I used the afore-mentioned tube. Cycled a handful of times, once due to a train strike, mostly because of plans for an after-school Bike Ride. It was a reasonable cycling distance, but along a horrid A-road that was best avoided in rush hour, and there was nowhere to park because the bike shed was used for storing exam desks. Got a lift occasionally, usually because I was transporting something awkward like a CDT project or oscilloscope[1], but also to important exams or (on a couple of occasions) because $parent happened to be going in the right direction. I think I may have walked the whole way home once because of some sort of transport chaos; type 2 fun in school shoes.
[1] Note for teenagers: They were unwieldy CRT things in those days, and unimaginably expensive.
