Customs agencies consider bicycles and bicycle-related gear headed to secondary residences or vacation homes to be "commercial" and do not consider these items exempt from duties and taxes. Any residence where you spend less than six (6) months of the year residing is considered a second residence. As a result, we recommend that you book your shipment with a purpose of “Buy/Sell/Gift."
Respecting your ownership of your bike, instead of using the full market value for your bicycle or gear, we recommend using either the "at cost" value or a nominal value for the bicycle to ship it without incurring market rate duties and taxes. We would then declare the bicycle as "Commercial - No Sale" because the bicycle would not be sold upon import.
