I swapped the 50T for a 44T chainring on my M6R which suits my riding style much better and find the gears much more useable - I use them all now. This is my casual, utility, shopping bike.
I also have an S2E that I initially picked up for my wife. I swapped the 54T on that for the 50T I took of the M6R and again, we both find that much more useable.
In fact, there is a surprising difference on how these 2 bikes ride - the S2E is a chuckable, fun, lightweight(ish) little thing and reminds me so much of riding a bike when I was a kid. The only restriction with it is the size of front bag you can put on it, but I’ve got the other Brommie for that.
