Review: Trek Powerfly LT 7 Plus

Jan 2019

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.

Trek Powerfly 9 LT (2019) first ride review - MBR

Oct 2018 · Alan Muldoon

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.

Highs
  • Suspension, brakes and tyres are all on point. New battery layout is neat and easy to use.

Lows
  • Could have more generous reach measurements and shorter stems on all sizes.

Trek Powerfly 7 FS e-bike review - ridden and rated

Feb 2018

Built on the bones of the legendary Fuel series, the Trek Powerfly 7 FS is the top-of-the-line e-bike for Trek in Australia. It's got great pedigree, but we didn't love every aspect of its performance

Highs
  • Top notch build quality.

  • Frame feels indestructible.

  • Great rear suspension.

  • Torquey motor with plenty of range.

  • Will climb anything you point it at.

Lows
  • RockShox Recon fork isn't up to scratch.

  • Long rear end makes for sedate feel.

Trek Powerfly FS 9 LT review

Jun 2017 · Oli Woodman

An exceptionally capable package which will take you further and faster without the need for a lift pass. Buy if you’d like to scale climbs almost as quickly as descents and aren’t afraid to be a little different

Highs
  • Long wheelbase makes for almost absurd stability, superb mechanical grip from well-matched and supportive suspension, Drivetrain and motor play very well together, components list features plenty of excellent e-bike specific parts

Lows
  • Flimsy tyres are at odds with the rest of the bike, New ‘e-mtb’ power mode perhaps a little too keen for some

Trek Powerfly 8 FS Plus Review - Prices, Specs, Videos, Photos

Apr 2017

Price: $4999.00 | Model Year: 2017 A full suspension trail bike from one of the

Observations
  • A full suspension trail bike from one of the "big three" brands in the US, it offers 130 mm travel with custom tuning for the added weight and power of the bike, excellent weight distribution

  • Quick-release wheels, removable battery, and removable display make the bike flexible and easy to transport or charge, integrated Micro-USB charging port on the display panel to top your phone or GPS

  • Innovative adjustable length seat stays, knock-block steering with failsafe rubber guard and longer axles showcase how Trek is pushing bike technology forward, sturdy skid plate and minimalist guide

  • A bit heavier than expected at ~50.1 lbs, no bottle cage bosses, the Bosch CX drive system produces a bit more noise but offers excellent torque, battery is not as hidden or integrated as some competing models
