I got an old Soul for peanuts, dredged ebay and FB classifieds for nice but cheap 26er parts, and stuck a set of wheelie bike 2.5 slicks on it. I think I’m into it for about £500, just because I got carried away on the wheels and got it a dropper post. I had a Soul bitd as my #1 bike, it’s kind of weird that I know have one as my going to the shops bike and it has the exact same wheels and fork in it. But it is ace.
(I got it a second set of wheels and some knobbly tyres, with the idea that I might do some retro mountain biking on it. But after one attempt I decided bollocks to that, time has not been kind, it doesn’t feel fun-bad like my fatbike, it feels like it’s supposed to be good but isn’t. But it’s still ace jumping it down the steps at tesco)
