Trying to find hubs for trike axle.
Hello, I have a delta trike that I am trying to play around with a little. I would like to have hubs with a 5 bolt pattern (4.5in) so I can put various standard car rims on it. It is a 15mm axle and holds what looks to be a pretty common hollow trike hub. Am I going to need to manufacture my own hubs or is there another type of vehicle, (ATV, go kart, rocket sled...) that has something to convert a 15mm axle to 5 bolts? If there is nothing that would work perfectly, what would be the two cheapest/easiest hubs to weld together?
