One-way bearing inside motor pulley to improve coasting?

Does anyone have experience with putting a one-way bearing inside the motor pulley to improve coasting? Obviously I lose braking ability with the one-way but I'm looking to build a small 28-30 inch commuter board with a top speed of only 13-14mph, so it's not very fast at all. I can stop with my feet like I do with my regular boards.

How much drag is there on a belt driven e-board when you let off throttle?

Would epoxy be strong enough to hold the one way bearing inside the pulley?

In theory a one-way bearing would improve my watts/mile because I can coast further, anyone with experience on this?

Some Unite brand and other comparable scooter motors had clutched sprockets.

Needle roller clutches are very compact and effective, but they are specified to be pressed into steel housings of a rated minimum thickness. If you have a steel toothed belt sprocket, that would likely work if its diameter is big enough for the clutch that fits the motor shaft.

You could always get yourself a safe and legal street vehicle instead of a hazardous toy.

You should go hub motors..
