What type of hubs attach on only one side? I wish to build a tricycle and one of the limiting factors is getting the front hubs. I search for tricycle hubs on eBay and get nothing useful.
I need both the hub and axle or the axle dimension has to be a very common easily obtained bolt size.
What would I search for?
I think wheel chair hubs are what you are looking for. If you need disk brakes, Cannondale Lefty hubs are another off the shelf solution.
