Commander Mini Suspension Teardown
Vložit

- This is my first video concerning the Extreme Bull Commander Mini electric unicycle where I will be tearing down the suspension. I began this project to address the complaints of suspension stiffness & lack of sag that riders report. My next video will go into more specifics about suspension function, the reason for perceived stiffness & travel limitation, and an essentially free solution.
NOTE: I realized that this video does not mention that the cartridge sleeve is also attached with red loctite. In the next video I will show how I clamped it to remove. In this video pieces were loosely assembled & come apart far more easily than "in the wild." Stay tuned for part 2.

Sweeet vid, looks like everyone’s still patiently waiting for part 2 and I’m one of them, thanks 🙏🏼
Thanks for doing this, there aren't readily available videos out there to see in depth the hydraulic suspension teardown for a commander mini. Definitely looking forward to part 2!
Great video. Look forward to seeing how you make the shock work better in the next one.
Thank you! Also appreciate you mentioning previous mistakes as well as leaving these small mistakes in the video as there are the things everyone will have to deal with while tinkering
Yep, I screw up all the time! As I have been tangled up rebuilding the automatic transmission in my Ford Excursion (the reason I have temporarily stalled on the Mini) I have made a BUNCH of mistakes! In fact I just had to order a new pump-half as I forgot to put a steel round under a recessed surface while driving in a bushing. There is a thin lip of aluminum and it popped it right off! Great outfit where I had ordered the rebuilt pump, they selling me just the half I need for half price, shipped yesterday. In fact, the reason I was putting a bushing back in (the rebuilder had installed new bushings/seal) was that I knocked the old one out to enlarge a drain hole. It is a known issue that can lead to ATF leaking out past the converter. Enlarging a passage that sits directly under the seal allows the fluid to easily exit rather than getting forced through the seal with the pressure & flow are high. My new half won't have the bushing & seal already in, so I can drill the outlet and then CAREFULLY install the bushing.
I am always seeking to make things better, and given the labor in just removing & reinstalling the transmission in my driveway, I want a bulletproof build! Ford made multiple changes 'on the fly' with these, and over the past 20 yrs basically everything is well worked out in the aftermarket arena. Our EUCs change so quickly that only a few (the Master comes to mind) seem to really have much effort in improving them.
Thank you so much for the video, I have to leave you a comment for this well detailed and explained tear down🎉🎉🎉
Looking forward for the tutorial about how much spring to cut and how😂
Hopefully SOON! I have been preoccupied with other things (as I keep writing!) but am about to get back to it.
Thx for the info I will do it for my mini it’s been rough on legs and back bc of hard ride
Thanks for this video, can't wait to hear more about the modding process and how it affects the riding experience!
Me too! I have been so busy with other things, I haven't put it back together. Barely been on the A2, but hopefully this will change soon.
Really important video, and I hope the manufacturers take note. You're a really good teacher too. Good to have you aboard aye.
Also cool you mentioned EUC Adventures. Those Dutch guys just terrorize their wheels, and the cp mini had really shown through.
Glad you appreciate the video. Someone has passed my contact info on to Extreme Bull, I hope they do reach out. This is the most neglected wheel, and is SO CLOSE to being exceptional.
This video is very useful, thank you for sharing. I'm exciting to see next one.
One question: you have cut the spring 1 or 2 inch in an other video i thought! And is the suspension smoother and now better to adjust? Because i wheight 140-150 pounds and i dont know how to adjust the suspension. Can you do a video where you can Show US how to adjust the suspension please?The mini is a great wheel. Do you know,that the mini pedal dips in sharp corners? Or is this adjustable in the app? I'm new in the euc community.Thx greets from vienna.
Nice video. Very interesting.
great video thanks !
Hello randeuc, you have a idea how much olie you get out off the suspension.
Grtz Yogi
Hello! I admire your vigorous efforts to push your Mini as hard as possible! Volume - I managed to spill a bit from each shock when doing the teardown. I think it was something just over 100ml. If Extreme Bull would reach out, I would love to have dialogue with them. I have hoped to try different fluids and volume, but because of the work involved in the teardown, and the need to put it back together with RED loctite, that will be a bit of a project. It seems a slightly thicker fluid might be good, then leave rebound bleed OPEN. This would give more compression damping if needed. More oil => smaller air volume => more progression to rate.
Thank you for your video. Do you have an idea when you will make the following video?
I am pretty light guy and the suspension is really too stiff for everyday usage. Don't want to make a mistake, as I have no experience in modifying a suspension and will have a few days time in May.
Are there known compatible springs? Maybe dimensions to search for? Is the suspension from a known brand (making it easier to find pieces)?
Thank you!
I have looked for other springs. The stock spring is 234mm long, the one I cut is 220mm. OD of the spring is 1" (like 25.45-53 mm by my measurements). There is not identification on the suspension anywhere. As noted it really is nicely machined, and other than lacking a compression bypass (to adjust compression damping) the only problem is the spring. Now it is not particularly user serviceable, the Fastace units that LeaperKim uses are far easier to disassemble from videos I have seen. But they have been plagued with leaking seals and such., whereas that seems rare in our units. IF this were dialed in properly w/ spring rate, I don't think the difficulty with servicing would be such an issue. But I confess that thinking of going through repeated assembly/disassembly to play with viscosity of fluid & levels of fluid doesn't seem like fun. BTW: changing fluid level simply alters the amount of trapped air that acts like additional progressive springing.
@@RandEuc What type of oil would you begin with, and how much? Is it necessary to cut the spring on both end to achieve this length, or one side only would be sufficient?
"Stay tuned for part 2." :(
Patience, grasshopper 😎 Soon, I promise
@@RandEuc Amazing! Looking forward to it!
@4:38 having a difficult time understanding your idea you describe about a plastic self lubricating device attached to the suspension track. I wish you had done a better job of explaining that. Perhaps a diagram would be beneficial with conveying your proposal.
What I am referring to are the bronze inserts that are at the base, the steel rods slide through them. My point is that something easily swapped & inexpensive would be good. But E-Adventures recently posted a maintenance video where he was replacing bearings.
I have been stalled out on other things that have kept me from getting back to these videos, but more to come soon!
@@RandEuc the oil impregnated bushings? Yeah I'm still kinda lost on the mod idea but i guess it's not that important. I'll be sure to come back to check, thanks
Where is the tear down video your talking about, not the one from euc adventures... don't find it very helpful, he doesn't really explain anything only summarizes what he did
