Two speed to six speed Brompton upgrade kit

Upgrade your two speed Brompton to six speed with our kit of Brompton parts

Note: Fitting of this kit will take some patience and mechanical knowledge

Since the introduction of the Brompton BLACK edition - this kit is now available in silver or black - this refers to the colour of the 3 speed BWR rear wheel 

With you in 3-5 working days

All the genuine Brompton parts required, including a Brompton/Sturmey Archer BWR (Brompton Wide ratio) rear wheel and cables etc.

Suitable for all Brompton handlebar types

Brompton 2 to 6 speed upgrade kit contents:

  • 1 x Rear wheel (double wall rim) with 3 speed Sturmey Archer hub - QRW3SS-BWR
  • 1 x Rim tape for double wall rim - QRIMTAPE-DW
  • 1 x Indicator chain - QGICH3-SA
  • 1 x Axle fittings for Sturmey Archer hub / wheel - QRW3NB-SA
  • 1 x 3 speed gear cable (M/P/S/H type) - QGCAB3A-M/P/S/H (Please state type)
  • 1 x Gear cable pulley - QCPULA
  • 1 x Cable anchor - QGCABANC-SA
  • 1 x Brompton 3 speed gear trigger - QGTRIGB3A
  • 1 x Sprocket set for 6 speed BWR - QRSPRSTACK-BWR6

2 to 6 speed Brompton upgrade instructions:

Step 1 - Check that you have all of the components as listed above
Step 2 - Prepare the new rear wheel

Install the rim tape

Install an inner tube and tyre (don't inflate the tyre yet as it's easier to install on the bike while deflated)

Install the sprocket set

Step 3 - Install the new rear wheel

Remove the old two - speed rear wheel

Install the new 3/6 speed wheel - this step will allow you to continue to use the bike as a 2 speed (although slightly heavier and in a higher gearing) - and you can go back to this if having any issues trying to figure out how the 3 speed mechanism works

Remove the gear indicator chain and keep safe

We also do this to quickly switch between 2 and 6 speeds when travelling (we sometimes want a 2 speed for lighter bike)

Step 4 - Install the 3 speed controls

You can install the 3 speed trigger, cable, gear cable pulley and cable anchor without connecting it - the bike will continue to run as a 2 speed with the new wheel

We velcro the cable anchor to the rear frame to keep it safe / from interfering with anything it shouldn't

Step 5 - Connect up the rear wheel

Insert the gear indicator chain

Connect the cable anchor to the gear indicator chain and adjust

Step 6 - Test ride 


Note:
Some instructions are included (with the wheel) - but you will need some mechanical / technical knowledge to do the upgrade. If you want to check out in advance, please contact us by clicking here

NOT FIT FOR PURPOSE

Inadequate instructions both with kit and on brompton website. 2 hours trying to find any info re fitting of cable anchorage

Quite an expensive kit, and would have made more sense to have bought a 6-speed bike in the first place, but my mint condition 2-speed couldn't handle the steep hills after moving. Kit contains all you need (if your crank sprocket is unworn) and is straightforward to fit if you're mechanically minded - there are no fitting instructions. Kust take a methodical approach and you won't go wrong. The upside of buying this kit is that I'm able to swap back to a 2-speed setup in future if my needs change again.
