Trek FX+ 2 Review: Takeaway

Ideal for most city and suburban rides, the Trek FX+ 2 has all the range you need unless you’re a regular long distance commuter. Offering enough power to flatten most hills you will see, it is a comfortable and agile bike to ride.

The low weight relative to many others in this segment is a big selling point, offering agility and fun as well as the power that comes from a motor with up to 40 Nm of torque.

Ideal for...

Light commuting
Errands around town or city
Shopping
Rides with the family
Longer leisure rides (with the optional range extender)

E-Bike Overview

One of the core design elements of the Trek FX+ 2 is being lightweight. At just 40 lbs, it’s the lightest town and city e-bike that Trek makes. It has the feel of a traditional bike with the added push that comes from the motor.

As a Class 1, pedal assist-only e-bike, it lacks a throttle and will only get up to 20 mph. With its rear-hub motor, it still offers a good kick up hills, offering up to 40 Newton meters of torque when you press hard on the pedals.

Various design decisions have been made in favor of lightness. It has a fixed fork that’ll be less comfortable off-road but is lighter than a suspension fork. The rear-hub motor will be lighter than a mid-drive motor, and the battery — at just 250 Watt-hours — saves weight, too.

Reasons to Buy

The Trek FX+ 2’s lightweight design is very nimble to ride. The range at 35 miles is ample for most daily riding, perhaps downtown or around your suburb as you go about your business. With the fenders, rack, and lights, you’ll be able to ride it in most conditions and carry a comfortable payload.

As a whole, you’d buy this e-bike if you were honest and don’t need a big range every day. You can add a range extender battery to get you up to 70 miles per ride, but this will add to the weight and take away from the handling of the e-bike. If you do the odd ride out touring the countryside, the optional range extender can be clipped on for those but left off for most daily riding.

Things to Consider

Trek says in its marketing materials that the bike can be carried upstairs more easily. This is still a full-sized e-bike and you would struggle to get it around hallways!

A minor complaint is the choice of the Bontrager Sport saddle. The saddle is unsuited to this type of riding and is likely fitted to save weight. Your behind may thank you for a slightly heavier aftermarket saddle that may add a pound or two to the weight but won’t tenderize your rump on a longer ride.

Without the optional range extender, the Trek FX+ 2 would score a half-point lower. Weight being the enemy of performance, we understand why Trek offers this e-bike with a lower range — most people don’t need a 70-mile range every day. If you buy the range extender, then you can clip it on for those days when you’re putting in serious miles.

Comfort

One of the big sacrifices made for weight is the choice of the motor. Though it’s supported by a torque sensor to make up for the riding quality, the 250W motor lacks the punch of similar mid-drive e-bikes that this competes with.

That said, the lightness of this bike means you should have more push up hills compared to a heavier model. That’s especially true if you don’t have much cargo and are on smooth terrain.

Durability
4.5/5
4.5

Trek offers a lifetime warranty on its frames and forks. The 9-speed cassette and chain will need replacing every 1,000 miles or so, and the bike will thank you for regular light maintenance like oiling the chain. Otherwise, the Trek FX+ 2 will serve you well for many thousands of miles of riding.

Style
4.5/5
4.5

Modest in appearance, this electric bike won’t turn heads in envy. It manages this appearance without being dowdy and boring. We like the proportions and shape of what is a modern and comfortable electric bike. If you want to stand out, choose the red color scheme, though the blue and black are more modest.
