I recently decided to upgrade the headlight on my Brompton Electric bike to the Cyo Premium E. I followed https://www.youtube.com/watch?v=osCbgMQwlY0 but found the video lacking in detail, so this guide goes into more depth on the parts and procedure needed.
The main difficulty with this upgrade is that the Cyo headlight does not come with the Molex connector used on the stock Brompton headlight, so you'll need to either install the connector on the new light yourself, or remove both sides of the original connector and solder the wires together. I went with the former approach, as I found it a bit "cleaner", and avoids modifying the battery side of the wiring.
