At CycleReCycle(
https://www.cycle-re-cycle-swm.org/) we have a policy of not giving away bikes free to anyone. People have to earn them.
Our L'EarnABike program geared primarily for young people 9 to 19 teaches basic bike mechanics, maintenance, and repair, and safe street riding. It is often the first vocational type training many of these young people have ever had. Many have no experience using tools, the correct tool or using it properly.. Importantly by design the program also teaches a number of social skills along the way. These include how to ask for and give help, how to have a polite conversation with someone perhaps from a different culture or ethnicity, looking someone in the eye and addressing them by name, how to show up on time as scheduled, how to dress and behave in a work environment . We don't put up with foul language and have a strict anti-bullying policy. We give quite a few 1st job referrals to young grads.
One thing we see is when a group of kids on bikes come together to our shop the ones who have been through our program have far better maintained bikes even though they have no more money than the others. They've learned how to take care of them . They are also the ones who will put their bike in a rack or stand it up against something and lock it. The others tend to jump off and leave them crashed wherever they fall.
