Thank you so much Smallwheeler for a fast reply to my post. Yes, definitely, If I find anything wrong with my bike, I will take it to Bfold. I still have to wait for another week before I can tell if anything wrong. It seems like Bfold used to be the only Mezzo dealer in NYC. Knock on wood, i hope my bike will be in a great shape for a long time. What is the situation of Mezzo in UK? I wrote an email to a bike shop which is on Mezzo website as a dealer and they told me that they struck with Brompton and no more Mezzo. I found someone mention about LBS. What is it? I would love to find a place that still carries Mezzo bike just in case i have questions base on the bike especially my bike is the Mezzo i4. I am so glad to see Mezzo thread is pretty active. I thought my question would take more than a month to be answered but not at all.

My curiosity :

What about the seat post clamp? If i have a problem with it, can it change it with any generic brands?
My bike is the internal 4 gears hub. I think I would be find with that but just wonder would it be possible to change it to Shimano Nexas 8?

Thank you again so much.
