Yes, Mt. Charleston is often rideable in winter when it hasn't snowed recently and the snow left from plowing has melted. There is always the potential for melting snow from the sides of the road to ice over sections of the road. Not nice going downhill on a bike. This is a national recreation area so the roads are not as wide as they are elsewhere in the valley. Both the Lee Canyon and the Kyle Canyon roads are heavily used by locals seeking winter activities (skiing, sledding, camping, and hiking). There are periods right around the snowstorms when chains or 4-wheel drive vehicles are required before you can even go up these two roads. However, snowstorms are hit and miss. I guess if you can ride in Canada in the winter, then you could probably ride in the mountains in our winters. I rather prefer riding in 50 degree days in January down in the valley.

Nobody can predict whether or not there will be snow even at the 5,000 foot level on Mt. Potosi off of Blue Diamond Road, State HY 146. I've seen the land completely bare in January and then so badly snowed in two weeks later that we had to hike in to a camp located there after parking the cars a mile or two away.
