I’ve ridden the Specialized Turbo Como with the Brose motor and they are quite snappy. The upright position with the big tires is really comfortable to ride. A little low on power though (~550W peak) which can feel underwhelming when you’re used to having 900-1000W. The jury still seems to be out on the reliability of Brose motors. If you read the Specialized forum there are no shortage of examples of people having problems with them and it’s not really a user serviceable item. Throttles are really addictive once you’re used to them. Really helps in stop and go riding to get these 50-60lbs bikes back up to speed.
