Riverwest24 bike race begins

MILWAUKEE (CBS 58) -- Motorcycles are all over Milwaukee this weekend, but a different kind of bike is taking over the Riverwest neighborhood. 

We're now three hours into the Riverwest24. 

The 24-hour bike race started as a community block watches in the neighborhood, giving people a way to welcome new people and strengthen the community together. 

Some people try to do the while 24 hours, but others form teams to break it up into shorter segments. 

Either way, it's always a popular event every year.
