As a skier, Tahoe in Winter is not a place to ride a bicycle, except maybe a fat tire ebike.

Portland, Seattle, Vancouver BC - good places to ride just not in January.


Every major city in USA has direct flights to Las Vegas. Florida is only a few air hours further than, say.... San Diego.
edit: Florida biking trails may be paved and lengthy, but IMO, a reputation as flat and boring.
Who knows Tucson? In Jan. As opposed to Phoenix, under 2 hours driving time.
