I am heading to Panama for retirement! and am considering an e-bike. However, I am hitting a brick wall trying to find a reasonable method of shipping a bike there. Due to the Li battery, when I contact shippers like FedX, DHL, UPS, the responses range from "cannot do it" to charges of $3K, which can often exceed the original cost of the bike. As I understand it, the >100 Watt hour ratings do not allow the batteries to go on passenger flights. How is it that these bikes can come from overseas locations and not add these significant shipping costs into the cost of the bike? One of the reputable e-bike retailers I contacted would not disclose battery info sufficient to properly ship the bike (i.e., hazardous material UN number, I understand it is UN3480). As I understand it, even if you are shipping by air within the US, proper labeling requires the identification of this information and that the shipper be IATA certified, which allows the battery to be shipped by air. Maybe they only ship by land because of this? Can anyone help with this? If there are any readers of this thread that are e-bike suppliers, you have a great business potential in Panama - lots of retirees and great biking weather. Any experiences with shippers by sea?
