Brompton owners

The C and A are new names introduced in 2021 for the classic steel design, the A having various cheaper components. The P line is similar but has a Ti fork and a significantly different (also Ti) rear triangle that takes different gear options (such as the 4 speed derailleur).

The T-line introduced many redesigned parts and has very little in common with the older models, other than sharing a rear triangle with the P-line. The major frame parts are Titanium and it has carbon forks.

The G-line has 20 inch wheels, disc brakes and shares some superficial design choices with the T-line, but is steel with an aluminium fork.

The pre-2021 Titanium models are similar to the A and C line but their forks and rear triangles and some other small parts are Ti, but with no significant compatibility differences.

Before 2021 bikes were known by a 3 letter/number code indicating their handlebar shape, number of gears and rack/mudguard-having-ness. There was also a thing called a B75 which was a precursor of the A-line.

I need to collect kids on some of the days I’d ride - most likely a 2yo in a pushchair.

What PeteJChurchill also said.

If you are carrying the Brompton for a very short distance it works. Even 200 yards might annoy you/you will find the bike banging a tender part of your side so you might find it easier to either go home first or if the nursery are nice enough to let you stash the bike; but this does mean you have to drop-off the next morning or just come back for it if you can.

If your pushchair has the space for to 'stash' it, this might be easier. If you have a lightweight pushchair like a yoyo, then the only realistic option might be the roller rack and you 'push' the pushchair and the bike at the same time with the bike between you and the pushchair.

My little one has passed the pushchair stage; the only way I think it can be done is one hand on the pushchair and one hand on the unfolded bike, but definitely I would prefer the lightness of the T vs a C, even for 10 mins were I to carry.

Meant to @Gren.

Affordable (Heavy quotation marks).
Classic.
Premium (steel frame)
Top end (titanium frame).

Is how I remember. As for parts interchangeability, A and C are basically interchangeable, while P and T often do their own thing.

Thanks for this and other responses.

I do have a Zen, but the nursery buggy is different (Silver Cross - which is actually a lot better in most ways imo, but that’s for another thread). A key weakness of the SC, though, is that it can only be pushed two handed, unlike the Zen. So navigating the walk with the bike unfolded is out.

However, if the shoulder strap is short enough, I may be able to hang the bike over the handles and the bike not touch the ground. So that may be an option.

I do think I will probably just not do this under any circumstance and just go home first, for the sake of an extra ten minutes, but still thanks for the discussion to help my reasoning!

I’m decided on the C-Line with low bars, and am going to get the front bag and some tan walls and spare inners. Deliberating on whether to also get the Brooks all weather saddle, but think I’ll likely stick an Arione or Flite on there. Will be running Atac pedals.

Keen to get some ‘commuting’ gear, rather than be fully lycra’d. Is there go-to non-cycling specific stuff worth checking out? M&S, Uniqlo etc?

Carbon bars and crankset too.

Probably too flash as a daily, that said, it's the one I'll get if I do upgrade my current one.

The T-line introduced many redesigned parts and has very little in common with the older models, other than sharing a rear triangle with the P-line. The major frame parts are Titanium and it has carbon forks.

I think the counterweight with your little one might imbalance the pram. Even taking your hands off for a split second.. be very careful here please!

I have no idea on SC prams but those days are behind me...

As for commuting gear - decathlon is your friend but if you have full cleats on why not full kit w? Be that guy at the nursery pick up.

Continental Contact urban is the forum approved tyre (he says without authority); and yes available in tan-wall.

Yeah, I think I’ll discount the idea of it entirely.

I have no qualms about fkw’ing it. Used to do it everyday. That gear may be a struggle to get into until I’ve done a month or two back on the bike. Decathlon a great shout! And thanks for the tip on those tyres.
