DG, I've been to Reno many times but the last time was over 6 years ago. Only been cycling two years...
But I've driven the area a lot and the roads are good, some real nice areas to ride should be easy to find. Flat, hilly to mountains. I know there is a big bike ride around Lake Tahoe.
I do recall seeing a lot of cyclists during the weekends in the suburbs. Good luck I always enjoyed the many times I visited/vacationed in the area.
