Bike as Checked Baggage
With Amtrak, you can send us back the bike without having to ride back yourself!
Our most popular touring ride takes you from Seattle to San Francisco where you use the Oakland Amtrak station to ship the bike back.
Bicycles can be checked in all cities that allow checked baggage.
Bike Shipping $10
Bike boxes $15
Bicycles must be partially disassembled in order to fit in an Amtrak bicycle box. Loosen and turn the handlebars sideways, and remove the pedals. Amtrak does not supply tools for disassembling.
Carry On & Trainside
If you are traveling on Amtrak you can bring the bike with you on certain trains. Standard full-size bicycles may be transported in bicycle racks located in the baggage car. Reservations are required as only Amtrak personnel are allowed in baggage cars.
