I have a 13 (bday the 15th) yr old who's out grown his 2nd bike. He's on the spectrum and doesn't ride a standard bicycle. Resources and funding was used for last 2 bikes .... He outgrown his last one and tire goes flat because he's heavier then when we got it 3 Summers ago. And I'm aiming for 2 person bc I can't tag along hold>ng the handlebar type thing on the back of his seat anymore he pedals too fast lol. I've been looking at a few and I got my eye on but they are definitely costly. Single mom I cannot afford on my own. If anyone knows of or has used their own and have any recommendations please let me know! :)
