Apologies in advance, this isn't in relating to a boardman!
Got the lad a new bike but it has v brakes, have tried as hard as I can with water and running up and down the drive, but I can't get them to work. They hit the rim but the rim just keeps going. Anyone got any tips for bedding them in quick? Normally I would just ride the bike but obviously that's a bit tricky!

But of fine emery cloth? Are you sure the blocks are travelling enough, enough tension on the brake cable? Should be able to adjust on the barrel screws on the lever?

^ As above ...pull the cable through a tad more ..until you are happy enough that it has enough stopping power

I have tightened the brake up, also had a go filing the pads, no real improvement! I used to run v brakes bitd but then again I wasnt 4 and weighed a bit more!

I've got Shimano XT V brakes on my old Marin and can confirm that even they are shit. Almost as bad as Avid Elixir 1s.
I think that they will improve a bit though as they bed in. Bear in mind that when you first apply a rim brake in the wet it needs a couple of wheel revs to sweep the water off the rim. Plan ahead!
Edit to add. Have you tried giving the rims a good clean up with degreaser or detergent then maybe scotchbrite to get any grease/preservative etc off the rims?

Post some pics eddy, angle of the arms, angle of the pads, etc. Rim brakes tend to be fairly resistant to contamination, generally if you've got poor power then either the pads are slipping up the braking track when pulled or flex/resistance in the cable inner/outer.
