Agree Kojaks are nice/very quick on the 20" wheeled TSRs. The beauty of the TSR at this wheel size of course is its sprung back and front

I owned a TSR2 for about 2 years and loved it. Have sold it though as I could not leave it anywhere in Cambridge locked up

Its too different looking and attracts attention quickly so very nickable.

If you are just using it for round trip rides or have secure places to keep it at either end of a journey then its fine. They are certainly very unique, unusual and comfy bikes to ride.

Ps I still own a 70s Moulton MK3. Its sprung back and front as well but with smaller 16" rims
