I don't have a road bike and I mostly ride my mountain bike on easy trails so I can't answer definitively. I would guess that there are a couple of months a year that would be difficult for a high mileage road rider due to either snow or the sand and gravel that comes with it. Groups of road riders are very common the rest of the year. There is a group at my work that ride their mountain bikes on the south slopes just about year round. In addition, there are plans afoot to convert the rail path from Kelowna to Vernon into a multi-use path that would be fantastic for riding. This combined with the KVR would create an almost continuous path from Penticton to Vernon that would avoid the highways and busy streets.
