Thanks for this link. Take a long look at pictures number 18 and 19. That latch assembly is sophisticated, elegant and unique. The latch lever lifts the two locking lugs that keep the swingarm secured to the main frame. Look at both pictures long enough to understand how it all works. Brilliant.

There is also a brass swingarm travel stop to control how far the swingarm is allowed to move when folded.

The ablity to lock the front and rear hubs together when folded will keep it from being a wobbly mess after folding.

Many little details: the spring on the derailleur, the chain guide, the cable routing, the handlebar/ stem area hinge assemply and rotating latch. Again, brilliant.

Beautiful welds and the machined and cast parts have smooth radius edges to remove sharp edges.

The seat post design is interesting and a clever approach to improving the ability to make a compactly folded bike. Being a standard 28.6mm round seat post allows a huge number of other seat posts to be used, including suspension posts.

When Helix gets to the point where they are shipping them regularly, rather than a pre-order and unknown shipping date, I will buy.

Smallboats approves!
