One regarding Performance. You say that the X11 offers better performance. It's my own uneducated guess that's because the Helix only has a 34T chainring up front. The larger 42T chainring on the X11 will propel you faster with less effort and less cadence. Could the performance of the Helix be improved by replacing the chainring (let's go extreme) with a 58T chainring? Would that help? Also, would a larger chainring interfere with folding?

The second comment is something that I've read before. You're not the only person bringing up this idea. That is, under your Final Verdict, you said, "the ideal would be a cross between the X11 and the Helix. A 20" Helix with more tire options." Some people have said that the 24" inch wheel on the Helix is too large for a folding bike. Not sure if I understand why. The larger the wheel the more like a full -sized bike the Helix is. As far as folding is concerned, yes, 20" wheels would be more compact but would the ride quality of the Helix be compromised? Also, could you replace the 24" wheels with 20" wheels if you wanted or is this not possible?

I'm hoping, tomorrow, to take an X11 out for a test ride. So excited. What should I notice about the bike, both positives and negatives? It's a used bike. What should I ask the owner about the X11? Hopefully too, I will get a chance to test ride a Helix. There may be someone willing to show me their bike. I will definitely report back. I'm still not counting out getting a Brompton T-Line. I test rode that bike already. It's light, for sure, but was slow when facing a headwind and the jarring, bumpy ride was kind of painful. It's the perfect folder though.

Stay awesome! Any other thoughts are always welcome.
