With the bolts still not fully tightened (loosen
them a little if you need to), adjust the height
of the stem, ensuring that the maximum height
marker is not showing.
Line up the handlebar with the wheel facing
directly forward, so that from above the bar is at a
90° angle to the front wheel.
2.1.
Ensure that the stem bolts are in place. They
shouldn’t be fully tightened yet.
Remove the e-bike and the spares pack from
the box*.
* We strongly recommend that you keep the main box and
packaging for at least 30 days in case you need to return the
e-bike.
Setting up your new e-bike
Our technicians have thoroughly checked and assembled your new e-bike, packing it carefully inside
the box. It’s almost ready to ride – just follow the easy instructions below, charge up your battery, pump
up your tyres, and you’ll be ready to go!

To adjust the angle of the handlebar stem, rst
fully loosen the bolt on the underside of the
stem (1). Then, loosen the bolts on the side of
the stem (2). Move the bars to the angle you
want, then tighten bolt (1) carefully to lock the
position. Aer this, tighten bolts (2) rmly (up to
10-15Nm if you have a torque wrench).
Check that the stem is secure by placing the
front wheel between your legs and twisting the
handlebars. If the bars and wheel move out of
the 90° alignment, you will need to realign and
tighten the stem bolts further.
Double check that the handlebars are still
90°to the front wheel, then tighten the stem
bolt (A) to secure it into position. If you have a
torque wrench, tighten to 15-20Nm (NOTE: the
bolts securing the handlebar (B) should only
be tightened to 5-6Nm). If you don’t, aim to
rmly tighten by hand without straining to your
full strength.
8.
Using your ngers, begin to t the pedals to
the matching colour-coded cranks, turning the
le pedal anti-clockwise, and the right pedal
clockwise to t. Once the pedals are loosely
installed, tighten with the supplied 15mm spanner
- be careful not to damage the threads by forcing
the pedal in. Pedals should be tightened very
rmly (30-40Nm if you have a torque wrench).

Adjust the saddle height by loosening the quick-
release latch found on the seat clamp. Raise
the saddle to a comfortable height (you may
need to make a few adjustments before nding
a comfortable height for you), then tighten the
quick-release latch until the seatpost is secure.
First, secure the basket to the upper bracket using
the two nuts, washers and bolts supplied (‘upper’
ttings, as shown). Be sure that the bolt head is
facing inside the basket.
Make sure that you fully charge your e-bike before
riding it. This will help to prolong the long-term
life of the battery. You should achieve full charge
in 4.5 to 6 hours.

If there’s a fault in the electronics of the e-bike, the display will ash LEDs to indicate the nature of the
problem. The fault must be resolved before the e-bike can be used. As a general rule, the rst check you
can perform is to see if the cables are in good condition and connected. Accidental disconnection is a
common cause of most faults.

4Frequently asked questions
Q: Why can’t I turn the e-bike on?
Q: The display shows a fault code?
Q: The electrical system has no response, what should I do next?
A: The power button on the battery needs to be turned on rst – there’s a small button on the upper
rear of the battery, and when switched on a green LED will indicate the charge level. When this
green LED is on, then press the power button on the display unit to switch on the e-bike’s systems.
If you still can’t turn the system on and you’re sure the battery has charge, check the wires and the
display connectors are all connected. If there is damage or reconnection doesn’t resolve the issue,
please contact us via email, online chat, or visit your nearest Pure Electric store for assistance.
A: Please check section 2.3 of the Set Up & Care Guide for fault codes. If the basic checks don’t resolve
the issue or aren’t possible for you to perform, please contact us via email, online chat, or visit your
nearest Pure Electric store for assistance.
A: A long press of the power button for more than 2 seconds should reset the system. If it doesn’t
and you still can’t turn the e-bike on and you’re sure that the battery is charged, check the wires
and connections for any damage or disconnection. If there is damage or reconnection doesn’t
resolve the issue, please contact us via email, online chat, or visit your nearest Pure Electric store
for assistance.
5Gears and the drivetrain
Your Pure Free Step / Free City e-bike uses a
7-speed Shimano Tourney™ transmission.
The gears are selectable by a twist action of
the Shimano RevoShi™ grip on the right
handlebar grip.
• The chain will benet from cleaning and
re-lubricating from time to time. Don’t over
lubricate – apply just enough bike chain
lubricant to prevent excess noise in use.
• Wash with a degreaser, warm water and a
so brush to remove debris from the chain,
sprocket and chainring.
• Do not use aggressive degreasers near to the
pedal, chainset of hub bearings as this may
cause accelerated wear of the components.
• Once dry, lubricate with a little light oil or a
wax ‘dry’ lubricant. Apply sparingly and rotate
the pedals backwards a few revolutions before
wiping o any excess with a cloth.
Serious injury could occur if body parts were to
be dragged in between the chain and teeth of the
system. Take particular care when rotating the
cranks while cleaning the bike in this area.
Watch out for loose trouser legs near the drive
system – a chain guard is tted but it cannot
completely avoid the risk of clothing becoming
caught in the drive system.

6Battery removal and general care
Battery unit layout:
Battery indicator display Lock
The battery is removed by unlocking it – don’t
attempt to forcibly remove the battery without
unlocking it rst. Be sure that it’s fully in place and
secured before riding – make sure that the key is
turned fully to the right and removed.
When removing the battery or handling, avoid
dropping the battery as this can damage the cells
and cause malfunction.
When re-tting the battery, be sure to give it a rm
push into position. There’s no need to force it, just
enough pressure to be sure that the connections
are made and that the locking pin can engage and
lock the battery in place before riding.
Riding with the battery unlocked may cause it to
disconnect over a bump, losing power until it’s re-
tted correctly. Always make sure the battery is
locked in place before riding.
• Only use the supplied charger to charge
the battery.
• Store the battery in a cool, dry location.
• To maintain maximum capacity during long
term storage, the optimum charge level for the
lithium-ion battery is around 40%.
However, fully charged is better than empty
– a stored at battery may not accept charge
in future.
• Charge the battery for 1 to 1.5 hours per
2-month period while unused (see charging
information below).
• Avoid washing all over with a hose. The
battery casing is rated to IPX2, and is not
designed to withstand constant spray.
• Don’t connect the positive and negative
terminals directly – this will cause a
short circuit.
• Do not expose the battery to high temperature
e.g. close to central heating radiators, direct
sunlight or inside a car on a hot day.
• Do not place the battery in water or expose to
salts, solvents, acids or bases.
• Avoid prolonged exposure to elements. It’s
waterproof and suitable for wet weather
cycling, but it’s not designed to be stored
outdoors for extended periods.
• Never disassemble the battery.
6.1 Guidelines for safe use and optimised battery life

Set-up & Care Guide 14
The charger supplied with the Pure Free City and
Free Step is an intelligent lithium battery charger.
The charger has protections including current
overload, short circuit, temperature protection
and minimum charging limit protection.
This safeguards against re and damage related
to charging.
This charger has CE certication and is suitable
for use in mainland Europe. It is only to be used
indoors and has an operating range of 0 to 30
degrees Celsius for ambient temperature.
The charger supplies 2A current to the 8.7Ah 36V
313Wh battery. Charging time to full capacity is
around 6 hours with 80% charge taking around
4.5 hours.

Cleaning and wet-weather use
Essential maintenance
8.1 Brakes
Take care when cleaning this bike. Avoid washing
the battery all over with a hose. The battery
casing is not designed to withstand constant
spray. The electrical components are water
resistant in normal use, but a jet wash can
overpower seals and force water into electrical
components or bearings.
The rear battery unit also houses the controller
which needs to stay cool so the battery carrier is
air-vented underneath. The following conditions
may direct water inside the battery carrier which
may get onto electrical contacts:
• Being on a car roof or boot rack in the rain
• Washing the rack battery area with a hose
• Heavy, prolonged rain or storage outdoors
The Pure Free Step / Free City has cable-operated
rim brakes that will need adjustment as the pads
wear. This is a job to leave to a trained mechanic
as the brakes are an obvious safety feature. If the
brake pads wear down too far without adjustment
there will be a lack of brake power or the brake
lever may contact the bars without applying
suicient braking force. A failure to stop you when
you need to will cause a serious accident.
There are barrel adjusters on the brake levers
and brake callipers that can adjust for some pad
wear if you feel the levers are getting closer to the
bar before the brake engages – turn the barrel
adjusters half a turn or more anti-clockwise to
take up some slack in the cables.
If the brakes have worn pads, need adjustment
of the cable tension or anything else that’s more
than a couple of turns of the barrel adjusters, get
it booked in for a service at your nearest Pure
6.4 Trouble Shooting – Charging (cont.)
Fault description Check items and measures
The charging indicator light is not lit Check the battery condition – when the on
button is pressed does the green light come on?
If not the battery may be fully discharged and
if le in this condition for too long it may not
accept charge again.
The charging indicator light is always red. The battery may be damaged – seek the advice of
a professional and do not attempt to dismantle
the battery.
