I ride a hub motor bike and it's a very active experience. In addition to pedaling and braking, I'm frequently adjusting throttle, gear and assist levels. It's not for everyone, but it's about as manual as you can get.
I've never ridden a Bosch but the main downside of my bike, a juiced ccs, is the ride is very stiff in the back even with a wider plush tire. The motor is too bulky and powerful for my needs I realize but there's not a ton of choice out there for a low cost athletic torque sensor class 3 commuter.
