Welcome and congratulations on buying your new A2B Alva+*, the electric bike that’s taking transport in a whole new direction. It’s the
new revolutionary way to get to work, pop to the shops or just get some fresh air. Compared to jumping in the car, an ebike is a lot more
fun, easier to park and will reduce your fuel costs as well as your impact on the environment... as you’ll soon find out!

Owner`s manual
3.2 Changing components or adding accessories
Before installing any component or accessory, including a different
tyre, make sure that it is compatible with your A2B by checking with
your A2B dealer.
Read, understand and follow the instructions that accompany the
component or accessory you purchase for your A2B.
As with all mechanical components, the bicycle is subjected to
wear and high stresses. Different materials and components may
react in different ways to wear or stress fatigue. If the design life
of a component has been exceeded, it may suddenly fail possibly
causing serious or fatal injuries to the rider. Any form of crack,
scratches or change of colouring in highly stressed areas, such as
frame, fork and handle bar, indicates that the life of the component
has been reached and it should be replaced immediately by an A2B
dealer.
Failure to conform with compatibility, proper installation,
operation and maintenance components or accessories can result
in serious or fatal injury.
Using non-genuine components or replacement parts may
compromise the safety of your A2B and void the warranty.
If you change components or add accessories, you do so at
your own risk because A2B may not have tested that component
or accessory for compatibility, reliability or safety on your A2B.
3.3 Brake lever adjustment
Can you comfortably operate the brakes? If not, take your A2B to
an A2B dealer and ask them to adjust the angle of the brake levers.
Alternatively, follow the instructions below to adjust the brake lever
angle:
1. Loosen the bolt underneath the brake lever with an appropriate
allen key.
2. Adjust the angle to suit.
3. Tighten up the bolt underneath, ensuring the brake lever is firmly
xed in place.
Should you need to adjust the brakes themselves, please take
your A2B to an A2B dealer to make the required adjustments.

3.4 Seat height adjustment
The seat height may require adjustment. Ask your A2B dealer to
adjust it before you ride, however to adjust the seat yourself follow
these instructions:
To determine the correct height of the seat for the rider
1. Straddle the assembled A2B with your feet shoulder-width apart
and flat on the ground.
2. There must be at least 25 mm/1 inch clearance between the
frame height and the inside leg measurement of the rider.
Height adjustment
1. Release the seat post quick release by rotating the quick release
lever away from the seat post until it is fully open.
2. Adjust the saddle height accordingly. DO NOT raise the seat
beyond the ‘minimum insertion’ mark on the seat post.
3. Firmly grip the seat tube with your hand, and push the lever
over to the closed position towards the frame, ensuring that it
does not protrude so as to cause injury to the rider. The lever is
securely tightened when it takes a significant amount of force to
position it in the closed position. The appropriate amount of
force necessary to close the lever when it is properly adjusted
will result in an imprint of the lever in the palm of your hand.
When properly closed, it is impossible to move unless you
open it again by reversing the steps above. If you can easily
move it, open the quick release lever and tighten the adjusting
nut another 180º and try again.
4. Ensure the seat clamp bolt (seat pillar - seat post) is tightened
to 27 Nm.
5. After adjustment, ensure there is no movement in the seat
position in any direction.
Failure to correctly secure the seat can result in serious or
fatal injury.
• This owner’s manual makes no representation about the safe
use of the A2B under all conditions.

appropriate allen key.
2. Position the stem to the
desired angle.
3. Tighten bolt (C) to 17-18.5
Nm ensuring the stem is

stem, the top screw (D) is preloaded with 1-2 Nm and does not
adjust the handlebar stem. Trying to tighten bolt (D) can damage
the head set bearings.
Failure to correctly secure the bar stem can result in serious or
fatal injury. Ensure there is no play in the steering and that the
steering is working smoothly. Should you need further advice to
adjust the headset, please contact your A2B dealer.
