I think Mojo’s are a really nice frame. There are some issues but they are more detailing issues eg the cable guides etc. Some people sy that they are quite short but the large feels a pretty good fit for me but then I have long legs and a short upper body. Recently my forks died so they are getting rebuilt by TF. Can’t wait to get the forks back.
I don’t think bad bikes really exist per say. The best for enduro though must surely be the s works enduro with a cc db air. That will be my next frame.
