I’ve been commuting 10 miles each way on a 2011 Genesis Vapour since mid August. I used a mix of green lane, bridleway and field tracks, the bike’s been perfect for that. However, it got way too muddy and the bike was getting in right mess as was i so won’t bother going that way again until the spring time. It’s good fun but became abit of a chore after a while.
I also, at least once a week, take a more cross-country route on my mountain bike but that takes alot longer and is alot more muddy.
