Hub motors have their advantages, but they also have significant disadvantages.

1. You need lots of torque @ low RPM. This requires large diameter motors, or gear reduction.

2. They add significant unsprung weight (copper wire & magnets) - this amount of unsprung weight seriously inhibits responsive vertical motion.

3. Complex design, because you need to stuff both the motor and the brake components within the confines of a single wheel. A compact package would also likely create blistering heat problems.
