I was contacted by a friend who asked me to take a look at his sons bike for him. It was bought as a Christmas present and and had to go for some repairs. Being a kids bike it's taken a bit of a hammering, but he was a bit concerned that the cost of repairs being quoted was, at £172, almost what it cost for the bike when new (£250). I had a look and it appeared to me that they were overcharging him for some parts (£25 for a derailleur which they currently sell online for £15) and charging him for parts he didn't need (disc brake pads, for which the cable merely needed adjusted and possibly a chain and cassette). I've pointed him in the direction of a reputable bike repairer to have the work assessed and done there. What really concerned me was that when he had inquired about the bikes warranty he was told that because they didn't bring the bike back for its free post sale 6 week check, that the warranty was invalidated. Has anyone heard the likes of this?
