E-Brake Sensors Install
This kit comes standard with E-Brake
Sensors which are a nifty little
invention that enables you to use your
existing brake levers. This solves a
common issue from previous systems
that required the replacement of
the brake levers which is more time
consuming and also problematic if you
have hydraulic brakes or integrated
gear shifters.
In this series of photos, we have
shown the installation of the magnetic
square and the sensor on the top
surface of the brake lever. This is
purely for visualisation purposes. The
sensors/magnets can also be installed
underneath the brake levers so they
are hidden, making for a sleeker look.
The magnetic square and the sensor
should be installed so that when the
brake lever is realeased, they contact
each other.
When you pull on the lever to brake,
the sensor will register the proximity
change and activate the e-brake cut
off. This means that when you use
your brakes, the pedal assistance will
stop.
Cable ties can be added to the sensor
for added rigidity.
If you prefer not to add the e-brake
sensors, the system will still
function without them. For throttle
installations, e-brake cut off is not
necessary. For installations with pedal
assist, it is highly recommended (and
mandatory in some states).
Normally this step would involve the removal of
the crank which can be quite complicated. Thanks
to Dillenger’s innovative RPAS, this step is now a
breeze!
To begin, have a look at the black plastic magnet
wheel and the way the two halves join together.
When you snap them together on the crank axle,
(on your bike) you will then need to fit the steel
circlip around the outside groove.
The purpose of the pedal assist sensor is to
generate a signal from the rotation of the crank
that the controller processes to know that you’re
pedaling and want some power!
How does this work? Magnets on the disk
generate a changing magnetic field or a ‘hall
effect’ and this is picked up by the hall effect
sensor which transmits a signal to the controller.
The pedal assist is the primary function of
an electric bike and the level of assistance is
adjustable on the handlebar LCD.
1. The sensor will need to line up very closely
(under 5mm) to the RPAS disk.
2. Be sure to have the “working side” text facing
the sensor. The RPAS is directional, so when you
pedal backwards, the motor won’t engage (that
would be dangerous and annoying!)
3. With the two halves of the disk mated together
you can mount the silver circlip onto the disk,
without jamming your fingers in the process
(ideal, but not always possible).
4. When fitting the hall effect cadence sensor,
the adhesive section is only there to hold it in
place while you secure the sensor with cable ties
provided.
