Hey y'all! I've spent a year riding EUCs and ripping through upgrades (IPS i6, InMotion V8, KS18L w/Pedal Upgrade, MSX100V 1.23kWh, and now a MSX100V 1.85kWh coming in the mail). I started off thinking "bleh, I'm not a speed demon like those crazies riding GotWays" so I started off small, but I found that I really love the speed and safety of having more power and keeping up with cars at 70km/h. The big tires also lessen my fear of potholes and other road surface aberrations. Alongside my other hobbies (skydiving and alpine climbing), EUC riding is up there on my favorites list. The EUC is also a convenient tool for short errands, last-mile transport, and walking the dog. I truly believe it's the future of urban transport. So having dropped another $2k on this hobby, I'm idly pondering the future directions that EUCs will take and how they can get better. Could we get together a wish list of near-term and long-term improvements that we'd like to see on the EUCs of the future? Here's my list. Short-term: Kuji Pads standard. Besides enabling tricks like jumping up curbs, Kuji Pads are a safety feature, helping reduce foot slip when traveling over irregular terrain. Long footpedals standard. To extract the most performance (and safety) out of your EUC, the pedals need to be as long as your foot. This allows your center of gravity to shift as far forward or backward as possible, allowing the greatest control input for rapid acceleration and deceleration. It also allows you to climb and descend steeper hills. With the upgraded pedals on the KS18L, I've climbed the steepest hills in San Francisco with no complaint. The same cannot be said for the standard short pedals on the MSX. Footpedal grind guards. Pedal scrape is no joke, especially if your pedal hits a bump in the road. Danger arises from the potential for the pedal to get "stuck," causing a sudden torque and launching you off the EUC. If the pedals had low-friction grind guards on their leading edge (made of acetal or UHMWPE, for example), this would lessen the odds of getting stuck. Of course, they would be consumables. Dihedral footpedals standard. The angled dihedral footpedals of the MSX seem weird at first, but they really secure your foot against the EUC—a huge benefit for reducing foot slip when hitting unexpected bumps, or when riding one-footed. Especially if you must make frequent stops, such as when walking the dog, this latter point is important for lessening foot fatigue. They also lessen the odds of pedal scrape on sharp turns. Long-term: Higher speed. Keeping up with cars is lots of fun, but also important for safety (drivers DGAF). I'd like to see future EUCs with a top speed of 80 or 90km/h. Bigger battery. Since drag force rises quadratically with speed, you need a bigger battery to go long distances if you're going fast. I'd like future EUCs with 3kWh or more. Shock absorbers. My knees are fine, but using them to dampen the resonant tank formed by the tire's spring force and the EUC's mass can be a challenge—as a human, my response time isn't fast enough to dampen it well; I need to anticipate and prepare for the shock. Especially on poorly maintained roads, it's difficult to keep up with the repetitive and unpredictable force impulses when traveling at speed, causing anxiety about foot slip when traveling on unknown paths at night. It would be preferred if shock absorbers (important: with dampeners) were integrated into the EUC structure, especially if the battery was kept unsprung. I imagine this would result in a supremely buttery ride. Belt-drive. This one's debatable, because it introduces another point of failure into the drivetrain, but... The power you can get out of a motor is proportional to the product of its size (namely, its volume) and how fast you spin it. With direct drive, where the motor is integrated into the wheel structure, you aren't spinning the motor very fast so its power density is remarkably low. As a result, for a given power level the motor must be really big—and neodymium and copper ain't cheap. If you added gearing or a belt drive, then the motor could spin faster than the wheel and be much smaller—like a hobby motor. This would substantially reduce the cost and weight of EUCs. Additionally, the sprung mass could be reduced and it would be easier to carry around. I take pause because it adds another point of failure if the belt breaks. While a drivetrain failure on a motorcycle might cause a fall, a drivetrain failure on an EUC will cause a fall. Maybe some belt-drive experts can chime in. Foot attachment. Having dihedral pedals and Kuji pads helps to reduce foot slip, but nothing can beat a true attachment. It needn't take much force, since it would only need to prevent your feet from slipping off while catching air, so "clip-in" pedals like bicycles or skis would be unnecessary. Preferably something that can be detached easily when you need to step or jump off. My thought at the moment is to place a magnet on the pedal or the side of the EUC, and to have a small steel plate that pins to the bottom or side your shoe that is attracted by the magnet. Articulating seats. Control of acceleration on the EUC arises from your ability to translate your center of gravity longitudinally, fore or aft of the tire's point of contact. Your ankles' articulation permits this motion. Fine control of steering is done by twisting your hips (and by extension the EUC) axially against your torso's rotational inertia, and course control by lateral translation of your center of gravity to the left or right of the tire's point of contact. The former is permitted by twisting articulation in your trunk, and the latter by articulation in your ankles and hips. On a seat that is rigidly mounted to the EUC, your ability to perform these translations and rotations is greatly diminished. In this case, you are reliant on the compliance in your butt tissue, which even for those blessed with child-bearing hips is not much. As a result, your control inputs on a seat are severely limited. This endangers you since you cannot steer or decelerate as quickly as may be needed in the event of an emergency. Articulating seats that permit a few centimeters of longitudinal and lateral translation, and several degrees of axial rotation, should greatly improve this situation. Maintenance schedules. As EUCs become faster and more powerful, and as more people ride them, it becomes more critical to keep them well-maintained. Manufacturer-recommended maintenance and inspection intervals may be wise. What's your wishlist? Cheers!
Hello guys.... I am kinda new in EUC community, Ive ridden only V5F and now waiting for my KS18L to come... and I travel a lot, so I started thinking about how to get EUC....bur 1000Wh battery and 22Kg.... So... Is there any small and light unicycle with battery <160Wh and weight <8kg ? I dont care about power of it... Thank you guys, have a great day!
EUCs can be transported with every transport unit: car, train, tram, bus, ship, at the hand,... but not in airplanes since it is "dangerous" even if the probability of exploding is 0,000001%. I asked to certain airplane companies. They did not accept motorised instruments with battery. However the most important thing that you miss when you go somewhere with an airplane is your car, bike or EUC. Holidays would be much cheaper and much efficient if we could take our EUCs with us in the airplane. Would you vote yes if I open a request for change of these regulations worldwide towards IATA, organisation of worldwide airplane companies: I propose to use the site change.org Or do you have other suggestions to change this regulation? However I know a friend who has taken the EUC with him in the cabin. The stewardesses were more busy with being surprised (with a big smile) with this new instrument than thinking about the fact if this instrument is allowed in the airplane or not. I am sure that there is no regulation specific for EUCs but we can vote for the first regulation so that it becomes in our advantage. Besides there is no danger of exploding since you are not charging the EUC. Even if you charge it, the probability is negligible. This voting is necessary to avoid to throw your EUC in the trash to enter the airplane
According to SoloWheel Xtreme printed specs on the pedal, it has a 160Wh battery. That means it is air travel worthy. What are the odds that airport security would prevent me from boarding?! (plane ticket is way cheaper than wheel, I rather miss the flight!) If you have traveled with electric unicycles, please share your experience! I took a picture of the printed data on my SoloWheel Xtreme's pedal:
