    Just some thoughts,

    The rear motor arms could be shortened by 150mm each as they are not used for Roll.

    We could use a 20:1 worm gear box with a 3:1 to 6:1 timing pulley connector system to connect the dc motor to the worm gear box. By simply changing the orange pulley, we have an easily adjustable system for fine tuning the simulator to the rider’s weight and should help to address the free wheel issue.
    Something like this -

    That's right. But the killer for the common DIYer is the price for those wormgear drives.

    The problem I was having was with the prices of pulleys. The large one in the original plan was always expensive and I needed two of them for every motor. Then you add 4 fixed UCF bearings, 2 axels and belts it costs the same or more that a worm gear box.

    I believe I could get the worm gear box for about $150 USD on eBay. Add the $75 USD motor, and under $50 USD for pulleys and a belt. This comes to about $275 USD an actuator. Not too bad considering what we are building.
