I think it was 2010 that I started cycling properly. I'd been walking to King's Buildings from various flats in Newington for the first few years as a student, but I was getting fed up of spending an hour a day walking, and then moved a wee bit further north as well, which added another 10 minutes each way. Getting the bus every day seemed like a waste of money, and the free university shuttle wasn't much quicker than walking by the time you factor in getting to the queue early enough to make sure you actually got on the bus. A couple of flatmates were also cyclists, so cycling seemed like an obvious choice.
So I went along to the Bike Station and got a Dawes road bike. It cost £130, which seemed like an enormous amount to spend on a bike (!), but I wanted to minimise commute time. Put a new saddle on it, and some plastic mudguards as soon as winter kicked in.
I do remember I fell off on my way home the first day of commuting, whilst trying to filter outside the Tesco on Causewayside. I think that remains the only time I've fallen off my bike without the "assistance" of a motor vehicle (I've cursed it now, haven't I?)
Unfortunately, the maintenance requirements of the Dawes outstripped my ability to fix it after a few years, and I upgraded to a new road bike (Revolution Audax) in Spring 2013. I made sure this one had mudguards, and could take a pannier rack. I can't believe I went three years carrying a rucksack on my commute every day. I didn't even think to take photos of the Dawes before I donated it back to the Bike Station.
The Audax lasted six months, before I rode into the side of a supermarket delivery van which had pulled out in front of me. Luckily I'd joined British Cycling just the day before! Their free legal help ensured I was able to get a replacement and some compensation without much fuss. Although the bike shop told me the frame was bent beyond repair, and the insurance was happy to pay for a new one, a friend was happy to take the old one from me and it's still going strong. The replacement Audax is also still going strong, and will have done about 10 000km by now.
I spent some of the compensation money on a fancy camera, and I'd learned about Strava not long before, so I splashed out for one with a GPS tracker. Having something keeping track of exactly how far I was cycling sparked the change from being an almost purely utility cyclist to someone who spent their weekends cycling as well. Did my first 100km trip last summer, to Innnerleithen and back, and the first 100 miler to Glasgow and back in April. Couple of 100km audaxes in there too, and hoping to do reach 200km some time this year.
I moved to the top of a hill a couple of years ago, and descending the occasionally icy roads were the excuse reason to add another bike to the collection - a very sensible upright bike with a kickstand, wide tyres, dynamo lights and a Dutch-style O-lock. I expected to do a few hundred kilometres on it a year, but it's already done 1000 km in six months. Cycling downhill on an upright is far more fun than I'd ever imagined it could be - instead of staring at a spot a few yards in front of my front wheel, I'm looking at Arthur's Seat as I head to work.
Discovering CCE a year or so ago (I think whilst looking for somewhere to vent about taxi drivers...) also lead to me taking a far greater interest in local cycling issues, finally joining Spokes, being a marshal at PoP, etc.
