Decathlon

Ooh perfect excuse for me to visit my favourite sports shop :)

As you know, you should suggest to her to spend more money, or she'll just regret it. Buy cheap, buy twice. £300 is the lower minimum to get something half-decent, although it's probably more now. £400? I've seen Unipack-style bikes for £300, actually.

I know, I know. I did suggest spending more to her but it's not an option - she doesn't have £300, and she's self employed so there's no chance of a cyclescheme or similar. I was thinking maybe something second hand?
