MTEN4 speed wobbles


zigro

Recommended Posts

Hello, new EUC rider, 175 lbs. I just got MTEN4 and have tire pressure set to 44PSI, get small speed wobbles at about 14MPH and bigger speed wobbles when braking at around 12-14MPH.

Got fairing side plates on order so I can make power pads, any other suggestions?

 Thanks

Hi, welcome to the forum. New riders experience wobbles. Even experienced riders get wobbles.

Little wheels are prone to wobbles. Take it easy, get some miles under your belt. Maybe run a little less tire pressure.

Best,

I wouldn't bother with power pads - wheels that small don't really need 'em... and you risk overpowering the wheel much more easily if you lean too hard into them. From the reviews I read when that machine came out it does have quite a squirrely / wobbly tire with a unique ride-feel. I suspect that will just take some time to get used to.

@zigro Welcome to eucs! I have an menten 4 that I regularly ride. As OFRs mentioned lower your tire pressure. I think mine is around 30. That’s just my preference, but it will help with squirrliness. That being said this wheel is extremely dexterous and takes little effort to maneuver it. Get more riding time in on it and the wobbles will go away. Learn to carve. If you have room where you’re riding you can start carving to help stop any wobbles. Plus it’s fun as hell on that wheel. While @Cerbera is correct about needing pads on this wheel I have some on mine and I love it. You do have to be careful not to over torque your wheel though. I’ve had too many close calls with being bounced off of my pedals while riding to go padless anymore. You can also jump this little wheel with them on.

No, I was suggesting the opposite of that; that pads are not necessary on such a small, torquey wheel. But, not owning one myself, I happily defer to owners' actual experience, so will have to revise that advice accordingly ! :) I remain convinced we don't need them to impart more power / authority to the wheel, but I hadn't considered that they might help more with stability and jumping etc

🤣 I actually knew what you meant! It was my garbled reply that was the issue.
I like Kai pads on mine mostly to keep me planted on the pedals without it having suspension and hopping over obstacles. definitely not needed in the torque department……

Cool thanks for the comments. It sounds funny, or maybe I just don’t have enough EUC experience, but I experienced less wobbles when I aired it up from 30 to 44. I guess I’ll have to play more with tire pressures.

I’m thinking about trying to make it a few inches taller with yoga blocks when I make pads. I think having more leg contact will make it more stable??

Stability and mten4 are two words that don’t go together. Also the words unicycle and stability.

Also stability and oldness. And even worse oldness and unicycle. 

But that doesn't stop oldies feeling alive. :efee6b18f3:

The mten4 is a wobbly wheel by nature, but you should be able to ride its full power without any wobbles with enough skill. 44 psi is too high. I ride mine 30-35psi. I do have pads on my mten4 but I never use the front ones. I only use the rear ones to brake and I have toe pieces to keep my feet from falling off when hitting bumps

I bought my wife an A2 recently and new to EUCs, had the tire pressure at 30psi when I started.  I am 220lbs and my wife is 98lbs.  I lowered the PSI to 20psi and it feels so much better.  Not as bumpy and the wobbles are much less.  Not sure if it's a proven fact but I have noticed I have much more control when my feet are as far out on the pedals and not close to the body.  I started getting wobbles when my heels were too close to the body.  Was cruising along at about 16mph and it started doing the funky chicken under me.  Rode it out (No idea how I accomplished it as it was pretty out of control) and learned not to lean too much into it compared to my other wheels.  Love it though and may pick up another to have fun with during lunch at work and around the house.

The lower you go, I would be more worried of the tire bead unseating mid ride. 20 is probably the lowest I would be willing to go, but that sketches me out. I forget what the A2 tire is rated for

I would probably move it up to 25psi since it's my wife riding it.  No crazy jumping or anything.  Just cruising the streets looking for trouble to get into :lol:  I've gotten numerous looks and questions from my neighborhood about it.  Trying to start and EUC gang in my neighborhood lol.

I've only got an Mten3 but the trick is to have your shoes tight up against the body. The small diameter is otherwise too twitchy.

If your ankles hurt then put a bit of padding there. 

Tire pressure has changed the riding characteristics on all my wheels except the Mten3. It seems that whatever pressure I ride it remains squirrely. Even on a flat tire. So I can't recommend trying to adjust the tire pressure alone to solve your problem.

Any updates with the wobbles?

Just got mine for 3 days, and once I am around 8-9 mph this thing start shaking like a dancer, is really baffling. iDK what to do so I have to stop.

I though the wobbles would come at higher speed.

It’s practice. Spend time on it, do lots of turns. It’s such a light twitchy wheel that any small movements will affect it. That being said those movements are very easy to compensate for. This wheel is constantly needing subtle inputs from you to keep things steady. I ride mine regularly at 25-35km without any issues. It just takes getting used to, especially compared to larger wheels.

What is your weight and what PSI pressure you both are ridding?

Those things also make quite a big difference, especially when just starting out..

 

Higher psi one is riding - the more it feels like you are riding on knife edge - more wobbles..

I improved a lot already, now I  only experience wobbles going down hill, sometimes I have the feeling that is my feet that start shaking then creates the wobbles.

I still need to be hyper focus though, im guessing a couple weeks more to ride it a little normal. Right now anyone who see me on, would know that I am a Rocky.

Thank you.

The trick is to be relaxed. If the wheel wobbles, let it buckle under you and don't try to grip it, but let it do its thing until it gets over it. You get wobbles when your stance is not relaxed, e.g. when going down hills and you're tense, because then you more-than-usual "grip" the wheel in one way or another (meaning your feet prevent it wrong wobbling freely until it calms down on its own, and then the wheel wobbling starts making you lose balance).

What also helps against wobbles is going into some other somewhat powerful movement (like going into a turn or some other one-sided move like weaving), because that just gives the wobbling wheel some other input that makes it do something else and therefore stop wobbling.

All you need is experience (because then you will be more relaxed in all kinds of situations) and this will go away, but it helps to consciously go for being relaxed (e.g. good and comfortable foot positioning on the pedals!!) and to know what to do when some wobbles start. Think of the wheel as a bucking bull that you need to calm down before it throws you off. Basically, your job as a rider is dampen the wheel's wobbling - it always does that, and how far it gets is up to you. Will it eventually throw you off, or will you get it to knock it off and be the boss? That's how I think about that:D

Totally agree, I was feeling super confident didn't realize my tire was losing air, till got flat.

Once I inflated again to 40 some I couldn't control it, confident to trash again. I lowered pressure then , idk how much but feels good, I may need 

A calibrator and slime to keep it like that.

Each their own. I weight 280lbs and ride my wheel around 35psi. At start when i was learning i was riding at 28psi. Because anything over 30psi would give me mayor wobbles over 25kph speeds. At 28psi i din't have any wobbles at all.

Now i can ride any psi without any problems.
