I spent a year guiding groups on Trek Powerflys. They were great. I’m not a fan of hardtails so had to be convinced by the folk who were paying for them that they would be ok.
They were ace. Even the bottom of the range ones that we had rode really nicely. The frame was surprisingly forgiving and I rode those bikes on all sorts of terrain. Flowy singletrack, up and down, was a hoot as was the field-boundary/woodland tracks/gravel bits that we took groups on.
They’d get out of sorts on more tech stuff, understandably, but not in any way due to the extra weight. We had to beef up the rear tyres and ended up fitting DH tubes full of slime to prevent rear punctures but, because of the Bosch CX motors, they only made the ride more fun.
I’m currently looking at getting something similar as a winter bike that I can cover in mudguards to commute on to. In an ideal world I’d also have a lovely lightweight full-sus ebike but those are beyond my reach at the moment.
