Help to get my sons bike fixed 67650 Campaign

My son got his first motor bike to get to work and back on his own. 

He was so exited, for the first time he had something of his own. Just 3 days later he went to work and the back wheel broke inside. 

We are struggling at this point in time and can't assist him with repairs. I'm asking if any one is willing and able to contribute towards getting his bike back on the road again. We are residing on a small holding and in the morning he must walk to work. 

He is a hard working kid that does not stay off work. 

He lost his father at the age of 11 and are really trying his best. He also dont work for alot of money in the month and must still pay off the motorbike with his weekley pay.  On the 5th of March 2024 he must also see doctors about varicose vains and circulation issues in legs. He is only 19 years of age. Please if there is anyone who can help him.
