Either way, maybe you want to know how those cyclists do it, the ones who go on bike tours.
Personal experience is a powerful teacher.
After 13 tours in 15 years, including 2 trips cycling from coast to coast, I've learned a few things. For example, the most important thing to have on a bike tour is plenty of time. It usually takes more than two months to bicycle across America. When my boss got my request for a leave of absence so I could ride coast to coast, he approved the request and then jokingly said the note would be pinned to his dart board. There's no way around it, bike touring takes time, but it is worth it if you really want to meet the people and see the landscapes.
