New bike Friction Drive kit

Looks very novel design, can friction drive become practical? :wink:
Friction wheels do not leave the tire, relying on the motor itself to reduce resistance.
No exposed motor wire, small size, no noise.
The first model friction wheel can't leave the tire, but it's very small.
The second model friction wheel can leave the tire.
