would like to ride a bike/trike/quad that hold 500+ pounds. Can i make or reinforce a preexsiting bike to work for me?

I want to take and preexsisting bike/ trike/quad and make it hold me. most modern bike have a 200 to 250 limit I weight in around 500+ pounds. I know this is bad and want to change, I loved biking as a child and thought I could buy one. Well I can but it would involve a small loan the cheapest ones are 1300+ dollars I was hoping for some ideas on making or improving plus keeping the cost lower.

this was last year, i hope you found an answer, i myself am building a bike with a 500 lb capacity from plans off the web site atomiczombie.com the plans are called the loderunner. you buy the plans and build your own bike. there are at least 2 plans that have a 500 lb capacity. the price depends on how much you spend on your parts, and the cost of the welding tools. i know nothing about bikes or welding, so this is all new to me. but the bike is a recomb trike with 500 lb capacity

Check out this site they have bikes designed for 500 LB riders that are around $550-$700 unless you want a trike .
I hope you don't mean bicycling. It's going to be very difficult if you're that heavy. It's difficult for me and I weigh around 180. I tried again a couple years ago and realized I'm not a kid anymore. You could have a welder fabricate one, but that's not going to be cheap either. Now if you're talking motorcycles, I've never heard of such a limit. If you take it easy, there shouldn't be a problem. You would know right away when you sit on it if there will be a problem. The problems would be the shocks bottoming out, tire pressure, and possibly the rims not holding up. I'd avoid spokes and go for the solid metal ones. Also, don't put too much weight on the handlebars.

You mean a pedal-power bike/handcycle, rather than a motorcycle? You should be able to adapt one, but it will involve some non-trivial engineering. You'll need stronger wheels and axles, for example, along with reinforcing the frame. If you are familiar with welding, reinforce the frame essentially by building a second frame attached to it: weld steel box beams or tubing along all the existing frame members, and weld those new members to each other at all of the junctions. For sturdier wheels, consider using high-performance wheelchair wheels. Those are generally rated for larger loads.

If you pick a bike that's heavy to begin with, like a Goldwing, you should be able to modify it to hold you. I'd add heavy duty rear shocks and maybe make a bracket to add a single extra shock to the front for. Then pull off all the extra unneeded weight (saddlebags, windshield, extra-lights, etc.). A lot of bikes have adjustable suspensions, and a 500 lb capacity is fairly realistic. Lots of heavy couples ride bikes together. Many couples aproach the 500 lb mark, and as long as you don't try to carry extra weight, you should be ok.
