M is the right height for me, but I chose to change the brake levers from theirs
to a more common (cantilever pull) MTB..

and needed a longer front cable because theirs angled down the cable path,
where the others go straight across ..

Rear seemed to be OK, front rubbed of paint on the fork, from shorter U loop,
so I made it longer..

H mast is about S height , but the hinge design change allows a M bar to be higher,
while not hitting the ground when folded.. so a good candidate for a riser bar,
that will actually be lower than the M bar , and leaving cable slack..

Red housing is easy enough to find and cut to fit, but what's the situation with inner wires? Are they normal shifter/brake stuff, or will I need to buy a Brompton M set?
You don’t need to buy the Brompton set, it’s easy enough to make your own, but I couldn’t be buggered.

Could just work out. A couple of years ago I did a similar conversion on a 2008 S-Brompton, adding a riser bar that was about 2,5 cm higher than the stock S but a bit wider (the stock S at this time had 48cm width while my retrofitted bar had about the same width or slightly more than the current S bars). It worked out with the stock cables, just about. Anything higher or wider would have needed longer cables. However, at that time these were the old style brake levers and the old style shifters, so things may have changed since with the current setup. However: I'd give it a try and have hopes that you won't need longer cables (if you stick to an inch of rise).

Brake cables are normal ones, the new shifter cables are normal ones as well but I think a bit uncommon regarding the nipple size - do not have the exact sizing at hand currently and therefore not totally sure. In any way you can - if necessary - buy the inner shifter cables for an M, P or H model and cut them to the appropriate length if you have trouble finding the correct ones. Outer cables are Jagwire, those are available aftermarket in red as well.

Seems they used a Coated cable, for a while , (not owning a 2017 bike)

but where it had to follow a bend, like going to the front brake,
the coating goes away ..

but the liner in the housing is more durable..

I'll let y'all know how it goes, I ordered my BWC Edition last night. I was super indecisive about which model I really wanted and BWCs started dropping off websites. I discovered there's only 20 in the US this year, so I jumped. I can't wait!

Congratulations on the new bike purchase Joe. Did they say how long it was going to take to receive your bike?

I think I'll have to pass on this S2.
Depends on whether you want to stick with the "boring black" Brompton cables or try Jagwires or other brands (in some funky colors), as well as try another stem color (maybe even a Raw Lacquer/Nickel stem if you can find one). I'd take it as an opportunity to personalize the bike, even though it might cost you extra.

The NYCe Wheels site estimates 1-5 days to get it on a truck, but I won't know anything for sure 'til they open Monday. I sent a note asking for a gear reduction so that's going to be time swapping a new chainring and shortening the chain.

I too will offer my congrats! That edition reminds me of Evel Knievel- a childhood hero of mine.

(My on-order Tempest Blue S6L otoh reminds me of Clark Kent....)

HA! I just watched Travis Pastrana do the Evel jump in Vegas tonight. It was cool!

I'll post pics of the new bike in its own thread, this old one with the misspelled title has gotten confusing.

That's not to bad, at least the bike is in stock. I thought you might have ordered from Brompton and that wait can be quite long. Looking forward to your new thread when you receive the bike.

you’ll be fine on S. I put P type stem on mine which is lower than S with a slight riser carbon bar, but will probably swap in a set of flat bars.

Theador, I suspect you're right. I like the look and vibe of the bike with flat bars and Kojak tires - it's supposed to replicate a BWC racer, after all - and its main use for me will be shopping runs and popping it out of the car to go for some shortish rides. I'm not touring on it, so getting the bars in an "all day" position isn't a priority..I think it'll be great as is. I should have it in a few days!

That special edition Brompton youre waiting on is, can I say it?....Badass!

Im a bit envious, but my much ruminated about, much anticpated, Tempest Blue S6L is closer now than its ever been....however in the annals of Brompton history the BWC edition will be a much more interesting bike.

I cant wait to see your pictures Joe and Im certain you’ll enjoy every moment on that unique bike!

The Tempest Blue is cool, too..it's one of my favorite Brompton colors. We'll both be cool! ;-)

My wife and I have ridden our Vespas to some crazy places, where the adventure bike and hard-core Harley riders typically only go. When you pull up in Shoshone California, or in the middle of Death Valley amongst the hardcore, being on a lowly scooter is suddlenly elevated to “cool”status.

I feel that way about weird little clown bikes...(and the Bromptons even have bigger wheels than Vespas do!)

You know what you gotta do. You gotta carry your Brompton on your Vespa!
