This bike should have a real 11s cassette + real derailleur just like Helix.
For the frame of Helix, 1kg more is a lot, the bigger wheel size has an influence on the folded size and on the wheel weight but has no influence on the frame weight because the wheelbase and frame sizes are similar whatever the wheel size.
For the price, Helix is sold online only by its manufacturer, there are no resellers, no after sale support other than the factory located in Canada. Its not comparable with Brompton that has a worldwide network of resellers providing after sale support, warranty, maintenance, spare parts...
Depending were you live, there are taxes to add to the price of Helix.
I also don't favor IGH. But on 349 wheels, you need an IGH to get an overdrive for a tall enough top gear, unless perhaps you use a rear hub with 9 tooth high, special. This was the driver for me doing 20"/406 wheel for my occasional-folder, 50-11 gets me 85 gear inches which is adequate for pedaling down a gentle grade or with the wind at my back, I don't need higher. But it's bulky folded, so if I go credit card touring in Asia, I'll probably fly over there, buy a Brompnot copy at 1/3 the price and no $300 shipping cost, ride it around in cities, bring it back home. But for my daily townie, it's 20" and all derailleurs.
