Popular Post Flying W Posted October 16, 2022 Popular Post Share Posted October 16, 2022 My RS has been great, but sometimes I forget about all the initial checking of everything to get it as right as I could before even taking that first ride. There were crap quality screws that were all replaced with stainless. Wires and cables that needed to be re routed. Bearings that needed to be packed with proper grease. Fan relocating so it wasn't jammed on top of a pedal bolt just waiting to be cracked in a low speed tip over. Dust ingress points to be sealed. I'm probably forgetting other things too. This is on the best built gotway I've had too. At least it has screw inserts on the side panels. After all this the wheel has been trouble free for 2600 miles now, and with the new packs from the battery recall at ewheels it is basically an almost new wheel. No one getting a wheel for the first time is going to do all this ad a basic once over before riding. There should be a common disclaimer on all "influencer" outlets right at the start telling people new to this what they need to be aware of. Back in the 18 to 22mph days this wasn't as bad. A failed wheel would hurt ya but was limited to cuts and bruises if wearing gear to maybe a broken collar bone, wrist or arm. Now days a 35 mph wheel is considered slow and a lot of new people are going for the latest and fastest. And these new wheel are way less dependable. We didn't have V8s and 16s's failing all over the place in normal riding scenarios, but these new wheels can just drop ya for almost no reason. I really think those that are not willing to take these apart should wait until the bugs are out, but that means always having yesterday's wheels and that's just not the fulfilling the latest n greatest itch. A Co worker who had been looking into this because I ride to work most days asked me when he should get. I recommended the 18XL. He asked me "how fast does it go"? When I told him he just shook his head and said that's not fast enough..... 5 Quote Link to comment Share on other sites More sharing options...

Remind him he's riding one wheel device, that is smaller than suitcase. And ask him again if it's to "slow". 18xl is one of best wheels to get as their starter, or one and only wheel. As someone who used regular bicycle for riding around ~25mph is fast enough. Also if you ride faster - you need more safety gear. 1 Quote Link to comment Share on other sites More sharing options...

T4 sliders are sticky ala s22, I hope I will fix that. The shock is little better - since it is really working this time - but still shock needs to be replaced. I am looking for fox one for right price. Life is to short for troubleshooting and tuning begode shocks. it is different bag of chocolate not a better one ! Ok, it is still better than s22/v11 - but not better than my modded s18 with spring. Edited October 17, 2022 by daniel1234 1 Quote Link to comment Share on other sites More sharing options...
Popular Post daniel1234 Posted October 17, 2022 Popular Post Share Posted October 17, 2022 (edited) After DIY drilling into EUC hub motor - many hours of cursing I got T4 running again. I felt like crash test dummy - took all protection gear so I looked like batman and tried to slip it statically and dynamically at the same place as before. I tried even pushing EUC to pedal dip and PWM warning. Seems sable. There is a little woable on hub (not sure if it was there before - I didn't check for that first 50km - it could be better than before), but not noticeable during a ride. Far for perfection -> I will replace the bearing set on the next hub dismantle. Nobody should have EUC experience like I have. If there is so much time and testing needed to get EUC running I can build one from scratch on VESC platform! Every day with no response from begode I am losing my hope for EUCs. Low-end torque is a lot weaker than master, but better than s18 (at least something positive). Acceleration is fine -> I guess acceleration is making that wheel feel nicely zippy. Pedal clearance is perfect with formfactor - feels like small Sherman with suspension. I managed to kill 50 percent battery in hour of climbing hills and stairs. I noticed power dip on low battery and some weird FW behavior. It reports current incorrectly for example ... Dip sometime up stairs before 80 percent PWM ... FW update is probably necessary...

What code has motor in post above where you describe all story and details ? ZX or QS ? Edited October 18, 2022 by Meserias Quote Link to comment Share on other sites More sharing options...
daniel1234 Posted October 18, 2022 Share Posted October 18, 2022 zx... I did another 50 km on DIY repaired hub - there is still some sound I don't like. I need to take it apart again and take a look to be sure. Better safe than sorry. This time I will go crazy and drill the whole stator through and find some ferromagnetic rods, so it will not affect overall flux or inductance. Anyway - if I ignore technical issues: T4 is fun to ride, I like 16inch form factor for the sidewalks ride. From 15 km/h it is really zippy, but I missing just low-end torque for jumping. Is anybody have T4 with QS motor ? I am curious how much torque it has... 2 Quote Link to comment Share on other sites More sharing options...

daniel1234 Posted October 21, 2022 Share Posted October 21, 2022 Has anybody figured out how to mod sliders to go up/down smoothly? Or how is your suspension working? When I take the shock out it is not working as expected.... yeah it works somehow ... bad not as my master/s18. 1 Quote Link to comment Share on other sites More sharing options...
daniel1234 Posted October 21, 2022 Share Posted October 21, 2022 ok found the problem - hub motor screw head, damaged carbon-brass slider insert. Omg I should design my own EUC. This is getting ridiculous. feels like fixing everything : Motor, suspension , electronic, reflash fW ... It is like a science kit . 1 Quote Link to comment Share on other sites More sharing options...

RolluS Posted October 21, 2022 Share Posted October 21, 2022 38 minutes ago, Cerbera said: Why will it fail ? Because it's not black as the one of the master? just kidding. To me it seems it's the same nylon socks technology on both. We know stator slips, we know bearing have (still since RS) issues with water, we know sometimes bolts can grind suspension guides, but we have yet to see (unless I've missed it) this cable to fail at this place. 1 Quote Link to comment Share on other sites More sharing options...
Cerbera Posted October 21, 2022 Share Posted October 21, 2022 If it's anything like the Master it is clamped at both ends, strongly shielded, not trapped by anything, and is designed for regular flexing. I think this is very unlikely to be a fail point unless we damage it in a crash. 1 Quote Link to comment Share on other sites More sharing options...
RolluS Posted October 21, 2022 Share Posted October 21, 2022 (edited) It is clamped there (in background, behind headlight): And here: Some like to upgrade with black nylon mesh or plastic spiral. Personaly, I'd just paint it black Edited October 21, 2022 by RolluS 1 Quote Link to comment Share on other sites More sharing options...

The cable could fail after some use, because it flexes just at the bend. It should distribute flex along whole length of free cable to last longer. 4 Quote Link to comment Share on other sites More sharing options...

It shouldn't make new hard bending points. There has been several cases where spiral wrap was installed just for added security, and ended to reduced durability. In Master and T4 the spiral wrap should go under the mounting bracket at the control box. 2 3 Quote Link to comment Share on other sites More sharing options...
