These electric bikes are not classified as motor vehicles; however, to drive them on the roads,
various countries have differing laws.
We have worked hard to provide you a quality product, well designed, and without defects. You too
have a part to play…… with proper care, maintenance and attention to bicycle safety rules, your
ebike will give you years of enjoyment.
Do not ride this bicycle until you have read and thoroughly understand the owner’s manual. It
contains information critical to your safety. If you have questions about the operation of this electric
bicycle, consult your authorised dealer. It is extremely important that you follow the safety
guidelines contained in this manual in order to ensure your maximum safety. If you loan your bike to
anyone make sure they also know how to operate it safely.
When using, do not exceed the maximum user weight of 120 KG and please be aware of increased
braking distances during inclement weather conditions.
This E‐bicycle is fine to use in the rain and snow, however it is not advised, to ride through puddles
deep enough to submerge the rear electronic hub as this will cause short circuitry and damage to
the electric apparatus.
The exposed metal contacts on the battery box are both positive and negative; therefore do not
touch at the same time with wet hands.
If the battery is damaged because it has been dropped somewhere or because of a biking accident,
there might be a risk of electrolytes leakage. Beware of chemical burns! And immediately stop using
a damaged battery.
CAUTION! Fully charge the batteries before the first use!

LE:SURE ELECTRIC BIKE MANUAL
Safety Precautions
Safeguard your battery to insure continued high performance. It should be recharged after each use.
The normal full‐cycle battery life if it is continuously discharged and re‐charged is about 800–1000
cycles or recharges, after which the storage capacity of the battery will gradually decline. If it is not fully
discharged and is recharged regularly, the service life of the battery will be at its optimum. The batteries
supplied are the top quality Ternary Lithium Batteries specifically designed for this vehicle.
CAUTION! Fully charge the batteries before the first use!
Failure to do this can result in decreased battery performance for the life of the bike.
Fully charge the battery each time you use the bike.
Battery performance is affected by the temperature, and is generally more efficient in warmer
temperatures. When the temperature drops below 0℃ , the battery current may decrease by a third.
Consequently the travel range on a full charge in cold environments is much less.
Frequent braking and starting, riding uphill, traveling against a strong wind, starting from a standstill,
riding on rough or muddy roads, carrying more than one person and/or heavy loads will consume extra
battery power and shorten the range. A few tips to prolong the battery life during these conditions are
as follows:
Frequent Braking – try to look ahead and coast rather than stop and go frequently.
Riding uphill or against a stiff wind – pedal to supplement the battery power.
When starting from a standstill – use the pedals to help bring you up to speed.
When the battery meter indicates the voltage is low, switch to manual power and avoid using the
battery so you don’t shorten the battery life.
If the battery is being stored, remove the battery from the bicycle and recharge it every month.
Always turn off the power and remove the key from the battery before and during charging to
prevent damage to the controller and to the batteries!
This electric bicycle can be used in the rain, however, it must not be submerged in water or puddles
– the controller, motor and other electrical devices may be short circuited as a result.
DO NOT use chargers or other components that have not been approved and tested by
Pro Rider. Pro Rider is not responsible for damages caused by the use of other products not
specifically designed and tested for use with this electric bike.
Battery Chargers contain sensitive electronics. Improper use, dropping, or sudden jolts can damage the
charger and its internal components.

Assembly Instructions
Carefully remove the bike from its box.
Front Wheel Assembly
Put the front wheel into the front fork
Remove the nuts from the front axle. Slide the wheel into the slots at the end of the forks. If your E‐bike is equipped
with a disc brake, make sure the disc for the brake slides into the front brake caliber cleanly. Replace nuts and check that
the wheel is centered into the fork and the disc is free in the brake caliber. Insure the wheel turns freely. Tighten the
nuts with a spanner. Do not over tighten.

tighten the shoe fixing nut.
Pass the inner cable through the inner cable
lead. Set the Cable with a clearance of 1 mm
between each brake pad and the rim, tighten
the cable fixing bolt.
Adjust the balance with the
spring tension adjustment screws Depress the brake lever about 10 times as far
as the grip to check that everything is
operating correctly and that the shoe
clearance is corrected before riding the bike
Pedal Assembly
Congratulations you have now assembled your ebike!
Tighten clockwise for the right pedal and
anti‐clockwise for the left pedal.

Riding Tips
1. Before riding, check to make sure the battery is fully charged, that the air pressure in
the tyres is normal, and make sure the front and back brakes are working properly.
Check the tightness of the front and back wheel, handlebar and that the seat is
fastened tightly enough.
2. When climbing steep hills a certain amount of pedalling is advisable so as not to drain
the battery power too quickly.
3. It’s a good idea to remove the battery key when leaving the bike unattended.
4. We recommend the wearing of safety helmets at all times while riding this bike.
5. Obey all traffic laws relevant to the operation of bicycles and electric bicycles.

Maintenance
Wheels: Wheels should be centred in the fork. If you hear any irregular noise from the wheels or
brakes, the wheels should be checked and repaired. Regularly check the spokes of the wheels for
tightness and rim alignment. The wheels should rotate smoothly without wobbling from side to side.
Check the bearing play of the hubs by lifting the bicycle and spinning the wheel. It should continue to
spin for several turns after you stop spinning. To check the play of the hubs try to move the rim from
side to side between the forks. No substantial play should exist. If you detect play or if the wheel is
difficult to turn, the bearings must be adjusted or replaced. Please contact a local bicycle dealer, to
have the hub bearings adjusted for new bearings.
Rims: The rims should be smooth and without cracks, breaks or bulges.
Spokes: Check the tension of the spokes regularly. About the same tension should be on all the
spokes. If there is some minor loosening of the spokes, you may tighten the nipples, but it is
recommended that you take it to a bicycle shop. If there are loose spokes or if the rim has side play of
more than 4mm, immediately have the wheel trued by a bicycle engineer. Riding with loose spokes
may cause the wheel to fail!
Tyres: Inflate your tyres to the pressure embossed on the sidewall before use of your new bike. Every
time you ride, make sure the tyres are inflated according to the pressure on the sidewall. Improper
tyre pressure will make riding more difficult, cause excessive ware, and premature failure of the tyre.
The tyre should be properly seated in the rim and the fitting of the tyre bead and rim bead should be
checked. If the tube is pinched between the rim and the tyre, it will fail when inflated. Make sure that
the tyre is not cracked or worn unevenly. Check for bulges. Check and make sure that the valve stem
is straight in the rim. Irregular tyres should be replaced immediately.
Handlebar and Display: We have created the handlebar display so that you can easily see it while
riding. Loose or damaged grips on your handlebars are dangerous! If your grip comes off you could
lose control of your bicycle.
Brakes: Riding with brakes that are worn or damaged, or with worn cables or wheels in poor condition
may result in losing control of your ebike. Wet weather hinders the brake performance. You need
more distance to safely stop in the rain or in a wet or icy conditions. Before each ride, check to make
sure your brake cables are free of obstacles, and are working properly before operating your vehicles.

LE:SURE ELECTRIC BIKE MANUAL
Batteries: There is a locking key to lock your battery onto the bike frame to discourage theft.
Do not attempt to open any of these batteries in any way! Doing so may cause chemical,
electrical, and/or fire hazards.
Lubricating the front axle, back‐shaft and pivot etc. once every three months. Oil the bike
chain and brake cable pipe at least once every month.
