Q: The 2000w bike conversion kit<\/a> arrived safe and sound. I wonder if you would explain to me some of the wire connectors are for. What I should set
\n-U02 Power Watt Max \u00a01000W default or 2000W hub motor<\/a>
\n-U03 What is power gear? Saved, Gear 1,2\u2026
\n-P07 Speed magnet number?24 ,36,48?
\n-P14 Current Limit? 30A-40A?
\nAfter I install the brake Cut off sensor I have E2 error what wrong
\nWhat are 2 blue wire connector for? 2 \u00a05 Pin connector\u00a0 at motor I use either one They work fine So what is the extra 5 pin connector for?
\nPlease help me to make it work right.
\nThe speed I got 86 kmh on 48V 15ah battery<\/p>\n

A: U02 – You can set it as your hub motor power\u00a0 (Don’t set)
\nU03 – Don’t set
\nP07 — 46
\nP14 — You can set 30A or 40A.\u00a0 (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.
\n\u00a0
\nE2 – Your brake lever or sensor is braking. (Cut off motor power, at this time, motor can’t work)
\n\u00a0
\nTwo blue wires are used for:\u00a0 look for phase wire, look for correct working way.\u00a0 If can’t work. Connect these blue wires together. Controller can look for right working way by itself.
\n\u00a0
\n5 pin extra — 2 sets of 5 pin extra are the same.\u00a0 They are connected to 2 sets of hall sensors. If one hall is broken,motor can’t work.\u00a0
\nJust use the other 5 pin plug then can solve motor hall issue.<\/p>\n

Q\uff1aWould you help me with the E7 error code after 2 blue wire connected
\nIs 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.
\nSo what now?
\nThe 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
\nwhen I connect it with my e bike rear light ,and there are 2 wires (red+white) from display What are they for?
\nWould you help me with bike conversion kit. If I succeed to upgrade my e bike I may do upgrade for my friends.
\nI will properly need you with more orders.
\nIt worked now. THANKS<\/p>\n","protected":false},"excerpt":{"rendered":"
