Summary

The Trek Powerfly is a robust and capable trail e-MTB, praised for its confident climbing and stable descending. It features Bosch's Performance CX motor and RE:aktiv suspension for composed handling on varied terrain. However, it is noted for being heavy and less agile in tight turns.

Pros
  • Bosch Performance CX motor with e-MTB mode

  • RE:aktiv suspension for stability and comfort

  • Confident climbing ability

  • Integrated battery for low center of mass

  • Durable and robust build quality

Cons
  • Heavy weight

  • Limited agility in tight turns

  • Knock Block system can be inconvenient

  • Some tire grip issues

  • SRAM EX1 shifter limits gear shifts

Key Quotes
The Trek Powerfly LT 9 is its top-level longer travel e-MTB.

Super composed! Nothing rattles the Powerfly.

This thing climbs steep singletrack a lot easier than the Levo or Jam2, no doubt about it.

The Trek Powerfly descends with confidence, but it’s still on the heavy side.

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.

Flow's First Bite: Trek Powerfly LT 9 Plus

Oct 2018

Trek’s new 2019 Powerfly gives no mixed messages about its intentions. It is chunky, long, robust and built like a tank. With 160/150mm of travel, 40mm wide rims with 2.8″ tyres, e-bike specific FOX 36 the spec is undoubtedly up for a thrashing, and the chassis also. The newly integrated battery does wonders in making a …

Highs
  • Built tough.

  • Bosch E-MTB setting feels natural.

  • Fearless climber.

Lows
  • Length detracts from agility.

  • Heavy to move around.

Trek Powerfly 7 LT Review - Prices, Specs, Videos, Photos

Jul 2018

Price: $5499.00 | Model Year: 2019 A stealthy, long travel, all-mountain electric bike with longer wheel base and adjustable seat stay hardware to optimize geometry for climbing and descending, proprietary

Observations
  • A stealthy, long travel, all-mountain electric bike with longer wheel base and adjustable seat stay hardware to optimize geometry for climbing and descending, proprietary "Active Braking Pivot" rear suspension reduces skipping, Knock Block headset and Hartzell Hug impact-absorbing downtube bumpers allow for straight downtube

  • Trek-invented Boost hub spacing improves spoke bracing angle and support for larger plus sized tires, quick release thru axles are sturdy and easy to work with, direct-link rear suspension stiffens the chain stays and bottom bracket without compromising performance thanks to the DeonAir rear shock

  • Beautiful battery integration, Bosch PowerTube 500 disappears into the frame, keeps weight low and center, provides space for a bottle cage mount and accessories above, sturdy locking core from ABUS with keyed-alike code, battery has a built-in handle for secure removal and transport

  • Bosch Purion display does not have an active Micro-USB port, the PowerTube 500 is heavier than the older PowerPack design, longer wheel base isn't as nimble and the motor integration is flat vs. angled up (unless you get the carbon model), the motor is heavier than the competition, produces more noise, introduces some drag when unpowered

Trek Powerfly LT 9 first ride review

Jun 2018 · Tom Marvin

The long back end is a constant across the size ranges, and so while the front end of the large isn’t super long, it’s still a relatively balanced-feeling bike.

Trek Powerfly 9 LT Plus Review

Mar 2018 · Christoph Bayer

No mountain is too steep for the Trek Powerfly 9 LT Plus! In our group test, it was one of the most capable climbers. But would the Trek also cut as fine a figure on descents and in everyday riding situations?
