Troubleshooting
We fully understand your feelings when you meet a problem with the trike. Contacting us on the
website where you bought the t6-8rike and telling us your problem in detail with some pictures and
videos will be the fastest and easiest way to help you solve the problem. Please don't forget to
leave your order number to us for reference.
The following are some assist tips for electrical problems:
The display can not light up
Please fully charge the battery ( hours). The LED on the charger should be green color when the battery
is full charged.
If it still doesn’t work, please check the wires and battery, please make sure the connections are not
loose, and the battery installs in place, then please light up the display in the correct order (light up the
power button on the battery, press the “M” button, and hold 3 seconds).
If it still doesn’t work, we need to get a voltmeter, and do some testing:
First, please light up the power button, and test the battery output voltage (Figure 8-1). If the voltage is
“0”, it means there is something wrong with the battery output plug, cell, or fuse. Please take a picture
or a video to show your testing result, and then send it to us. The customer service department will
give you a solution. If the battery voltage is not “0”, but less than 42V, please full charge the battery
(6-8 hours), then test it again; if the battery voltage is between42-54v, but the display can not be light
up, it means the battery is in good condition, we need to test the other two plugs.
Second, please open the controller box, and find the power wire (black and red color) that connecting
the battery and controller (Figure. 8-2). Please test the power wire’s voltage. If it is “0”, it means the
power wire needs to replace, please take pictures, and send the pics to us. If the voltage is the same as
the battery, there's no problem with the power wire. We need to test the output voltage of the
controller. It is the plug that connects the controller and display. It has five wires on the plug, please
test the red and black wires (Figure. 8-3). If the voltage is “0”, it means the controller needs to be
replaced, please take some pictures and send them to us; if the voltage is the same as the battery, it
means the display needs to be replaced. Please picture the testing results and send them to us. It will
help us for solving your problem asap.

The throttle does not work
We mean the display can be lighted up, with no error codes, but the throttle does not work. The
brakes have two functions when you press the brake lever: 1. it will stop the trike 2. it will cut the
power of the motor.
First, please check the brake lever, and make sure the brake lever can hold or release fluently. If not,
maybe the brake cut the power. Please video your problem and send it to us. We will give you a
solution.
Second, please make sure the number behind “PAS” is bigger than “0”. If the number is “0”, it means
no throttle or no pedal assist. Please test the pedal assist mode (please lift the front wheel, then turn
the crank a whole cycle), and walk assist mode(press the “down” button and hold 3 seconds). If only
the throttle does not work, it means the throttle needs to be replaced. Please video your testing and
send the video to us. If none of the three modes works, we need to test the motor wire and brake
sensor.
Third, please find the plug on the motor wire (Figure. 9-1), the connection may loose. Please re-plug it,
restart the trike, and then test all three modes, if it still doesn’t work, we need to check the brake
sensor.
Fourth, please open the controller box (Figure. 9-2), and find the two plugs that connect the brake
levers and controller. It is the only two plugs that have two wires on each plug (Figure. 9-3). Please
disconnect them, then test all three modes again. If they work, it means the brake sensor is defective.
The brake wires need to be replaced. If it still doesn’t work, it means the controller needs to be
replaced. Please video your problem, and send the video to us.
If it still doesn’t work after replacing the brake wire or controller, please video how you do the
troubleshooting, and send the video to us.
