Can you please map out, or at least spell out some of these roads? How would you ride to Lake Tahoe? I presume Rte. 50 is NOT one of those roads with almost no traffic. Also are you on the eastern edge of Pollock Pines, as Google maps shows about 46 miles from Pollock Pines to South Tahoe (the closest part of Lake Tahoe).
Your area sounds appealing if you can pick the time of year (e.g. summer/late spring/early fall), as the O.P. plans., but not necessarily so great for road cycling during the wintry months (extending well into the Spring at higher altitudes, but not at lower altitudes). My California cycling familiarity is with the San Francisco Peninsula/Santa Cruz Mountains/Mt. Hamilton/East Bay area., which allows for climbing all through the winter except for a small number of days (plus rainy days).
Definitely not Route 50. The ride to Tahoe goes like this. Sly Park Road to Mormon Emigrant Trail to Hwy 88 over Carson Pass to Hwy 89 to Tahoe. I believe it is exactly 72 miles from my house.
The beauty of the area during the winter is we can leave from the house and go down first. Camino, Georgetown, Jackson, Placerville, El Dorado Hills, etc are all places we ride to/around. Pollock is right on the snow line so from time-to-time I do get stuck. We rarely get rain from April-Oct ( maybe three times.)
As another posted, if you are interested in big city living while riding, PP is not for you....but we did just get a Starbucks
