The Throttle Does Not Work
This situation applies if the display powers up and there is no error code, and the PAS level is not set to 0
but the throttle does not work.
I
f the number for the PAS system is 0, it means no throttle or no pedal
assistance will be provided.
You can test the PAS mode by lifting up the rear wheel and then turning the crank one whole cycle. This
is a job that should be performed by two people. You can also test the power walk assist mode by
pressing the down button and holding for three seconds.
The brakes on ebikes have two functions when you press the brake lever. One, it will stop the ebike.
Two, it will cut power off to the motor. If the electronic system sees either of the brakes as being
engaged, the power to the motor will be cut and neither throttle nor pedal power assist will be
provided.
To check for brake power cut off issues, make sure that the brake lever can be held or released with
ease. If not, maybe the brake is cutting the power to the motor. Please take a video of your test and
send it to us. We will look to determine how best to proceed.
If PAS is not set to 0 and brakes seem free and not caught or seized in any way the next thing to look at
would be wiring and connections. Find the plug on motor wire (Figure 8.1). It is possible that the
connection has become loose. Try to replug it and then restart the ebike. If all wires are intact and all
connections secure the next thing to look at would be the brake sensor. Open the controller box
(Figure 8.2). Find the two plugs that connect the brake levers and controllers. It is the only two plugs
that have two wires on each plug (Figure 8.3). Please disconnect them, then test all three modes again,
if they work, it means the brake sensor is defective and the brake wires need to be replaced. If still not
working, it likely means that the controller needs to be replaced, please video your issue and your
testing, and send the video to us.
