Problem (at least it seems it) with a bike my dad bought, which we share. It's one of these
http://www.sportsdirect.com/dunlop-rigid-velocity-26-inch-932036 but he bought it from someone for £30, still with packing on, and receipt!! so not tea-leafed. anyway the problem is that it doesn't seem to roll that easily?
I've put a bit of 3 in 1 oil on the chain/gears. but i can't work out if it's just the bike/tyres or if i'm missing something out.
It's not a decent bike, the seat is set as low as it can go, but it's far too high up for my liking, the gears are too short, gear lever on the right hand side goes the wrong way in my opinion. but still it's cheap and seems to work. and brakes are excellent!
