Summary

The Trek Powerfly is a highly capable trail e-MTB, praised for its powerful Bosch motor, adjustable geometry via Mino Link, and robust suspension system. It excels in climbing and offers a fun, stable ride across varied terrain, though its weight and battery life can be limiting factors.

Pros
  • Powerful Bosch Performance CX motor for efficient climbing

  • Adjustable geometry with Mino Link for versatile riding

  • Robust suspension system for smooth trail performance

  • Stable and confident handling on descents

  • Good range with 500Wh battery for longer rides

Cons
  • Heavy weight affects maneuverability and playfulness

  • Battery life may require careful management on long rides

  • Some models lack space for a water bottle

  • Motor can be noisy at high RPM

The Trek’s geometry is inspired, the shock tune correct and the bike always feels planted.

This is an excellent electric mountain bike with one of the best drive systems currently available, my personal favorite, and it’s probably going to be easier to find in person and test ride than a lot of competitors.

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.

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

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
