Pedal Sensors (PAS)
Universal Pedal Sensor For Bromptons
£35
Includes both magnetic disc and pedal sensor. Supplied with several variations, to fit pre-2013 and post-2013 Brompton’s.
If your Brompton bike doesn't fall within the range where the Brompton-specific magnetic discs fit, you can use the universal pedal sensor setup instead. If the gap between your bike's pedal arm and frame is 4mm or more, use the regular spacers. For a gap between 2mm and 4mm, use the thin spacer set. If the gap is less than 2mm, the magnetic disc can be used without spacers, but the arm must be used to secure it in place.
