To freewheel means to ride a bike without having to pedal to propel oneself.
To ride a bike without holding on to the handlebars means what it means, namely, to ride a bike without keeping your hands on the handlebars.
What is your opinion.
I agree entirely with your opinion. I think there is a word for cycling without your hands on the handlebars but I can't remember it at the moment!
Edit - I could be wrong about there being a word for it. Google has only been able to come up with "cycling no-hands/handed" or "no-handed cycling".
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
