One bike for all occasions – with the Trek Powerfly FS 7, the American brand promises to have created a true all-rounder. The smart concept should please everyone from trekking and leisure riders to moderate trail adventurers. We tested the 120/100 mm travel eMTB with the Bosch Performance Line CX motor to find out whether the new Trek Powerfly FS 7 is the all-rounder that many have been looking for.
All-round capabilities
Overall concept
Good-natured and intuitive handling
Confidence-inspiring
Comfortable riding position and low top tube
Responsiveness of the fork is mediocre
No model featuring the Nyon display

This isn’t the first time you’ve ridden this bike, right? Correct. We attended the launch of this bike last year, but we always prefer to test bikes on home soil in Australian conditions. We went deep on the tech details, so make sure you take a look at our First Impressions piece and video …
An incredible technical climber.
Built tough!
Smooth power delivery.
Excellent Bosch eMTB motor mode.
Slow speed manoeuvrability isn't great.
Quite heavy.

If I had to think of one common theme that continually came up during our time with the Powerfly, that would be it—too damn fun. Over the months we’ve had this bike, we’ve done it all and it does it all with ease.

Up hill or down, ebikes take an absolute beating, so the new Trek Powerfly 9 has a beefed up the parts package to handle the additional abuse.
Suspension, brakes and tyres are all on point. New battery layout is neat and easy to use.
Could have more generous reach measurements and shorter stems on all sizes.
