Bike Assembly:
Tools Required: 4mm and 5mm Allen keys, 15mm spanner
›Remove all packaging carefully: and select a good area to
assemble the bike. Preferably on a non abrasive surface so you
don’t damage the bike.
›Easier with two people: Have someone hold the bike
upright for you. Then remove the bolt on the arch of the
front suspension fork using the 5mm Allen key.
›Front Light and Front Mudguard: To fit the front light and
mudguard align the holes with the top of the front suspension
hole. Insert the Allen key bolt and loosely tighten (don’t fully
tighten yet). Take the bolts from the side of the forks out, place
the support arms over the holes and replace the bolts to
secure the mudguard in place. Once complete, tighten bolts
fully.
›Handle bars: Fold up the handle bar and lock off lever.
›Front wheel: Place bike in a bike maintenance stand or turn up
side down so the bike is standing on the handlebars and saddle
but again try to do this on a non abrasive surface to avoid
damage. (remove battery first in order to lighten and make it
easier to maneuver the bike) Once in position take the front
wheel and the quick release skewer/axle bolt. Undo the plastic
end cap and take off one spring (leaving one spring on). Slide
the bolt through the Centre of the front wheel until it comes
out the other side, then place the spring back on first (small
end first) followed by the plastic end cap and loosely tighten.
Pick the wheel up and slide into the slots provided on the front
fork and push downwards until it stops. Once aligned you can
tighten up the skewer bolt. (lever should point upward when
fitted correctly)
›Disc brake: If not already correct adjust brake by releasing
brake cable with 5mm Allen key then adjust accordingly and
re-tighten. Spin the wheel to make sure it spin freely. You
can make minor adjustments by turning the plastic screw
located on the brake cable near the brake caliper and with a
5mm Allen key on the opposite side.
›Pedals: Locate pedals, separate left and right pedals indicated by
L / R print on threaded end of the pedal. Screw in each pedal in
to the crank arms with your fingers ensuring not to cross thread
them. Once located correctly, tighten with 15mm spanner.
Note: Your wheel should fully stop once the brake lever
is depressed halfway. If it does not stop, re-adjust them
accordingly.
Getting Started and how to use your power assistance:
Once your bike has been safety checked and is ready to ride the
next step is to turn on the electric.
Press the power button on the LED display on the handlebars. In
doing this the display should light up with red LED lights.
Once turned on the display will indicate battery life and it will
automatically select the lowest level of pedal assist. This will be
indicated by one red LED light nearest the minus sign of the
assist part of the display.
At this point if you start to ride the bike the PAS assistance will
automatically kick in and assist you whist pedaling. (Tip: stay
on the lowest level until you become confident enough to
increase the power) You can increase the level of assistance
simply by pressing the + button, this will be indicated by the
LED light moving closer to the + sign. You can repeat this until
you reach maximum assistance. (15.5 M.P.H) To come back down
the assistance levels simply press the - button. IMPORTANT:
Please be aware that the assistance is also sensitive to how fast
you pedal and will only give you maximum assist when you are
pedaling relatively fast. (this applies in most levels selected)
To turn off the assistance so you are only using manual pedaling
either press the power button or move down through the assist
modes with the - button until the LED no longer is lit up.
On the right hand side of the handlebars you will find (if fitted)
a half twist grip throttle. When the bike is turned on, the throttle
is active and operates independently of pedaling, a bit like a
moped. (no requirement to pedal) Please note the red isolation
button also needs to be in the depressed position for the
throttle to be on.
Simply twist the half grip throttle and it will propel the bike. It is
limited though to what level of assistance you have selected on
the PAS. (remember using the throttle will use more battery life
up quicker).
Turining the lights On/Off
To turn the lights on/off simply hold down the + button for a
few seconds.
IMPORTANT: When using the throttle try to avoid hill starts
and only use pedaling when the bike seems under strain to
avoid motor burnout. In not doing this it can also void your
warranty.

Battery Charging & Removal
To charge the battery this can either be done in situ or via removing the battery first. The charge point is situated on the right-hand
side of the battery. Turn on the charger first prior to plugging it in to the battery (the charger should indicate a green light). When
plugging the charger in to the charge point the light will turn from green to red to indicate it is charging. It will then change from
red to green to indicate when it is charged. (you can then remove the charger)
Step 1
If charging in situ simply lift silicone cover located on the side of the bike frame and insert the charger.
Folding & Unfolding:
Step 1
Locate the lever
halfway down the
handle bar stem.
Step 2
Lift latch first
then fold down
lever and and the
handlebar will fold
down.
Step 3
Flick up the bike
stand and position
the pedals so they
do not interfere
with folding the
bike.
Step 4
Stand to the right
hand side of the
bike. Locate the
locking pin at the
bottom of the
frame.
Step 5
Lift safety latch and
then fold out the
lever.
Step 6
Fold the bike in
half and hold
together with
a small bungee
cord or something
similar.
TIP: If lifting the bike remove the battery before folding down the bike to make lifting easier.
To build the bike back up just do everything in reverse.
Step 2
If removing the battery before charging,
locate key and proceed to turn clockwise
until the top of the battery lifts up.
Step 3
Grip the top of the battery and lift out of
the frame.
Step 4
To replace the battery place the the
bottom in first then press the top in place
– press firmly until it clicks into place.
Once clicked turn the key to lock it in and
remove the key.

Maintenance:
Maintaining your bike ensures you will get the most out of every
ride and increases the longevity of your RooDog electric bike.
How much you can do your self really depends on your skill,
knowledge, experience level and if you have the necessary tools
for the job.
If there is is anything you do not understand or are unsure
of how certain things work it is always best to contact your
RooDog dealer for advice.
**Please be aware general maintenance is not covered by the
warranty and is therefore a service that will be chargeable.**
Before every ride:
›Check brakes, lights, gears and tyre pressures are correct.
›Check fasteners, bolts and anything else that may come loose
over time.
›Check battery is fully charged, or at least has enough charge to
complete your planned journey.
Weekly:
›Clean the bike, including chainring and gears – (do not use
excessive water around electrical parts)
›Oil the chain, and keep all moving parts well lubricated and free
from damp.
Every month:
›Check for worn brake pads and replace if necessary.
›Check headset for looseness by rocking the bike back and
forth whilst having the brakes applied. If loose have your
dealer check it.
›Check free movement of handlebar. If tight have deal check it.
›Check cables for free movement, rust, kinks and fraying.
Replace if necessary
›Check wheel spokes are all tighjt and wheel spins true. Have
your dealer fix it if they are not. (spokes can break and wheel
rims can be bent if this is not regularly checked)
›Check tyre for tread and check sidewalls are in good condition.
Replace if necessary.
›CHARGE THE BATTERY!!!!
Every 3000 miles or annually:
›Have the bike inspected and serviced at your local dealer
including general inspection of the hub motor and all
electrical parts.
Maintenance Continued:
Tyre pressures:
›Tyres should be routinely checked for correct pressure. (this is
stated on the tyre side wall). Failure to do this will result in tyre
or rim damage, more energy will be required to propel the
bike (meaning less miles per charge) and possibly may even
result in a puncture.
Repairing a puncture:
›If you have a puncture we recommend you have it repaired by
a specialist.
›To remove the rear wheel you must first separate the electric
hub motor from the bike. In order to do this, locate the cable
coming out of the hub motor and follow it along to the quick
release (QR) plug. Disconnect the plug and all clips and ties
before attempting to remove the rear wheel.
›Prior to removing the wheel from the frame take note how
all the washers are situated so you can replace them in the
correct order in which they came off.
›When replacing the wheel back in the frame, ensure the bolts
are aligned correctly (you may need a 10mm spanner to
help) and seated right and all washers are in correctly before
tightening up the nuts to hold it in position.
›Finally reconnect the motor plug fully so the clip clicks in.
(incorrectly replaced in may result in a sudden lose of power
or may even damage the contacts connecting the motor).
Motor QR plug:
Pull/push quick release
plug. Please align arrows
correctly when replacing
to avoid damaging
terminals.
