Bike to Trike - Bike Axle Replacement
Along with other minor changes to my bicycle, I really (really) want to turn my bike into a tricycle. I figure having one front wheel and two back wheels would be the best (and by best, I mean simplest) arrangement. I'm also guessing that it would be fairly easy and perhaps weld-free. I want to get metal tubing/a metal rod that is the same size as my back axle, have it be about 4 feet long, and place two wheels on either side. The gears would be located in the same spot they were, just attached to the axle and not the wheel. I don't know how thick my axle is, but I can figure that out - the problem is, will the axle hold my weight? I plan on also loading some cargo (add, say, 50 pounds). I don't think the cost would be too much (over $50?) and should I need to weld something, my brother might still be able to do it. Do y'all think this would work? Would the axle hold 250 pounds of weight? If so, the axle could be threaded on the ends so as to keep the wheels in place, right? Thanks!
