  1. I agree with you that there are some unknowns and more speed equals more risk. But do you really think an occasional use of an extra few kph over the stock S2 makes so much of a difference as to dramatically increase risk? I am cruising along at about 25-26kph comfortably and when I do push it slightly higher I accelerate very gently and back off the moment the beeps start. Factors such as rider weight, wind and incline should be considered too, as they make a considerable impact to what the wheel can cope with and so max speed, aggressiveness of acceleration and riding style must be adjusted accordingly. My weight is about 68kg and I feel confident in my wheel carrying me at 26kph while having enough reserve torque to keep me up should I hit a bump. We are talking about only a few kph more than the wheel's stock firmware is set to. And we know the Segways are built with safety being high on the priority list and that they are conservative with their speed limits.
  2. What was the ambient temperature you were riding in? EDIT: Never mind, I see you're in LA so it's not a cold weather issue. Where I am it has been sub zero for months and riding in that yields shorter range.
  3. I think a safe way to look at this firmware hack is that it allows us to cruise at around 26kph without tilt-back or beeps. To ride it at 30kph most of the time is too risky for me, personally. We know the S1 (two battery version) and S2 are capable of 26kph as Segway sells the same hardware in Europe with that speed limit, but they restrict it to about 18kph for North Americans. So I see no reason why it is not safe to ride these at around 26kph when the hardware was designed for it, with the luxury of being able to occasionally speed up closer to 30 for overtaking cyclists on the path, provided the battery is above 80% charge just to be a bit more cautious. That's the way I'm approaching this, anyway.
  4. I was able to take my upgraded S1 out for the first test ride on a stretch of road without snow. It's amazing. It goes right up to 30kph and then a very rapid beeping begins. I didn't feel any tilt-back before 30kph or at 30kph though. Maybe it's there but too slight to notice. So it feels a little scary when those beeps happen but no tilt-back. Do you know what would happen if I were to keep riding at 30kph or push it further? Does tilt-back happen eventually or are we supposed to just slow down at the moment we hear the beeps?
  5. Thanks to MRN76 for making this App. In my experience updating my S1 to an S2 took only a few seconds and added an extra 8kph to my top speed. Upgrading to firmware 7.6.0 for a top speed of 30kph was more difficult with my phone and took 13 attempts (which all took over 30 minutes each) but it worked in the end. I believe that not everyone has this problem and that it may depend on the phone that is used. If anyone is having the same issue I recommend you to keep trying. Even if it seems like it is never going to work, it probably will after enough attempts. Thank you once again for the work that went into this mod and for the fact that it doesn't require us to take apart our wheels and modify the hardware.
  6. I have read the whole thread. The information is scattered throughout this thread. It would be great if someone could do as I mentioned in my previous post so that there are clear instructions laid out all in one post.
  7. I want to thank everyone who made this a reality. It's a fantastic piece of work. I would like to do the upgrade on my own S1 and make a monetary donation to the cause. Has anyone (or would anyone mind going to the trouble to) put together a simple and clear step by step tutorial for this in English for people who don't know what a J-link is and have never programmed a motor controller? Something like: 1. Buy this product (link to programmer) 2. Disassemble Unicycle 3. Solder the following wires to the following locations 4. Whatever the next step is And so on.

    These look interesting, intriguing and very portable.

    400km and still waiting on first crash

    If that's truly what you think then perhaps you should think a little more about it. I can assure you that when a 14 year-old falls off a park bench onto some firm grass the risk of breaking bones, puncturing a lung or sustaining internal bleeding is much less than when an 87 year old does it. Likewise, when a 50 year-old falls off a skateboard there's a substantially higher risk of injury than when an 18 year-old falls in exactly the same way. When people are young they are more flexible, more supple, less brittle and heal faster than when they are 40, 50, 60, 70 years old. Your examples of sustaining your worst injuries at sub 5mph are under quite particular circumstances. You were still learning, you were riding a low power, less reliable EUC and you were hopping off or onto a curb. When I was learning I fell off (or jumped off) at low speed many times. I did not ever feel in danger of any injuries that would cause me tears. The speed was just too low for me to worry about breaking a leg or losing teeth. Now that I have a year under my belt and something like a decade of e-boarding behind me I am still ultra careful. I have no desire to do tricks or ride backwards. I never forget that my wheel could cut out. In some of your videos you ride close to and past pedestrians in a way that I personally think is too close and not careful enough. I have seen you act less considerate of others than I would be in the same environment. I'm not saying you ride like a maniac (you absolutely don't) but you take more risks with other people's safety and comfort than I do, in my opinion. I think it's hypocritical to be shaming me for not gearing up when I see videos of you riding around populated areas in shorts and a T-shirt - no knee pads, no wrist guards, no helmet, going forwards at speeds higher than I can go and even riding backwards, which adds further risk. I'm sure you wear gear when you ride the Monster but I would hazard a guess that I would come out less hurt falling off my 18kph EUC without safety gear on than you would when falling off your 55kph Monster with safety gear on. By choosing a much faster wheel you are already taking on more risk, helmet or not. I'm at risk when jogging through forest trails because I may trip over a tree root and fly head first into a sign post or tree trunk. Still, I do not jog in a helmet and knee pads. We take calculated risks every day we get out of bed. One has to find a balance between safety, practicality and comfort in everything one does. If we hurt ourselves, that's one thing. But the more important thing is to not put others at risk, as they have not chosen to take the risk of injury at our doing.

    At under 5mph I wonder how much all your safety gear helped during those ultra low speed falls. And I wonder how much experience you had with sports that require balance before you started into the EUC hobby. I think age makes a big difference too. I cannot imagine falling off my EUC at 4mph in the locations where I ride and sustaining my worst injuries. We're talking about falling over at walking speed. It would have to be a very unlucky set of circumstances to do major damage. I could break my back climbing the 3 small steps at my front porch but I'm not going to start wearing a helmet and back protector to pop to my mailbox every day because there's a very small chance of injury climbing those steps. And I'm saying this as someone who has had skiing, snowboarding, motocross racing, power-kiting, push-bike, electric skateboard and road motorcycle accidents. I think when I am your age I too will be fully kitted out with knee-pads, helmet, wrist guards and that little cape you wear at the back of your helmet to protect you from sun damage. We get more fragile as we get older and that's something to consider when doing any sport that involves the risk of impact. I already feel much less robust than when I was 19. If I get an EUC that cruises above 20kph or just any kind of Gotway, I'm going to be wearing some gear. But when riding my current EUC which cannot keep up with joggers, away from traffic, I feel ok without gear on.
  11. I thought I'd update this as it has been a year since I started using it. The metal enclosure of the Mk1 (main thread here: https://forum.electricunicycle.org/topic/7220-portable-universal-charger/ ) was bigger and heavier than it needed to be and was bulky in my now smaller backpack. So I made a very small enclosure for the circuit and I now carry the watt meter in a separate pocket of my backpack. This is a much less bulky way to go. The watt meter is not strictly necessary as the converter is set to 62.95 volts with a current limit of 2 amps, which is ideal for my Segway One S1 and my MiniPro. But I like to monitor what's going into the EUC when I charge on the go so I don't have to rely on the app for charge status (which in the past has been blocked when Ninebot's servers were down), so the watt meter comes with me most days. With the slim Lipo packs in my bag and this portable charger I know I have enough energy for at least 50km of real world riding. This all stems from the range anxiety I got in my early EUC days after I had to limp home at 4km per hour when my battery dropped to single digits on a long ride. The heat sink is exposed and it seems to stay cool enough to not need the fan anymore, reducing size further. I sort of feel like I can go anywhere, without worrying about range. The Drok boost converter has been working very well for over a year now and is well worth the $36. )

I very much recommend anyone else building a similar setup if you like the portability and light weight of small EUCs but don't like the limited range. For me this gives the best of both worlds.

    400km and still waiting on first crash

    I have over 1500km spread over two EUCs and a Segway MiniPro. I haven't crashed yet and I haven't had a power cut yet, thankfully. My machines have all topped out at no more than 22kph and I usually only ride on empty country roads and park trails, so I have not felt the need for safety gear. My current wheel does under 20kph, which feels slow to me coming from many years of riding electric skateboards at 40kph and electric bikes at 50kph. But bikes and skateboards don't throw you down when the power is lost, so EUCs are much more dangerous than both. At 36kph on an EUC I think I would feel the need for wrist and head protection. I have seen people on this forum wreck themselves falling off at speeds around there.

    Ninebot A1/S1 to S2 Upgrade Effort

    I'm just waiting to see someone successfully do this on an S1, to know that it works, before trying it myself. Also, with the language difference it's a bit harder for me to follow using Google Translate.
