Amid growing concerns about e-bike safety, two bills introduced in the assembly this year aim to make it easier to ticket riders and reduce the top speed of some models. AB 1942 would require certain e-bikes to be registered with the Department of Motor Vehicles and display license plates, and AB 1557 would slow e-bikes that children are allowed to operate. Both bills are still being reviewed in committee. If either bill passes this year, it will take effect Jan. 1.
