What's makes bikes better than ordinary bikes? It's commonly the pedal assist system (PAS), but with our mid-drive line, let's just say we've gone a bit further and included a throttle to tie it all together.
We at CYC pride ourselves in having a fully customizable e-bike experience; from adjusting the reaction of the throttle for every gear, mode, and even fine-tuning each type of reaction users see fit.
Though - you will need to know what to do to take full advantage of a customizable system. The descriptions below are exactly how you will them in our CYC Motor Mobile app for BAC controllers.
In the app, under "Settings", you'll see the "Throttle" tab. After tapping it, there comes two main tabs; "Throttle Settings" and "Throttle Ramp Times". The former is your general settings, while the latter parameter are the settings that affect how fast your throttle will react.
Throttle Settings
Throttle Settings come with five different parameters; four of which are adjustable.
Throttle Voltage Reading
The first parameter is your Throttle Voltage Reading, which is your throttle's voltage reading. This value will be just below 1 out of the box - provided that you are using a throttle supplied by us. It could be different for throttles supplied elsewhere.
Throttle Full Voltage
Next, is the Throttle Full Voltage. This is the output of the throttle when fully opened and is pre-set for you when purchased. You do not need to change this at all with CYC supplied throttles.
Throttle Off Voltage
The Throttle Off Voltage value should be the same as the Throttle Voltage Reading when the throttle is closed and tells us the output of the throttle when it is not active.
Throttle Fault Range
Moving on, you get the Throttle Fault Range. This is the amount the throttle can move up and down without activating. In other words, when you are driving around on a bumpy road and the throttle moves slightly, it will not drastically affect your speed. Technically, within the 0.2V range, the output will remain constant. Only when moving the throttle more than 0.2V, will the response of the motor change.
Throttle Deadband Threshold
The Throttle Deadband Threshold pertains to opening the throttle when it’s completely closed. This is the amount the throttle can be moved from the zero position without generating a response from the motor. If this value is set
lower, your throttle will engage quicker and vice versa.
It’s like the dead-spot on a motorcycle throttle, where the babble is not in tension yet to rev the motor.
Throttles from Different Suppliers
What if you have a throttle from a different supplier? If this is the case, then your Throttle Full & Off Voltage values needs to be checked and entered manually. The Throttle Full Voltage can be obtained by making sure the bike is in Assist Level 0, so the motor will not be activated when the throttle is pressed down. Then, when fully opening the throttle, the Throttle Full Voltage can be read from the Throttle Voltage Reading above. Enter that value into the Throttle Full Voltage parameter.
The same goes for the Throttle Off Voltage. Enter the value that is read from the Throttle Voltage Reading, but this time when the throttle is in a closed position i.e., not activated at all. Your Throttle Off Voltage and your Throttle Voltage Reading will then be the same when the throttle is completely closed.
Throttle Ramp Times
The Throttle Ramp Times affect the response times when opening and closing the throttle.
Positive Motoring Torque Ramp
The Positive Motoring Torque Ramp is the time it takes to achieve the required input. Say, if you open the throttle fully, it will take 250ms before the motor gives you full power. It will gradually ramp up to full power within the set time. We recommend not to set this below 150ms.
Negative Motoring Torque Ramp
Then, the Negative Motoring Torque Ramp is the time it takes for the motor to stop responding after the throttle is closed. This value is usually set low to stop any motor response after the throttle is closed as soon as possible. We do not recommend setting this value higher.
Common Questions About the Throttle Settings
Q: Which parameters can adjust the sensitivity of my throttle?
A: The Throttle Fault Range, Deadband Threshold, Positive and Negative Motoring Torque Ramp are the parameters that set the sensitivity and responsiveness of your throttle.
Q: How can I turn my throttle off?
A: The second parameter under Pedal Assist settings, is called “Control Command Source”. Here, you can select whether you want to activate your throttle.
