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.
Check it like any other used bike. Pay special attention to the hinge and check that it folds well, with no damage or cracks on that part. If you have the slightest doubt, don't buy it. Of course, check that the original parts have not been replaced and work well. You should immediately see that it's a fast bike.
This reminds me that a few (many?) years ago there was a Tern scandal about faulty hinges and many people vowed never to buy a Tern again. I have never had a problem with the X11.
A Helix was customized for Hong Kong and its hills and I noted these parts: cassette E-Thirteen XCX Plus 11s Sram XD 9-42 with a rear derailleur Shimano SLX M7000 11V.
