  1. There must have been Freud in play hmm, I let strangers try all the time. I do say no sometimes, but more often I say yes. And I probably would do it even if I had paid 1700 bucks. Didn't you buy yours used?
  2. IIRC, there are inconclusive reports on whether Li-Ion batteries may gain capacity within the first few charge cycles. I wouldn't bet either way. I can squeeze a little over 400Wh out of the battery (measured with the charge doctor, CD), and see around or below 11Wh/km consumption with 80kg payload if I take it easy. With lots of acceleration and deceleration it becomes typically rather 17Wh/km. From these numbers I would have no way to conclude that you have a defective battery.
  3. It seems you make an equivocation of the word problem using it with two different meanings in the last sentence. The first refers to the challenge ("problem") of engineering a reliable product and the second to failures ("problems") we have observed in existing products. These are different things. We can observe many failures of a product which poses very little engineering challenge, for example due to a mistaken specification. You really disagree that it is a much much much simpler to replace a weak axles with a more sturdy one than to have an entirely new motor design with a much larger hole in the middle? Strange.
  4. There is no reason that an axle cannot be larger than 18mm and there is also no good reason that an 18mm must break, other than lazy or careless engineering, IMHO. I believe the design with the hole in the middle makes the choice of bearings more difficult, at least in practice. Bearings are the only part of an EUC which needs to move (smoothly) under full weight load. With the hole in the middle, the bearing becomes much larger and (much?) heavier and the bearing seal needs to cover a much larger area with higher speeds against each other. This engineering problem might have a reliable solution, but it will not come from engineers who cannot even design a reliable axle.
  5. I guess so, but it makes all the difference whether "enough times" means 1000 or hundred million. We can build metal bridges which live for decades and withstand millions of vehicles traveling over them. I don't think that the axle of an EUC needs ever to be a point of failure. If it is, it was IMHO just lazy or careless engineering.
  6. For my use case, I wouldn't actually know any superior alternative on the market, so at this very point in time I would buy it again immediately. Riding control is stiff and excellent, it's comparatively light and thin. If I had the choice, I wouldn't even know whether I wanted rather be able to fit a 16x2.5 tire (instead of 16x2.125) or the wobble go away, if I would have to chose between these two.
  7. This is indeed key. Another way to put it: I let the wheel climb on its own with as little as possible rider weight on it. Similarly for down curbs but "in opposite order": if time allows I bend the knees in advance, ideally such my own CoG practically only changes horizontally while going down the curb (knees remain soft and never fully straighten). This, I believe, removes a lot of strain from the axle, probably at least halving the additional stress.
  8. you may want to try google with "site:http://forum.electricunicycle.org" as additional search phrase.
  9. So what happened?
  10. Depends on the step size. Above 10cm I step off, depending on the situation possibly also for smaller curbs as well. Only for fun and only a few steps down. no. Please, do not speed up, don't, ever. Yes, I slow down, of course. When I fail I just step off. Has worked so far, but the failure rate is getting close to zero. What can I say, I do it, so why should I recommend against it? I am happy with what I do. Good one, should have been the first question
  11. Do you have personal experience with a valve actually failing due to dirt? I have been riding motor bikes thousands of km through mud and through deserts, but I cannot remember to have assigned any importance to the valve cap. I also cannot remember any of my companions caring to have a cap on their valve. As always, it could be just my memory that doesn't serve well EDIT: as there seems, on the other hand, to be no good reason to dump the cap, I do have a cap most of the time.
  12. Fatigue...I don't know, I have never had a "death wobble", but the wobbles on my V8 just don't go away, even after 2000km. The good news is that they lost the ability to scare me. I even start to enjoy them from time to time.
  13. This is how you can mount them on the wheel, inside out In fact, that is what I did after a week or so: I mounted them on the wheel (using the same strips) to be in the same position where they were when attached to my legs (while standing on the wheel). It worked very well with the model I used and I kept it for several months. It probably would not work as well with the above shown model.
  14. Hard soccer shin guards (turned to the inside) worked perfectly fine for me. I wouldn't have been able to learn riding without, just too much pain and too low pain tolerance.
  15. Just taking the consequences of the value of choice to an extreme example, but yeah, one might call it trolling. Preventive safety measure against human errors, negligences or crimes are in essence removing possible choices. Choice has a very positive connotation in the American language, but in reality it is a very mixed bag.
