Hi folks, my nephew has started Uni and for his 18tj birthday has asked if his aunties and uncles will fund a commuting bicycle. Being a old bike mechanic I was up for simply restoring his old Trek mountain bike. As it was a £500 bike in its day with some Deore LX components. However this has not met his expectations...

So with a budget of £250 can anyone help me find a bargain basement street bicycle to get him around the city. Anyone got discount codes / sale recommendations where I can make £250 budget stretch to something other than a shed?
Also I'm open to anyone selling a decent condition bike second hand if you have one going spare?
Cheers
James
