Brompton owners

What's the actual difference between an S and an H, besides the handlebar and cable length?

The overall stem height looks to be the same, just with a higher hinge on the H.

In which case isn't an H better if you want custom bars as you've got more room for the bars in the folded position?

Fold point for one.

Also angle of bend

Angle, folded position, weight, aesthetic, height.

So, I am shortly to cross over to the dark side and become a Brompton owner. Apart from having to learn the obvious things like the secret handshakes, I have one burning question...

Can anyone come with a solid recommendation on how to fix a U lock to a Brompton during riding? Obviously I'll mostly carry it with me but no way am I taking a bike out without a chunky ass mother fucker of a lock. I find these two ideas on 't web. All thoughts, or locations or even specific lock recommendations appreciated. and also

Thanks in advance.

locking a brompton? why? you can carry it anywhere ..

Because there will always be those situations where you potentially cannot take it with you. Swimming pool, cinema etc.

the only way I have tackled such things is by being utterly shameless .. the drivers get subsidised street space for parking their 2 tonne pieces of shit why cant a place accept a bike the size of a small briefcase ?

anyway, I use abus bordo on my full sized bike as a 2nd lock, I have seen lots of brompton riders mount it on the top tube.

I use a TiGr lock and it goes in the left pocket of my 'C' bag.

Edited to add - It is never locked up for longer than 5 minutes - literally, just dipping into a shop.

At this point I'm thinking of something uber chunky like an Abus granite X plus or a heavy weight kryptonite

Hello! Then you shouldn't ride there on a Brompton--they're theft magnets. Don't leave one locked up outside in London (if you are back in London).

Neither will help against well-equipped thieves. Take it inside or ride another bike there.

I sometimes lock my bike up in relatively safe areas if I'm popping in somewhere quick, particularly if the IT chair is fitted

I use a Bordo lock on it, it's permanently attached. Also used a cafe style lock on there for a bit of additional inconvenience

Hello indeed @Oliver Schick I'm partially back and tending to be in the UK for work for a few months at a time. My old beast is still in store (inaccessible) as I've nowhere to put it day to day. I'm getting fat(ter) and going crazy without a bike hence the Brompton.

Leaving it outside will always be a last resort, but I want to ensure that I've always got a lock for exactly those eventualities.

Yes, a Brompton obviously makes sense. I hope you never have to leave it outside!

See you at Easts sometime?

Very possibly.

Excellent.

Spotted on the A315 between Olympia and Hammersmith about 5:15 someone on a clear lacquer Brommy with the biggest chainring in the world. Anyone here?

So, does this mean that a P stem with S bars is the lowest front end for the aero-inclined rider who is flexible enough?

Slam the Brompton son.

I'll lock my Brompton up in Oz but wouldn't dream of doing it in London... Take it with you, explain you don't have a lock, easy...

Yes, have done multiple conversions, nice and low and keeps it long.

Harder to get a p stem now though!

Don’t leave it.

It won’t be there upon return. If I had more time I would take the challenge of I can take my Brompton into everywhere in London. There is not a door one cannot pass.

I'm not sure I'd fancy my chances at the typical West End theatre

Cloakroom? With all the prams and inexplicable massive parcels wrapped in clingfilm...

Customer of mine spotted someone angle-grinding the lock off her Brompton outside an office in Homerton at 11:30am a few weeks back. She managed to scare him off before he got through it.

I wouldn’t dream of leaving mine outside anywhere in London for more than 10-15 minutes.
