Yup.
I'm getting up there unfortunately and with several injuries that still haunt me I took advantage of a local demo day on a Powerfly.
I know the folks at the shop so I asked if I could take it on my club trails and they said okay.
I ride these trails daily to the tune of 1200+ miles per season so I know exactly how they ride and I have to say that the Powerfly was an absolute blast to ride!
It handled everything I threw at it especially the climbs.
Too soon for me to consider hanging up my bikes but when I finally fall apart it's good to know there's an option.
I'll never stop riding, ever.
