RYCA stopped selling the RYCA kits and had a parts selloff a few years ago.

Their website now features something called Augmented Reality......not sure what that really is.  The information posted on their site seems to have been updated last in 2020 - except for their funding page which states the investment opportunity closed in May 2021.

If you want a Cafe' kit you will either have to find someone that bought a kit and never completed it, or buy a converted bike.....or make your own like several other members have done.
