MrMonoWheel Posted January 4, 2023 Author Share Posted January 4, 2023 It seems the JB weld may be holding for now. GTKing has shipped the replacement part as well as the seat/pads I ordered, I am surprised how fast it was taken care of. On another note, I measured the diameter of the phillips screws that are located all over the sherman S (around 40 of them) and it came out to 3.78mm with a length of 10mm. I believe this corresponds to a M4 x 10mm bolt, so I have ordered the follow pack of stainless button head hex bolts to replace everything with. https://www.amazon.com/gp/product/B084Q8YRY8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 Another observation, when I have the wheel standing and slowly press down on it there is very obvious stiction occurring, however this is not felt when riding. I don't believe this an issue as its almost impossible to make a suspension system with no stiction. I will keep my eye on it though. I also noticed that the black countersunk screws that hold the battery housings to the shock towers had some metal shavings underneath when I removed the housing. Upon closer inspection it seems the black screws are just about reaching the end of the threads causing some metal to be cut away. These screws could be 2mm shorter to alleviate this issue, although I don't think its a big deal. 1 1 Quote Link to comment Share on other sites More sharing options...
techyiam Posted January 4, 2023 Share Posted January 4, 2023 3 hours ago, MrMonoWheel said: I have to revise what I had said earlier. When I had spun the wheel I didn't have the plastic mudguard support and stanchion mount bolted to the axle. It seems now after having all that connected it puts some pressure on the rubber seal preventing it from turning, so it infact stays stationary. Thanks for that. With the initial piece of information, I now know that the sealing surfaces are not on tight. That is good to know. But with external pressures, the seals can stay stationary. 1 Quote Link to comment Share on other sites More sharing options...

Popular Post MrMonoWheel Posted January 4, 2023 Author Popular Post Share Posted January 4, 2023 (edited) I've been tinkering with the wheel and decided to address the issue WrongWay experienced of the buzzer dying due to water ingress (although he was also riding in ice/snow/salt). The buzzer is a cheap SFM-27 piezoelectric buzzer and can easily be replaced. As it comes it's wide open to the elements. The back of the buzzer is a paper sticker covering the back of the PCB, and the plastic housing has two small holes on the side as well as the wide open front. The place the wires go into the housing also needs to be sealed. I smeared silicone all over the back of the PCB to seal it into the housing, filled the holes on the sides, and pushed a bunch into the hole the wires come out of. As far as the front goes I put a thin piece of packing tape over it and cut off the excess. Still let's plenty of sound through.

Popular Post MrMonoWheel Posted January 6, 2023 Author Popular Post Share Posted January 6, 2023 Replaced the Phillips screws with stainless button head hex screws. The heads on these are 7.22mm vs the stock 6.57mm so it's a tight fit but they fit. The only place they aren't gonna fit is the screws that hold together the ratchet mechanism but I don't care about those since I removed the mechanism in the first place. I'm trying to find some with smaller heads that use a 3mm hex instead of 2.5mm but for now these are good. Something to watch out for is that the plastic they make the motherboard cover out of is very soft and thin around the screws. This causes it to easily deform and split when tightening, even when not making the screws very tight. I've resorted to just snugging them up till I see the cover make contact with the metal, and relying on threadlock to keep them in place. I really wish this was made from metal. 4 3 1 Quote Link to comment Share on other sites More sharing options...
Clem604 Posted January 7, 2023 Share Posted January 7, 2023 (edited) @MrMonoWheel Thanks a lot for doing this disassembly and all the other things. It will be a great benefit for us whom are waiting for their wheels to arrive. I'll be sure to look out for the things you've pointed out.

MrMonoWheel Posted January 7, 2023 Author Share Posted January 7, 2023 So today I was doing some riding and realized I have yet to hear beeps while riding. I got the wheel down to 40% battery and was still cruising at 40mph without an issue, so I loaded up EUC world. I turned on "Use wheel alarms" assuming it would alarm in the app at the same time the wheel beeped, but that isn't what happened. The app was having alarms go off at 16-20mph while the wheel still wasn't beeping all the way up to 40mph (I didnt push further). Am I doing something wrong in the setup of the app? 1 Quote Link to comment Share on other sites More sharing options...

LK doesn't transmit that sort of stuff over bluetooth so things like use wheel alarm will not work, you will have to setup all your own values there, since Sherman S is a brand new wheel I don't think anyone can give you the best values to put there you will have to do some trial and error, safety margin is a good alarm to play around with, start with 20% and go from there. To test if the beeper on your wheel works you could freespin the wheel. 2 Quote Link to comment Share on other sites More sharing options...

Do you think it could be useful to use flat watchers (nylon, rubber or something else s material) with all the screws to prevent this issue and the one you already experienced with the broken metal cap?

I considered that as well but it wouldn't help since the problems are from the material failing under torque of the screws. The metal cap cracked pretty easily and the motherboard cover is just very soft material. Quote Link to comment Share on other sites More sharing options...

High speed mode needs to be added via a firmware update. Download this app (android required) and update the firmware, then it is in the menus. https://github.com/Leaperkim/Updated-APP-Firmware/blob/f156f48f606fcb20bda0d4cd9733199cfe510df7/LeaperKim-1.0.3 221206.apk Suspension adjustment is pretty straightforward, but I've left mine stock and it's fantastic. Adjust to suit your liking, perhaps start with static sag and go from there. 1 Quote Link to comment Share on other sites More sharing options...

lucaluca Posted January 10, 2023 Share Posted January 10, 2023 3 hours ago, TheNotoriousEUC said: As someone new to much of this, does this mean there is no App from / for Leaperkim for Apple? Yes, no apple support and I wouldn't hold my breath on support coming soon anytime. Even the android app is not the most reliable and is not available in the playstore. So you have to download an english version that was translated by someone from the community and is on github. So bluetooth app and support is far from optimal and a far cry from the likes of Inmotion, KingSong and Begode. If you use the github version for firmware updates, be sure to read how to use it and set it up properly to minimize the chances of a bricked firmware due to a failed update which would render the wheel temporarly unusable and can be quite a pain to unbrick. There is telemetry coming from the wheel via bluetooth but almost all settings need to be setup via the onboard menus on the Sherman if you want to change them. No remote control of the wheel but you have access on Eucworld or DarknessBot to speed, battery information and more. The last two apps are not from the manufacturers and are the go-to apps that are compatible with many wheels and are constantly updated with a host of features but vary between wheels. While bluetooth app is unprofessional and a weakpoint on Leaperkim wheels, on a daily usage it doesn't matter that much for most riders as it is easy to change settings on the wheel via screen/menus. Just be carefull if you want to do a firmware update and it is better to wait and confirm with others on the forum that the firmware update is working. 2 Quote Link to comment Share on other sites More sharing options...
meepmeepmayer Posted January 10, 2023 Share Posted January 10, 2023 What does the "high speed mode" do? Reduce some safety margins? Quote Link to comment Share on other sites More sharing options...
Popular Post lucaluca Posted January 10, 2023 Popular Post Share Posted January 10, 2023 (edited) Quote What does the "high speed mode" do? Reduce some safety margins? Yes, it reduces safety margins and puts more load on the motherboard and the batteries. Only time will tell how the wheel behaves. I think plenty of people unlock this mode when they receive the wheel and look forward to added performance. But only the people pushing the wheel at the limit on a regular basis will be able to give feedback if this mode leaves enough safety margin. I would like to know if there is also added performance at slower speed with a boost in acceleration or if it just allows for a higher top speed. The former interests me but i can live without the latter. Edited January 10, 2023 by lucaluca 5 Quote Link to comment Share on other sites More sharing options...

Github App is sketchy and my phone has too much sensitive information 2. There are 2 apk files, I didn't know which one to choose. (Glad I stopped... forgot wrong firmware update can BRICK your device) 3. RogerEUC mentioned LK was using "Phrase Vector" (can't remember the exact words) to get higher speeds out of the motor. My buddy who knows a lot about electric motors states, yes, that will work to get a higher speeds but at the cost of energy consumption and torque. Note: this is all speculation or if it can be turned off at low end to get torque and turned on at the high end. Lack of information I can wait for Beta testers/early adapters to figure it out. 3 Quote Link to comment Share on other sites More sharing options...

Popular Post MrMonoWheel Posted January 11, 2023 Author Popular Post Share Posted January 11, 2023 Small update. I've been meaning to take photos of the screws that hold the battery housings to the suspension as the screws are too long and start threading into the main body of the suspension, but Jeremy from the veteran telegram group sent some pics of his today. In this case the screw was bottoming out in the threads causing the head to shear off. I haven't had the heads of mine shear off but I did find metal shavings behind the suspension when disassembling, which came from the screws chewing their way into the aluminum shock body. The stock screws are M6x14mm countersunk screws and I am replacing them with 12mm long stainless hardware. https://a.co/d/ioULcCB 4 Quote Link to comment Share on other sites More sharing options...
