When you say "Road Bike" do you mean...
"A vehicle other than a POV (such as a motorcycle, moped, hang glider, golf cart or snowmobile (and/or the associated trailer))"
OR
"Ultralight vehicles (defined in 14 CFR ยง103 as being single occupant; for recreation or sport purposes weighing less than 155 pounds if un-powered or less than 254 pounds if powered; having a fuel capacity NTE 5 gallons; airspeed NTE 55 knots; and power-off stall speed NTE 24 knots)."
OR
"Automobiles, trucks, vans and similar motor vehicles; airplanes; mobile homes; camper trailers; horse trailers; and farming vehicles (see Ch 5, Part E for POV shipment);"
If it fits either the 1st or 2nd definition, it's considered a HHG and can be shipped. If it fits the 3rd definition, you're pretty much screwed, since the government will only pay to ship one POV.
If you're concerned about damage, the government will reimburse you for any damaged goods during shipping. You can also get additional damage insurance from the carrier, as long as the insurance cost does not exceed the cost of transporting your maximum weight (7,000 lbs)
