I think five bicycles should be on sidewalks. Cars drive fast as road and might hit the cyclists who are riding the bicycle slowly. So riding the bicycles in the sidewalks are more safer. For example on sidewalks, cyclists can avoid pedestrians if they go slowly but cars cannot avoid cyclists. Cyclist might die if they crash into the car into the car. So riding bicycles on sidewalks is much safer.
CORRECTION:
"I believe bicycles should be allowed on sidewalks. Cars drive fast on the road and might hit cyclists who are riding slowly. Riding bicycles on sidewalks would be safer because cyclists can avoid pedestrians if they go slowly, whereas cars might not be able to avoid cyclists. A cyclist could be seriously injured or even killed in a collision with a car. Therefore, allowing bicycles on sidewalks could be a much safer option."

And here's an alternative way to convey the same idea:
"I think bicycles should be permitted on sidewalks for safety reasons. Since cars travel quickly on the road, there's a risk of cyclists, who ride more slowly, being struck by them. On sidewalks, cyclists can navigate around pedestrians more safely at a slower pace, while cars might struggle to avoid them. To prevent serious accidents and injuries, it might be better to allow bicycles on sidewalks."
