On space would be difficult, as a bike normally require a surface to run on. But in space, on another planet, big asteroid or something wouldn't be a problem as long as there is enough gravity and some surface traction.
Of course there are issues like tires and bearing lubes that needs to be sorted out.
Yes, a bike will work in space. If it is a mountain bike it will work perfectly on the moon, but the tires may burst because of the pressure change in space. Since there is no oxygen in space, you can ride a bike perfectly, but on the moon there is no gravity so the bike will go faster and you may even fly with it. If you are pedaling hard there will be more resistance, if you are going slower the bike will ride smoothly just like on Earth.
Riding a bike on the shoulder of a highway can be risky due to high-speed traffic and limited space. It is generally safer to ride on designated bike paths or roads with lower speed limits.
