OWNER MANUAL
3.5.1. Adjustment procedure:
Most mechanical disc brakes have one pad that stays stationary (inner pad) and one pad that moves (outer pad) in order
to apply pressure to the rotor. The rotor actually flexes toward the stationary pad so it’s squeezed between the two.
On the back side of the rotor there is a nut (inner pad adjuster) that can be turned to move the pad in or out. Turning it
clockwise will move it toward the rotor, counter-clockwise will move it away. You actually want inner pad to be a bit farther
away from the rotor than the moving pad.
A ratio of 2:1 is a good place to start, making the inner pad gap twice as wide as the moving pad gap.
Squeeze the brake lever to test the caliper. The brake should fully engage before the lever is pulled back to the
handlebar. If you’re able to pull the lever all the way to the handlebar, or they feel too soft, move the inner pad even closer
to the rotor. If you were unable to get the moving pad as close to the rotor as you’d like, you can move that one in by
turning the barrel adjuster counter clockwise. This will put more tension on the brake cable. In extreme situations, you can
even loosen the cable pinch bolt, and pull more cable through. This will actually cause the brake arm to be slightly engaged
in the rested position (however this isn’t usually recommended by brake manufacturers).

IMPORTANT INSTRUCTIONS
Safeguard your battery to ensure continued high performance. It should be recharged after each use. The normal full-cycle
battery life, if it is continuously discharged and recharged, is between 600–900 cycles after which the storage capacity of
the battery will gradually decline.
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 better in warm temperatures. When the tempera-
ture is below 50º F (10º C), the battery capacity and distance may decrease by 20%. Consequently, the travel range on a
full charge in cold environments is much less, but will return to normal when the temperature is back to room tempera-
ture. In low temperature conditions, the battery voltage may be reduced and it is possible that the low voltage protection
system will start working in advance.You should start off the bike by pedaling to avoid this.
Frequent stopping and starting, riding uphill, traveling against a strong wind, starting from a standstill, riding on rough or
muddy roads, and carrying more than one person 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 frequently stopping and starting.
•
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.
To prevent premature failure of your battery and for your warranty to remain in effect on your battery,
YOU MUST CHARGE THE BATTERY AT LEAST ONCE PER MONTH
Always turn off the bike before and during charging to prevent serious damage to the controller and to the batteries!
This electric bicycle can be used in the rain. However, the motor and other electrical parts must not be submerged in
water. The controller, motor and other electrical devices may be short circuited causing damage, which is NOT covered by
warranty, and which may create potentially dangerous situations.
DO NOT use chargers or other components other than those which have been approved by Surface 604. This company
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 electronics which is NOT covered by warranty. Do not leave the charger on for more than 10 hours!
Check all nuts, bolts, screws, and spokes to make sure they are tight before riding. If any screws, nuts, or bolts are loose,
put some thread lock on the threads and then tighten.
When riding downhill, you MUST have the power on even if you are NOT using the throttle.
4.1
Controller / brain module:
4.1.1 Controller system
The Controller system is composed of control board, driver, indicator, throttle, and brake lever. The main function is speed
control, excess current protection and low voltage protection.
4.1.2 Use and attention of controller
The main control board is located inside the battery compartment of the electric bicycle. Due to the high current, the
control board needs adequate ventilation. Please make sure that the controller is not subjected to prolonged periods in
direct sunlight or rain. When starting the electric bicycle and on steep uphill you should pedal the bike to reduce excessive
consumption of power.
We recommend you to turn the throttle slowly to engage power once the bike is in motion.

SAFETY PRECAUTIONS
•
Before operating your bicycle, inspect it carefully to avoid accidents or damage.
•
Do not drive close to other vehicles.
•
ALWAYS keep the power switched OFF until you are seated on the bike and ready to ride. Turning the power on and
then accidentally twisting the throttle can result in the bike lurching forward and may cause an accident, damage,
or injury.
•
NEVER attempt to disassemble the motor, battery, controller or throttle. This can result in injury, fire, or damage to
the bike.
•
ONLY use the charger supplied with your bike to charge the battery. Using the improper charger can result in fire or
explosion.
•
KEEP the batteries out of the reach of children.
•
Obey all traffic laws relevant to the operation of bicycles and electric bicycles.
•
Use the turn signals (if equipped) or hand signals at all times when making turns.
•
KEEP both hands on the handlebars at all times.
•
DO NOT hang objects on or under the handlebars.
•
DO NOT brake suddenly in the rain or on slippery, wet surfaces.
•
USE extreme caution when riding near other vehicles. Assume they do not see you, and be careful at intersections
and when starting from a stopped position.
•
When cleaning your electric bike, do not use a steady direct stream of water from a hose. Use a cloth to avoid
short-circuiting any electrical components. Your electric bike has a durable finish and does not need to be waxed.
Clean with a mild detergent and buff to restore its original shine.
•
Please wear a safety helmet and glasses for your own protection whenever riding.
•
Wear bright clothing to help make you visible to other motor vehicles.
•
Do not wear loose clothing that can become caught on the bicycle.
•
Do not leave the charger connected to the battery for more than 10 hours.

GENERAL OPERATING INSTRUCTIONS
6.1
Pre-ride inspection
1. Charge your battery until the green indicator light on the charger comes on, but do not allow it to charge more than
12 hours.
2. Make sure battery is in place and locked.
3. Check brakes and condition of the wheels, handlebar, and saddle. Make sure they are tight and fastened. Make sure
all quick releases are locked and secure and that all parts are in good working order.
4. Make sure all bolts, nuts and cables are tightened.
5. Make sure pedals are tightened to the cranks.
6. Surface 604 is an all-terrain bike; therefore the recommended tire pressure depends on where you ride. Check the
air pressure of the tires. Make sure they are at the recommended psi embossed on the sidewall of the tire. Maxi-
mum pressure is 30PSI.
7. Check rear light.
8. Wear a helmet.
9. Raise the kickstand.
