So far it does what it says on the tin, it was fairly easy for me to narrow it down to a choice of two, Tikit or Brompton. I tested several Bromptons and came to the conclusion that a Tikit couldn't be a worse ride, I was right, it is well ahead on rideability....not that the Brompton was unrideable.
On quality control I was 'lucky' in that my Tikit hadn't shipped when the recall notice was issued so mine arrived with the upgraded stem/latch part. My pros and cons were:-
the Tikit rides better
the Tikit is a very fast and easy fold/unfold indeed
the Tikit retains your contact points through the fold, no resetting seatposts or bars etc
the Tikit takes standard bike parts, I have a SS and a 9 speed hub gear rear wheel
the Tikit maintains the ring/cog relationship through the fold and has adjustable rear dropouts so no need for a chain tensioner or derailleur for Fixed, SS or hub gear use, plus it takes standard 135mm rear hubs and can take a disc brake, though I've stuck with the v-brakes for now.
the Tikit can be upgraded to take riders that exceed the Brompton weight limit

the Tikit is better suited to larger/taller riders, I don't feel cramped like I did with a Brompton
the Tikit can take front panniers on the standard rear rack and accepts my Ortlieb Backrollers on the front rack
If I'm commuting with a single pannier(the norm) then it can stay in place during the fold and after
Cons
the Brompton is a smaller and neater fold and plenty of local support
the Tikit ends up fabulously expensive for what it is...the import costs were eye watering you could buy a new Brompton for them alone
Tikit local support doesn't really exist...but we're only talking the frame and forks here all other bits are standard....I opted for the hyperfold which can be downgraded to the twiddly latch if you want but you can't upgrade if you go the other way. I also went for a fancy(read expensive) headset which is the only part I don't have the tools to maintain myself. Basically I took the decision that I can sort anything but a frame fault and if that happens then I can strip the bike and return just the frame for sorting. But I can manage without for however long that would take and their recall/failure rates seem good.
My overall decision was most influenced by my intended useage and I would never use the folder for long rides or touring. If I'd wanted that ability then I doubt I'd have opted for a 16" wheel folder.
