surely if it already had a drum brake installed the fork would be designed (at the very least) to handle some force in that area?

This was my thinking , the Swytch motor is a fairly gentle power application too, it’s not like the jet power you get with a Bafang.

Drum brakes don't kick like a disc does. If you look at the fork crown to fork leg intersection, its done in just about the cheapest way possible. Suitable for v brakes forces and normal riding, not for a hub motor. been a few failures on brompton forks (they are lugged and built well enough) where folk have put them swytch kits on them.

Would excersize caution putting a front wheel motor on a fork of that construction type. Send an email to Pashley and ask if its OK, as a mechanic I would say no, unless somehow the crown/lug engages a long way into the fork leg. Its not as bad as old BSA suicide forks of the 50-80's, but I would ask the question to them.
