Inmotion V8 Acceleration - Accelerating faster


Bigwheel

Recommended Posts

I still consider myself a new EUC rider but I'm finding my v8 doesn't accelerate fast enough. I want ' pedal to the metal ' and to take off quickly but it's not as a fast experience as my electric skateboard. It's almost as if the pedals need to be more sensitive? I thought i'd put this out to the experts here.

 

Is there anything I can adjust in the settings for the pedals?

Is this technique?

I have used darkness bot to unlock the top speed hoping that would help.

I'm not sure what settings are available for the V8 (for the V10F for instance you have "pedal sensitivity" which affects the riding experience). As far as technique goes it's a matter of how hard you lean into it, lean hard enough and you will push the wheel it to it's maximum, but lean too much and you can push it above its limits.. :(  In contrast to a electrical skateboard you only have one wheel, so if you go above the limits you'll not only get "pedal to the metal" but "nose to the pavement" as well. To drive safely with any wheel you should instead try avoid hard accelerations and hard braking, and at the very least know the limits of your wheel with respect to your weight, etc. The V8 isn't the most powerful wheel either, so I'd try to temper my speed hunger if I were you. As @UniVehje said other wheels might give you a snappier response.

First of I don't use iPhone so I have no access to Daknessbot. 

I used Inmotion app in the beginning but had connection issues after updating android to8.1. Now it has been a while since I last used my Inmotion V8 due to a crash. But today I got the needed spare part to fix it, I hope?

I tend to recall a setting for pedal sensitivity. This is one this that can effect what you are asking. The other is learning how far you can lean or as I do now push with my toes or front of my foot. 

You don't want to go too far as this can cause a overlean cut out. You will soon get a feel if this once you practice this. The opposite is the case for breaking. 

Imo it is good to practice this to get a feel of this, and in case of an emergency you know what to do to break or accelerate out of harms way.

The V8 just isn't that powerful with a small(2p) battery (limits the available current) and the comparably weak motor (it wasn't weak when it came out, but nowadays motors on 16 inchers are just stronger). You can't expect too much (same for the speed unlock, that's just a bad idea in my opinion).

What's your weight? Also as said, maybe it's just the pedal hardness setting (though that would show more in how firmly the pedals stay level, and less in how much oomph you feel).

Well I got my Inmotion V8 "fixed" but...?

It doesn't behave as I recall before my crash. First of now I can't connect with neither Inmotion app nor the wheeloc. Both updated to latest version possible. Before I could use manual by mac add as in wheelloc but for some reason this doesn't work anymore.

The second part is more worrying to me. It is tilted back a fair bit. I cannot seem to reset this. I am not sure if this is do to my crash or because I had motor disconnect to change tyre and tube.

It feels like is slowly sliding when riding. It kinda change the balance center (forward/backwards) when driving/riding it. I recall this from before when turning sharply but never in this way.

So @Bigwheel I am afraid I can't assist on this. My concern is if my unit now is faulty due to my crash or maybe prior the crash or this is normal behaviour. I can say for sure my KS18L do not give me that creepy gyro shift feeling.

What do you think @Jens Ronnedal does this sound familiar to you?

As you know I'm an iPhone-user and I don't have any problem with apps. I used the Inmotion-app briefly when I got my V8 but as soon as I found out about Darknessbot it's the only app I mainly use. I only use the Inmotion-app for foot pad tilt adjustment. The 18L and V8 are very different rides. After riding the 18L for just 30 minutes the V8 feels like a kids toy.

But to ride a wheel with the wrong tilt on you food pads really suck. But in the Inmotion app you can set it manually. But the first thing you should do after a big crash/repair is to do a calibration.

There are ppl thinking that the manual foot pad adjustment is the calibration, but as mentioned in this video it's not. But if you're having trouble with the app you should as someone with an iPhone to download the app and you can just use it for a few minutes to do the calibration and adjust the foot pads to you liking. I use a 2% offset, that feels natural to me. But when I got my wheel it was like 4% and it really hurt my calves.

This almost certainly does not help. You really should not unlock the top speed unless you either understand the consequences very well or you are fine with risking your health in a high speed crash. Your hope that this would help to improve the torque at zero speed tells me that the first is not the case.

Ok, that's why i'm here, for some advice.

@Unventor I'm about 150lbs so a light rider.

@Jens Ronnedal  Thanks for that video!

@Bigwheel, this is the short version of torque vs speed: the maximal motor torque is available at zero speed (only) and the available motor torque diminishes linearly with increasing speed down to zero that the maximal nominal motor speed. The available access torque for keeping the wheel balanced diminishes even faster with increasing speed. Yet the demand torque to keep the wheel balanced when going over bumps or potholes is increasing with increasing speed, which is a rather unfortunate marriage. EDIT: being soft and responsive in the knees and bending them immediately on impact is the most important countermeasure, but for me it took lots of practice to adjust my reflexes and I don't think I am fully there yet even after over 500 hours of riding.

Aha! Thanks. That makes sense. I appreciate  the explanation  :)

That said having a momentum helps the wheel to climb a bump/edge/pothole. 

If you go slow the motor have to carry you, if you go fast the motor might not be able to maintain balance. Somewhat inbetween is most likely to be ideal but every situation is different so this is where rider experience and practice and the different roads/terrain experience will help you. It is easy to go fast, and too fast. Imho anyone riding EUC is bound have an accident sooner or later. The speed you have when happens partly determine the outcome.

Trust me, I have had accidents on bicycles and my EUC. Some more painful than others. It is part of living ?
