Excessive electric current is detected inside the controller, and a
protection mechanism is implemented.
Check whether the three-phase power cable terminal connector is
short-circuited.
If there is no short-circuit, restart it.
If this state still occurs, means the internal power device of the
controller is damaged.
The motor's three-phase power cable has fallen off, loosened, or
the motor has stopped operating for more than 2 seconds, or the
load is too heavy and the motor cannot operate normally, or the
power input isn’t connect properly.
If this state still occurs after restarting, it is the reason for the poor
connection of the three-phase wires of the motor.
The voltage of battery is excessively low; the battery is under
voltage protection.
This error code can detect whether the brake lever is damaged
under normal conditions.
The error code should disappear after the brake is released.
The power system detects whether the torque signal is faulty on the
system.
The electric circuit system detects whether the internal electric
current loop components of the controller are damaged, or the 5V
loop is short-circuited, and if there is, the status will be displayed.
The battery voltage needs to be checked at all times when the
circuit system is operating.
If the battery voltage is >43.5V, it means that high voltage
protection occurs, or the cable sequence of the sensor is
connected incorrectly, and the system will stop operating and
display this status.
Final Check
Folding & Unfolding
After completion of assembly, please perform a final check and make sure that:
1. Every bolt and screw is tightened properly.
2. Tires are inflated to the recommended tire pressure.
3. Brakes are functioning properly.
Note:
1. Fold your DAHON E-bike according to the manual.
2. When folding and unfolding please take care to check that
the internal cables are not caught. Should this occur, simply
push the two cables back inside the frame.
Folding:
(1) Adjust seatpost and crank: loosen seatpost clamp lever, lower the seatpost,
then lock the seatpost clamp, and adjust the left crank to 9 o'clock position.
(2) Folding the handlebar assembly: loosen the safety catch on the stem, pull the
stem hinge handle down, and then fold the stem down to align the whole
handlebar parallel to the front wheel.
(3) Folding the frame: open the frame safety hook, open the frame hinge lever, put
your knees against the frame folding joint, and bring the front and rear wheels
of the pedelec backward to make the front and rear wheels merge and align
parallel.
(4) Please be aware: Do not fold the bike when the battery is removed for charging.
Unfolding:
Reverse the operation sequence from back to front (expand the frame → lift the
folding stem→ raise the seatpost to an appropriate height → tighten relevant
latches and safety hook) to achieve full unfolding.
Lower the seatpost Fold down the stem Fold the frame in half

Handlebar adjustment
Seatpost and saddle adjustment
Adjustment of the brakes and derailleur
(1) Loosen the handlepost quick release and adjust the handlepost to an
appropriate height (the safety scale line must not be exposed outside the
tube), and then lock the handle.
(2) Loosen the stem handle and adjust the handlebar to a proper angle.
(1) Loosen the seatpost clamp and adjust the seatpost to an appropriate height
(the safety line should not be visible outside of the pedelec )
(2) Loosen the locking bolt at the bottom of the saddle, adjust the saddle to an
appropriate angle and tighten the bolt (recommended force moment is 18N•m).
(1) Brake adjustment:
Safetyline
Safe position
In the case of improper adjustment of brakes, or serious wearing of brake
pads, it will pose a threat to the safety of riders. Please adjust or replace
relevant accessories on time. The brake on the wheel rim of a pedelec
functions via friction between the brake surfaces. The brake structure
depends on the friction between the brake pad and the wheel rim or disc to
ensure maximum friction. Please keep rims or discs and brake pads clean,
free of dirt, lubricants, waxes or polishing agents that may reduce the
efficiency of friction. The brake is designed to control the speed of the bike,
not just to stop it. Brake pads are fragile parts. Please adjust the brake and
brake pads properly according to wear and conditions.
