Nice review and thank you for your insight.

 

I wonder, how would you feel riding an EU in town on the sidewalk or pavement at 30 km/h without any protective gear??

Would you still go at that speed or would you slow down.

Bring a video clip has been taken some time ago. Today, after a period of the same route, Firewheel beeps all the time  :D
 
When I'm on the move in the center. I tried to drive around max 15kmh.
 
So far, I have never been on the move without equipment.
As always when I go to run, I go to the terrain.
When I go to run and when I come home, I can run at the same time in the center of the small circle.
 
I am currently the only city that drives the unicycle.
I draw a lot of attention.
I'm trying to set an example by driving cleanly.

Okay. A little experience with my new Gotway 14" MCM2s 680wh
I got it today, as well as my friends own :)
We were together for the first ride.
We both liked very much.
 
We used the Madden Mode.
Pedals were felt in the legs of a suitable hard.
Just a little bit softer than Gotway 18".
Perhaps the pedals had to be a little larger.
At the same time they would have to lift the top. Now, however, they are not easy to hit the ground. But I think that of all the unicycle in are a little too low. They must not touch the ground up to the flat.
 
Gotway was quick to respond and it was able to make quick turns and changes of direction. Even a relatively hard speed reversing was smooth.
 
Rapidly accelerated. Does not go out under heavy workload. But when the battery is approximately 30% of the left, uphill grade, hard acceleration pedals got to settle down, and it was followed by the collapse.
Maximum speed is not yet tested. It later. According to Bluetooth, maximum speeds of 26kmh.
I think that this speed was a little too small. Driving characteristics were easy enough to greater speed because, it was surprisingly stable ride.
I did not expect that it would have such a nice drive in a longer journey.
 
The engine is very quiet, and the sound just heard even though it was quiet.
Beep of the traffic noise was clearly among the congregation.
 
Wheel is too close to the plastic shells.
Rubber gripped the rocks, and they crowded into the rubber and the shell between the time. It was all the time the sound when hit in plastic.
As soon as the beginning of the run to a hole was left stone.
There was uproar when it hit the frame, and refused to go away. It is still there.
 
4.0 bluetooth application did not work here. We spent the next state of the art.
It works in both 14" and 18".
 
I am pleased.
Annoying that Gotway make a 16 "unicycle.
Hopefully, this will change.

 

Hope you have understood my English :)

Come on  :ph34r:
Now, Gotway 14" MCM2s 680wh the top speed has been tested by running.
Bluetooth speedometer displays of 33 km / h. Since then, pedals start to go down and almost immediately turn the engine off, because the program protects the driver from excessive speed and dangerous situation  :D  Great job.
 
I tested the asphalt, was slightly uphill.
The battery was completely full.
The tire pressure 3.4bar.
 
I tried to quickly accelerates to 33 speed.
I do not have time to react adequately pedal down for landing.
So I fell down. So do not accelerate more rapidly to more than 30-31kmh.
Let's see what seems when I do the battery was a little modding.

Now, when I noticed that the Gotway 14 goes far louder than what the beeps suggests. I removed the speaker completely.
The switch did not bother to install because, speaker, and the wire was so narrow place, it would be to have canceled all out first.
It was difficult to get the plug out. the speaker is on the front of the handle inside the connector and it pretty close to the circuit board.
It should be noted that, in all gluing was used in a proper adhesive mass. And not as usually all the hot glue, which leaves almost immediately terminated.
Eg. Firewheel use hot glue, and all have left off as soon as new.

Hi vee73!

 

It is your fault that I own gotway14 EUC  :)

I saw in january in yle website story of your unicycle hobby.

 

I live in Oulu and here I'am probably the only one who has the EUC.

 

By the way do you have noticed this:

Hope you didn't get hurt.  Did you wear protective gear?  Did you manage to run it off without falling?

When doing a test of lifting up the euc above the ground the motor for both MCM and MCM2S (at 66.2 Volts) shuts down at 40 km/h (according to the gotway app 4.0).  I guess with a person riding on it it the shut down speed goes down a lot.  In your case 33 km/h.  So I guess an "lift test" results should subtract around 7 km/h for real life riding results.  How much do you weigh?

Interestingly at 61.7 volts (3 led lights) they shut at 37 km/h.  So the battery charge level is really important and affect the performance.

Hello
I have been in hiding for some time here.
I went here, 600 km to the south. Because here's forests are still here in the snow and I wanted to test Gotway 14 and 18, as well as Rockwheel, in the woods in summer conditions.
Returning home just now.
 
Rockwheel was a slight disappointment. In managing the forest was more effort than Gotway 14".
Probably due to the clearance of the stroller. It did not go so easily because the roots of the trees, branches, pine cones, tree stumps and all the other resulted in a lot more effort feet.
 
Of course, 18" went really well.
But the biggest surprise was Gotway 14". Pre-I thought that it would not be very good in the forrest. But I choose rather Gotway 14, as the Rockwheel 16.
 
 
We'll be back Gotway 14 speed test ..
I used to, of course, personal protective equipment. I do not hurt.
But I can say that, a lot of happy I fall 40kmh speed than 30kmh.
Since 30 kmh speed asphalt crash is far worse because the speed is not sufficient for that body would go slip.
Hit the ground, but is much more striking.
 
40kmh speed crash is not so painful because the friction is just right that the body begins to slip away, and it will not hurt.
It seems to me that even if I fall like to 60kmh than 30kmh.
I hit the helmet and hand with great force because the slip was not successful. I got hurt, but it went over. Nothing serious.
 
When I test the speed of raising, it will turn off approximately 38kmh.
My weight is 65kg.
 
On my way to Gotway 14 voice gained strength. It's the sound that I think a stone somewhere in between. I no longer believe that it is due.
I have to open and check the size of the device.
Little by little, I think that the sound comes from the engine because there is something out there should not be.
But when I have time I open it.
 
 
kotvei14, hah haa.
It is great that you bought as soon as proper. You made a good choice.
On my way I drove past the Oulu ..
I am aware that these will be legal in our country. That is great.

Hello again.
Gotway 850wh charge takes approximately 8 hours.
 
A few words about my signature.
I try to briefly tell you what I have had a unicycle, and is at the moment.
Crossed out is the new owner.
Smilies tell you what I think of each am.
They may change slightly over time you get to know them better. And the miles will be.
It's what I like most is the top of the list, etc.
These opinions I have formed only in my own experience.

Gotway 18" pedals.
The big problem of the foot from slipping did not have, but sometimes can be very hard to slip jumps and vibrations.
So try this.
M4x6mm set screw, or whatever it is.
They do not wear out easily and are not too sharp. Also, their height is easy to adjust. I put the soft fixing glue.

"Why the machine can not only stop the escalation? Why should one be total shutdown?"

 

This makes some sense to me.  If you think about, when you lean forward the device has to either save you from falling by accelerating, or let you fall.  So if you keep asking for more speed it has to give it to you until it simply can't anymore.   The best it can do is warn via beeping/wabbling/tilting, that you are approaching its limit.

 

In summary: The device cannot slow you down, only you can slow you down.  Does that make any sense?

Quite right Sam. It's a feedback system but you need to take notice for it to work.

No. This is not my opinion, make any sense. Nowhere else in the electric motor does not turn off maximum speed. It just does not rotate any more.
I can not think in any other way  :)

Gotway 14 shells into my use, taking into account too low.
For example, skateboard ramps driving is not possible without this measure. I'm not sure whether this is sufficient not yet, but tried first.
I do not want to take any too much, because the water easily begin to fly back.
This notice how very close to the ring rotates inside the shell.
Screw the case so close, so that no dirt can not get out.
And dirt has accumulated a lot.
 
On the other hand, the shells will take the knocks better when the tire is to take some of the impact.
 
But the studded tire is quite useless to dream.

Say the motor is at maximum sustained power output (500W for example) and the rider leans forward to get more speed out of it. There are two ways that situation could go: 1) Request for more speed denied, motor stays at the same speed and the rider is still leaning forward. The rider will immediately either lean back or if they don't realise they're at the limit, fall on their face at maximum speed and get run over by the wheel. That option is pretty bad. Option 2) We throw some more power into the motor, exceeding its maximum capacity, in the hope that the request for more power is only temporary like we're climbing a small hill and will soon reach the peak. The motor will overheat if kept in this state for long periods and die, following which the rider will fall on their face and get run over by the wheel.

Either way the problem is you're asking more from the motor than it can possibly provide, however if you immediately deny requests for more power/speed then you will cause the rider to fall on their face more quickly and more often (hit a small dip in the road? That's a face-plant) than if you assume the rider knows best and won't try to draw too much for too long.

Take for example an electric bike.
It gives a maximum speed does not turn off.
But the upgrade with the speed slows down because the motor to be giving more. It is good. It would be good to also unicycle.
Greater chance of capsizing if the speed is reduced, as it turns off completely.
An alternative to the pedals could go down to the front, but not very aggressively. When driving becomes impossible without the fall.

An electric bike is only using power to drive you. When there is no more power it just stays at that maximum speed for the conditions at that time.

A euc needs some reserve so that when you hit a dip in the road it can catch up and keep you balanced. It's only when you ignore the warning and use some of this necessary reserve that the odd dip or bump will exceed the capabilities of the motor.

I see. But the program could be such that it will not accelerate any more than can be, and yet it keeps you afloat.
Thus, the speed is limited, and yet there is the capacity of which can keep afloat.
This extra capacity would be just the program for its own use and can not control the pedals.

I'm pretty sure that is what is already happening when you are travelling at the top speed ignoring all the warning beeps. It's only when the slightest bit of extra stress is put on the wheel by a dip, bump or extra lean that it gives up.

So, we're back at the beginning :)
Why speed is not limited? And filed in the program reserved for use.
This would be easy to implement.
When driving you know that the machine can not go faster than, for example 15kmh. If you try to accelerate .. speed does not increase. Only use the program, the extra capacity to keep you afloat if the road is throws.

The only exterior input the wheel gets is you or a lump throwing it forwards or back, it then compensates by accelerating and putting you back on balance.

How could a simple machine be expected to know the difference between a lump or bump in the road and you leaning further forward on purpose.

Most of the early eucs had tilt back which takes still more power and therefore must be implemented relatively early limiting top speeds to a very pedestrian pace. Lots of people asked for no tilt back and top speeds went up because of it but unless you want to crash you do have to take notice of the warnings when you approach the upper limits.

I do not think that it would be difficult to make a more reasonable speed limiter.
Furthermore, I would argue that the failure rate of the maximum speed which would in all circumstances, a better solution than the current total shutdown. Anything else would be a safer :)
To make even a unicycle top speed would be so high that no one dare to run until the end  :lol:

Yes I agree. In a perfect world where limitless power was available from a ridiculously small electric motor it would be great. :)

What we have at the moment is wheels leaving all the smart decisions like speed up to the rider, like a kit car with a lot of engine power and no traction control etc, cheap and great fun but very easy to have an accident with unless you're careful. What we had before were poorly implemented safety features that erred on the side of caution, low speed limits, push back, etc. 

What you want if I'm interpreting this correctly is a wheel with well designed and reliable safety features, if I can stretch the metaphor, you want a modern Mercedes wheel, we currently have 80s Ferraris wheels, and previously we had... I don't know, something awful from the 50s. We'll get there dude, but the best thing you can do to help at the moment is figure out how the electronics work and add improvements. I'd like to add a temperature gauge on a Firewheel for instance so we have a better idea of when the motor will cut out, if it's the same motor as the ninebot then it probably has a sensor built in already.

 

Remember that it's the Chinese companies that produced the poorly implemented safety features in the first place, gotta be careful asking them for anything else, it's almost better to design it in the western world and then have China copy it.
