    Here's a few clips from my typical daily ride on the beach bike path through Hermosa Beach, King Harbor, and Redondo Beach in California. It's my first attempt at a video. Still trying to figure out the angles.

    Long story short: I got tired of people asking me "what is that?" so I made business cards advertising this site. I hope you guys don't mind. If you want to print them out yourself, I've attached a Microsoft Office Publisher document that you could use to print these cards out on regular paper. Publication1.pub

    With your Kind of damage i would let Ian repair that! A complete Motor and board Change you will certainly not like to do.... Very good that they Change the complete Motor, cause who knows how far the wires are melted even inside the Motor!

    The wind was crazy today! I saw a sailboat get tossed into the King Harbor pier by a big wave. All four passengers made it to shore.

    You say GW will spend a new Motor...and a new board. I would guess that a new Motor, means just the Motor, no rubber tyre, no pedals! So you would not only have to completly dissasemble the ACM, also you are needing to Change the tyre and the pedals to the new Motor. As your Motor cables are burned/melted very hefty, a Motor Change is a wise Thing! Otherwise you risk that the wires are not only melted where you can see it, they couls also be defect inside the axle, where they are "packed" the most! This dont have to be, but at least -if no complete Motor Change-i would inspect inside the old Motor then.... Then also: You have had a very respectable short because of the melting...who the hell knows if not some parts of the boards are damaged now! That said...that is all work for the seller...in my opinion! Beside the shipping costs: From German law that would be the sellers part, also! But as this was a european Business...i would not insist on that..perhaps yoou pay sending to Ian...an he when sending it back to you.... What i find a bit unusual is that Ian didn't say anything more about it....after he posted the "footrest braking" photo/warning on his Website...i would exspect that he warns his customers about very hefty or Long steep inclines, also!

    What you describe here applies to almost any EUC. None of them are safe and can be dangerous. Just saying.

    Wow, that's some incredible footage that you shot. Only a few views - you need to post it somewhere - that's the makings for a viral video They must have been terrified when it was capsizing - glad they weren't injured (which is amazing)

    Omigosh, I've never taken sailing lessons before, but are you supposed to have your port or starboard side facing the waves directly like that? I guess with a wave that large hitting it with the bow at an oblique angle would have flipped it anyways? @meepmeepmayer - I think it'd be my dream to quit my day job, hit Jason McNeil up to hire me to do an RV Mobile EUC Demo tour of the US. I'd tow a small trailer with a bunch of different EUCs selling them off where ever I stop. I'd get a Mavic and document my trip on Youtube. I actually took a month long trip down the Oregon coast just hitting the State Parks and meandering my way almost down to San Francisco. It was a great trip, and the EUC would have come in super handy as getting firewood and hiking along all the trails takes so much time. @Joey Serrin That Sherpa is CRAZY! Excellent concept to design work. It's so cool that you got all the batteries and everything inside the wheel. Now that's thinking um inside the wheel? Outside of the box? I'm confused... Sherpa Golf anyone?

    Here one of my designs. I call it The Sherpa. **Coming Soon is an offspring of MAX and Sherpa** eta 1 month

    Using a simple Inclinometer app on your phone should provide you the incline (lay the phone on the ground). Thousands of ACMs have been sold and apparently working in the vast majority of the cases. You have the bad fortune to experience one of the outliers. Get it fixed and then enjoy the wheel

    Let me share pictures of EUC motors: - https://github.com/EGG-electric-unicycle/documentation/wiki/Motor - https://github.com/EGG-electric-unicycle/documentation/wiki/Motor-EUC1 - https://github.com/EGG-electric-unicycle/documentation/wiki/Motor-EUC2 - https://github.com/EGG-electric-unicycle/documentation/wiki/Motor-MicroWorks-500W-30km-h Isn't possible to use the spare holes?? If please note that the space between the hall sensors should be the same as original. I am not sure on this but I believe hall sensors are just used on very low speeds and for changing direction, after than that, the firmware will switch to an observer and ignore hall sensors signals - there are some advantages, like avoid any possible problem with all sensors when going at high speed, since at very low speed should be not big issue. Unfortunately I do not have any good idea to resolve your current issue, other than what others already told: remove the hall sensor and replace with a new one (like the references talked before). I think they are "kind" of compatible with most of them. If the signals are just use for slow speed, there should be no issue for the firmware to have ones that differs a bit between them. I really love all the information you are sharing!! IMO, the power cables insulation against high heat are the best improvement. About board temperature, at least MicroWorks board reads the temperature and protects the system with it goes high: https://github.com/EGG-electric-unicycle/documentation/wiki/MicroWorks-30B4-30kmh-controller-board-with-bluetooth#Max_temperature_protection Good luck!!

    Are you alluding that my warranty has been compromised? I agree with the consensus!!! Send er Back! If you decide to send it back we may be able to speed up the shipping process. I am having trouble finding parts in the US so I am taking the Gulfstream G650 to China. There is plenty of room for you and your busted wheel and a stop over to see Ian would be no problem! Seriously, like @Hunka Hunka Burning Lovepointed out I would inquire about shared shipping costs as round trip could be expensive!

    I'd vote for sending back to have it repaired if you aren't familiar with working on electronics. As well for future warranty purposes it's nicer to have the dealer work on it so they can't blame you if something fails again. Are they going to cover shipping or are they going 50-50 on it? They can also do a thorough postmortem to maybe figure out what really went wrong.

    What a bummer that you are required to repair it! What other industry treats their customers in that fashion? And no mention of what exactly caused the malfunction? Did they ask for any of the components to be shipped back for inspection? As for the board, the 3 motor wire leads that exit the PCB should be attached. You will probably have to connect the those wires to the actual motor leads. Hopefully they will provide the connectors! Take lots of photos as you disassemble the wheel and use separate holding trays for each batch of screws as there are numerous sizes and styles. How does this affect your warranty? Best wishes! I will help you anyway I can!

    I am learning a lot about Hall Effect Sensors but I have not been able to locate the exact sensor yet. Hopefully tomorrow. A Gotway representative did email me with a quick note for me to contact the seller. Nice! I don't think The Green Fashion Travel Shop will be of much assistance locating the proper sensor but I emailed them anyway. No response yet. I did find out that the sensors used in the GW ACM are considered 'Latched'. I am not sure about other wheels but I assume they would be identical. Here is a nice little video explaining how these sensors work.

    Standard charging rate for most of the 10A cells used in EUC battery packs (in 18650 format) is 0.5C, maximum charging current is usually 1C. Since the KS16S uses 3500mAh cells, 0.5C would be 1.75A per cell = 7A for the entire pack. Actually, since the capacity to use for this calculation is the minimum and not the nominal capacity, it's more like 3400mAh x 0.5 x 4 = 6.8A I don't know which cells they actually use, but it could be an LG MJ1 for example: https://eu.nkon.nl/sk/k/Specification INR18650MJ1 22.08.2014.pdf So for the KS16S or the KS18, 4A is still well below a standard charge, but for smaller models using only 2 parallel rows of cells and maybe lower capacity (3000mAh), 4A would be more than a standard charge, although still within limits for a 1C charge. I guess they just wanted to keep it simple and define one standard charging method which is OK for their entire product line, or there is a limit imposed by cables or circuits between the charging port and the battery pack. I wonder what Chris from 1RadWerkstatt thinks about it, he would know for sure if the KS16S can handle 4A chargers.

    I'm sure that he's buying the ACM because it's currently the best EUC on the planet

    After now 15 months I am right before the surgery to take the metal back out. What’s left over: arthrosis in the ankle and a lot of experience how to survive surgeries and hospital’s.

    Here's the info I received on the reason to limit charging to 2A. "Seems someone at KS thought it a good idea to route the charging cables through the control-board. It's entirely possible that this new improved layout might not be capable of supporting the 4A charge rate. "

    With the amount of cells the big (parallel) packs have, the amperage shouldn't be a problem, but the GX16-3 is rated for something like 5A max. Going above, you might risk the connector overheating and the plastics might begin to melt 1RadWerkstatt has 8A chargers for the largest packs, but they come with different connectors or multiple GX16's in parallel (don't remember which), because the current is too high for the single GX16. Also, didn't older (not S) KS16's have packs (2 x 16S2P?) that were daisy-chained? If only the first pack in chain is charged directly by the charger current, then the amount of parallel cells there (16S2P?) is the limiting factor, although if it's two in parallel, I think it should still be ok for 4A...

    Sorry I did not get back to you on that! I tried all types of solvents: acetone, mineral spirits, goo b gone, but unfortunately the epoxy they used is really stuck on! I thought about slowly grinding away the epoxy this morning. It would be great to know which sensor they used!

    No! Ian offered to repair, but I could do it myself if I wanted. Thanks for the board clarification. I'll probably still send it to Ian, but not 100% sure yet (only 99%).

    If you weigh nothing and the road offers no friction resistance to the tire, you can go as fast as as the wheel will turn before switching off (which is apparently 65 km/h). I agree with Marty, anything above 40 is very likely a bad idea, and you should trust your sense of safety anyways in how fast you go. Also, even with gear you dont want a crash at 45 or 50. I think it should be safe to try 45 for a short time but I would not do more (it also depends on your weight). In addition, I've had my ACM die on me during a high stress ride (mountain though, not high speed) and it was before there was any temperature warning (I didn't watch the temperature though, but it must have been below warning temperature) so consider that GW wheels may not warn you before something goes wrong. Nitpick: there's a V3s (1300Wh) and a V3s+ (1600Wh), but no V3+

    Yes, I've been riding with @captainwells almost every week. Sometimes we go to Torrance Beach and sometimes to Venice Beach. Always a great ride unless the wind is blowing from the west at 20mph

    I think you @Geowurm and @Bob de Bie have had the worst EUC accidents I've seen on the forums. @EUC Extreme also had a bad collar bone fracture where I think they had to splint it with a metal framework. Can't find the photos though... EDIT: Found it:
