Liked it so much bought two.
My first conversion was a 20” Rear Drive for a Bike Friday. Really liked overall performance but sold the bike. Now have a 16” Brompton front wheel. The newest crank speed sensor works but is easy to knock out of alignment. Think the old style might be better. Run the Brompton with power off or Level One, sometimes putting in Level Three for s long stiff hill. Great support when I needed a part.
