DIY bike sidecar

This isn't specifically a motorized bicycle mod, but I think it's a worthwhile [and not often talked about] idea.  

This Instructables.com entry gives instructions to making your own bicycle sidecar!


I'm not sure how safe it would be to have another person in this car, but for areas with low traffic, it may not be a bad idea!  Even better, you could mount a cooler on the trailer and start your own mobile ice cream business!  What better way to pay off that 66cc engine than by using a little engineering to turn it into profit!


You may be wondering if this would legally disqualify your bike as a motorized bicycle: Well, this can depend on the laws in your area, but usually bikes with 3 wheels still qualify, which is what's excellent about this mod!  I'd love to see someone do this with a motorized bicycle!
