What does a solid white line with a bike illustration indicate?

A solid white line with a bike illustration indicates a bicycle lane, which is a designated area on the roadway meant specifically for cyclists. The presence of this lane is intended to promote safety and efficiency for both bike riders and motor vehicles.

By clearly marking where bicycles should ride, it helps prevent accidents and ensures that the flow of traffic remains organized. Drivers are usually encouraged to respect these lanes, avoiding parking in them and being cautious when nearby to safeguard cyclists. This lane is particularly beneficial in urban areas where bicycle traffic is common and is essential for promoting cycling as an alternative means of transportation.

The other options do not apply in this context since there are no motorcycle, rider, or pedestrian lanes indicated by a solid white line specifically marked with a bike illustration. Each of those types of lanes has different signage or markings that distinctly separate their designated uses.
