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.

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.

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.

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 …
Built tough.
Bosch E-MTB setting feels natural.
Fearless climber.
Length detracts from agility.
Heavy to move around.

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

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.

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?
