Re: frustrated mom
Yup! Bikes of this sort tend to frustrate newbies. But then there comes a day when you 'get it'. And they're very loveable after that.
Have your son come to this site and start reading. Any headline that looks interesting. In no time at all he'll start seeing info that pertains to his particular bike. Like one of the guys above stated, very basic tools will get him through it.
He'll find himself understanding and fixing his own bike.
And then he'll be off and running.
