Been cycling for about 8 months now, and ride a carrera crossfire. Yesterday, I dropped into Halfords (from where I got the bike) to have my tyres topped up and picked up an adaptor so my old pump would work and headed for the main road, which had been newly done the evening before, I believe, with tarmac but was open to traffic as usual. Suddenly my bike felt like it had hit a massive bump, there was a loud bang and I flew over the handlebars and the bike landed on top of me.
The two men who came to help said it was the tarmac and it must have been hot still, while my boyfriend says they over inflated the tyres at the shop. Either way, I am somewhat nervous now and want to avoid this happening again, if possible as I tend to cycle along busy roads some of the time, including the one yesterday. I had never had this happen before, not even had a puncture in the less than 3 months I have had the bike, so am looking for advice on what most likely caused this and how to avoid falling off if it happens again on a road.
