Pedal sensor
the system
Here's how it works...
01
Start pedalling!
Once the Kit is successfully installed, turn it on and start pedalling as usual. You’ll notice the red LED on the pedal sensor flashing! This happens as the magnets on the magnetic disc pass by the sensor, signalling to the system that you're peddling. For this to work properly, make sure the gap is small enough for the magnetic field to be detected.
02
Info gets sent to the controller
The motor controller regulates the flow of electricity from the Power Pack to the motor wheel, controlling speed and torque based on rider input from sensors like the throttle or pedal-assist. It ensures smooth operation, monitors system performance, and protects the motor from electrical overloads. The GO controller is integrated directly into the Power Pack and within the mount for the AIR Kits.
03
Motor wheel gets supplied with power
The motor wheel houses the motor that converts electrical energy from the Power Pack into mechanical energy to propel the bike forward with 250W of power!

Smart Detection
Senses as you pedal
The Swytch Kit uses peddling information to stay compliant with regulations. The pedal sensor, one of the three core components to the kit, accurately detects when you pedal and when power is given. Watch the video to hear from our CTO, Dmitro, as he explains how it works and demonstrates the installation.
CLIP-ON
Fits down by the pedals
Designed by Swytch, our pedal sensors are built to easily clip together, making installation a breeze.
Connectivity
Works using magnets
To ensure the pedal sensor detects your peddling, make sure the distance is 2mm or less.
Three Options
Comes in a few options
Select from three pedal sensor options with your kit purchase: standard (most bikes), universal (fits all), or integrated (for select bikes).
Brompton specific
Fits effortlessly
We also offer two Brompton-specific magnetic disc variations, compatible with any Brompton – fitting the crank perfectly.

Frequently Asked Questions
Got a question?
How do I fit the integrated pedal sensor?
Can I exchange the pedal sensor I received with my kit for a different option and pay the difference?
Unfortunately, this option is not available. However, if you purchased the standard pedal sensor and need the universal option (with the arm), you can buy our upgrade set, which includes the arm and an additional set of spacers. If you purchased the kit with an integrated sensor and would prefer the standard or universal pedal sensor, you’ll need to contact our team or purchase it through our online shop. If you Kit has not yet been dispatched then we might be able to assist you.
Does the pedal sensor work in all weather conditions?
Yes, but if you’re cycling through muddy conditions, make sure to clean the disc and sensor regularly to ensure the magnetic signal is still being detected. Also, keep in mind that mud could shift the disc or sensor, so be sure to secure them tightly with cable ties.
What does working surface mean on the magnetic disc?
This side of the magnetic disc should face the sensor while you pedal. If it’s reversed, the sensor won’t function properly.
My pedal sensor is not working what is the issue?
The most common issue is that the distance between the disc and sensor is either too wide or misaligned. Please refer to the instruction manual for a detailed guide on how the pedal sensor should be fitted. If you have an unusual bike setup with a gap too small to fit the sensor, you can use pliers to remove the pivot plate, reducing the space – this will not void your warranty. Read more information here.
What tools do I need to fit the pedal sensor?
For the standard, universal, or Brompton pedal sensor, all you need is a pair of scissors to trim the cable ties. For the Brompton specific magnetic discs you will need a 2.5mm Allen key – the manual for this is here. For the integrated option, you’ll need a bottom bracket remover to take off the crank arm. This tool is available in our shop as part of our toolkit.
I don’t have my bike with me – how do I choose the right pedal sensor?
We recommend the universal pedal sensor, as it fits any bike and offers a hassle-free setup. Alternatively, the standard option is slightly more affordable, but if crank space is limited, you may need to purchase our arm upgrade from our shop. This arm secures the magnetic disc to your pedal arm without requiring a tight fit between the disc pieces.
Do Brompton owners automatically receive a Brompton-specific pedal sensor, or do they need to choose between the standard, universal, or integrated options?
In the order portal Brompton customers will automatically receive the Brompton-specific pedal sensor (PAS-BRO) due to the wheel size that has been selected – along with the standard magnetic disc or universal magnetic disc. If they choose the integrated option, they will receive only the integrated sensor.
Can I choose a pedal sensor when purchasing the Swytch kit?
Yes, when purchasing your Swytch kit, you can select from three pedal sensor options: standard, universal, or integrated, depending on your bike model.
