General Instruction Before Riding
1) Tire check - Check the tires for correct inflation pressure and for any signs of physical
damage.
2) Brake check - Squeeze the brake lever (Front then Rear) as hard as you can, push the
scooter forward and check the braking resistance.
3) Safety Circuit Breaker (P. 5) When the key is inserted and turned to the ”ON” position, the
power indicator will illuminate. If instant current is over 100A, the power will be automatically cut
off to avoid over-heating and damage. Wait for one minute and then reset the circuit breaker
located under the seat to restart your scooter. This circuit breaker is switched off before delivery,
please switch on before riding.
4) Battery Check - Make sure your scooter is sufficiently charged and always check the battery
gauge while you are riding and be sure that it does not get too low too often.
5) Steering - Inspect the handlebar for any damage. Apply the front brake and push the
handlebar up and down to check for any unusual noises. Move the handlebar in all directions to
check for any loose parts or obstructions. Any problems should be corrected before use.
6) SAFETY NOTICE
6.1. To prevent the scooter moving away unexpectedly, always turn the key to the “OFF”
position before dismounting or leaving the scooter unattended.
6.2. Always engage the rear brake when mounting or dismounting the scooter. Ensure that
you are seated on the scooter and check that the stands are clear of the ground, before touching
the throttle. If you twist the throttle before you are ready to go or while you are mounting the
scooter it may move away from you and could lead to an accident.
7) Water and Cleaning - Your scooter can be ridden in wet and rainy conditions. When riding in
rain, do not ride through deep puddles or muddy areas as excessive water will cause the motor
and other electrical components to suffer damage. During cleaning, as with any motor vehicle, be
sure to avoid soaking any electrical component during cleaning to avoid serious damage.
NEVER USE A HIGH PRESSURE WASHER WHEN CLEANING THE BIKE.
8) Parking - Your scooter should not be left in strong, direct sunlight or heavy rain for extended
long periods as this will prematurely age and damage paintwork and the general finish of the
scooters appearance and some of the electric components may overheat.
9) Riding - Never overload and ride your scooter. Prolonged use with excessive weight could
cause serious damage to the electronic and mechanic parts and void your warranty. It is
recommended that all new scooter riders enroll in rider training for safety reasons.
10) Road Rules - As with any vehicle, a scooter rider must always comply with the local road
traffic rules and regulations. Before taking your scooter out on a public road, make sure you are
familiar with traffic rules and regulations and any special requirements for motorcycles & scooters.
11) Never drink and ride - Alcohol slows reflexes and greatly limits your ability to operate a
scooter. Even a very small amount of alcohol will reduce your ability to operate a scooter safely.

Point Inspection before every use
(pre-ride check)
The following checks/operations are necessary before riding and
delivering.
ALWAYS:
1) Always Charge the batteries (observing battery guidelines) before
using and after every use.
2) Check the action of the front and rear-wheel suspension.
3) Check the functionality of all controls.
4) Check the screws, nuts and fastening parts; main and side kick stands,
suspension strut, yoke and steering-head bearing.
5) Check the lights/headlight.
6) Check all main screws.
7) Check the tire pressure.
8) Check the function of the front and rear brakes
9) Perform a final inspection of the following elements: steering,
brakes, instruments, indicator lights, lights and signal system, as well as the tires
and wheels.

Assembly Instructions
Installing the rear view mirrors
1. Rear view mirrors can be easily fixed to the handle bars between the grips
and the brake handle.
2. Screw in the rear view mirror clockwise. The rear view mirror that goes on the
left controller is curved to the left and the rear view mirror that goes on the right
controller curves to the right.
3. Fasten the rear view mirrors by tightening the nuts.
4. Clean and adjust both rear view mirrors before you ride. Adjust each mirror so
you can see the lane behind you and as far as possible the lane next to you.
When the rear view mirrors is properly adjusted you can see the edge of your
arm and shoulder while in the normal seated riding position.

Charging
● The batteries in your scooter are TS-LFP 40AHA Lithium Batteries. You
must use the factory supplied charger with an 110V (or 240V) power outlet.
● Turn off all switches while charging the battery. Plug one end to a 110V (or
240V) outlet and the other end into the charging plug on the scooter (See P.5 for
charging plug).
● The average charging time is 6 hours (90%) using the supplied LFP Charger.
To fully charge battery, charging time will be 8 hours.
● To keep the batteries in good condition, charge them when they reach 70%
discharge. Always fully charge them after each use. If the scooter is to be
stored, fully charge the batteries and store them in a dry place.
● Your batteries do not develop a memory (i.e. you do not need to run it down
completely to achieve a good charge) and the batteries can be charged at any
time in the discharge cycle of the battery.
Battery Longevity
The driver should always charge the scooter when it reaches 70% discharge. Do
not over discharge the LFP batteries. The average life of the 40AHA LFP battery
is around 2000 cycles.

Frequently Asked Questions
1. Fully charged, what is the range of the electric vehicle?
A. The Range is affected by the weight of rider, the type of terrain and the speed in
which the vehicle is driven. A range of 40 miles at full throttle and 60 miles at cruising
speed of 25mph has been recorded on a single charge, but is not guaranteed.
B. See the specification sheet for the full range and speed of the models.
2. Is riding an electric vehicle a comfortable riding experience?
A. Riding an electric vehicle is indescribably more comfortable than riding a gasoline
motor vehicle. The silence and the smoothness of a direct drive electric-motor-powered
vehicle are incomparable.
B. Quick accelerating-speed from 0 to 50mph (80km/H) takes only 10 seconds.
3. Do you have to warm-up the electric vehicle before riding it?
There is absolutely no warm-up time needed. Just turn the key and you are ready to
go. It cannot be any easier.
4. What about maintenance?
This motor bike is designed for minimum maintenance. Considering the fact that this
vehicle has no combustion engine, no transmission, no belts, no chains, no gasoline, no
ignition plugs, no carburetor, etc. Modular designed components are practically
maintenance free. The unique design of the direct drive system and the total absence of
belts or chains make this vehicle much easier to maintain than other electric scooters.
Practically any scooter dealer can do most of the maintenance that may be required.
The brushless motor is precise that so there is never a need to change the brushes.
5. What about parts, is it a problem getting parts for the scooter?
I. ALL parts can be purchased directly from the supplier including batteries, tires,
bulbs, seats etc.
6. Can the electric scooter be cleaned or washed with water without any concern?
A. As with any electric vehicle, care should always be taken when washing.
NEVER USE A HIGH PRESSURE WASHER WHEN CLEANING THE BIKE.
B. One should be careful never to pour water directly into the charger outlet, the
controller and the internal battery set when washing or cleaning.
7. Do you need to wear a helmet to ride the electric vehicle?
For safety reasons we always advise the use of a helmet. However, local law dictates
whether or not riding vehicle law obligates a helmet.
8. Is it easy to recharge the batteries?
Yes, it is very easy. The user just needs to insert the input plug of the Battery
Charger into any regular wall outlet of AC110V (or AC220V) and the output plug into the
inlet on the vehicle, which is clearly marked on page 5. This will start to recharge the
batteries.

9. How can I know the battery condition and energy level?
The display panel includes a battery gauge on the right, which clearly indicates the
power level of the batteries in your vehicle.
I. FULL: upper gauge close to letter “H”.
II. 75% FULL: second wide line.
III. 50% LEFT: middle gauge.(At this level, charging is highly recommeded.)
IV. 10% LEFT: close to red bar gauge, scooter cannot move. (Immediate charging is
necessary).
10. Can a rider get burned while riding the electric vehicle?
Riders will not get burned from riding the electric vehicle. The vehicle does not have
an exhaust pipe like in gasoline scooters. Nothing heats up.
11. Why is this product the best available in the world today?
It has a Brushless motor. We emphasize ”brushless” not just because this is the
latest technology, but because these permanent magnet motors are supremely reliable!
These more expensive motors produce high torque at low speeds, keeping an
acceptable balance of torque and energy across the whole speed range. In addition,
electric scooters do not waste energy at an idle state. Often other types of electric
vehicles on the market today will still use sealed brush-type motors that are dependant
upon brush life that build up brush dust (residue) and susceptible to wear over time
which may affect maximum speed and electrical noise or become problematic in other
ways. Because these brush-type motors are sealed, it often takes an expensive motor
replacement to get them working again.
12. What is the Manufacturer Warranty?
Go to www.x-tremescooters.com/support for warranty information on this model.
This warranty is subject to the customer/rider/owner taking due care and maintenance of
the vehicle at all times. Eventual transport expenses are at charge of the customer.
13. How to store in winter?
Take the following precaution to prevent storage damage or problems when taking
the vehicle out on the road again in the spring:
1). Switch off CIRCUIT BREAKER, clean the vehicle thoroughly (not with high-
pressure cleaning equipment!). Then treat all metal parts with corrosion-protection agent.
Use a suitable cleaning agent on all painted and unpainted trim parts and on rubber.
2). The batteries should be stored where they are protected against frost. Ensure
battery voltage is checked monthly and recharged if necessary while stored.
3). Lubricate all cables and the joints of all levers.
4). Increase the tire pressure to prevent flat tires as a result of storage.
5). The vehicle should be stored in a dry room and be covered with a weather
resistant tarpaulin.
