My style of on-bike entertainment has shifted over the years.
When I started cycling to work - 23 years ago on an old 10-speed, aged 27 (after 10 years on motorcycles - where I only tried headphones on one solitary occasion - I couldn't ride safely with music, but a mad mate of mine used to do 100 MPH with Nirvana at full blast) ...
.. I had a cassette walkman and it was either album-oriented rock music (doubtless on occasions I would have been actually singing along to Jethro Tull or Kate Bush
).. or alternatively Radio 3 on FM - which gave me plenty of insight into what following cars were doing via the ignition interference ... thinking back, surely I might well have been distracted by that sort of music - but the suburban roads were less busy back then.
Then in my mid-30s I discovered rave music, and there were occasions when I would charge home from work with pounding Goa trance on the cans - clearly fully reliant on my eyes. But the other side of "electronica" is the likes of Aphex twin - via Brian Eno - who took his cue in pioneering the ambient genre from Erik Satie - who fully expected the ambient sounds of the restaurant to form part of the performance...
My obsessive road-biking little brother who's mostly into the likes of Sibelius, once exclaimed in a condescending way that music would surely upset his (perfect) cadence - not being perfectly matched, beat for pedal stroke ....
Hundreds of hours of dancing to remarkably diverse "repetitive beats" (wearing earplugs) has left me able to syncopate - I can find any rhythm I feel like in any music - but then I'm just a fat, middle-aged bloke on a mountain bike and not an elite, clipped-in athlete on a carbon fibre bike with a 50 tooth front cog and a heart-rate monitor..
It's mostly laid-back "Deep House" mixes at the moment and I've been repeating the same mixes so much that it has almost become ambient music ...
