Is the other side the same with the direction of the spokes going in opposite directions?
If so, swap either the front wheels or the rear wheels to make the spokes go in the same direction on each side.
Also, what could be a bit disturbing, is if you had directional tyres incorrectly mounted on directional wheels, such that if one was right, the other had to be wrong... Just shows you need to work with people who know what they are doing
