I’ve built myself a manual machine to play with. I’ll post some video when I figure out where I packed my GoPro cameras.
Looks neat, Ian!
Jeff, did you create the new thread name?
Cool! I’ve been wanting to make one.
Thanks! The plans I used are simpler than some of the others I’ve seen. I had roughly measured what I needed for the fat bike, then extended his brace measurements by about an inch or so each to account for the bigger tire. I’m also using a wider base plate (2x8) to accommodate the fatty, but a 2x10 might have been better to give a little extra breathing room for the side braces.
I’m happy to help out sometime if you want to build one. Hopefully I’ll get good enough that I can then sell/pass on my machine.
EDIT: The beauty of designing this for a fat tire is that, in theory, it should be easy to drop in a shim to handle a narrower tire.
I’ll start off with one of these and work my way up
Hmm …how to make a bunny hop machine…
He does include plans for kicker ramps: https://www.lunchridemtb.com/plans
If you find something for a bunny hop trainer, let me know!
Video, as promised. Still early yet, I expect a couple of weeks at least before I’m ready to try with the chain off.
Update: really think I’m making progress.
Just in case things are getting too easy…
Even he can’t believe he did it!
