meepmeepmayer Posted October 19, 2023 Share Posted October 19, 2023 151.2V 2700Wh makes sense, it's 36s4p, so that part works out. What exactly does 18'' mean here? 12 inch rim (like Patton, which is often called "18 inch") or 14 (like Sherman-S, with the traditional "18/20 inch" tires)? Any other information? 2 Quote Link to comment Share on other sites More sharing options...

meepmeepmayer Posted October 20, 2023 Share Posted October 20, 2023 Oh so it's 20 inch. Cool. And understandable - the most popular tire size (at least among enthusiasts) but they have no "normal" battery size, just the expensive Sherman-S which not everyone may want. I hope they offer a 4000Wh 6p version, too. Would be a nice Sherman-S successor with a much higher voltage. 2 Quote Link to comment Share on other sites More sharing options...

Popular Post Paradox Posted October 21, 2023 Popular Post Share Posted October 21, 2023 (edited) Ok, it's been a few days since this leak. Why hasn't Begode announced their 3 new models with similar or higher voltage that beat this Veteran Lynx to market?

techyiam Posted October 22, 2023 Share Posted October 22, 2023 (edited) No, rush. No CGI even yet. Any new wheel leaked or announced now won't be available until 2024. In fact, I think Inmotion made another mistake. They announced their wheels too late in the year, or too early for the following season. Inmotion's competitors always seemed to be able to push out wheels that are more appealing by the time the wheels are available for purchase. The key is for new wheels to be available when most riders are wanting to buy a wheel, and also, is a wheel the market is interested in buying. And right now through winter, unless you are in Australia, it isn't peak season. The problem is that after see Inmotion's offering, the competitor can make some changes if required to better compete before announcing theirs. 151.2 V, 4P, 20" wheel from Leaper Kim is looking good on paper, and must be catching some people's attention. Begode don't need to rush. They need to get it right. It doesn't look like Begode is caught with their pants down since Chance said that Begode has been working on a system that is higher than 150V, so on paper, it looks competitive.

Drunkard Posted October 22, 2023 Share Posted October 22, 2023 As much as it's funny to meme on begode that they now scrambling to put out 3 new models in response it's kind of scary that they probably are.. With higher voltage I'm quite expecting either the new LK wheel or the BG response wheels to start pushing 100km/h riding speeds. And i'm not sure i trust BG to deliver that in safe manner lol.. 1 Quote Link to comment Share on other sites More sharing options...
techyiam Posted October 22, 2023 Share Posted October 22, 2023 (edited) No worries. As before, plenty of people will share their highest top speed runs on YouTube, and whether they crashed or not. Over time, we will have an idea which wheel can go how fast. Crashes over 100 km/h have already been shared. So it is survivable. Moreover, there will be someone who will mod the wheels to go even faster. Since, motorcycle tires can be use on these electric wheels, at least we know the tires can easily handle 100+ km/h speeds.

Velcro glue is melting off everything. There was a road we all rode our bikes on and last year the road started melting. "Another case is the recent roadworks on the western approach to Mt Glorious, South East Queensland. Less than a month after the roadworks were finished and the road returned to 80km/h, hot weather caused the road to literally melt. This left the new roadworks treacherously slippery for motorcycle riders." 2 Quote Link to comment Share on other sites More sharing options...
Popular Post Rawnei Posted October 23, 2023 Popular Post Share Posted October 23, 2023 What I hear on telegram is that several riders globally are already getting their test version air shipped right now, Marty is one of them, and that launch should be Q1 2024, so we will probably get more solid information and confirmation soon. 6 2 Quote Link to comment Share on other sites More sharing options...

Hopefully it will be year for a great leap in safety and quality. Indeed. Every year is an exciting year for euc. It started as a low-quality toy, and now we have an actual vehicle that can compete with cars and motorcycles as a transportation device. It is crucial to fine-tune this tech by making it faster and more powerful, which requires more investment in safety features. That eventually will be applied to the smaller wheels as well. 1 Quote Link to comment Share on other sites More sharing options...

Popular Post CrabChampion Posted October 27, 2023 Popular Post Share Posted October 27, 2023 Looks like a bigger patton. Anyone else not that interested in 150v? There is no adjustable fast charger (GTK, Huawei, ningning) that goes up to 150v. They all max out at 140v. Means most will have to buy another charger for this wheel when the adjustable charger was supposed to cover all future wheels (atleast thats why I bought mine). 150v also means you wont be able to pull as many amps out of a standard outlet due to the higher wattage. 126v and 134v wheels feel plenty powerful enough and leaperkim proved that voltage isnt everything with the sherman-s. Firmware refinement can actually lead to more power. Are we still playing the voltage arms race? I hope atleast this wheel will finally be leaperkim's first smart bms wheel 8 Quote Link to comment Share on other sites More sharing options...
zaft Posted October 27, 2023 Share Posted October 27, 2023 It looks like it has significant suspension travel and looks robust. Would be interesting to overlay Sherman S profile image and compare some traits. I imagine the charger will have a boost converter in it for that voltage Quote Link to comment Share on other sites More sharing options...

We're using typical switching power supplies with a first stage at or above 400VDC. And we're only interested in the total charging power, which will be limited by the AC service (e.g.: 1800W for USA residential 15A@120VAC). 1800W would fully recharge a 2700wh EUC in about 2.5 hours, no matter if the battery is 84V or 151V. * but we don't charge quite that fast anyway... cells would get hot. More typically: charging at 900W. Output DC voltage can be lower, or higher, than input AC RMS voltage. There is no direct relationship between the two. Nice intro to switch-mode AC-DC below: Quote https://electronicsbeliever.com/switching-power-supply-operation-principles-and-design/ AC-DC Switching Power Supply Block Diagram Below is a two stage AC-DC switch mode power supply block diagram. The first block is a bridge rectifier which purpose is to convert AC to pulsating DC. In contrast to a linear AC-DC power supply, this bridge rectifier requires high voltage rating since it directly see the input voltage. The first stage switching converter is most of the times a boost converter which functioning as a power factor correction circuit or PFC. Boost converter has an output of higher than its input. Power factor correction is needed for switching power circuit to correct the shape of the current and minimize harmonics. Boost converter is the best active power factor correction circuit because of its ability to draw current from the input in both state of Q1 (on or off). The second stage switching converter is commonly called a DC-DC section by power supply manufacturers or designers. There are lot of topology available for DC-DC like resonance (LLC, series, parallel), forward (ITTF, TTF, single transistor), bridge and full bridge to name a few. In the diagram below, the DC-DC section is an LLC resonant converter. The last block is the output rectifier and filter. For high power applications, NMOS are used instead of diodes.
