Anyone use one of these bike haulers and care to share your thoughts on them? It just holds the front wheel while the rear wheel remains on the road. I just want an emergency way of getting the bike home in case of a problem, and don't want the cost of a trailer or to have to store it somewhere and title/tags, etc. I wouldn't use it for long trips or anything like that; don't think I would trust it. Plus I don't think backing up would be very easy.
