Could you post some more pictures, preferably ones that aren't upside down?

What kind of metal did you make the frame out of? I'm going to make something like this soon but am not sure what type of metal to use. Thanks.

Check to make sure you match the bottom bracket size. Bbshd has 68mm, 100mm, or 120mm (pretty uncommon). I would ask the bike seller which size because you need this to match or else the bbshd won’t fit.

Ok I figured it out! My Mxus needed all phase wires to match but swap green and yellow hall wires. Runs like a champ now! I also set the hall angle to 120 but I don’t think it really did anything. Please note that I never got the angle test to succeed...I just wired it up and tried the value of 120 ...

Halls were definitely fried. I ordered these as replacements: https://www.amazon.com/gp/product/B00IFD0F7M/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 They work, but I still can't get my hall angle :( I'm getting the "fail 3" error now instead of "fail4" which is actually a good thing. Apparently "f...

Have you checked manually checked the hall sensors toggle on/off when rotating the motor slowly by hand? Those 10 dollar motor/controller testers are very useful for trouble shooting hall sensors and their wiring! I just completed an additional test and have discovered that my green hall sensor on ...

I just don’t understand how there can be a hall fault when all 3 halls are reading 3.2v and the power connector is getting 5v. There’s clearly not a hall fault, yet it won’t stop giving me the error no matter what set I try. I even opened the motor and tested continuity between each hall sensor and ...

Thanks again for all the suggestions. I’ve tried hooking up my old Kelly kls7212s and it gives me the same error as sabvoton: hall fault. Ive measured voltage as 3.2v going to the hall sensors (both sets) so I really don’t understand what the problem could be. When I run the hall angle test, it move...

Some discussion here on similar Sabvoton issues but not any solution https://endless-sphere.com/forums/viewtopic.php?t=92558 Perhaps its a software issue. Have you tried a factory reset? Is there a way to reflash the firmware? It appears that these controllers have their fair share of problems thou...

I don't have a Sabvoton yet, but I read about a guy who got it working by lowering the motor curent to something like 16A then testing it. After the test I guess you can put it to whatever you like. Thanks for the idea but I've already tried a multitude of different amp values ranging from .5 all t...

Does anybody have experience pairing a sabvoton 72150 with a mxus 3k? I had my bike up and running for about 3 months using hall angle degree of 53 but I took it apart recently to change the connectors on the battery to XT90's however the controller lost its programming when I turned it back on. No ...

Update: I opened the battery this weekend to discover that there are indeed 9 parallel groups of 20s 2150mah batteries in here. This means LAebike did not lie about the AH rating, but the 20s7p/140cell count was wrong. Lesson learned here- when spending $1000 on a battery, reach out to a recommended...

Thank you to everybody who has contributed to this thread. LAebike has had a message on their website for months that they are moving storage facilities and will not be able to respond to emails very often. I will be taking apart the battery pack this weekend to discover if they lied about the AH ra...

That amount of sag is killing your batteries, because they must be getting hot. I draw 150A, with a 31s pack and the most sag I see is 5V, and I have blistering acceleration not remotely possible with a more standard geometry bike like you guys are running. The pack is 22ah 115V nominal with automo...

Sounds like they are overrating their packs. The maths just doesn't add up. Right - the math isn't right. I'm crossing my fingers hoping that the listing is in error and that the pack is actually 9P and not 7P. If it isn't 9P, I'd be pretty upset with them. I emailed LAebike about this on July 14th...

Yeah, it happens on full charge also. The battery stopps chargeing at 82,6v i think. Going to chek when it's full. The volt has never dropped under 70V on the monitor. I have never used more than halfe the power, before chargeing. Hmmm are you familiar with "voltage sag"? Voltage sag occurs when yo...

What brand throttle are you using? If it ever suffered water damage it could be causing the sensors to fail.

Well stock bbshd power rating is max 60v 30a so I bet the fuse is 35a. This is probably to keep people from running too much power through them without buying the “ludicrous” version.

For a mid drive - internal gears and clutches are the failure point. For hub motors - heat is the enemy. Most hub motors can be run for a few seconds at 2x-5x rated power. Mid drives will usually break if you run more than the rated power through them.

I got the bike yesterday, and i'm happy with it :D It feels safe, i had it in 90 km/h on a road with lots of turns, and it felt good. the brakes are okay not great but more than enough for it not to. be a safety issue. The only issue i have, is that on the highest power setting, the motor Sometimes...

Thanks for the info! Neptronix- They are samsung 22p, supossedly rated at 10a continuous I'll continue to play with the settings. Currently waiting for new brake pads to come in so it's just sitting this weekend. It's almost 100 degrees each day this week in Philly so my ride time will be severaly l...

I read through every post I could find about voltage sag but I'm still unsure if I'm experiencing too much. I have this pack from LAebike: https://laebike.com/collections/72v-18650-lithium-ion-battery-packs/products/72v-20ah but I feel like it's not quite delivering the advertised power rating. I'm ...

I have this frame - or at least one that looks exactly like it, it's not an EEB one or EM3EV one, but is holding up pretty well (survived a few knocks!). It is steel construction, I bought off a guy advertising on here and paid $350 shipped which I think is a bargain ( https://endless-sphere.com/fo...

I don't see the pictures you linked, maybe try using imgur to upload them?

I recently installed the moto seat and have no use for my seat post mount; I'd be willing to sell mine, PM me and we can discuss this.
