The Trek FX+ 7S is a sleek, high-end electric commuter bike that seamlessly blends traditional cycling dynamics with advanced motorized support, designed for efficient and stylish urban transportation.
The Trek FX+ 7S redefines what it means to commute in the city by fusing classic bicycle design with innovative e-bike technology. Tailored for riders who prioritize an authentic pedal-powered feel enhanced by smooth motor assistance, this premium Class 3 electric bike reaches speeds of up to 28 mph thanks to its TQ-HPR50 mid-drive motor. The 36V, 360Wh internal battery supports a dependable 40-mile range in Eco mode, ideal for most daily journeys without frequent recharging. Weighing just over 40 pounds, the Alpha Platinum Aluminum frame and lightweight carbon fork work together to deliver responsive handling and a smooth, vibration-dampened ride through bustling streets and mixed terrain.
Riders can choose from two stylish finishes—Dark Star Matte or Lichen Green Gloss—while enjoying practical features like built-in LED lights, full-length fenders, and a MIK-compatible cargo rack. A Quad Lock phone mount transforms a rider's smartphone into a functional dashboard through the Trek Central app, offering performance data, customization options, and real-time ride monitoring. With a Shimano CUES 1x10 drivetrain and wide-range gearing, this electric commuter bike tackles both hills and flat stretches with confidence. Bontrager H2 tires ensure stability and grip without sacrificing quiet efficiency, while hydraulic disc brakes offer reliable stopping power in all conditions.
Refined Motor Performance with Smart Customization
Under the hood, the FX+ 7S sports a 250W mid-drive motor capable of peaking at 300W and delivering 50Nm of torque. Instead of a throttle, the motor encourages pedaling, offering a natural-feeling assist that appeals to riders who still want the sensation of a traditional bicycle. The near-silent TQ system responds dynamically based on pedaling intensity, seamlessly blending mechanical and electric power. Through the Trek Central app, users can fine-tune Eco, Mid, and High assist modes by adjusting wattage and responsiveness—tailoring the ride to their personal style or commuting demands.
Charging the non-removable battery is simple thanks to the 4A Mag Charger, which uses magnetic connectors to streamline the process. While actual range hovers around 40 miles in Eco mode, an optional 160Wh range extender boosts total capacity to roughly 520Wh—stretching potential distance up to 60 miles. This feature is invaluable for longer commutes or weekend trips. The carbon fork helps smooth out road noise and surface irregularities, and the sport-ergonomic geometry suits both performance-minded and casual riders alike. Integrated cable routing not only enhances the FX+ 7S’s sleek appearance but also minimizes maintenance and wear over time.
Smart, Reliable Components and Thoughtful Design
The Shimano U6000 10-speed gear system, paired with a Shimano CUES U6000 GS derailleur, ensures seamless gear changes whether climbing hills or cruising flat roads. The combination of a narrow-wide 46T chainring and an 11–48T cassette yields a wide 436% gear ratio range. Durable alloy crank arms and versatile flat pedals make the FX+ 7S suitable for a range of footwear, from cycling-specific shoes to casual sneakers.
Bontrager Paradigm rims—built with corrosion-resistant stainless-steel spokes—are tubeless-ready and paired with 700x40mm Bontrager H2 Hard Case Lite tires. These high-performance tires deliver the perfect blend of puncture protection, grip, and low rolling resistance, making them ideal for year-round commuting. Integrated front and rear LED lighting enhances safety without adding bulk. The rear light activates automatically with braking, boosting visibility in traffic-heavy environments. Additional cargo can be transported via the MIK-compatible rear rack, whether it's work essentials or weekend gear.
Instead of a dedicated bike screen, the Quad Lock mount turns your phone into a dynamic dashboard, offering GPS, ride stats, and battery level tracking via Trek’s app. Integration with Komoot and Strava enhances route planning and post-ride analysis, while over-the-air updates ensure your software evolves with future features.
Safety, Ergonomics, and Durability in Every Detail
Braking confidence comes from Shimano RS600 hydraulic calipers and rotors (180mm front, 160mm rear), delivering smooth, progressive deceleration even in rain or on steep descents. A Bontrager Comp alloy seat post with a 31.6mm diameter is compatible with dropper posts, giving adventurous riders the option to further upgrade for off-road or technical terrain. Available in sizes Small through X-Large, the FX+ 7S accommodates riders from 5’1” to 6’6”, offering a well-balanced posture that minimizes fatigue over long distances.
The stem and handlebar are seamlessly integrated, reducing visual clutter while improving steering precision and durability. Ergonomic Bontrager Satellite Elite grips minimize wrist fatigue, while the Bontrager Verse Comp saddle strikes a balance between support and comfort—ideal for upright city cycling. Additional mounting points on the downtube and seat tube allow for water bottles, storage bags, or even a second battery.
Certified under UL 2849 and UL 2271, and boasting an IPX6 water resistance rating (IPX7 for the battery), the FX+ 7S is built to withstand urban weather unpredictability. Even when soaked by rain or splash, the electronics remain protected. With a lifetime frame warranty and a two-year parts guarantee, Trek backs the FX+ 7S as a long-term investment for serious commuters and enthusiasts.
Final Thoughts
The Trek FX+ 7S stands as a modern interpretation of urban mobility—sleek, responsive, and technology-rich. For those seeking an electric bicycle that marries practicality with premium performance, this model hits all the right notes.
