I was able to test ride a founders' samurai with a configuration equivalent to the base. I was very impressed! Smooth, quiet, and comfortable. I was expecting a lot more noise from the motor but it wasn't bad. I was able to hit and maintain 20 VERY easily with the enviolo. Shifting took some wrist effort so that would be an issue for some bit fine for me.
I wish I tried to hit and maintain max speed but my test trail didn't have a long straight away. This would be my only concern with the enviolo as the rohlhoff has more gear range.
I think there is incredible value in the base config, especially with the early bird pricing. However, after adding a second battery you might be tantalizingly close to the premium model with E14 and a range of other upgrades.
