I love my two Dahon Dash, but I don't think a PC Reach is essentially a Dash. A Reach has disk brakes, thru-axles, a smaller fold and front/rear suspension.

Helix is vapor-ware. Reach is real. And, btw, the PC Reach is not discontinued. I saw one on the showroom floor in Jakarta two weeks ago, and EWalker in Singapore has several on the floor on display. $1,999 buys one.

I can tell you the Dash offers a reassuring ride. If traditional diamond geometry and Lockjaw hinges don't reassure you, folding bikes ain't for you then.
