That is bottomed out, with only 5mm above where the casters ride normally.
This is somewhere of where max extension could be, adjustable in this version.
I have been thinking about how the spring loaded center center will sit with nobody on it, guess it will have one end sticking up kinda like a onewheel lol. Also how you will get on and start going, curious about that.
A sturdy looking caster with a 8mm shaft and includes the correct spacers for a skate wheelâŚ
That $99 price includes 4 casters and a set of wheels that cost like $50. My main concern about it besides the price is that it includes a 70mm wheel and looks tight so the 72mm JMK Ride wheels might not fit.
So I emailed them to ask if I could buy only two casters without any wheels for hopefully like $25, and about the wheel size that fit.
The reply was to give them a call, Iâll have some answers to my questions.
I guess that caster is available elsewhere like on aliexpress but I just want more info about it for now.
Called them, 72mm wheels fit. Each one is $12, the caster is as strong as it looks he says.
Meant to say:
One of the problems might be the distance the wheel is from the center of the caster rotation axis. You can see here it is measured at about 3in. On both the freebord and leiftech/SBX it is much less like ~1in. One thing to consider is that the both of those design are constrained by fitting the center wheels as wide as possible under the deck so maybe there is not a real problem with this design.
Not really sure how this would affect the ability of the board to make transitions between sliding and returning to center. I feel like most of the control when riding comes from switching between the edges so as long as it can do that you should be good.
Getting rid of the extension springs⌠Want to try to use compression springs with some 3D printed retainers. This is to match the Freebord 5-X this version is planned to be used on (planning smaller version for Freebord 5/other) also because there is more room for springs on either side of the wheels, and this is where I want the springs pressing anyways.
These casters were selected with longboard wheels in mind and these JMK ride wheels are more skateboard sized at 43mm wide.
I am very tempted to design a 9mm wide belt drive for this caster. Would need a slip ring but whatevvvrr
it has been assembled. It works!!
(how do you like the hardware I found in my shed? @mmaner) I tried to save all the og hardware but it seems to be hiding.
I went out and gave it a ride, pretty good seems to function properly. The casters need to be moved closer to the hangers as I canât easily push without the back coming up and failing, have to do a funny hop-skip. Also when throwing it on the ground the casters will chatter very bad and stop, so some 3D printed cam thing like the freebords would be good. It would have to be much larger diameter to fit over the large caster base, not sure if that will work.
I donât have them on there very tight a bolt actually fell out while carrying it back the double nut didnât work.
Iâm not worried about bending the caster it has like 2mm of slop side to side. Hmm I wonder how one of those silicone riser pads would do on the caster
hey man
Iâm waiting on a 2nd hand freebord to arrive, and iâm thinking about electrifying it.
I plan on doing it the way the guy did his dual motorized ripstick on youtube. with the wires going through the 10mm bolt of the original caster and then to an aliexpress slipring.
inspired by your post I also ordered the JMK ride wheels.
If you get around to designing a pulley that is self centering on those wheels I would greatly apreciate it ! i kinda suck at 3d designing.
cheers

For sure I got SW open right now working on a new idea! I just need to take the JMK ride wheels off the freeboard and take better measurements now with digital calipers
got me inspired to make a design that is I think more akin to what the gentlemen I found on instagram designed, minus the custom slip ring but Iâm thinking about it.
hey, thanks man
I have to say that a suspended motorized wheel would be amazing, and if removable it would attain perfection.
I will have to wait to receive the board and hardware to really ponder on what i will want to do.
Iâm thinking about having two pairs of caster. the original with the freebord wheels to go downhill, and the custom made with Jmk wheels, pulley,motor and belt.
if the âwires going through the boltâ system works out ( instead of the original rivet) i think swapping between the two casters wouldnât be too complicated.
Of course I expect reality to get in the way.
<< Back to work >> as Mike Patey would say
I think I know the mod you are talking about where you cut the pin holding the caster assembly and replace it with a 12mm bolt or whatever, not sure where I saw it.
About the wires through the bolt idea- the capsule slip rings would stick up directly above the casters and thatâs kinda where your feet are. Will you just stand wider over them? Whatâs your plan?
Perhaps you could have the wires go through the center of a RC/3D printed universal joint so the slip ring can be mounted at 45/90 deg and farther inwards from where your feet go. Then have a plastic covering so you canât step on it, the covering could be part of an extra concave for your feet maybe.
