Cracking restoration...

Wow, that's neat and elegant- is there a sleeve inside the main frame tube that the rear chain stay arm is welded to, resisting the massive vertical rotation turning moment on the rear wheel stay?

Not exactly sure what you mean..maybe these pics help

I'm struggling to understand how the back wheel is supported without any seat stays, relying on what appears to be just a single bolted joint at the chain stay/ main frame connection?
What am I missing?

The rubber suspension 'donut' just behind the pivot bolt.

An idea copied on Tesco's dual suspension BSOs

That rubber donut must have incredible forces trying to shear it vertically as the rear wheel arm tries to rotate on the pivot bolt.

love 'em rode my 1964 standard till the rear frame cracked and then donated it to the moulton preservation society ...the space frames of today are well beyond my price range and a little too posh for my day to day utility...went and bought a brompton to fill the gap but would have prefered the same again please but not to be found today

Lucky to get one with a front rack!

 

[Drzdave58]

Yes I was lucky..i found a guy with 2 of them for sale so I bought them both. But I sold this red one.

Its not scary to ride however I think I will avoid going down steep hills at high speeds. Great for short leisurely rides around town.

Yep the 'handling' only gets scary over about 10mph

You should have pinched the crankset off the red bike, it would have suited your build much more than the chrome steel original.

New crankset and 5 speed hub

Did you manage to get any new parts? Moulton Preservation has been shut since July due to illness and there is no indication if or when it might re-open, so the bits that wear out like bushes, bellows, etc are unobtanium unless you cannibalise another bike, which is what I had to do. There are alternative sources for rear pivot kits.

Didn’t really need any parts but now I have put my bafang kit on the bike to try out for awhile.
