Thanks, that info will come in handy.

Also might be possible that a stand too long with an easily removable rubber foot could have some inches cut off.

I will post when I find a solution.  Time for another where there's a will there's a way... that list is getting long this lifetime. :-)

 I appreciate that, and i thought I found a much better technique than I first did that sounds similar, but got the same developing injury - can't avoid the same muscle or something.  Seems like no matter what you do you can't avoid the yank which is a completely different act than with an effortless side stand and problem is you have to do this a LOT.

Maybe a center mount sidestand is the answer, don't know what to look for or avoid in that style.  Maybe a motorcycle stand??

Really disappointed that RadPower has ignored my request for a solution or recommendation.  They apparently used to offer one that's now discontinued.

Thanks again.

I agree with the OP.  I bought a used RadRunner 1 and I'M BEGGING for a NORMAL side kickstand solution.  I am nearly 70 and love the bike but am developing a very painful center back pain that I keep re-agitating having to yank this heavy bike with no choice but to stand in an awkward position.   I could care less about center stand ease of 'working on it'.   This awkward yank problem is going to become real injury soon. 

Already had to return a stand I hoped would work.  So far it appears there's no kickstand for a 20" bike that is not for kids and/or not for this way extra thick and wide rail for attachment. I'm in biking wonderland and all the local bike stores are scratching their heads.

Thank you in advance if anyone can share a recommendation that works.
