Like a much loved 1960s tv series, this moddish style of bike is in need of a reboot for 21st century. What would the ideal shopper look like?
There are plenty of folding 20" bikes of all grades but very few lighter-weight non-folding ones.
There is a heavy low-end version, a craftsman made premium one, a retro copy and a heavy duty cargo style version.
How about aluminium beam construction, gates drive compatible rear end, sliding rear dropouts.
Can you combine threadless steerer with versatile high-rise bars. Should it use a Brompton style front luggage boss or a front rack? V brakes or hub brakes? Dynamo hub or battery? Integrated bike stand?
To me the important characteristics are
low cost without being cheap and nasty,
low weight , because most of the riders are non-athletic women, young teenage girls or retired people,
grab and go convenience so integrated lights, rack, fenders,
ease of use so hub gears
Reliabiity, so premium 20" balloon tyres.
