atob is the sort of magazine that will appeal to many residents of this forum.
It's primarily about bikes as transport - but the journeys (as in the magazine's name) don't need to be just by bike. Folding bikes are therefore one of the key constituents - in fact at times it's almost a Brompton fanzine.
It has observed and chronicled the rise of electric bikes in recent years - still waiting for some sort of significant advance in battery technology.
The latest issue has 7 pages detailing most of the UK mainline trainsets and how and where you can put your bike - not justing folding ones.
