I've owned Bromptons since 2014, with 3 bikes at my max. All of the bikes are 2014 Bromptons.

Since then I've collected a TON of spare parts (both original and third party), and I'm hoping I will have most of the parts necessary for the upgrade.

Here is a rough list of parts I think I might need for the upgrade, most of which I should have buried somewhere:

1. 2-spd shifter (yes)
2. BWR Hub wheel (yes)
3. 2/6-spd Chain tensioner (yes)
4. Chain pusher (likely)
5. Dog leg (likely)
6. 3/32" Chain (likely)
7. Shifter cables (likely)
8. Screws (maybe)

Am I missing anything else? My BWR Hub wheel has lain unused for more than 1.5 years, kept indoors but I wonder if it's going to work okay after installing.

Any advice would be appreciated. Thanks.

I cant hand hold on this, over the internet, just get started.. problem solve as you go along..


I took a different approach, 3 more speeds in low range, with a 2 speed geared crankset...

Thanks for the reply... just taking it slow since I got other bikes to tide me over.

Looks like all I will need is the chain pusher, derailleur spring and dog leg and barring anymore surprises, I'll have my M6E within a week.

Do you have the cogs?

I think Brompton's 2 speed uses the cable 'backwards'

the head in the back, the cut end in the shifter, on the handlebars.

the company likely has assembly information..

Yes the 6 speed wheel is complete with everything.

Interesting. Will check it. Thanks!

This was the case until 2016. From 2017 on with the new shifters it is the other way round (as with normal bikes).

OK ... I'm not a Brompton dealer..
