I only have a 12" with Nylon rims. The 16" was a last try to make a dent in the market
but Swedes are not much into folders. Very few buy such. If one visit a Sport shop with
bikes they make long faces and say that one should go to a Sailors shop or to a shop
for MotorHomes or such.

The 16" with metal rims was some 200+ handmade ones to test the market for a modified
version. The picture is most likely from the gift to the Technical Museum in Stockholm.

I like my 12" very much. It has shorter wheelbase compared to Strida but are much more
normal to ride. A bad thing is the cord. It is a standard kevlar but half the width so one
need somebody to make too out of one sawing it in half. So if belt goes one are out of luck?

Frontwheel one could use a wheel to Rollator/Walker but the rear wheel have a drum brake
european style back pedaling.

I've talked to the guy that made the 200+ last 16" about repair and he says that
one have to be on one's own. He know nobody that have spare things.
Owners buy used ones and use as repair source.
