INTRODUCTION
Thank you for purchasing our bSeen product.
bSeen is an indicator light kit developed for electric scooters, electric
bicycles and any other vehicle that lacks of indicators, and light warning
systems.
Sold as a “do it yourself” kit, bSeen is a powerful and reliable system,
based on the latest technologies.
At the heart of the system, a micro-controller was programmed for the
most basic tasks, such as right and left turn, and other functions such as
hazard warning lights, horn and headlight control.
bSeen LED units are extremely bright, and can be seen during the day.
LED units are manufactured in-house and carefully inspected to ensure
their waterproof properties.
bSeen handlebar switch unit is easy to operate, with all controls you need
to control your indicator system.!

INSTALLATION
bSeen X e-bike was designed to be fitted on your e-bike, and it uses your
bike’s battery power to operate.
PROCEED WITH CAUTION AND READ CAREFULLY
The installation of the bSeen X kit requires electric skills, such as
soldering and stripping electrical wires.
If you’re not familiar with such proceedings, ask for support from your
bicycle dealer or from an automotive electrician expert.
Damage to the bSeen ECU, LED units and/or Handlebar Control Unit
due to faulty connections, short circuits or polarity inversions, will not be
covered by warranty.
Please keep in mind, modifications to your e-bike can void its warranty.
Make sure you read and understand your e-bike’ manufacturer warranty
terms, and proceed with bSeen’s kit installation with caution.

INSTALLATION - HANDLEBAR CONTROL UNIT
Remove your left or right handlebar grip, and once removed, install the
bSeen Handlebar Control Unit in place. Be sure to tighten the hexagonal
screw located at the back of the unit:
The Handlebar Control Unit is supplied with a 2 metres cable length and a
Higo connector. The cable runs along with the brake and gear line, to the
place where you decided to fit the ECU (bSeen Control Unit):
Tighten the hexagonal screw located on the back of the unit

INSTALLATION - REAR LED UNITS & CABLE MANAGEMENT
Rear LED units (indicators) can be fitted on both sides of the rear frame/
forks.
Each LED unit is supplied with a 3M VHB double tape pad, designed for
automotive industry and resistant to all kinds of weather conditions.
Find the best place to fit each indicator. These should be facing the traffic
behind your e-bike, so your turning intentions can be seen by other road
users.
Peel the double tape on the back of the LED, and stick the LED unit in
place. The bonding process will take up to 24 hours to complete. You can,
however, use the e-bike normally, after finishing your installation. This
won’t interfere with the bonding process.

Run the LED units’ cables through the e-bike’s frame to the place where
you decided to fit the ECU.
In the picture bellow, the cables are fixed with the same 3M VHB double
tape on the interior of the the chain stays, and then it was used cable ties
to secure the cable to through the rear brake line.

INSTALLATION - FRONT LED UNITS CABLE PLACEMENT
The front LED units are mounted on the front fork - one on each side of it.
As you did on the previous step for the rear LED units, peel the double
tape and stick the LED unit in place.
Run the LED units’ cables along the brake lines to the place where you will
be fitting the ECU, using cable ties to fix them along the line.

INSTALLATION - CONNECTIONS OVERLOOK
Once all LED units and handlebar switch cables are in place, these will
need to be connected to the ECU.
The Handlebar Control Unit cable has a fixed Higo connector at the end,
and the connection is made directly onto the ECU.
The LED units’ cables are supplied with 2 metres length, and these, if you
wish, can be cut to size (read “attention” box below).
Each LED unit cable is marked with a red sleeve, which indicates the LED’s
positive polarity.
!
ATTENTION
If you wish to cut any LED cable to size, make sure you mark the positive
polarity prior to the cut.
Inverting polarities won’t damage neither the LED unit, nor the ECU unit.
The result will be a non blinking LED unit, and the connection to the
ECU will need to be re-done.

The ECU for the e-bike was designed to fit anywhere on your e-bike’s
frame, and it’s basically half size of a credit card (check dimensions). We
recommend to do all connections and final tests, prior to its final fixing.
The ECU has connection points on two sides of its enclosure:

INSTALLATION - CONNECTIONS - LED UNITS
To connect your LED units’ cables to the ECU, start by stripping each LED
wire about 1 cm.
Your bSeen kit is supplied with a special heat shrink sleeve, with internal
solder (silver ring), and a waterproof seal on each end on the sleeve (Red
rings).
Once you stripped all LED units’ wires, slide the heat shrink sleeve through
each one as shown bellow:

Next, join the LED wire with the correspondent ECU’s wire and firmly twist
them both:
Slide the heat shrink sleeve and make sure the solder ring (silver) is in the
middle of the exposed copper. Also, make sure the red rings placed over
the wire’s rubber insulation - the red rings are the water seal:
ATTENTION
Double check the cables’ polarities.

While holding the heat shrink, start by heating the solder, which will start to
melt at around 130 degrees. Use a heat gun or - only as last resource - a
normal lighter.
Once the solder is melted, and spread through the copper, heat the rest of
the sleeve, including the red rings, until you get a fully sealed connection.
Allow the heat shrink to cool down, and repeat the process for all LED
wires.

INSTALLATION - CONNECTIONS - HANDLEBAR CONTROL UNIT
The connection to the Handlebar Control Unit is made via a 6 pin
connector.
Inspect the interior of the connectors before plug them together. The pins
inside the male connector are fragile and can bend if both connectors are
offset.
There’s also an arrow icon on each connector’s enclosure. Aligning both
arrows will ensure you the connection can be made.
Once both arrows are aligned, apply some pressure to secure the
connection.
You might be left with some extra handlebar control cable. This leftover
can be coiled and you can use cable ties to avoid the cable hanging.

INSTALLATION - CONNECTIONS - BATTERY
bSeen can be plugged directly onto the e-bike’s battery output voltage.
bSeen’s voltage regulator, can support input voltages from 18V to 78V
and it’s electronically protected against short circuits, overloads and
overheat.
On this example we used a Bosch battery system, using the battery’s
charger port to feed bSeen’s ECU. Use bSeen’s loose power cable,
supplied with the kit.

ATTENTION - DISCLOSURE
Before proceed with the steps below, please make sure you have the
right credentials or skills to handle with electric/electronic circuitries.
The process shown on this manual’s section, it’s only an example on how
bSeen ECU can be plugged onto an e-bike’s battery system, and does
not consist any standard practice. Battery systems differ from from e-
bike to e-bike, and your battery pack can be different from the one
shown here.
The process described below involves a professional soldering method,
and if you’re familiar with it, please ask support from your e-bike dealer
or an automotive electrician expert.
bSeen, will not be liable for any damage caused to your vehicle, and all
connections are made at owners’ responsibility.
ATTENTION
Remove the battery from your e-bike before proceed.
