Nobody tested this bike, nobody even saw it in real, so this statement seems to me a little bit optimistic !

A more realistic statement is to say that there are now bigger chance that you will receive a titanium folding bike maybe in July, maybe later.

How good will it be, nobody knows yet.

Why would Peter not communicate now that the can produce the Helix ? And also why not restart the pre-orders to collect some more cash ?

I see two reasons for that:

• the bike is a very first version, there is a lack of field test of it. Backers aren't real customers if something goes wrong, no warranty or anything, they can easily be used as first field testers to identify problems that will be fixed on the first commercial bikes.
• There are lots of history of kickstarter projects/products copied by Chinese companies before the KS project was finished. This could a reason to keep Helix as secret as possible even if this isn't good to launch a new product.
