make quick decisions.
9. Use of Personal Protective Equipment
To avoid injury when using EV4, wear protective equipment. Equipment includes bicycle helmet, knee and elbow
pads. Protective gloves are recommended during repairs and maintenance.
10. Use
10.1. How to operate the EV4
When driving on the EV4 BIKE, sit on the seat; hold your hands on the steering wheel, feet when stopped on the
ground and while driving on pedals. Keep your hands and feet away from all the mechanical components of the vehicle such as
steering suspension or drive system. Do not touch: vehicle mechanisms drive system and vehicle suspension during operation.
Before using the EV4 BIKE for the first time, charge the battery to 100%.
You should push your foot slightly off the ground while pressing down with the other foot on the pedal. You need to
move from 1st gear. When you start pedalling, the engine starts to assist if the ASSIST level is greater than 0. As the speed
increases, you can change gears to higher if the terrain allows it. Shift upwards by pressing the blue derailleur button and down
with the black derailleur lever. Both activities are done with the thumb of your right hand. You can change the power of the
push button up or down on the control panel while driving. The equilibrium should be kept in the same way as in two-wheeled
vehicles. Twisting is done by simultaneous body balance and steering turn. The vehicle stops after the pedalling has been
stopped and the right and left levers of the brake are pressed simultaneously, ensuring that the wheels are not locked. This may
cause loss of steer ability, balance and tipping. When stopping in the final phase, you should support with your foot.
The maximum tilting of the vehicle while making a turn is 30 degrees. Increasing the tilting of the vehicle beyond 30
degrees may cause the suspension to fall against the limiter and consequently damage the vehicle and lead to imbalance.

about 1 second when it receives a
signal from the crankshaft sensor).
9. When driving, you can change the
power of the aid with buttons (upper
and lower) as needed, and adjust to the
pitch of the ground by changing the
gear lever
10. The driving computer is equipped with
the ability to start the engine without
having to pedal. To start this function,
hold for about 2 sec. The bottom
button on the control panel. The engine
will start but the vehicle speed will be
limited to 6 km/h.

10.4. Charging and fuse description
EV4 BIKE is supplied with a Li-Ion 37V, 14Ah battery. In order to properly charge the battery, use the charger
supplied with the vehicle. You will need a special 37 V charger for Li-ion batteries. It is forbidden to use a charger other than
the original charger. Using a charger other than the original charger may result in electrical damage, short circuit, fire and
personal injury. It may also cause permanent damage to the battery and the vehicle's electrical system.
The charger must first be connected to the vehicle then to the network. Charging socket is on the right side of the
frame at the rear. Take the lid off the socket and then plug in the charger plug.
The charger must be disconnected from the vehicle when the vehicle is fully charged (charge will not occur after
100%). It is indicated with a green lamp on the charger. Secure the vehicle's charging socket when charging is complete. After
the charge is complete, one can start the vehicle with the key. Disconnect the charger before starting the vehicle. Do not
connect any equipment or short connectors to the charger socket. The charger for the EV4 does not charge other batteries.
EV4 vehicles have fuses for electrical wiring. Fuses are located on the battery casing. If the vehicle cannot be started
or the battery won’t recharge check whether the fuse has been blown. For this purpose dismantle the frame cover with the
screws and check the fuse in the battery. Locating the cover and fuse holder bolts is shown in the photographs.
If the vehicle cannot be started and the fuse is working, contact the manufacturer / service. Do not perform repairs on
your own. The EV4 BIKE uses a 30A main fuse. When it is necessary to replace the fuse, it is necessary to use a new one with
the same current.
It is forbidden to use a fuse of other parameters. This may cause damage to the electrical system and fire.

11. Setup
11.1. Seat height
The seat is equipped with a bicycle seat tube with variable height adjustment. Loosen the pipe clamp to change the
height. After fixing the height again tighten the fixing. Pay attention to the proper crimping force of the tube. Insufficient force
of clamp may cause the seat to fall while driving. This situation is dangerous for the driver.
11.2. Braking system
The brake system has two independent front and rear brake circuits. The front wheels stop using the right lever and
the rear wheels stop using the left lever. The braking system is very effective, so excessive use of the brake lever can cause the
wheel to block and consequently you may fall into a slippage and lose balance. Operate the brake lever with your index finger
and middle finger instead of your whole hand. Front wheel locking may cause lack of front steering and cause the vehicle to tip
over. Before going full speed, one must practice using the brakes to properly control the vehicle, If squeaking occurs during
braking, it has become uneven in individual wheels, brakes have become ineffective, or other disturbing braking problems are
observed immediately replace the brake pads.
11.3. Shock absorbers
The hardness of the shock absorbers should be adjusted to the weight of the driver. Excessive deflection of the shock
absorber can cause damage to the vehicle and damper and cause discomfort to the driver. The shock absorber must be set as
follows: The person who will drive the vehicle must sit on the vehicle with both feet on the ground. The second person at the
same time should check the damper's initial deflection, which should be about half of total stroke. For DT SWISS shock
absorbers with a length of 190 mm the total deflection is 50 mm and the initial deflection (when the driver sits on the vehicle)
in the front and rear shock absorbers should be 25 mm. Adjustment of hardness is done by pumping the shock absorber with a
pump and dropping pressure is done by venting the valve. Approximate pressure in the front shock absorber is 2-3 bars while
in the rear 4-6 bar. Maximum pressure cannot exceed 18 bars. Exceeding this pressure can damage the shock absorber.
Damper adjustment should be unscrewed towards the softest damping. The shock absorber should be set to: unlocked.
