Teammates from the Wauconda High School football team gathered at a growing memorial near the site where Tyler Waldal was killed.
Waldal graduated from middle school this spring and would have been a freshman at Wauconda High School next month.
"He loved to ride his bike. He was chill. He cared about everyone, really nice," friend Jackson Ziagos said.
According to police, the crash happened around 10 p.m. Tuesday as Waldal was riding an e-bike and crossing Main Street in front of the high school.
Authorities said he crashed with a northbound SUV and was thrown from the bike.
Officials said the crash highlights concerns about the safety of motorized bikes.

"It's just a tragic situation. We really need to get a handle on keeping our kids safe," Wauconda Fire Department Chief Curt Hanselman said.
Wauconda Police Chief John Combs said questions remain about how e-bikes are regulated.
"A lot of these devices ... it says how many watts. But it doesn't talk about the speed, which is in the legislations," Combs said.
State Sen. Darby Hills, whose district includes Wauconda, worked on legislation this spring that strengthened laws regarding e-bikes, including age restrictions and licensing requirements.
"It's kind of of wild, Wild West for a while and we wanted to make sure there are some parameters statewide to make sure we're keeping kids and families safe," Hills said.
As the investigation continues, Waldal's family is grieving the loss of their son. Family members asked a friend to share memories of him.
"Tyler was a good student. He liked video games. He liked hanging out with as friends. He was a really good kid," said Cmdr. Heather Cognac, speaking as a friend of the family.
Police said no citations have been issued to the driver of the SUV involved in the collision.
Authorities said the driver remained at the scene and is cooperating with the investigation.
