I have a lot of motor vehicles and related items shipped regularly. I just had a hood and front bumper shipped from Los Angelos to Seattle, the price quotes were from $210 to $855. Shipping prices for motor vehicles are often like airline seat prices. The cost is based on available space, not on the actual cost for the transporter.
Please post pickup and delivery city, type of bike, does the bike roll on its own, open or enclosed transport, pickup and delivery hours and days of the week pickup and delivery is available, and the timeframe you are in need of having the transport done. Is the bike a pristine rare classic, or a garage find that has been sitting in a barn for 50 years.
All the above needs to be answered for a recommendations and options to be posted.
