I'd love to have a trike but they arn't easy to come by. I did help a kid put a chain on one last summer so I got a look at how it worked. Lovely Lowrider has a trike kit for $200 but WHOOOO! I don't spend $20 on a build. So I've kicked the idea around on how to build one and have some blocks like what does the drive rod in the axle tube ride on? :? I'm gonna sketch my ideas on paint later and post 'em here. Just wondered if anyone else pondered this too.
