smart engineering and practical vibes, the FX+ 7S is a ride that’ll keep you hooked.
Range
Estimated Range (from Trek): 50 miles
Real World Range Test Results:40 miles
Trek claims the FX+ 7S can hit 50 miles in Eco mode, according to the Trek Central app’s range estimator, thanks to its 360Wh integrated battery. Curious to see how that holds up, I took it for a real-world spin through city streets, sticking mostly to Eco mode with occasional dips into Mid for hills. The result? A solid 40 miles before the battery called it quits, falling a bit short of Trek’s estimate but still plenty for a typical commute.
At 40 miles, the FX+ 7S covers the daily grind for most urban riders—think round-trip commutes or errands without sweating the charge. The shortfall likely comes from real-world variables like stop-and-go traffic, slight inclines, and my not-so-featherweight gear. For longer hauls, Trek offers a 160Wh range extender for about $550, which could push the range closer to 55-60 miles. While I didn’t test it, that option’s a smart nod to riders with bigger mileage needs.
For a bike this sleek and pedal-focused, 40 miles feels like a win, keeping you rolling without range anxiety on most city adventures.
Power (Motor & Battery)
The muscle behind the Trek FX+ 7S is the TQ-HRP50, a 250W mid-drive motor that peaks at 300W’s and pumps 50Nm of torque. This setup feels right on the FX+ 7S, and sticks to its pedal-first theme, supported by the lack of a throttle.
Commuters who like to pedal get that genuine pedal feel, with the added assistance when the legs want a break. The TQ-HRP50 mid-drive is basically silent and has a natural pedal assistance that feels very premium when riding.
Once you pair the FX+ 7S with the Trek Central app, you can tweak the pedal assistance at each level (Eco, Mid and High) in aspects like the wattage, assist percentage and pedal response. However, I found the factory settings to be sufficient and aside from playing with the feature for this review, I kept the stock settings as they fit the best balance for my rides.
Powering the TQ-HRP50 is the 36V, 360Wh battery (at 10 Amp-hours) that sits fully integrated into the down tube. Being fully integrated, that means the charging the battery must remain on the bike with no off the bike battery storage or charging.
Speaking of charging, the Trek FX+ 7S ships with a 4A fast charger taking charge times down just a few hours rather than the more typical 5+ hours of lower amp rated charges seen more often. Oh, and did I mention, the charger is a Mag charger? Yep, no need to line it up to plug it in, it just snaps to it from the magnetic connectors, fast and easy. Why don’t they all do this?
Components
When it comes to the component setup on the Trek FX+ 7S has a nice layout that keeps a focus on practicality true to its daily commuter theme.
Kicking off with the frame, its Treks Alpha Platinum aluminum paired to a carbon fork. This combo keeps the bike light and the carbon fork helps with vibration dampening as well as a 12x100mm thru-axle.
The Bontrager Paradigm rims are Tubeless Ready, 32-hole, 21mm wide, with Presta valves, and roll on 14g stainless steel black spokes. Tires are Bontrager H2 Hard Case Lite, wire bead, 30 tpi, 700x40mm, with a max tire size of 700x42mm.
The drivetrain sports a Shimano U6000 10-speed shifter and a Shimano CUES U6000 GS rear derailleur. It’s equipped with a ProWheel Alloy crank (46T narrow-wide chainring, 170mm arm length, ISIS spline) and a Shimano CUES LG400 LINKGLIDE cassette (11-48T, 10-speed), connected by a Shimano LG500 9/10/11-speed chain. The max chainring size is 46T for 1x setups.
The Bontrager Verse Comp saddle (steel rails, 165mm width) sits on a Bontrager Comp 6061 alloy seatpost (31.6mm, 8mm offset, 400mm length). The integrated Bontrager handlebar/stem comes in two sizes: 640mm width with 90mm virtual stem length for sizes S and M, or 680mm width with 90mm virtual stem length for sizes L and XL, both with 15mm handlebar rise and 0-degree stem rise.
Bontrager Satellite Elite alloy lock-on grips provide comfort, while Shimano hydraulic disc brakes (RS600 lever, RS405 2-Piston caliper) with Shimano SM-RT64 (180mm up front) and RT-EM600 (160mm in the back) centerlock rotors cover the braking power.
Screen / User Interface / App
The Trek FX+ 7S swaps a traditional display for a Quad Lock integrated phone mount, a one-piece stem design that uses your phone (with a Quad Lock case) as the front-and-center display. This setup lets you view ride data, calls, or music on a device you already carry, and it’s practical—when you park, your “display” goes with you. It’s also future-proof: no hunting for outdated display hardware if the bike’s discontinued, as software updates roll out via the Trek Central app.
So, what’s the catch? The mount’s proprietary, so you’re locked into this specific stem setup with no aftermarket alternatives outside of what’s available from Quad-Lock.
The Trek Central app powers the experience, offering ride tracking, service locator, and advanced features like motor tuning for Eco, Mid, and High assist levels, over-the-air (OTA) updates, and range estimations based on your current settings. The display also integrates with Strava and Komoot for fitness tracking and ride planning, using maps tailored to your remaining battery range.
This app-driven approach minimizes hardware and keeps the bike adaptable, evolving with e-bike tech as long as Trek supports it, which to me, is better than having a physical display that needs to stand the test of time long after this version of the bike fades away in Trek’s inventory.
Trek FX+7 Model Options
The Trek FX+ 7S comes in two frame colors: Dark Star Matte (black) and Lichen Green Gloss. It offers attachment points for accessories, including a rear rack and two bosses each on the down tube and seat tube for bottle cages or other gear.
Included accessories are fenders for weather protection, an MIK-compatible rear rack for cargo, a stem-integrated Quad Lock phone mount for using your phone as a display, and front and rear lights for visibility. Optional accessories include a 160Wh range extender for extra battery life, pedals, bottle cages, and MIK bags for additional storage.
The phone-based display (via the Trek Central app) shows battery level, range, speed, riding mode, ride time, clock, and heart rate (when paired with a heart rate monitor). Drive modes include Eco, Mid, and High, with a max speed of 28 mph (Class 3). The bike meets UL 2849 and UL 2271 safety certifications, with an IPX6 water resistance rating for the entire bike and IPX7 for the battery, ensuring durability in wet conditions.
