Q: The 2000w bike conversion kit arrived safe and sound. I wonder if you would explain to me some of the wire connectors are for. What I should set
-U02 Power Watt Max 1000W default or 2000W hub motor
-U03 What is power gear? Saved, Gear 1,2…
-P07 Speed magnet number?24 ,36,48?
-P14 Current Limit? 30A-40A?
After I install the brake Cut off sensor I have E2 error what wrong
What are 2 blue wire connector for? 2 5 Pin connector at motor I use either one They work fine So what is the extra 5 pin connector for?
Please help me to make it work right.
The speed I got 86 kmh on 48V 15ah battery
A: U02 – You can set it as your hub motor power (Don’t set)
U03 – Don’t set
P07 — 46
P14 — You can set 30A or 40A. (Less current is bigger for controller) You can set 30A first, then ride or uphill, if good. That’s good. If not good for uphill, set it to 40A.
E2 – Your brake lever or sensor is braking. (Cut off motor power, at this time, motor can’t work)
Two blue wires are used for: look for phase wire, look for correct working way. If can’t work. Connect these blue wires together. Controller can look for right working way by itself.
5 pin extra — 2 sets of 5 pin extra are the same. They are connected to 2 sets of hall sensors. If one hall is broken,motor can’t work.
Just use the other 5 pin plug then can solve motor hall issue.
Q：Would you help me with the E7 error code after 2 blue wire connected
Is the hub motor failed? After connect 2 blue wire together I got E7 and motor stopped working. I worked fine I got 90kmh after I follow your instruction.
So what now?
The hub Motor and the speed controller work fine so far just a minor issue with the light wire (red+black)from the controller that does not work
when I connect it with my e bike rear light ,and there are 2 wires (red+white) from display What are they for?
Would you help me with bike conversion kit. If I succeed to upgrade my e bike I may do upgrade for my friends.
I will properly need you with more orders.
It worked now. THANKS
