Applicable for A and C Line Brompton bikes only and all bikes made before 2021. Rolling mode allows easy transport of your Brompton when in train stations, supermarkets and open office spaces. Your Brompton, when part folded, can be carried or rolled whilst in Rolling mode. In this video we will show you how to push or pull your Brompton, which minimises carrying fatigue and excess exertion. This technique applies to bikes with or without a rack but for better stability we suggest the use of a rear rack or upgrading to the Advance Roller or Eazy wheels.
