Apparently there were a number of recalls on the Tikit
1) The Hyperfold cable was changed from two thin cables to one thick cable.
2) The "Aardvark" was improved to a loop handle to keep the seatpillar from cracking and breaking. The recall added a sheet metal brace that blocks the earlier cantilever-style handle.
RE the stem Bike Friday sell a fix, quote:
There is a modification that can be done to convert it to a fixed, non folding riser. This is essentially the same as the current model, The Pakit, which uses the same system. The stem is removed for folding with a quick-release rather than the folding riser. We sell this part for $110.
I thought this would be good advice for your cousin, cyclops, if they keep the bike.
