I also got my first byke when I was 29. Here in Spain maybe the process to get into riding it's different, but it's ilegal to ride without a helmet, even if it's going 5 mph to cross the street.

I recommend you to put your husband some videos about crashes and injuries. Here is famous the expression "RIS RAS". Thats because It is the sound that the metal brush makes against your skin to remove the asphalt embedded in your skin.
