  1. [1] Child bike trailer Risk
    Statistic
    AAP guidance: bike-towed trailers preferred over mounted seats; infants <12 months too young to be passengers; helmets required for both child and adult
    “"Preferably, children should ride in a bicycle-towed child trailer rather than a bicycle-mounted child seat. Infants younger than 12 months are too young to sit in a rear bike seat or to wear a bicycle helmet."”
    Calculation notes 
    AAP positions trailers as the safer of the two passenger configurations without publishing a quantitative differential. The Powell & Tanz 6x ratio is consistent with the qualitative AAP preference. Helmet requirement applies inside trailers as well as on mounted seats.

  2. [2] Child rear bike seat Risk
    Statistic
    AAP guidance: bike-towed trailers preferred over mounted seats; infants <12 months too young to be passengers; helmets required for both child and adult
    “"Preferably, children should ride in a bicycle-towed child trailer rather than a bicycle-mounted child seat. Infants younger than 12 months are too young to sit in a rear bike seat or to wear a bicycle helmet."”
    Calculation notes 
    AAP positions trailers as the safer of the two passenger configurations without publishing a quantitative differential. This is the cleanest authoritative guidance for the comparison-anchor framing against the trailer entry. Also anchors the under-12-months contraindication used in the personal-factor multipliers.
