Is it safe to bike up Winnetka Avenue?
We don't rate roads as safe or unsafe: crash counts can't say how risky a ride is, and roads people like to ride draw more riders, so they see more crashes. The records here are also incomplete: most reports along it are filed under Los Angeles, where only 3% of reported bike crashes have a map location, so the numbers here are too low. What the records show: 1 bike crash was reported on or beside Winnetka Avenue along the climb from 2021–2025.
