I've looked! unfortunately (for me) I've been able to locate online only a few, short reviews. I'm interested in the Helix because it appears to have a relatively compact folded size with relatively light weight and "reasonable" diameter wheels. It also appeals to my sense of engineering aesthetics. The problem is that I'm old (73 ) with an old man's neck which requires me to seek out a relatively upright riding position and I'm wondering how the geometry of the Helix might fit my needs with or without bar +/or stem replacement (if such is even feasible). All thoughts appreciated!
