I don't know if it is the same here. I was doing well earlier in the spring, but we have had so much rain lately that I assumed peoples thoughts were not on bikes as much. That and it seams a lot more people are restoring and flipping than there used to be, maybe due to a tough job market. I do agree that the multitude of online methods to sell your stuff has resulted in more used bikes on line. Kijiji (Canadian thing I think) has just over 6000 listings right now for Calgary alone. Some 1200 are parts and accessory listings. We still have Craigslist, eBay, and Facebook Market Place too. I guess the good this is more stuff is being recycled rather than being trashed.
One thing I have noticed in the last number of years is that here we have a sweet spot on the calendar to sell bikes. It is a combination of the snow melting, the streets cleaned, and sunny weather, but there is a period of 1-3 weeks where if you have stuff ready to go it mostly sells. Then you sit on most of it till next year.
