Seats are adjustable for different heights.  Each person pedals independently. We ask that each guest weigh 280 pounds or less.  If you are physically capable of sitting and part of a family or group then other group members can help you pedal if they are willing.  Babies and small toddlers can ride in a car seat (that you provide us) attached to a Rail Rider seat.  Please arrive 40 minutes early if you choose to use a car seat and let our guides know so they can secure it on a rail rider for you. Infants can ride in their parent’s front pack at no cost. Young children, at the parents discretion, can ride without a car seat but may not be able to reach the pedals.
