June 4, 2025 - In mid-May, Trek launched its all-new lightweight FX+ 1, the company’s first-ever throttle e-bike and we were excited to secure a test model.
Powered by a 500-watt Hyena rear hub-drive motor with 60Nm of torque it’s supported by a 540Wh battery in the downtube, which can only be removed by a bike shop, and offers up to 80 km of range.
The entire system is compliant with UL 2849 and UL 2771 certification standards, the leading e-bike safety regulations.
The battery is charged by Trek’s new EasyMag Charger that uses a magnetic connector, so there’s no messing with plugs, making the process almost effortless. The novel EasyMag Charger is designed to be wall mounted at home, or brought on the go making for a compact system that fully charges the battery in 5.5 hours.
The controller on the handlebars features an easy-to-read display that provides just the right amount of information to efficiently manage your ride. With the press of a button you can view speed, kilometres travelled, and percentage of power remaining in the battery.
The three modes of assist are colour coded and can be activated by the push of the “plus” or “minus” buttons on the side of the display. The throttle control button is tucked in just underneath the display unit, making it almost unnoticeable.
The integrated Herrmans MR8, 180 lumen, 60 lux, LED front head light, and Sate-Lite M-15 rear light with turn signals and brake light functions are powered by the battery. The lights will continue to function for up to three hours even after the battery is drained.

Efficiency comes in many forms on the FX+1. The quality Shimano 8-speed Essa drivetrain comes with a large 11 x 45 rear cassette allowing for just the right gear ratios to dial in the perfect cadence on any terrain.
The Rush hydraulic disc brakes with 180 mm rotors provide ample stoppage power and the Bontrager GR0 Comp 27.5” x 50 mm tires on 36-spoke double walled rims also provide durability with good grip on- or off-road.
The FX+1 is built on a lightweight Alpha Gold aluminum frame and fork, and comes in either a mid-step or step-over design. The handlebars, stem, grips, saddle, pedals and seat post are all compliments of Bontrager, the company’s in-house brand.
A kickstand and bell come stock, and there’s space for two water bottle cages. There are mounts for both front and rear racks and fenders allowing you to accessorize the FX+1 to suit your choice of commute, journey or adventure. Trek also offers a full range of accessories to personalize the bike.
Out on the road the FX+1 performed well and the Hyena rear hub-drive motor gets you moving quickly up to speed. Like any e-bike it takes a bit of time to get used to the system as the motor works to maintain the maximum 32 kph. Overall it was relatively quiet and did a nice job.
The throttle acceleration was smooth and controlled, serving as both an enabler and a motivator. When your head says “go” but your body says “no”, the throttle is there to let you sit back and keep the wheels turning. It also motivated me to switch from the throttle to pedal power and embrace the ride.
The FX+1 was quite responsive, and the rigid frame provided confidence and stability while railing corners at speed.
I found that by adjusting the assist modes to my comfort level and the terrain, then adding the throttle during head winds or on hills and rough patches, I could net about 60 km+ on my rides.
In throttle mode alone I could get about 45 km on a full charge, and although it managed nicely to maintain the FX+1’s top speed, it took a toll on my thumb. With no range extender battery option, managing battery levels while on excursions is key.
Plus with the Trek Central app you can completely adjust your bike’s settings to enjoy longer range or more power, map out your perfect route, track your ride stats, and much more.
In the USA, the FX+1S is offered as a Class 2 (throttle up to 20mph/32kph) or as a Class 3 with pedal assist up to 28mph/45kph (not legal in California or Canada).
Servicing is also facilitated by an external junction box at the stem which allows quick and easy access to cables that are shape and color-coded.
Available in four sizes the sub-50 pound Trek FX+1 packs a lot of punch for an entry-level e-bike. It’s a great choice if you’re looking for an electric bicycle with a throttle option for commuting, fun or fitness. And best of all, is that it comes in at a very competitive price.
The SRP is $2,849.99 and for more information please visit here.
