Electric Unicycle Terminology

Recommended Posts

Thanks so much @esaj !  What would this forum (and the world euc community) do without you?  Pinned (although you could do it yourself too).  :D

Good addition to the eWheel performance post I made about a month back.

I would recommend there be something in the section on 'Out-lean' how the pedal-tilt-back helps with a feedback mechanism that prevents riders from going beyond the max speed capabilities of their eWheel. In my opinion, this is really important topic that, especially newbies, should be aware of.

Good point, I also had forgotten to add tilt-back in terms altogether... added tilt-back & overspeeding, and mentioned tilt-back in out-lean.

Nice post. That helped me get up to speed as I wait for the delivery of my first EUC/Gyro-wheel.

@esaj would you identify the mosfets that need to be shunted to prevent BMS shut-off please in the photo below!?

The factory says it will replace my generic's PCB to satisfy their warranty obligations!! - I'm not holding my breath - they have been evasive and unhelpful so far.

Even if I stuff up the EUC is unusable now anyway!

I'm expecting a N1E+ any day now.

Please correct the spelling 'tire' to 'tyre'. Also, an euc is not a bike, why using pedals? You're not pedalling at all. Footrest or similar would be more appropriative. The rest is perfect! Thank you very much @esaj! :)

There is a saying "Put the pedal to the metal". :D

@esaj  Thanks for the reference - on the BMS modification - hopefully I can identify the relevant connections!

Thank you esaj to put them together!

A suggestion about Hall sensor.

The new generation control board use Hall sensors to detect motor current. May be use Hall position sensor and Hall current sensor to distinguish them.

True that, I'll try to get around to update the list a bit...

Hi there,

 

Can someone show a video of power braking? 

 

I've tried but only seem to out lean and incur shut down. 

 

If be keen to see the technique of this. 

Thanks!

Have you searched Youtube?  That is an interesting question, I am about to search Youtube but even if I find one I don't know how to post it.

You can't really prevent this by a specific technique apart from braking more gently. Generally, keep the upper body vertically upright and the knees flexible. To brake rather don't lean back, but push the wheel with your legs in front of you.

the content describe detail function of every part of EUC. Especially, the end of  this content tell riders why your E-wheel shut down and you falled.

very very useful topic

I was looking at some of the products on the IPS website, and I was wondering what "IP Level" means.

Is that term specific to that manufacturer, or is that an industry-wide term?

Ok, this post was near to 2 years old. Updated some stuff that has changed since:
-Only mentioned 16-cell series as common battery configuration, nowadays 20S is also very (if not even more) common
-Stroke out the warnings about BMS cut-outs, these seem to be a thing of the past, now we deal with melting wires, broken gyros and whatnot... :rolleyes:
-Ninebot was the only one offering "over-the-air" -firmware upgrades at the time, now most mainstream manufacturers have those
-Hall-sensor based current measurement seems to be more common place than plain current sensing resistors nowadays
-Suggestion of minimum of 500W+ motor for heavy riders updated to 800W+
-Mention that modern wheels usually have separate inner- and outer-shells
-Firmware-based power cut on overspeed seems to be a thing of the past, overleans/overpowering still exists, as well as burning boards
-Removed the link to BMS shunting, anyone buying something newer than late 2015/early 2016 wheels shouldn't need to do this anymore? Do note me if that's not the case
-Added "MOSFET" in technical terms, as it comes up every so often
-Redefined "overspeed", somewhat 

-Clarifications of some terms, other minor fixes

Anyone know of other terms that should be added?
