They are 4.12 HW version. I bought 2x of them from a PCBA house. PM me with your phone number and we can work something out

Sure! If you are local im willing to part out some things. PM your phone number and we can get in touch. Thanks.

Hi, Im selling quite a large lot of hub motors motors and ebike parts. I bought a lot awhile back to test some custom motor controllers and embedded electronics I was developing. After I finished motor characterization I no longer need them. I want to sell everything in one go but please ask...

MXUS 5K Hub motor on 26inch DH rim ($500) Adaptto MAX E Controller with Display ($650) no charge coil - SOLD 20s 10ah Custom Lipo Battery Pack ($450) Custom A123 24s 8.8ah 26650 Battery ($650) Eltek IP67 3.3KW charger with can controller configured for 20s lipo 75-125v ($700) All prices are...

I just finished the bike up! I'm having some issues with the Adaptto BMS since there are some I2C errors between master and slave BMS modules. I think something is wrong with one of the TI 4s BMS ICs but I haven't given it a good look yet. I want to design a better BMS down the road and was...

Just finished the bike today and took the first test ride around. Charging is working great. I programmed a spare C2000 launchpad as a CAN controller because I had one on hand and its works great. Next up is to figure out the J1772 handshake and I'm ready to roll. For now, I will just use the...

Here is a bit more progress on the bike. Working away on the battery and charger system. Just ordered some CANbed boards in the mail since they are tiny and cheap ($20 a pop on mouser with a SAM32 based mcu!)

Hi guys! I decide to convert a Norco A-Line into an electric bike. The plan is to use an MXUS 5K Hub motor and Adaptto Max-E controller with a 20s 10ah zippy compact lipo pack. I'm going to use either a C2000 or Teensy 4.1 for thermal management (trigger fans from thermistor setpoints) and CAN...

Ive been using the 5k Turbo with a Adaptto MAX-E and its been a really great motor. I bought it from alibaba for 400 shipped with a laced rim too! Worth every cent. I would highly recommend this motor. so far its taken me up to 48mph on the 4T variant without drawing more than 6.8kw for the...

Yeah, its the 4T version of the motor. The battery cells haven't been used in many years so it's going to take a few cycles to wear it back in. I hit 48mph the other day this thing is seriously fast, to say the least (Currently limited to 40 battery amps right now). I think speeds of 65+ are...

After saving up for a LONG time, I finally was able to get the funds together for my dream bike conversion, and boy is it fun. I got the 4T MXUS 5k moto from Alibaba, the Adaptto MAX-E used off of an NYX bike and the A123 from a local EV conversion shop that didn't know how much there were worth...

I disagree since Torque generated = (60 * K * I * flux)/ 2pi where K is the armature torque constant and I is the current. The torque generated is directly proportionate to the current being fed into them.

Yeah its a current ramping limit. Basically a torque limiter

I put a torque curve on the motor controller for that reason. It ramps up the power from 10% to 100% in a given time independent from the position of the throttle.

They arent 18650s they are large Caps I think you are talking about the VESC noise protection but im not sure. I will post videos soon
