Brompton's are awesome. For anyone considering going with an electric Brompton I have a suggestion. Just buy a base Brompton, whichever model you like, and add a Swytch electric bike kit. It has worked great for me, and in some ways better than my electric Brompton did, and save a ton of money. They have them for other bikes. I bought in when they did crowdfunding with a first gen for one bike. Then bought a few more with the 2nd gen, and now they are on the 3rd gen. Mine are still working great and takes about an hour to install. They have them for almost all bikes.
