Trek Powerfly FS+ 6 Gen 4 - Nearly New – XL 2026 - Electric Mountain Bike
This Powerfly FS+ 6 Gen 4 electric bike is rated as an Excellent Grade, which reflects that the bike is in very good condition and can be considered to have been 'pre-pedalled'. Having been lightly used, there are some signs of use on the bike. The only minor visible marks are on the near drive side downtube, chainstay and top tube.
To ensure this bike meets our high standards for quality, it has undergone a thorough inspection by our professional mechanics. As with all our bikes, it comes with a 12-month Tredz warranty, plus any additional manufacturer warranty which may apply.
It's right for you if...
Are you itching to get far, far out there? The Powerfly FS+ is your dream ride. This fully-capable e-MTB takes you beyond the beaten track with the trail-smoothing benefits of a full suspension mountain bike for rough roads and light singletrack, and tons of power to make the ups just as much fun as the downs.
The tech you get
An Alpha Platinum Aluminium frame with a Bosch Performance Line CX motor (85 Nm, 250 W), a huge 800 Wh PowerTube RIB 2.0 removable integrated battery and Purion 200 controller. 130 mm front and 120 mm rear suspension from a FOX Float AWL fork with an air spring and RAIL 2.0 damper and a FOX Float Rhythm shock. Tubeless-ready wheels with puncture-resistant 2.4˝ tyres, a 12-speed Shimano SLX drivetrain for clean shifts, a Bontrager Line dropper post and hydraulic disc brakes.

* Mountain bikes are sized differently to road bikes. Typically, they are sized in inches as the first MTBs were produced in the USA. European brands like Lapierre and Haibike like to use centimetres for all their bikes. The measurements of their mountain bikes doesn’t match their road bikes but are like a simple conversion from the inches measurement. This is why we have included cm measurements in brackets for the Mountain bike column.
Read our bike size guide for more information on sizing.
