spambait11, by rear swing arm, does that mean the entire rear triangle or that small but very important helical hinge and/or mechanisms surrounding it?
Peter made it sound like it was mainly a welding issue for the entire rear triangle (because the geometry of the rear triangle made it complicated to weld), since he specifically wanted robot welding. Helix tried to contract out the welding, but the subcontractor wanted 7 figures and long lead times. So Helix looked at other options: "stamping, super plastic forming and then casting." These were the times when everyone was getting frustrated because we didn’t know the full-story for the delay. Eventually Helix settled on doing everything in-house, and we’re finally seeing the results.

The triangular supports for the rear swing arm are longer making the rear swing arm look much more, well, triangular which makes the overall design of the bike look more aesthetically pleasing. He’s also given the backers a Ti seatpost.

Looking forward to riding this bike!
