• Can I fold my folding bike with it installed?

  Yes, absolutely. With either the MAX or MAX+/MAX++ Kits, you can mount the Kit to either the handlebar or the front luggage block and still fold your Brompton as usual.

  If you choose to mount it on the handlebars facing forward, please note that you'll need to unclip the MAX+ or MAX++ before folding, due to their larger size. The standard MAX can remain clipped in when folding, as it's more compact.

  We also offer Bro Blocks, which let you mount the Kit to the front luggage block for improved weight distribution and handling.

• How long does the kit take to install?

  Most of our customers with basic bike experience, such as changing tyres and inner tubes, usually complete the installation in around 30 minutes. If you're less familiar with bike maintenance, it may take 45 to 60 minutes depending on your bike and the kit.

• Does the MAX+ Kit work better in colder temperatures?

  You will be fine to use your Swytch bike on the occasional Winter day but we recommend not to frequently ride it in below -5 degrees Celsius. Our Quality Control Testing did include performance tests at low temperatures. However, all lithium-ion batteries are impacted by temperature. You may have experienced this phenomenon if you've left a mobile phone or laptop in a car at night and found it totally drained the next morning. This is due to a chemical reaction caused by the cold resulting in faster discharge and/or a corresponding loss of battery life.
  Extremities in weather conditions may affect the Power Pack. The kit should not be charged if it is below 0 degrees Celsius and we recommend you do not store the Power Pack below -10 degrees C.

• What happened to the AIR Power Pack option?

  As of April 2025, AIR Power Packs are no longer available on our website. However, they remain in stock at over 100 bike shop retailers across the country.

• 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. 

• 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.

• Do I have to use a pedal sensor, what about just using a throttle?

  Depending on local laws and the region your kit is sold in, a pedal sensor may be required if throttles are restricted. In the US, where throttles are legal, you can use the throttle without a pedal sensor. In the UK, the throttle functions as a boost, increasing your pedal assist (PAS) to the highest level (Level 5) while peddling, providing extra power when riding in a lower setting or without a display in standard power mode.
