1 Introduction
Thank you for choosing a Accolmile electric bicycle.
Before you use your Accolmile electric 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 do not lend your bicycle to anyone who is unfamiliar with it.
We strongly advise you to always wear an approved cycle helmet when riding your bicycle. If you are
unfamiliar with cycling we advise attending a cycle proficiency course prior to using your new bicycle
on the public highway.
When using any bicycle, it is important that you stay within safe limits; if you feel as if you are
travelling too quickly, you probably are.
Always test your brakes prior to using the bike and remember the bike will not stop as quickly in the
wet as it would in the dry!
Before you use the bike for the first time, please make absolutely certain that it has been correctly
assembled. 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 assembled items have been fitted correctly.
Avoid consuming alcohol before you ride your electric bike. The use of alcohol greatly reduces
reflexes and limits your ability to ride safely.
If you need to replace your battery, please either dispose of it properly or preferably send it back to
us or one of our distributors and we will make sure it is properly recycled.
Above all, enjoy your Accolmile bike, happy cycling!

2 Caring for your Accolmile bike and pre-use checks
Your Accolmile bike has been thoroughly tested at the factory prior to delivery and undergone a pre-
delivery inspection by your Accolmile Stockist.
It is very important that you check the bike thoroughly before its first use. Equally important are
frequent and regular spot-checks, as they will protect you and your Accolmile bike.
Please read this manual carefully. Only on full understanding all of the functions of this electric
bicycle should you attempt to use it.
This mountain bike can be used for riding on the flat roads and climbing, more it is suitable for
riding on compound road conditions such as mountain, forest road and gravel. But it shall not be
used for off-road, sports and performance downhill. If consumers violate the regulations for off-road,
sports and performance downhill and cause accidental injury, they shall bear their own responsibility.
Before you set off for the first ride: suggested information to measure and adjust saddle height to
suit rider height:
Please try to confirm whether the pedals are locked before riding. If they are loose or damaged, they
need to be adjusted before use.

2.2 Before each use
It is important you check your bike prior to each time you use it. Checks should include the following:
(If you do 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 an electric bike mechanic or your retailer).
2.2.1 Check the tires for any visible damage.

2.2.6 Check the reflectors are in place and the lights are working.
2.2.7 Check the battery for any visible signs of damage.
2.3 Battery care
2.3.1 Your Accolmile bike comes with a high quality lithium ion battery. All lithium batteries need
to be looked after to ensure years of full use. The latest Accolmile batteries come with new
technology installed to assist you in looking after your battery and will be dealt with
separately. Following these easy steps will ensure the long life of your battery.
2.3.2 Recharge your battery after every use if possible. Keeping your battery charged extends its
life and your bike is always ready to go.
2.3.3 You do not have to “condition” your battery by charging and discharging before it’s first use.
This was the case with old lithium ion technology but is not necessary on modern batteries.
2.3.4 Never leave your battery completely discharged for more than 24 hours. Voltage dropping
below minimum for any length of time will cause serious damage to your battery cells.
2.3.5 Recharge your battery every month even if you are not using the bike. Most lithium ion
batteries will continue to discharge even when the bike and battery are turned off. If your
battery falls below minimum Voltage, it may not be recoverable.
2.3.6 Do not expose the bicycle or battery pack to fire, heat sources, acid or alkaline substances.
2.3.7 When leaving your bicycle during hot weather, always leave in a shaded well ventilated area.
2.3.8 For best results, always recharge and store the battery at room temperature.
2.3.9 Before unloading the battery, make sure it is turned off and unload the battery using its
handle.
2.3.10 Further information on user responsibilities and battery maintenance are included in the
warranty section of this manual.
The most common cause of battery failure the owner not keeping to points 4 and 5 above.
This is the most common reason for customers to need to replace batteries. This is
particularly noticeable in the spring when customers are using their bike for the first time in
the new year. We get most calls regarding failing batteries during this period.
IMPORTANT
If your battery is damaged due to your leaving it discharged, or not recharging when
advised as per this manual your battery is not covered by our warranty.
Battery safety
2.3.11 i. Never leave a battery connected to the charger or mains power over-night.

7
ii. Never recharge a battery outside, in damp conditions or in temperatures less then 0
degrees centigrade.
iii. Never open a battery case, try and fix the battery or give it to any one other
than a registered Accolmile Stockist for maintenance. (Failure to comply will void the
warranty)
iv. If a battery is or appears to be damaged or overheating for any reason, do not use the
bike and immediately return the battery to your retailer for advice and a safety check.
IMPORTANT
Ignoring any of the safety rules above could cause serious injury or fire.
2.4 Recharging your battery
2.4.1 Before charging, make sure the charger is turned off and connect your battery to the charger
at the charging socket. Plug the charger into a mains socket and turn on the mains socket.
A red lamp will light up on the charger indicate the battery is charging. When the red light
turns green, the battery is fully charged. To optimize battery life, leave the charger
connected for a further hour and then turn off the charger and disconnect it from the
mains after charging. Always disconnect the charger from the mains before disconnecting
the charger from the battery. It is possible that the battery will take up to twelve hours to
charge on the first three charges.

should never be raised beyond the maximum permissible, indicated by a safety line around
the tubes. The recommended torque (tightness) of crucial fixings is as follows:
Front axle nuts. 46N.m
Back axle nuts. 70N.m
Handlebar and stem clamp bolts. 12N.m
Handlebar stem expander bolt. 10N.m

Other general torque settings depend on the thread size. M4: 2.5-4.0N.m, M5: 4.0-6.0N.m,
M6:6.0-7.5N.m.
2.6.3 Your bike has a rear derailleur that will automatically tension your chain. However, if the
chain becomes loose or frequently comes off the front chain-wheel, please seek advice from
the dealer.

and touching the handle bars.
2.6.5 Warning: Handlebar hand grips or tube end plugs should be replaced if damaged, as bare
tube ends can cause injury.
2.6.6 Brake pads must be replaced if the pad material wears to less than 1mm.
IMPORTANT! braking distances increase on wet or icy roads.
