After some initial troubles with my Carrera Subway 2, I've been using it daily for the last 5 months and it's been fine. But it's now started to constantly judder, getting worse the faster you go. Looking down you can see the bike judder. There's no disc rubbing and the wheels look fine as far as I can tell.
Any ideas? I've searched judder on google and most of it is when breaking, and this is constant.
