Not sure here. Brompton has a wheelbase of 104.5cm, within the bracket for a full size bikes. Folders typically have a shorter wheelbase giving rise to a squirrelly handling. Now this 20" 'Brompton' seems to have a wheelbase of the order of 118cm, there to squeeze in the 20" into the folded size. This is well beyond the bracket employed for full size bikes, presumably resulting in a klutzy sluggish handling.

Seems a long reach to the handlebars. Good for tall people but guessing by the seat angle that the rider is not tall.

Edit: that was the forum link. The one directly above (for Neuss) shows:
Web sites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for www.junik-hpv.de. The certificate is only valid for chronos.space4rent.de.

Well...perhaps are the certificates not valid for the wrong spelling of the page address (with https: )?
What do your browsers tell you once the "s" was removed from the links (https: )?
Edit: Obviously, it is a forum "feature" - the software will add automatically an "s" after recognizing the letters h t t p and there is no way to avoid that.

My Firefox browser reports "Error code: SEC_ERROR_BAD_SIGNATURE" for the SSL certificate. Other browsers may be less explicit, but that seems like a real problem to me.

Now, it wasn't necessary to actually quote me, so can you not do it again,...unless you manage to find a way to share the link WITHOUT having it become invalid.

GOT IT!!! But, if you look at the "copy and paste" link, it's http, NOT https. It's just not being allowed. No biggie,... I love the Mega Brommie all the same. It just might be too big for me (I believe it's custom designed for a rider who's WAYYYY over 6' tall, and I'm 5'11"), but it still looks AMAZING!

There's no reason that this bicycle couldn't be made
with a shorter toptube. Look how, in folded-mode,
the toptube of the 20" version is sticking out beyond the rear
wheel and compare it to where the TT of the 16" version ends.
The only reason that I can see for the extra length is to
accommodate the tall owner, not because the Brompton fold
system requires it.
If anyone sees that I'm wrong, please explain why. I don't own
a Brompton, have never even seen one in person.

You're confused. In my post, I acknowledged that the bicycle owner is tall. My post was addressing where someone implied that a 20" bicycle with the folding system that Brompton uses, would need to have an extra large frame.

Love the concept of the folding bike you can take just about anywhere. I haven't seen one and every time I go to their website they're either sold out or have a very limited selection. Guessing I'll have to wait until post covid

The tolerances for having the bike still fold like a Brompton are very tight. The hook off the front wheel must grab the chainstay behind the pusher. To the extent that I can tell, the particular wheelbase is the shortest you can afford for that with the 20" wheels. For full-size bikes and most manufacturers the wheelbase changes very little with bike size. If you want, you can email Juliane and ask. Obviously if you want to build a bike from scratch, you can do whatever you want, but history has not brought in, so far, anything seriously competing with Brompton in the tightness of the fold against the bike's riding ability.

By "pusher" do you mean pedal? The position of the front wheel can be accommodated by adding-to/subtracting-from, the toptube, on each side of the hinge in equal amounts. For instance, if 3" were subtracted from the toptube on each side of the hinge, the front wheel would still contact the chainstay in the same location, even though the TT is now 6" shorter. Perfectly do-able, you just have to subtract equal amounts.
