@ascentale @semitones @bikenite #BikeNite A3: Yes, I let a bike shop convert my Brompton into an e-bike using the friction wheel based #Velospeeder conversion kit. In contrast to most friction wheel kits it does not propel the tire but the rim from both sides: https://www.velogical-engineering.com/velospeeder/product-information/?lang=en

Depending on engine and battery size the system weighs between 1.2kg and 2.5kg.

I'm quite happy with it, but wet rims cause slipping and with rims worn down by rim brakes can make it stop working completely.
