The Trek Powerfly LT 9.9 Plus is the result of several years of evolution. In this latest iteration, the bike features a classy carbon frame, a smartly integrated battery and the proven Bosch Performance CX motor. Will the bike still manage to convince our test riders?NEW: Before we get into the review, we would like […]
Excellent suspension
Balanced, composed handling

Front too low on steep descents
Cumbersome in tight sections

This isn’t the first time you’ve ridden this bike, right? Correct. We attended the launch of this bike last year, but we always prefer to test bikes on home soil in Australian conditions. We went deep on the tech details, so make sure you take a look at our First Impressions piece and video …
An incredible technical climber.
Built tough!
Smooth power delivery.
Excellent Bosch eMTB motor mode.
Slow speed manoeuvrability isn't great.
Quite heavy.

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.

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.

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

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.
