The Story

It’s the first hot day of spring and David slams the shed door shut with a new optimism.

“Parenthood mixed with a career left me wanting,” David opens, pedalling in the direction of the woods. “Having to focus on family and work meant I was left with no time to ride. Sure, you can be selfish when you’re young. But when others rely on you, you need to make sacrifices. I figured that the buzz of a rapid descent would just be a souvenir from my youth, shelved until later in life when the kids move out.” 

But after discovering the Trailfox AMP David could reassess: “You wouldn’t believe how much easier it is to steal back those free hours now. I can condense so much more into 60 minutes that it’s like I’ve been given more time. And the best thing is that I know I’m doing something good for everyone, rather than feeling selfish that I’m focusing on me and letting other priorities slide.” David adds, revealing a familiar glint of excitement that comes from energetically greeting his kids after an hour of fresh loamy turns.
