Does the weight of the pendulum on a clock affect performance? - bikes themes for dual sim

I want to buy a clock kit, but with a small bicycle and equipment for the pendulum to a bicycle (about clock for my husband crazy bike). I hope the team will be heavier than the piece that comes with the clock, I wonder if this will cause the clock is inaccurate, or the little engine trouble.
