Commission backs letter asking council to draft youth e-bike restriction under AB 22 34

Commissioner Paul Templin presented data at the March 9 MTSC meeting showing a recent increase in pediatric e-bike traumas and urged the commission to recommend a local ordinance aligned with AB 22 34 that would prohibit operation of class 1 and 2 e-bikes by children under 12.

Templin cited hospital-supplied figures showing a jump in pediatric trauma cases involving e-bikes: "There was this huge jump year over year from '22 to '23... it went from 14 trauma cases to 74," he said, citing Rady Children's hospital trauma data shared with the commission. He also referenced Scripps data indicating that for older teens (15
to18) e-bikes are implicated in a considerable share of severe injuries treated at regional trauma centers.

The presentation emphasized differences between e-bikes and conventional bicycles: motorized propulsion, greater weight and speed, throttle capability, and longer stopping distances that can raise risk in traffic. Templin argued that because e-bikes function more like motorized vehicles in some respects, a prevention-focused age limit for the youngest riders is appropriate.

Commissioners discussed enforceability and the role of school districts. Traffic Sergeant Christie Trampus said the sheriff's deputies have focused on higher-speed motorized units and motorcycles and have towed many illegal units; deputies have also been doing school outreach, citing and educating parents and children when appropriate. Several commissioners said the Encinitas Union Elementary School District already tracks students who bring bikes to school and could enforce a school-based prohibition on e-bikes brought to campus.

After discussion about education, enforcement practicality and family needs, the commission approved a motion directing Commissioner Templin and an identified colleague to draft a letter recommending that City Council draft a local ordinance under AB 22 34 narrowly limiting class 1 and 2 e-bike operation by children under 12, accompanied by education and a warning period prior to enforcement.
