IMPORTANT SAFETY INFORMATION
• Do not operate this e-Bike without carefully reading the manual and
understanding how to operate the e-Bike.
• Wear your helmet, gloves and other protective gear before riding
to protect yourself from injury in case of an accident. We recommend
wearing bright or reflective clothes when riding at night.
• Observe rules and regulations when using this e-Bike. Passengers
should not be carried. When riding in rainy, snowy or slippery
conditions reduce your speed and increase the distance between
yourself and other vehicles.
• Your insurance policies may not provide coverage for accidents
involving the use of this e-Bike; to determine if coverage is provided
you should contact your insurance agent.
• Charge the battery in a dry place and ensure there is adequate
ventilation.
Neither the battery nor the charger should be covered during the
charging process. A lot of heat can be created during the charging
process and this has to be able to escape. Otherwise this could
lead to a danger of overheating or a possible hazard. We recommend
charging under supervision or with the user present. Only use an
Erikson charger to charge the battery.
• If planning to store the battery for a long time without using it, make
sure to charge it before storing. The battery is best preserved in
a cool and dry environment. It also needs to be charged once a month
if planning to store for several months.
• Lock then remove the key before riding. Otherwise, you may injure
yourself on the protruding key, lose or damage the key, or the battery
could become loose and fall out. This could result in accidents and
injury.
• The e-Bike should not be left out in the rain for a long time or
submerged because if water enters into the controller and motor
wheel, it may cause short circuit and damage the electrical
components.
• Keep appropriate air pressure inside the tires, so as to avoid
increased friction when riding, as low air pressure may easily wear
the tires and deform the rim.
• When riding with high speed or downhill, use the rear brake to avoid
the center of gravity from moving ahead, as using the front brake may
result in a shift in the center of gravity and may be dangerous.
• Do not alter any components on the e-Bike. Any changes to
the e-Bike not approved by Erikson will nullify the warranty
on the manufacturer’s side and may result to damage or injury.

OPERATION AND ADJUSTMENT
INSTALLING THE BATTERY
To insert the battery turn and hold the locking key counter-clockwise
and slide the battery securely into position. Release the key, ensure that
the battery is locked in place, and remove the key.
REMOVING THE BATTERY
To remove the battery, first turn and hold the locking key counter-
clockwise, then slide the battery out of the holder. Release and remove
the key.
SHIFTER
Bridge26 e-Bike has gears, which consists of:
• A rear sprocket cluster, called a freewheel or cog set
• A rear derailleur
• One shifter
• One control cable
• One front sprocket (called a chaining)
• A drive chain

7
There are many different types of shifter mechanisms, each preferred
for specific applications because of its ergonomic, performance and
price characteristics. A down-shift is a shift to a lower or slower gear,
one which is easier to pedal. An up-shift is a shift to a higher or faster
gear, one which is harder to pedal. For example, you can down-shift to a
lower gear to make pedaling easier on a hill. On the other hand, you may
up-shift to a higher gear when you wish to go faster. Whether up shifting
or down-shifting, the derailleur system requires that the Drive Chain
be moving forward and be under at least some tension. A derailleur will
shift only if you are pedaling forward.
Caution: Never move the shifter while pedaling backward. Do not
pedal backwards after moving the shifter. Both of these actions could
jam the chain and cause serious damage to the e-Bike.
POWER INDICATOR
When the throttle or sensor is engaged (Powering the motor) and the
bicycle is in motion, the LED on the battery gauge (on the throttle or
separate unit) indicates the instantaneous line voltage as measured at
the battery terminals - not the available energy in the battery pack. The
line voltage will max out from a dead stop, or going up a steep hill, the
motor will be under a high load and may show a reduced number of LED
or show the “Yellow” or even ”Red” LED.
When the throttle is disengaged (i.e. no power to the motor due to the
bicycle being Stationary or coasting) LED on the throttle will indicate
the voltage of the battery pack. The voltage of the battery pack will rise
when no load is on the motor. The best indication of how much battery
life is remaining is to check the throttle LED, after reaching cruising
speed, on a flat straight road as this will allow the battery voltage to
stabilize and give a much more accurate reading.
CHARGING
The battery should be charged before it is used for the first time. Please
only use the charger designated by Erikson for charging; otherwise it
might damage the battery, and may even lead to fire and other hazards.
Warranty will be voided if a charger other than the one designated by
Erikson is used.
1) Check carefully whether the rated input voltage of the charger is
consistent with the voltage of the power grid.

8
2) The battery can also be taken out of the bike to be charged
indoors and at other appropriate places.
3) First connect the output plug of the charger to the charging jack
of the battery properly, and then connect the input plug of the
charger to the AC power supply.
4) At this time, the power indicator light on the battery and the
charge indicator light of the charger should light up, indicating
that the charger has been connected.
5) Fully charging an “empty” battery takes 3-4 hours. When the
charge indicator light on the charger turns from red to green, the
battery has been fully charged.
6) After charging, pull out the AC power plug, and then pull out the
plug connected with the battery.
SAFETY CONCERNS
1) The battery should be charged in an open environment, staying
away from high temperature, high humidity and fire, because the
battery and the charger are electronic products, high temperature
and humidity will corrode electronic components, resulting in
some harmful gases and soot, and even a possible explosion.
2) Do not overcharge the battery. An excessive charging time will
lead to shortened life expectancy of the battery.
3) After the battery is fully charged, the power supply should be
pulled out as soon as possible, and at the same time, the battery
is disconnected from the charger.
BATTERY MAINTENANCE
1) You can achieve the best possible performance and lifespan of
your battery by charging on a regular basis and using it within the
recommended temperature range. The battery has almost no
memory effect thanks to the Li-ion technology.
2) Leaving a fully discharged battery for a long time will lead to
permanent loss of LEDs. Please recharge an empty battery as
soon as you have a chance to. If storing the battery for an
extended period, we recommend recharging at least up to
¾ (4 LEDs) at least every 30 days to avoid damage to the
battery. A dead battery due to neglect is not a warranty claim.
3) If your e -Bike does not move for a 30 minutes period, the BMS
will switch the battery power off. In order to continue riding with
assist, you have to switch the battery on again.

9
4) Every battery with Li-ion technology is subject to an unstoppable
chemical aging process. Provided the e-Bike has been used
properly, remaining capacity of 70% will remain after 500
charging cycles.
5) Please follow municipal regulations as to how to discard the
battery appropriately, so as to avoid environmental pollution.
6) Recommended temperature ranges:
a) Charging / Discharging: 0-45 Cº, 32-113Fº
b) Storage: <35Cº/95Fº
INSTALLATION OF THE FRONT WHEEL

USE AND MAINTENANCE
INTENDED USE
This e-Bike is intended for transporting one person at a time. Fit your
e-Bike with suitable equipment if you would like to transport luggage.
Ensure that you do not exceed the maximum permissible load (rider
+ luggage) of 265 lb (120 kg). The manufacturer and dealer do not
assume any liability for activities above and beyond the intended use.
This particularly applies for not adhering to safety advice and damage
resulting from this, for instance: aggressive off-road use, carrying
excess weight or making improper repairs to defects. The e-Bike is not
generally designed to withstand extreme stress, such as riding down
steps or over jumps.
BEFORE THE FIRST RIDE
1) Please fully charge the battery before the first use.
2) Please ensure that your e-Bike is ready for use and is adjusted to
your body, including:
a) Setting the position and fixture of the seat and handlebar
b) Checking the assembly and settings of the brakes
c) Securing the wheels into the frame and fork
d) Checking the tire pressure
e) Checking that battery is properly secured
3) Ensure that you know which lever operates which brake (right/left).
4) Before you switch the system on, ensure that the battery is
securely locked to the frame.
5) The effectiveness of brakes can be different in wet conditions or
on slippery surfaces. Please take into account the possibility of
longer braking distances and slippery surfaces when riding.
6) Practice operating and riding your e-Bike in a quiet and safe place.
7) Ensure that the wheels are securely fastened in the frame and
fork. Check that the wheels and thru axles as well as all important
nuts and bolts are secure.
8) Push the wheels forward with the brakes pulled. The back brake
should completely prevent the back wheel from moving, while the
front brake should lift the back wheel off the ground with its
braking effect. The e-Bike’s steering should not rattle under
braking or exhibit any play.

12
9) Check the air pressure in the tires. You will find instructions as to
the correct tire pressures on the sides of the tires. Please adhere
to the required minimum and maximum pressure. As a general
rule of thumb, e.g. on a ride, you can check the tire pressure as
follows: If you place your thumb on a pumped-up tire, you should
not be able to significantly change its shape by applying pressure.
10) Check the tires and rims. Scan them for any damage, cracks or
deformations, as well as embedded particles, e.g. shards of glass
or sharp stones.
11) If you should find any cuts, rips or holes in the tires, please refrain
from riding. First have your e-Bike checked over by a qualified
e-Bike mechanic and have any required tire service completed.
BEFORE EACH RIDE
Before each ride, please check that:
1) The brakes are working safely and are properly secured.
2) The tires are free of foreign objects and damage, and the wheels
run true.
3) The battery is properly secured.
4) The tires have sufficient pressure and tread depth.
5) All bolts and nuts are tight.
6) Check that all quick releases are still correctly secured.
7) The frame and fork are not damaged.
8) The handlebar and stem are correctly and securely fastened as
well as set up in the correct position.
9) The seat post and seat are secure and in the correct position. Try
turning the seat or tipping it upwards or downwards. It should not
