We got an old Bob 3 wheel stroller from a family friend. Frame is a bit rusted and it's been thru some stuff, but it has been perfectly functional for us for the last 3 years. However, just recently, after taking it out of the car, one of the rear wheels fell off. Turns out one of the wheel release latches was completely loose and busted.
I was hoping there was some hacky ability to repair it - rather than throwing it out - envisioning grey market supplies or 3d printer parts or etc.
Instead, I found a website that sells official Bob parts and a replacement rear latch assembly and a video on how to install.

Less than 15 bucks later, (including shipping and tax) I now again have a perfectly functional stroller.

I know these strollers are pricey - but that really makes a difference in willingness to recommend these strollers in the future.

Also, FYI, if you're in need of a stroller wagon - the 3 seater Bob one is a good choice.
