I personally would of thought that the bike would be fine. Ditch the knobbly tyres and get some decent road tyres on. If you are only riding lightweight that should be fine.
Hi, yes I think your right. The bike is light anyway so I might get some new wheels and tyres for road use so I can just swap over for when I go out with the kids or maybe buy a cheap 2nd hand mtb to knock around with the kids.
