Dope video 💯

Did you run the hall test routine in the mqcon app?

Might be worth checking the balance of the rear wheel might not be electrical issues hard to tell

saw the same video u did, good choises

I have the same bike the only problem I have with it is I constantly have to change out the brake pads bc they squeak a ton and I can really do jumps with it bc it’s super heavy and janky but nice vid dude keep it up 👍🏼

Like he said check your spokes and change the bearings in the hub

How do you install the rear light

How fast the hub motor get hot ? I have 60v3000w hub motor and 60v45-50amp controller and my motor hub get 70deg after 4-5 miles of driving is this normal?

Have you ever fixed that wobbly rear wheel? What caused it?

were can I buy a mqcon controller 72v 150 amp 8000 watt controller from ,am in uk

I just installed my Sabvcon controller SVMC 7260 but I cannot get my bike to go pass 15m/h (25km/h). Would you know if it is a connection error on my part or perhaps a setting issue?

I’m not sure if you fixed the issue with the bike but I’m certain it’s your phase wire combination. Some of these generic motors the color of the phase wires do not match up with the controller and you have to try many different variations so that the motor can run smoothly. Whatever combination you find, you have to also switch the hall sensor wires to match the phase wires.

It’s definitely not the phase wire combination. You can connect them in any order, same as the hall sensor wires (except 5v and ground). The Sabvoton is self leaning. It will learn however you connect it, and from there if its running backwards you just flick a switch in the app to reverse direction. These motors are easy to take apart. It should be checked for check for loose or broken magnets. Not sure if the issue is fixed yet. Lol

It's gonna be a 20s12p pack now they state it can handle 20a discharge but I don't know about that 😂 that's why I'm aiming for 7-10a per cell and limiting the current so the peak dosent go past 15a per cell and 60c for this reason. Aside from the potential drawbacks these cells have amazing value for the money, I'll make a p42 pack eventually and good luck with your build!

@@aaron092000 ,most manufacturers over-rate their cell’s discharge capability, especially if you are in a hot climate. I used some Liitokala 18650s to populate the empty slots in my 13s5p battery kit that only filled 2p of the kit. After unwrapping one cell I found the underlying cells were rated at 10a by the manufacturer but independent testers rated them at 5a, and i find that going over that the pack heats up rather quickly. Once your pack is made you will just have to see how they perform as a pack. Since you have an ANT it’s easy to see whats going on. I find that starting from full charge (4.2v), and setting DC amp peak at whatever sags the cells down to 3.7v, is a reasonable peak value, and then half that peak is probably acceptable CDR rating, which you would use rpm limit to get below that. I think the HG2 is independent tester rated at 3a, which probably means 6a is realistic peak to stay below 45c. But if willing to go to 60c or if you are in a cold climate you can pull more. Even my P42A cells I probably rate at 10a CDR, 20a for 3 minutes, 30a for 30s and 40a for 10a. So as a 5p pack that gives me 50a continuous without going over 45c, 100a for 3 minutes which should be more amps than I can use at top speed, 150a for 30s which is definitely longer than it takes to go from 0 to top speed, and the 200a gives me the ability to hit the 190a peak of the controller but ill probably stay under 180a and set that for 5s boost setting.

Hey buddy I was wondering where you got your new Sabvoton controller from I want to get another one the one that came with my bike is restricted and I have no regen with the one I got if you could let me know I would really appreciate it. If you have a link to where you ordered it from that would help me out so much. Thanks for the video I think the problem your having has to do with the rim if it’s not true then it would start to wobble and the faster you go it just start to get worse because of it being unbalanced. I would bet money on that I sure hope you get that fixed. See if you can find a bike shop to help you out also check your spokes get a spoke wrench to check them with. I just got one off Amazon for 10 bucks it’s a motorcycle wrench with different sizes on it. Some of my spokes need tightening. That’s got to be your problem especially because it gets worse at higher speeds. Thanks for your time. Ride safe buddy.

Hall Test. This is the self learning feature of the Sabvoton. You connect phase and hall wires in any order (but professional will color match them from the motor to controller), then run test, and the controller will pair the motor to itself. After that if the motor runs backwards you just open the app and select “reverse” to make it run correct direction. The Hall phase shift will appear after the test. Not to be confused with commutation angle of 60 or 120.

@@Killer-wu9hk , to make any controller work, it needs battery power connected, the motor phase and hall sensor connectors connected, the throttle connected, and the ignition wire connected. From there you should be able to open the MQCON app and verify voltage settings match your battery. Then with the rear wheel off the ground you would run the hall test, and the motor will start moving slowly as it checks the relationship between the phases and the hall sensors. After it finishes, and you save it, the motor should run. Of the motor runs forward then its correct, if it runs backwards then in the app you can change the direction. You never need to change any phase wires or hall wires after the initial color matching of all 8 wires. Any mismatch will be fixed inside the controller.
