I have many ideas, you never know...i don't think anyone will think those bikes are yours, ya would need to carry around some kind of folding ladder just so you could get on and off. chid could probably design one for you, consider making an inquiry. as compensation, you could regale him with the merits of high test WD40 and remind him not to use a clip on the rear axle nut.
How can I get in contact with you, I have an idea I'd like to talk to you about (yes, another one :O:O )
For the street riding type I do, I never had a problem with the clip on the rear axle nut
