I don't know about you all being in UK, but here in Turkey situation with supply chain is awful. Dealers say they no longer can order bikes to their requirements but just receive whatever Brompton sends their way and most of what they need is not sent at all.
Same goes for spare parts, at leat some of them.(....) Brompton is famous for supporting all of it's models and constant availability of all spare parts. At least that's the impression I had from Brompton reviews which influenced me partly into decision to buy one.
There's a lot of aspects coming together at the moment.
1. Since a couple of years Brompton transforms to a more modern company. They announced a massive growth plan back in about 2016 when moving to the new factory and even a couple of years before they started to change their image bit by bit to more of an emotional fashion item and less of the rational engineer's product that they used to be. Necessary for the planned growth to reach a broader audience but with consequences for the attitude and the priorities of the company.
2. During this process they also focussed more on efficiency and profits. One visible consequence is the delisting of spare parts specific for older bikes like the 15t sprocket for the Sachs/SRAM hubs. A shame, if you ask me - it renders a perfectly working bike (or at least it's rear wheel) useless only a bit more than 10 years after production because a 3€ part is no longer available. There are way more examples of specific pars no longer avail, however, due to the backwards compatibility you can typically upgrade an older bike with newer components though this is often more expensive than necessary. The other visible bit of that strategy is the elimination of variability: Just one rear damper for all instead of a hard and a soft one. Identical brakes front and rear instead of different ones. Again, there are more examples. This limit the necessary inventory, rises efficiency and profits but has in itself typically no negative impact on the users.
3. Already a couple of years ago Brompton stopped the free sale of frame parts in the UK - they were only available to be fitted at a dealer's workshop, not for fitting yourself. This seems still to be limited mainly to the UK but with Brompton taking over the distribution from local distributers in the various countries and regions more and more it is possible that it will become the standard.
4. Brexit brought challenges in terms of getting sufficient amounts of parts from the suppliers all over the world. To cover this foreseable risk Brompton built up extra stock as a Buffer.
5. Covid brought a massive rise in demand, so Brompton used this extra stock to serve the additional demand in the first hand instead of keeping it as a buffer. Consequence: Brexit and Covid based issues in the supply chain aggregated and Brompton is low on parts stock. This is i.e. probably the reason why the bikes in their online shop are fitted with Brooks C17 saddles instead of the usual Brompton saddles.
6. To make things worse, Brompton implemented a new ERP-system, a project running already for a while. Foreseeable (and no surprise for anyone that has ever been affected by such a project) this led to a lot of hickups including a lot of dealers not being able to order bikes or parts due to not being experienced with the new system plus the system not working properly anyway. A bit of a chaotic situation.
7. In several parts of the world Brompton took over distribution themselves from the local importers, i.e. in the DACH region in December 2020 from the importer for 30 years. As a consequence they needed to build up new trust to the dealers, new processes and new structures from stratch. Which probably will have fired back to the factory partly as well.
8. Due to the masssive rise in demand plus the Covid caused chaotic lockdowns all over the world Brompton needed to reinvent distribution and sales: There was way more demand than they could cover and at the same time shops were forced to close more or less randomly. So they fast forwarded their online sales and things like pick and collect. Again, this will have had effects in the factory. Also they would have to make tough decisions which demand to fulfill and which to deny in terms of dealers or countries.
9. The massive short-term scale-up in production to more than 100.000 bikes a year needed more people, more materials and gave load on all processes. Probably did not run totally smoothly and produced quality issues, unrealiability and unhappyness.
This all aggregated is a bit of a mess. Partly home-grown, partly externally caused, partly bad luck. All put together a tough job to fix and clearly not a stituation where customers can be happy with ease. We'll have to see what the situation looks like in a year or two.
