I'm having a Great Big Cargo Bike Sale! Only three ex-demo Riese & Muller cargo bikes left at big discounts.

Brompton G-Line Conversion Kits

Just ordered a new G-Line, and want more than the standard 8-speed hub gear and chain drive? No problem! I’ve got some ways to upgrade the G-Line:

  • Alfine-11 Hub: This is a simple upgrade, to change the 8-speed Alfine to the more efficient 11-speed, with a wider gear range. This kit includes a new rear wheel, fitting kit and shifter. £595 – Add To Cart
  • Rohloff 14-Speed Hub: This upgrade is a bit more complex, it comes with custom Rohloff replacement dropouts for the G-Line, a different tensioner, the Rohloff wheel, shifter etc. £1595 – Add To Cart
  • Belt Drive: The standard chain drive can be upgraded to a Gates belt drive, keeping the 8-speed Alfine hub, or upgrading the gearing as well. £395 – Add To Cart
  • Di2 Alfine Upgrade: An upgrade for the Alfine-11 gearing above, this adds electronic Di2 shifting instead of mechanical – cannot be combined with a belt drive. £495 – Add To Cart

All the kits can be fitted yourself, though the belt drive kit needs you to cut through the dropout – I’m happy to fit any of them here if you don’t want to do it!
