If you’re ripping off 70 miles of off-road riding in a day, you’d probably go for a mountain bike or gravel bike. Maybe a cyclocross bike. Or you could, as Elena Lacey details in this joyous travelogue for WIRED, opt for a $5,000 titanium folding Brompton. Just don’t expect to clear any obstacles.

As I skidded down a hill, I cackled like a deranged vulture at the thrill of taking this tiny, light-as-air bike off-roading. It was perfect practice to get me pumped for the North London Dirt. I took a picture of what I think was a quail, or some kind of turkey. I sneezed as I passed fields of yellow flowers. I turned a corner and saw a castle. Scotland is wild.
