Introduction
Thank for choosing a Wisper electric bicycle.
By making the decision to use an electric bike you are helping to safeguard our
environment by saving our planet’s precious resources and reducing carbon pollution.
Before you use your Wisper bike it is important that you read this manual carefully. If
there is anything you do not understand completely please contact us.
Please observe traffic regulations, and don’t lend your bicycle to anyone who is
unfamiliar with it. The bicycle can only legally be used on the road by a person aged 14
years or older.
We strongly advise you to always wear a cycle helmet when using your bicycle and if you
are unfamiliar with cycling to attend a cycle proficiency course prior to using it. Your
Wisper Works 906Alpino is not toy and should be considered a serious mode of
transport.
As with all bicycles it is important that you stay within safe limits, if you feel as if you are
traveling too quickly for the road conditions you probably are so slow down.
Test your brakes prior to using the bike every time you use it and remember the bike will
not stop as quickly in wet or icy conditions as it would on a dry road.
Before you use the bike for the first time you must make absolutely certain that it has
been correctly built. You can do this by either taking it to your nearest cycle engineer or
if you are proficient in cycle mechanics inspecting it yourself. In particular you must
make sure that the pedals, saddle, handle bars and any self assembly items have been
correctly fitted.
NEVER drink alcohol and ride your electric bike. The use of alcohol greatly reduces
reflexes and limits your ability to ride safely. Even a very small amount of alcohol will
limit your ability to be safe on the road.
Always wear an approved cycle helmet.
When you need to replace your battery please either dispose of it properly or preferably
send it back to us or our distributors and we will make sure it is properly recycled.
Happy cycling!

2 Before each use
It is important you perform a quick check of your bike every time you use it, checks
should include the following, if you find any damage or problems do not use the bike
until the problem has been solved or you have had the faulty item checked by a bike
mechanic or your retailer.

2.7 Check your battery for any visible signs of damage
3 Battery care
3.1 Before you use the battery for the first time it is best to give it a full deep charge
for 12 hours. To fully condition your new battery give it complete deep charge,
discharge cycles for the first three charges. This is achieved by charging your
battery for 12 hours and then using the bike until the battery is completely
drained. After this “conditioning” process you can then charge and discharge
the battery as and when you require for long or short periods.
3.2 If you are going to leave your battery uncharged for more than eight weeks it is
best left half charged. You should then re charge it every four weeks for two
hours to keep it in top condition.
3.3 Before setting off on any journey it is always better to have a fully charged
battery
3.4 Always remember that you use up to three times more power when setting off
under the twist throttle. To preserve the life of each charge always set off using
pedal assist
3.5 Do not expose the bicycle or battery pack to fire, heat sources, acid or alkaline
substances
