The Trek FX+ 1 is the entry point to Trek’s FX+ e-bike line: a flat-bar fitness bike with a hub motor, a battery hidden in the down tube and a thumb throttle, at just under $2,000. I haven’t ridden it. I have filmed lighter bikes like the Velotric T1 ST and heavier commuters like the Aventon Level 3, and the FX+ 1 sits between them. Everything here comes from Trek’s own product pages, checked on Oct 28, 2026 and linked at the bottom.
Four versions, one bike
Trek sells the FX+ 1 four ways, and all four were $1,999.99 on trekbikes.com as of Oct 28, 2026. Two choices separate them.
The first is the frame. The standard FX+ 1 has a regular top tube and comes in S through XL. The Midstep drops the top tube so it’s easier to swing a leg over, comes in S through L and is about a quarter pound lighter.
The second is speed, and it matters more. The FX+ 1 is a Class 2 bike: pedal assist and the throttle stop at 20 mph. The FX+ 1S raises pedal assist to 28 mph, and Trek labels it a “Class 2/3 hybrid.” Trek doesn’t list the throttle’s top speed for the 1S. The 1S also can’t be sold or shipped to California, which Trek attributes to the state’s SB 1271 law.
Since the prices are identical, choose the 1S only if you’ll actually ride faster than 20 mph and your local rules allow it. If you ride bike paths where Class 3 bikes aren’t welcome, the plain FX+ 1 fits better. Our e-bike laws hub and the Class 2 vs Class 3 guide explain the difference.
Motor, battery and charging
Every version uses the same 500W rear hub motor with 60 Nm of torque and a 520Wh battery inside the down tube. Trek rates the range at up to 50 miles. Plan on less if you use the throttle a lot, ride at 28 mph on the 1S, or climb steep hills.
Charging uses what Trek calls EasyMag, a magnetic charger that snaps onto the bike instead of a plug you have to line up. It’s a 2.7A charger.
How light is it?
Trek lists the size M at 48.73 lb for the standard frame and 48.51 lb for the Midstep. That’s light for a bike with a throttle and an integrated battery, and noticeably lighter than the full-size hub-drive commuters I’ve filmed. It’s still heavier than a slim fitness e-bike like the T1 ST. The total weight limit is 300 lb, including the bike, which leaves a little over 250 lb for rider and cargo.
Brakes, gears and tires
The FX+ 1 stops with hydraulic disc brakes on 180mm rotors and shifts through a Shimano 8 speed with an 11 to 45 cassette, which gives a wide range for hills. The tires are 650 x 50mm Bontrager GR0 gravel tires, and Trek pitches them for mixed surfaces, not just pavement. The fork is rigid alloy, and Trek doesn’t list a suspension seatpost, so the wide tires are the only cushioning.
Lights, security and the app
The lights are built in: a 180 lumen front light and a rear light with turn signals and a brake light.
The bike pairs with the Trek Central app, and Trek’s eLock lets you lock the motor from the app or the display. It can also unlock automatically when your phone is close by. That keeps someone from riding off under power, but it’s not a replacement for a real lock.
Trek’s listings disagree on the display. The short spec says “full color display,” but the detailed parts list says “LCD display.” I’d check it in person before buying.
What isn’t included
The FX+ 1 has rack and fender mounts but doesn’t ship with a rack or fenders, and it has no front suspension. If you want those included, look at the FX+ 2 below.
How it compares
Against the Trek FX+ 2: same motor, same 520Wh battery, same 50 mile rating. The FX+ 2 adds a suspension fork, a suspension seatpost and a rack, and it costs $300 more ($2,299.99 as of Oct 28, 2026). The extra parts also add about 7 lb. If your roads are smooth and you don’t carry much, the FX+ 1 saves money and weight.
Against the Aventon Level 3, which I filmed: the Level 3 had a 733Wh battery, a suspension fork, a suspension seatpost and a rack, and it weighed 67 lb. The FX+ 1 trades that capacity and comfort for being about 18 lb lighter. Aventon listed the Level 3 at $1,699, sold out, as of Oct 28, 2026.
Against the Velotric T1 ST, which I filmed: the T1 ST weighs 36 lb and has no throttle. The FX+ 1 is about 13 lb heavier but has a bigger battery, a throttle, wider tires and turn signals.
For a more relaxed, feet-down riding position, Electra’s Townie Go! 7D EQ is $300 less at $1,699.99, with a 250W hub motor, a 250Wh battery and no throttle listed.
FAQ
Have I ridden the FX+ 1?
No. This page is based on Trek’s product pages, checked Oct 28, 2026.
What’s the difference between the FX+ 1 and FX+ 1S?
Top assisted speed and legal class. The FX+ 1 stops assisting at 20 mph (Class 2). The FX+ 1S assists to 28 mph, and Trek calls it a Class 2/3 hybrid. They cost the same.
Can I buy the FX+ 1S in California?
Not from Trek. Trek’s page says the 1S can’t be sold or shipped to California. The plain FX+ 1 doesn’t carry that note.
Does it have a throttle?
Yes, all four versions have a thumb throttle.
Does it come with a rack?
No. It has rack and fender mounts, but both are sold separately.
Pros and cons (from the specs and sources)
Pros: under 49 lb with a throttle and integrated battery; hydraulic brakes with 180mm rotors; wide 50mm tires; turn signals and brake light; magnetic charging; a step-over or Midstep frame at the same price; a 28 mph option for the same money.
Cons: no suspension; no rack or fenders included; 520Wh is smaller than many hub-drive commuters; 300 lb total limit; the 1S can’t ship to California; Trek’s display listing is inconsistent.
Who it’s for
On paper, the FX+ 1 fits riders who want a lighter, brand-name e-bike with a throttle for paved commutes and fitness rides, and who can carry or add their own rack. Choose the 1S if you’ll use 28 mph assist on roads where Class 3 is allowed. If you want suspension and a rack included, the FX+ 2 is the better match.
