You are not allowed to suggest banning cars as this park is a vital part of the city's road network!
Min suggested they should wear helmets. Maybe flourescents (as big white things on the road are tricky to see.)
Best suggestion wins a shot round the Meadows (not Holyrood park!) on the LB tandem or a try of the Raptobike lowracer or a copy of Velo Vision mag if you're tired of cycling / haven't time.
Photoshop suggestions welcome!
