E-bike crashes and injuries in California are increasing, a new study out of UC San Diego finds.
And those injuries are not only more severe compared with conventional bikes, they’re disproportionately involving kids age 14 and younger.
We’ll hear how doctors, lawmakers and biking advocates are responding to the risks posed by e-bikes – and by what some call emotorcycles – and we’ll hear your takes about how we can make our roads safer for all.
