Hello everyone- I’ll try and be brief! I bought two bikes, only a month old on ebay; so secondhand.
My bike is a samebike g-two- cheap but great fun to use. Also I have an identical one from ‘Dohiker’, the only reason I mention this is because it has helped to compare with the testing of the broken bike. The story so far, about a month ago I had a message on the display ‘E07’ which means a motor issue.
I took the motor apart and found there was a little bit of water in the motor chamber. I tested the hall sensors and found that middle sensor ( which is white as opposed to the two outer ones that are black) was giving an erroneous reading – it was constantly reading about 2.75v while switched on and manually turning the motor. The other two are fluctuating between 0v and about 4.9v as the motor is turned. As you will see from the photo all sensors are adjacent to red magnet at the same time, and red at the same time.
I was able to test the working bike without stripping to the motor; I found two hall sensors are generally 4.9v while the one is 0v , and as the one rises to 4.9v the other two drop to 0v.
After some help from this forum, I replaced the white hall sensor with a ss41 .( Electric Effect Hall Sensor Linear Bipolor) - this didn’t work.
After more help, I replaced it with a ss441a. (HONEYWELL S&C SS441A SENSOR, HALL EFFECT, 70G, UNIPOLAR) the idea being, that this would give the opposite voltage to the others.
I have tried contacting samebike- though my suspicion is they only badge the bikes, and a third party factory manufacture them, and gearbest, who sell many of the samebike range. All I want to know is what is the type of hall sensor so I can replace it. But all of the companies want an order number which I have not got - I have tried to contact the seller for this information , but he hasn’t replied to me. I think it’s only responsible for them to help otherwise there’s another 20kg of scap metal.
So that’s all I need help on really- what is the model of this hall sensor, or what can I try next. The motor has this code printed on it: sw-py 36v14"250d. I can’t find a replacement motor either; though I am confident the right hall sensor would fix it. Any advice would be so welcome, thanks in advance.
