Rider weight limit
The bike has a maximum weight limit of 85 kg (187 lbs), this includes
the rider and anything the rider is carrying, for example a back pack.
• A-bike Plus pump (optional)
• A-bike Plus Bag (optional)
The inclusion of the A-bike Plus Bag and A-bike Plus Pump may
vary in different countries.
Please note that riding the bike with under inflated tyres will
damage the bike and therefore it is highly recommended that users
use a Schrader pump with a pressure gauge. Also due to the high
pressure and low volume of air it is advised to use the A-bike shock
pump which minimises air loss when dis-attaching the pump.
Not a mountain bike
The A-bike Plus is designed for smooth roads and it’s lightweight
construction means it’s not suitable for rough surfaces, off-road riding.
Do not attempt stunts on the bike.
Under inflated tyres
Riding the bike with under inflated tyres will damage the bike, please
ensure the tyres are inflated to 90 psi (6.2 bar).
Quick release levers and locking buttons
When opening the bike ensure that the locking buttons pop out. The
two quick release levers here should be hand tight and firmly secured.
Don’t step on the crosspiece
The crosspiece is not designed to bear any load. Do not stand on or
attach anything to this beam.

Adjusting saddle height
When riding the A-bike Plus it is important to remember to abide by
local bicycle riding laws.
Before riding the bike check the seat height is
adjusted, the tyres are inflated and the brakes work.
Ride defensively and be vigilant of other road users. Always leave
a large enough gap between you and obstacles, slow down and
stop if necessary.
Watch out for uneven surfaces and pot holes.
When riding in the dark you should wear high visibility clothing and
use lights when appropriate.
Wet weather will reduce grip and increase stopping distances;
ride slower if necessary. Icy conditions should be avoided entirely.
Windy conditions can severely effect riding stability.
Always wear a helmet when riding.
Always wear suitable shoes, sandals are not appropriate.
Avoid loose clothing and anything that may get caught in the
mechanisms of the bike.
Become familiar with riding your bike slowly and in a safe environment before heading into areas with other traffic.
Store you bike securely and safely in a clean and dry area to avoid
damaging the bike.
Choosing the Correct Saddle Height
With both feet flat on the ground adjust the saddle height so that
you can comfortably sit on the saddle.
1. Unlock the Seat Post quick release
clamp.
2. Slide the Seat Post vertically to
adjust the Saddle position as required.
The minimum insertion line should
NOT be visible, it should be inside the
outer tube.
3. Once the desired Saddle position
has been selected, make sure the
saddle is positioned forward and then
lock the Seat Post quick release clamp
so that you cannot twist the saddle out
of alignment.

Riding Safely
Checking the tyres
Adjusting the brakes
Under inflated tyres make the ride less comfortable and less efficient, turning and pedalling become difficult. It will also damage the
bike and could invalidate your warranty.
If the brake band is knocked it is possible for it to become
misaligned with the braking hub and wheel. If this happens it may
be necessary to gently bend the band back into shape. Care must
be taken not to cause strain around the brake band mounts. If the
brake band rubs against the wheel it can be gently bent away.
To check the pressure it is possible to visually inspect the tyres
by pushing on the outside of the tyre, they should be very firm.
However for an accurate reading a pressure gauge is required.
SETTING UP
Take care when accessing the valve and avoid pulling on it or
using excessive force, as this can cause the valve to tear away
from the innertube.
You should also take this opportunity to check the tyre’s tread, to
check for damage to the tyre and for debris in the tyre. Spotting a
piece of glass and removing it now could prevent a puncture later.
Tyres should be replaced when they become worn.
Hot brake bands and brake fade
The band brakes will become hot when used, be aware of this when
storing and handling the bike, allow the brakes to cool.
Brake fade may occur when used for long periods of time.
SETTING UP
Riding the bike with under inflated tyres will damage the bike, please
ensure the tyres are inflated to 90 psi (6.2 bar).
Adjusting brake bands
Only adjust the brakes when the bike is fully unfolded and extended
as this effect the brake cables.

Maintaining your bike
Like all bikes the A-bike Plus requires some simple
maintenance to run at it’s optimum and prevent parts
from becoming damaged.
It is vital that you maintain your A-bike Plus!
If you notice in a small change in performance of the bike we recommend you check the bike as this is often a sign of the beginning of a
potentially serious problem.

MAINTENANCE
Folding the bike (2)
Maintenance
Clean the bike - dirt is the enemy of a smooth running bike and can
eventually cause parts to seize in addition to causing corrosion.
Carry out regular cleaning and corrosion protection of all parts of
your A-bike Plus.
We recommend washing the A-bike Plus with a gentle flow of
water, or from a bucket, using a damp cloth. This is also a great
opportunity to visually inspect your bike.
Inspect the bike for damage
Damage to parts can result in sudden failure of that part. The bike
should be regularly inspected, looking for cracks, discolouration of
material, scratches and loose fastenings. If damage is found you
should contact the vendor and seek advice before attempting to ride
the bike.
Clean the chain and lubricate regularly, this is vital to reducing
wear to the bike and efficiency.
REPAIRS
MAINTENANCE
Check your brakes - you should be able to stop the wheel from
turning without the brake lever touching the handle grip. Test this
when stood by the bike, NOT while riding it! If you need to adjust it
look at the Repairs section of this user guide.

Adjusting chain tension
Fixing a puncture
The A-bike Plus chain tension is preset in the manufacturing
process. If the chain needs to be replaced it should be referred to a
bicycle mechanic or an A-bike Plus dealer.
If you get a puncture you can repair this using a puncture repair kit
suitable for high pressure applications.
If the chain is too slack it may be noisy and if too tight it may make
it difficult to turn the wheel. When viewed the chain should have
some slack.

Fixing a puncture (3)
Replacing a tyre or puncture repair
1. Remove the wheel as shown in the
previous pages.
2. Remove the dust cap from the
valve and release the remaining air
from it by pushing the centre pin in.
VERY IMPORTANT: When reassembling always make sure the valve
on the tube faces clockwise, and tyre
tread faces the correct direction. Inflate
tyre to 90 psi (6.2 bar).
Note: Using tubes not designed for the A-bike Plus wheel hubs
could result in the valve jamming when riding. This could lead to
serious injury. Only use tubes designed for the A-bike Plus and
ensure these fitting instructions are followed.
3. Use PLASTIC tyre levers to
remove the tyre.
Take the tube out of the tyre and
repair the puncture with a puncture
repair kit or simply replace inner
tube/tyre. When repairing a puncture,
follow the puncture repair kit’s manufacturer’s instructions. Only use tubes
and tyres sourced from your A-bike Plus supplier.
