  1. Since the beginning I have been pondering on how to weight balance my EUC to minimize the wobble created by an unbalanced wheel. "Beginner legs" or tense legs do ofcourse cause wobble, but I don't want the wheel to add to it. This has also been asked a few times here, and today I've finally found a decent, reproducible way to do this! You need a kitchen scale with a precision of 1 gram, and ofcourse the weights. I bought the weights from a local store that sells parts and accessories to cars and motorcycles, among everything else. First determine which side to use for the weights: 1. Put a strip of masking tape to the tyre, from the air valve across to the other side. 2. Set up a (phone) camera to record video, as in the pic above. Slow motion video works best. 3. Sit on a chair and start the EUC. 4. Use both hands on the handle to rise the EUC from the ground. Find the balance so that you can keep the tire still. 5. Very slowly start to accelerate forward. When you feel the wobble at it's strongest, hold on to that speed for 5 seconds or so. 6. Stop and watch the video. You should see the wobble, usually both up-down and sideways. If the EUC turns right when at it's low position, attach the weights to the right side. If left, attach to the left. Now locate the spots for the weights. A kitchen scale rarely measures past 5 kg or so, so you need to distribute the weight of the wheel. Most rigid half a meter long things will do. I used a leftover piece of an in house floor board. Make sure none of the parts of the system touches anything soft, as this will mess the measurements. 1. Place the EUC on it's side on the very end of the board. Face the handle to the free end of the board. 2. Place the kitchen scale under the other end of the board. Place a small rigid box (or any suitable thing) between the scale and the board. 3. If the weight on the scale is out of range, move the EUC even further to the end of the board. 4. Turn the wheel by hand to locate the masking tape, and write down the number on the scale. 5. Very carefully rotate the wheel forward to the next motor bolt. This is usually 1/12th of a full cycle. Write down the number on the scale, and repeat until you are back at the masking tape. 6. Locate the position where the weight on the scale is at it's high point, and place the weight to the wheel. Repeat part 5 until the weight difference is under 5 grams or so. Now turn on and lift up the EUC again. If there is still a notable a side-to-side wobble, shoot another video. Locate the spot that is facing forward when the wheel turns to the side the weights are on. Move the closest weight to the other side, and check if the wobble went away. With the above process I was able to minimize the wobble to a tiny shake at full speed.
  2. Before I take this thing apart, I'm wondering if you guys can give me some insight on what this "wobble" or "play" is so that I know what to watch out for and what I'm getting into. How dangerous is this? I've attached a video, but I'm not sure if it will display properly. Gotway ACM 16 Wobble Play VLC Android SD High.mp4
  3. I love my new 84v ACM but I think the tire or wheel may be imbalanced and i'm not sure if this is a problem or if it can be fixed. When i lift the wheel off the ground and let it spin, it has a slight wobble or shimmy that natrally gets worse with increased speed. similar to how a washing machine wobbles on its spin cycle if the clothes are off balance. The wobble begins to be noticeable around 10-20 km/h Its not a side-to-side wobble, which is good. in other words the vibration is mostly up-down. the tire is tracking straight to a reasonable precision. I don't notice the wobble when i'm riding it. As long as my weight is evenly distributed, it's a smooth ride even at 35km/h, which is as fast as i've dared to ride so far. Does anyone else have this kind of wobble and is there any way to fix it? I don't even know if the imbalance is in the tire or in the wheel itself. I don't know if this is affecting my ride experience or if i should be concerned about it.
  4. Newbie to EUCs, just got mine a few weeks ago. I'm wondering if this is normal, or should I demand a new one, or perhaps try to fix it. When I lift the EUC off ground, it spins to max speed and soon turns off. While the wheel is slowing down, the whole device shakes quite strongly. Looking at the edge of the rim it goes up and down in relation to the EUC shell, as if the wheel axle was slightly off-center. I'm a beginner and my riding is not smooth enough for me to notice it while riding. Here's a video to demonstrate the issue. Is this normal?
  5. MSuper V2 Wobble / Shaking

    Hello everyone, Has anyone experienced the EUC wobble / shaking captured in the video below? Is this a tilt back mechanism or some kind of mechanical issue that needs to be fixed? Thank you in advance for your help!!
