Sure. They're just bikes. They're meant to be ridden.
I let the neighbor kid ride one of my bikes when he was home from college for the summer a few years ago and just getting into cycling. The kid rode that bike 3,500 miles that summer including a few rides with me. He crashed a few times so it was in pretty rough shape when I got it back.
One time I brought a bike to a 1000k for one of the volunteers to ride during the day while he was waiting for the riders to come in. I had never met him before I gave him my bike.
I gave my daughter one of my bikes to ride while she's at university. She keeps it outside so it won't be nearly as nice when I get it back as it was when I gave it to her. It has dynamo lighting and she rode it with the front qr undone so all the wiring got wrapped around the axle and I had to rewire the whole thing a few weeks ago.
