If you are a beginner about to train on the Step-n-Roll, you will want to wear protection, not only from falls, but from the unicycle itself. Its sharp edges and hard surfaces will abrade your skin. Experienced riders, who aren't gripping the sides of the housing in a desperate effort to stay balanced, will not likely experience its ergonomic shortcomings. Update 170524: With less than 10 minutes total on the pedals, the last time I mounted the unit and attempted forward navigation, the machine pitched me forward violently. Every time I have turned it on since then, the motor jerks to full speed, the emergency stop is activated, the motor stops, and the beep turns on. On opening the controller panel, I found a loose connection in the yellow wire that I assume comes from the wheel position encoder. I pushed it back in, made sure all the connections are tight, and powered up again. BAM! Same thing. Needless to say, I'm frustrated. I think the most likely fault is in the wheel position encoding or the gyroscope. I guess that if a traction MOSFET went bad, the wheel would probably stutter rather than accelerate to full speed. Thoughts?
Jonathan Tolhurst posted a topic in General DiscussionLearning to do tricks consistently on an electric unicycle requires learning technique, (lots of) practice/repetition, understanding the parameters under which your wheel operates and recognising (and attempting to control, or embrace) any variable(s). Controlling the Variables A variable is an element, feature, or factor that is liable to vary or change. If you are trying to learn to do a trick consistently then it’s a very good idea to have a think about what elements, features or factors could vary, and how these may be controlled. Some variables are more practical to control than others. I have listed some of the most important ones below, please feel free to add any I have missed. Environmental Variables Surfaces Different types of surface will all provide a very different environment for practising and performing tricks. A lot of flat surfaces are not actually flat. The most consistently flat and uniform outdoor surface that I have found are flat areas in professionally built Skateparks. Surface moisture reduces the amount of friction between the wheel and the surface which greatly affects turning and spinning – this can sometimes be used to your advantage. (This variable is best controlled by practising on the same high quality surface). Think Friction, Hardness, smoothness, bounce, incline, moisture, temperature Example surfaces which may all provide a very different riding experience: Concrete Wooden stage Dry Tarmac Wet Tarmac Paving Slabs Brick Marble Grass Gravel Dirt Temperature Different temperatures will have an effect on the riding surface, the tire, the motor, the control board, the battery and the rider. If you are practising in the middle of the day during summer then the wheel is likely to get hot much quicker. (This variable would be best controlled by practising indoors in a temperature controlled environment). Distractions Distractions can impact on practice sessions, obvious examples include: Noise Traffic Spectators other Riders Animals/Pets Electric Unicycle Variables Model Some electric unicycle models seem more suited to tricks than others. It may not be possible to perform some tricks on all models. You may have to adapt your technique depending on differences between models. Variation between wheels may include Wheel size Weight Centre of gravity (this can be greatly affected by where the battery is situated) Pedal Size Pedal Height Pedal Angle Pedal Grip Firmware Changing the firmware that runs on your wheel’s control board may change the whole feeling of the wheel. (This variable can be best controlled by not changing the firmware version). Riding Mode Many wheels have different riding modes which change the responsiveness of the wheel (E.g. hard/soft). (This variable can be best controlled by sticking to the same riding mode). Tire Type The tread and compound on a tire affects the huge difference on ride. (This variable can be best controlled by monitoring the tire tread and replacing with the same tire as soon as adverse wear is identified). Tire Pressure Changing the tire pressure makes a big difference. A higher pressure will result in a faster and more responsive wheel (but more difficult to control). (This variable can be best controlled by fixing the tire pressure as a parameter and regularly measuring/adjusting the tire pressure before a practice session). Battery Charge EUCs can respond markedly differently at different states of charge. (This variable can be best controlled by fully charging your wheel before each practice session). Accessories Attaching accessories to the wheel can impact on how the wheel behaves – these can alter the centre of gravity or restrict entry/exit to/from the wheel. (This variable can be best controlled by removing all accessories from the wheel or having the same accessories attached to the wheel when attempting to perform tricks). Personal Variables Weight Rider weight could be a source of variation. (This variable can be best controlled by monitoring your weight and adjusting your diet accordingly). Fitness (This variable can be best controlled by adhering to a regular fitness regime). Footwear Wearing different footwear can affect your riding performance. Variables include: Grip Sole thickness (this affects your ability to feel the foot plates) Padding & Support Tightness (This variable can be best controlled by wearing the same pair of shoes when performing tricks). Clothing Clothing can be a source of variation. Some clothes can restrict movement and even affect the weight or the centre of gravity of the system. If you are practising for a show it may be sensible to practice in the costume that you are going to wear for the show.(This variable can be best controlled by wearing similar fitting clothing when practising). Safety Equipment Safety equipment can affect your movement and centre of gravity. (This variable can be best controlled by wearing the same safety equipment each session).
vladmarks posted a topic in General DiscussionHey euc lovers! I know there are lots of you who started riding very basic default models purchased off alibaba, ebay and other retailers. These tend to have sharp top corners and hurt your calves more than some of the newer models. Have any of you used/still use particular protection gear for calves to make the learning a bit easier and prevent bruising? We've recently ordered several boxes of branded custom equipment that has extra silicon inserts on the inner sides. The main reason I'm asking is to gather feedback and provide our future customers with some insight about these kits. So far, our tests during the academies show that wearing a set reduces your leg fatigue during the training. However, in order to make a fair test we'd have to set two similar individuals with almost identical physique, which wasn't possible so far. I'd love to hear your thoughts on this: maybe you used some kind of alternative to guard your shins during the training? Just like my technique of rolling up the sweatpants so that only the softest spot interacts with the EUC
So as to not hijack anyone's thread I decided to start my own. The reason for posting this is just to, hopefully, help encourage others that are learning. I've had a couple of times when I was discouraged because I wasn't making any progress. Yesterday before I went out I said that "I'd better make some progress!" and I did. Today I made even more progress. Also, I am going to include some things that I have started doing that I think are helping me. Today was my 9th day of practice. When I go out I can usually only practice for 15-20 minutes. Partially because it's HOT here (around 97 degrees Fahrenheit) and my back usually gets tired from bending over and walking the 9B1 to my launch site (but no more of that). I've been practicing in my kitchen more during the day. I feel it is helping me get better. I also tried mounting unassisted in the kitchen and I think I did pretty good at it. I tried both the hop on and go and the push off (skateboard) methods. I went to a nearby Elementary school parking lot again. My first launch was from my car. All other launches were unassisted. My first unassisted launch was a success as well. And I did good riding (not great, but good). On my very first 'run' I went mostly where I wanted (a first for me. Usually I went 'wherever' and just was able to navigate enough as to not hit anything). I went around the bigger part of the parking lot a few times. It's more like a few small parking lots connected by car paths (see the picture URL below). So that means there are more curbs to miss. I've wanted to find a bigger parking lot but this one is so close to my house and there aren't too many people to see me (like if I went to a store parking lot). I didn't wobble most of the time (like I usually do). It seems like when I wobble it's because my feet are arguing... or getting tired. Sometimes I was even relaxed (hands by my sides). I was able to intentionally squeeze between a curb and a speed bump (about a 3' gap) twice but bailed once. I was successful at speeding up when I needed more speed and slowing down when I thought I was going too fast. I fell twice but they were just because I tripped over the 9B1 after failed unassisted launches. It seems for me that each day my first or second 'run' is the best. I may have some other decent ones but usually not as good as the beginning. I think this means that some muscles are getting tired. They must be muscles that I haven't been using much. During my first run today my turns seemed more natural. Later it wasn't as fluid. It was like I was over-thinking it. The next few days are going to be hotter. I may have to practice in the dark. Here's the school where I practice: https://drive.google.com/file/d/0B7oev598hxU2UEV2emJIX2ZnSlk/view I have been doing many of the things recommended on this forum but here are some things that I have just started doing the last 2 times out that I am contributing to my success. They may not actually be what's helped; maybe I am just getting better... But I think they are helping. I am sure some will say these are wrong but maybe it will help someone. Maybe as I get better I will no longer need to do some of these things. - I deflated my tire some. (I know this one will have to be temporary. I think I will add a little bit of air at a time.) - I have started putting my feet right up against the 9B1 and squeezing to hold it between my legs. At first I was just trying to balance. But I wasn't getting the bruises everyone was talking about. Now I am getting bruises but I think they are just temporary. - Previously I feel I was trying to balance with my hips or with my entire leg (and maybe when my balance was way off this was necessary). But I would usually start going straight for about 6 feet and then veer fairly sharp to the left (my first 'long' run the other day was a series of lefts, wobbly straights and sharp lefts, just enough to dodge curbs and cars). It was a struggle to go right. But while I was practicing in the kitchen today I found that if I pushed with the balls of my right foot I would veer to the right. I think that helped me make the small adjustments that I needed to make when I was out today. Finally I want to say that I think that if I can do this just about anyone can. I've done a lot of things in my life and I was usually a good student. But I am getting old now and most of the things that I have done were when I was a child, teen or young adult. And they were before I acquired some of my injuries and health issues. But I think this practice is going improve the strength and coordination of the muscles needed for balance that I have, apparently, not been needing to use much. One thing I never could do when I was a child was ride a unicycle. I hope this helps someone.
