Video instructions for using RFID cards and Dat Bike App
Each Quantum vehicle comes with 2 RFID tags by default.
In case you lose your card, you need to contact Dat Bike to be provided with a new card. The procedure below describes opening a vehicle using an RFID tag.
Place the RFID card in the card swipe position on the vehicle to turn off the vehicle.
To turn off the vehicle in case the RFID tag is not needed, follow the procedure below.
This function operates when the vehicle stops completely and the speed reaches 0 km/h.
Follow the process below to connect the app to the vehicle.

Once the phone is connected to the car and within Bluetooth range, if you want to turn on the car, just press the multi-function switch.
Turning the electric throttle in direction (A) will supply energy to the electric motor to move the vehicle forward when the vehicle is in D or S mode and backward when the vehicle is in R mode. Energy supplied to the electric motor is proportional proportional to the angle of turning the electric throttle (the electric throttle has a built-in initial delay to prevent the throttle from being too sensitive, causing danger to the user, increasing vehicle safety).
Turn the electric throttle in direction (B) to reduce power to the electric motor. The electric throttle is released to its original state, the engine will not consume energy, at that time the vehicle continues to slow down due to inertia and the effect of
of the engine brake.
Quantum is equipped with a handbrake like other two-wheeled vehicles. When using the handbrake, the engine will automatically shut off to ensure safety. When you want to continue moving, just release the handbrake completely and turn the throttle back on.
The engine brake on the Quantum is integrated into the electric throttle. The grip of the engine brake is proportional to the angle of releasing the electric throttle (the more you release the throttle, the stronger the vehicle grips).
This special feature also helps recharge the battery each time you release the gas (about 10%) to help increase travel distance. In addition, the lifespan of the vehicle's brake pads is also increased because they are used less.
Engine braking only works when the vehicle is in D and S modes.
