my grandson would be riding with me but he has a cast on his arm would he still be able to ride

Agreed. I did not see that on the restricted conditions list.

I don't see why he couldn't. The brake handles are on both sides, so as long as he can use one arm, I don't see a problem.

Yes

Yes, as long as he is a passenger and not the driver.

I would check with manager first im not postive. it would be a liability for them

He'll be fine it's not a rule you can't

He will be fine. It is a sweet ride.

I would imagine he could. I saw a guy on crutches ride.
