my first (road) 'racing bike' was a 'Elswick Hopper - Whirlwind' (in Gold)
it looked nothing like this (it only had 5 gears )
My first 'racer' too I was 10 when I got it

I thought for years I'd misremembered it but found a pic of one in the right colours on t'internet a while back. I'll rummage through my album in the cloud and post the pic.
I had my first proper painful accident on that bike, showing off to a girl I liked and whacked straight into the back of her dad's car. Luckily it was parked and I was young enough for free dental treatment.
My mum had the OP bike too, I used to like riding it when I was big enough too.
Edit: Elswick Whirlwind, mine was from Cedar Cycles in Cambridge.
