Any ideas on where to look for good bikes online besides craigslist and ebay ?
The Improbable Bulk
Do you mean new or used???
For used, the two listed are about it... plus perhaps bikeforums.net "For Sale" listings... and a couple of other isolated spots After all, think of how you would answer the following question if asked...
Where ahould I sell my bike online?
You may also be able to search classified ads for your local newspapers...
Or local bike shops that have a used bike or two they have accepted as trade-ins.
For new, there are a several sites available...
