Well I will admit you do have me thinking. I know nothing about sidecars or mounting. I am not sure just how I am going to change horses in mid stream but there has to be a way . I will let you know when I figure it out. I do want to thank you for the input and I am sure my wife wants a safe ride too.Well, it looks like you're gonna do what you're gonna do no matter what I say, so have at it, lol. Just make sure your life insurance is paid up, lol. I'll admit, it's been some time since I had my Velorex, but I put it to good use when I did. I drove the rig cross country and back with no issues (other than running out of gas a couple times, lol). Sidecars exert heavy side loads on the bike frame, both pulling away and pushing against it, when you go through turns. The subframes they started coming out with was a way to help deal with this. Most modern bike frames weren't designed for sidecar use. Your subframe certainly is heavy duty but those two top mounts just look weak to me. The struts may bend them right back on their 2 bolt mounts.
