I cycled about 5,000 miles last year without helmet, specific cycling shoes, without padded shorts, without GPS, video camera or electrolyte tablets.
I wish people would stop saying you need these things as it makes cycling appear complicated, expensive and dangerous to potential newcomers.
To be fair to the article in question, it isn't suggesting that padded shorts, GPS, video camera or electrolyte tablets are necessary.
Edit: I didn't read the whole article, did I? Doh!
I nearly always wear gloves for cycling. Fingerless in summer, full finger in winter. But I've never fallen off and had them save me so I'm not too fussed on the occasions that I forget/lose them.
I wear multi-purpose shoes that work OK on my clipless pedals and on flats. I wear specs anyway.
The only really silly one is "cycling socks", and the author is aware that it's silly. Personally I've got my cycling socks free with the glossy Tour de France magazine for the past few years.
One thing I would add is, in summer, some high factor sun cream.
And don't mention the hats.
