It was easy to spot two wheels as bike riders young and old brought their rides to Kuehn Park Friday to register their bikes with the police.
And now it's now easier than ever to register because it's free.
The police department recently took over registering bikes in the city and they want to use this summer to register as many bikes as possible. No matter what the size of your spokes, police want to see a small, registration sticker on the back of your bike.
"The particulars are going to be the make, model, serial number, frame size, which is going to give you the wheel size, and then any particulars: if there's any add ons," Sioux Falls Police Public Information Officer Sam Clemens said.
Each sticker has a serial number. After registering, it can help match each bikes own serial number with its owner.
Katie Morehouse likes to ride her bike around in the summer and she wants to make sure she can keep doing that.
"I'm pretty worried because it's a new bike and I haven't rode a bike in a while," Morehouse said.
Spending a few minutes registering your bike may save it from being one of the hundreds of unmarked bikes the department sees each year.
"We take hundreds and hundreds of bike reports, and unless there's a bike registration sticker on that bike, it's almost impossible to return it to the owner," Clemens said.
Although you didn't have to show up today to have your bike on the police's radar because forms are available at the police department and online.
"Nobody expects to have their bicycle stolen, but doing a couple of steps like this and getting it registered ahead of time reinsures that if it happens to disappear, if somebody takes it, they'll be able to get it back," Clemens said.
Police are hoping to hold more registering events and are trying to inspire the community with a simple message bike rider Holden Kirking was happy to spread.
"You don't have to worry about getting it [your bike] stolen," Kirking said.
