Hi, I use both a BBS02 and a rear hub motor. They are used to commute, shopping and with a trailer.
In my opinion the BBS02 is improved with a gear sensor, this adds more cost to the purchase. The BBS02 cannot be used with standard chainrings unless you use an adapter which again more cost. The BBS02 is a great system but in my opinion it is not perfect out of the box.
Hub motors can be used with standard chainrings and I feel they don't require any additional equipment to tweek the system. If I was to buy for the first time again I would buy a rear hub motor with a frame battery.
As you can see people prefer different types and are passionate about this. People will read this post and agree / disagree with my all/some of my comments.
Both systems require the purchase of tools, BBS02 will require a locking spanner, a hub motor will require a file (I used a 10.2mm round file).
If possible try both types, most of all, enjoy using whatever system you buy.
