Control The Kids By Setting Some Rules - Having trouble controlling your bike because of a rambunctious child in the seat behind you? Consider setting some rules. Usually, if you tell him that he can't ride unless he rides safely, he'll get the point quickly and behave. Or try bribery: Promise a treat at ride's end if all safety rules are obeyed. Trailers are much more forgiving in such situations. Kids can even play a favorite card game or amuse themselves with other safe-to-travel-with playthings inside the confines of a bike trailer.
