The 25 miles is a bit much, but if your instrument/sporting gear can fit in a bag, you can carry it on a bike. There's backpacks for guitars, cellos and tubas and I regularly see kids cycling to their lessons with those. This is a fairly dense town though, so 5km max (20 minutes at child-speeds). Kids also can't drive cars, so if it's not happening by bike, it's not happening at all.
