Can you use “muscle” to accelerate an EUC?

@Darrell Wesh Nice vid! Exactly how I would imagine a sprinter would make a video about getting the fastest dead start on EUC LOL :lol:

Since you're going for maximum push here, you should try to cocking the wheel slightly sideways, wheel leaning slightly down like it's gonna fall forward, so you can use the friction of the sideway facing tire to get push off of as well with your pedal mounted foot (I sometimes freemount this way).

With this, I wonder if you could even just go into semi sprinter's crouch with your lagging foot-side arm mounted to the ground, pedal-side arm leaning off the wheel body.

On the Monster, you could perhaps even have both arms leaning on the front nose, to give extra lean force to the gyroscope input, ala how seated accelerations on that wheel are always faster than standing.

On the Monster

The wear pattern on the right pedal of my Monster, after a few thousand miles of riding,

Right pedal:

shows that I use the balls of my feet to control the EUC in all aspects of riding.

Loss of grip between the shoe and the pedal has not noticible , despite the wear, but my riding style tends to be conservative on generally smooth surfaces. 

Closer inspection of the pedal in the photo shows that the area is where the rubber of the sole of the shoe has deposited between the abrasive contact points on the pedal. The silver color is more a light reflectance when in reality the area is dark black.

 

There is also a small spot under the left heel but not under the right heel.

The installed pedals are the same age. The right pedal broke awhile ago and both pedals were replaced.

 

Left pedal:

Here is a picture of the left pedal , removed (and replaced) following the breakage of the right pedal.

It shows the same wear marks under the ball of the foot and slightly under the heel as the installed L pedal.

As in having both hands on the front of the monster pushing down? Wouldn’t that be dangerous from a safety perspective

The S principle about straight line stability “doesn’t align” with this notion. Excuse the pun lol.

 Especially when you have smaller width wheels that aren’t as easy to keep in a straight line. Just like in any 3 pt start or block start, you want to start already aligned so it’s that much easier to move down the terrain in a straight line. One of the reasons I was able to so easily beat the MCM5 was that it was difficult to both start aggressively and track straight.

🤷‍♂️ I do this mounting to seated riding al the time.

I suspect then that we don't really ride the same way then, as I forgo riding in a straight line for increased gravity-assisted acceleration push.

Yes you would need that assistance but if you followed all the steps in cohesion you would not need to start “sideways”. 
 

By throwing the wheel around side to side, or your coined “pumping”, you can obviously crank it further then a static lean due to momentum shifts. 
 

However, your technique is best used for when you’re already on the wheel and rolling. My method obviously can only work from a dead stop. Once you commit to it and are in that accelerative posture, changing up to pumping would only slow the overall acceleration down.

It would be interesting to see a race between the same wheel and you using your technique from a rolling start vs someone who just leans forward.

It subjectively feels faster to pump, it’s what I use instinctively when trying to accelerate.
 

BUT! It’s also what football players use instinctively when trying to accelerate. What I mean by that is football players are notorious for side to side motion in order to accelerate, and all the track gurus know side to side is wasting time and only looks and feels faster. A straight line is always the fastest route, and I was trained to accelerate as straight as possible, arm movements, leg movements, everything going forward.
 

So part of me wants to say that remaining static in a forward lean only feels slower because you aren’t doing as much work as pumping.

The problem is that technique would only work on certain wheels and wouldn’t be universal. You can’t do that on the nikola... it’s rounded!

I get what you're saying, but you can't completely compare apples to apples, because this is a gyroscopic device we're talking about, not plain running and body physics alone. 

What I've referred to in the past as "pumping", is about trying to get stronger acceleration down force, as opposed to straight and press, which is more about muscle, as the force dies down when you're at the strongest.The alternation is about trying to make a stronger overall sum acceleration force by maximizing the initial downstrokes of the gravity falls, and switching feet when the tail end dies, which is always the weakest force for either method, much like swimmers won't just stroke one arm and hold it (yes, I know, it's not apples to apples comparison).

It would be interesting to see which is fastest in a true test, yes. What was slightly missing in your vid is 2 Darrell Walsh's with same technique on different wheels, unfortunately. Maybe this might be better in solo time trials?

Yes, this is true. You would need a good height EUC with preferably a flat surface, ala seat. But when you Do have it, why not use it?
