The video is very interesting !

It show the folding with plastic, slow and hard to operate locking mechanism (fork, stem/handlebar, locking of the folded front wheel). The rear triangle locking seems much better and better than the one of the Brompton.

I show that Helix rolls on its front wheel only, not both wheels.

It show the weight of 11.38kg without any accessory.

And the folded size of about 80x60x30cm without saddle and seatpost , maybe 90x70 with the saddle+seatpost, much bigger than a Brompton, similar to a Birdy.

The pentaclip offer a lot of saddle position adjustments, more than what the strange ugly potentially dangerous Helix seatpost offer, it is not a standard quill (changed recently), Brompton hinge are faster to operate than Helix locking mechanism and have proven to be reliable even with several daily fold/unfold which isn't case for Dahon hinge system for instance.

Now, who cares of old or new technology, what is important is the bike performances in any aspect (ride, fold, size, weight, utility, comfort...) and Brompton is the best in fold, size and utility, has very good riding and the superlight version weight less than Helix. The main weak points of the Brompton are its transmission (limited total range of 302%, too big spacing of about 25% between gears) but it is possible to mount an Alfine 11 or Rohloff Speedhub) and comfort due to high pressure, relatively narrow tires and poor rear suspension (but Helix has no suspension at all and also uses high pressure, relatively narrow tires).

Note hat titanium is also an "old" technology that appeared about 30 years ago for bike frames, didn't evolve at all (same alloy as 25-30 years ago) and is replaced since about 20 years by carbon and recently by... new stainless steel like Columbus XCR and Reynolds 953.!

The video show that the release of the Brompton hinge is quicker than the mechanism used by Helix ! Internal gear hub is better for a utility bike than external derailleur system becaus they are cleaner, last longer and need less maintenance.
You forgot the titanium fork and rear triangle of the superlight !

Indeed, Burke is handmade but is 3 times more expensive.
No, several BF models (there are and were a lot of BF models !) are as heavy and much bigger folded. BF also uses old technology !


Tyrell bikes are EXCEPTIONALLY well made (in Japan, no less), with hydroformed tubes, invisible welding lines and very expensive Kadowaki powder coat painting (which alone costs like $500, if done separately. I know a number of Brompton owners who let their frame powdercoated at Kadowaki). And they are still cheaper than Brompton.[/QUOTE]
You wrote "Being made in UK is never an advantage, unless you are a British citizen want to support local industry" why is it then important for Tyrell to be mad ein Japan ? Only the Ive is comparble to the Brompton, the others are more expensive (some very expensive).

Actually, the only unique selling proposition of Helix is its price but as you say, the production of a few first samples doesn't prove that Helix at its current price is a viable business.

Now, last point: why do I/we speak so much of the Brompton ? It is just because there is no other equivalent folder on the market ! The only two I could consider is the Tyrell Ive but it is too small for people of 1.80m or more and the Burke which isn't available in Europe and that I never could test (I have some doubts about its comfort).
