General Conditions

1. Safety: Safety comes first, so before you ride on the street, practice riding the bike somewhere away from cars.
2. The seat is adjustable. Adjust seat to be comfortable and also easy to put your feet on the ground when you stop.
3. Wear a safety helmet and give proper signals when turning left or right.
4. Maximum bike speed is 20 miles per hour (33 km per hour).
5. The bike is designed for a rider on flat ground whose average weight is below 165 lbs (75 kgs). When riding uphill, use your leg power along with the Hub motor assist. Also switch gears to save energy, and avoid riding up steep hills.
6. Avoid riding on rough roads due to the possibility of tire damage. If the wheel is deformed, the controller will no longer work. Avoid drain grates, pot holes, ruts, soft road edges, gravel and sand.
7. Avoid riding on rainy days and during evenings, etc. If you have to ride under inclement weather or at night, use a headlight and reflective lights on the bike and ride close to the curb.
8. Do not carry heavy objects or people on the bike.
9. It is prohibited to ride the bike whenever your physical condition is impaired (by alcohol, medicines, etc.).
10. Brakes: Before riding, check front and rear brakes to make sure that they are working. Also check bolts, to verify that they are tight. Speeding up or down hills will reduce the efficiency of the brakes.
11. When you want to stop, slow down using both front and rear brakes to avoid losing your balance.
12. Electrical: Please be careful when plugging in control wires. Wires tangled or plugged in improperly could damage the electrical system.
13. Keep children and objects away from batteries to avoid the danger of burns. Also remember to put plastic covers on plugs to avoid accidental shorting.
14. Charger: The battery power in the bike is designed only for our charger. Please check voltage on the socket before charging, and make sure that it is within the range of 10 and 14 volts per 12 volt battery.
15. Do not put any liquids into the charger. It is enclosed in a plastic box which functions to release heat. Only use charger indoors and make sure there is plenty of fresh air and space while charging the battery pack.
16. Avoid Theft: To avoid theft, lock the bike, turn off the power, and remove the key.
17. Maintenance: Please keep bike properly maintained to insure its longevity.
18. If the bike is unused for any length of time, pull electrical wires from the bike and turn off the power switch (key) on the controller box. Take care of your key.
19. Insurance: Please get accident insurance, ride carefully and respect life.

Instructions

1. Indicator LED (beside the controller key)
   1. Controller: The lit LED indicates that electricity supply is normal.
   2. While the bike motor is off:
      1. Turn on the key. The LED will light up. If the bike is left sitting longer than 5 minutes, the power will automatically shut off. In order to ride the bike, the rider must turn the power on again. (Key: on-off-on)
      2. If the battery power is low, the LED will be flashing. Please charge the batteries regularly to keep it full.
      3. If the power is low while the bike is running, the LED will start flashing. At this time, it is necessary to charge the batteries.
      4. The Front Wheel (and pedal sprocket if purchased with pedal assist option) is assembled with sensors. If the sensor is out of order or in the wrong position, the LED will be flashing. If everything is normal, the LED will be off, and then will light up. If the bike has continually been running, then the LED will shut off automatically.
      5. The LED will let you know:
         1. if the batteries are full or empty
         2. if the sensors on the front wheel (or pedal) are out of order or out of position
      6. If the controller is out of order, please send it to your dealer or distributor for repairs. The warranty is voided if the operator opens the control box.
2. Front Wheel Sensors
   1. A sensor is positioned on the left front fork and the matching magnet is put on the left side rim of the Hub Motor on the front wheel. If magnets become damaged or loose, the motor will not run. (Replacement magnets and sensors may be purchased at local stores. Simply replace new ones in the same position as the old ones.)
   2. The best reactive distance for sensor and magnet is between 2mm and 8mm. Please refer to the photo to position sensor and magnet.

3. Pedal Sensors
   
   1. If your bike is activated by pedaling, then a pedal sensor is positioned on the lower end of the seat shaft and the matching magnets are put on the sprockets of the pedal. If magnets become damaged or loose, the motor will not run. (Replacement magnets and sensors may be purchased at local stores. Simply replace new ones in the same position as the old ones.)
   2. The best reactive distance for sensor and magnet is between 2mm and 8mm. Please refer to the drawing above to position sensor and magnet.
   
   
4. Swivel Throttle Model
   
   1. If your bike is activated by a swivel throttle, the bike must be traveling about 3 miles per hour before the motor is activiated. This prevents accidental starts when the vehicle is standing still. Once you reach walking speed, you may twist the throttle to power the Bike.
5. How to Turn On the Electric Motor
   1. Please check to see if the plug from the front wheel motor is loose. To avoid burning out the motor use vinyl electrical tape to separate the two wires.
   2. Please use the key to turn the power on and off. Be sure that the electrical wires are plugged in and in the right position before you turn on the power.
   3. Push on the pedals to gain speed until you reach the average speed of a pedestrian, at which point the motor will automatically turn on. Don't stop pedaling. One turn of the pedal is typically 3 seconds. The faster you pedal, the faster the motor will go. If you stop pedaling or you spend more than 3 seconds to make one complete turn of the pedal, the motor will stop automatically.
   4. If the speed of the bike is slower than the average speed of a pedestrian, the motor will stop automatically.
   5. If the motor is overloaded or turned on for a long period of time, it will cut off automatically. After it has cooled down it will start up again.
   6. If the battery pack is low, the motor will stop. The batteries need to be charged as soon as possible. Please do not turn motor on and off. This will damage the battery pack.
   7. Reasons the motor stops working
      There are several possible points of failure in the Hub Motor's electrical system, and careful analysis is necessary to be assured of reliable operation. Following is a list of problems that can cause failure:
      1. The key is not turned on.
      2. The connector plug is loose on the front wheel hub motor.
      3. Sensors in the Front Wheel or Pedal are in the wrong position. The magnet or sensors are loose or damaged.
      4. If the motor stops running for 5 minutes, the controller automatically cuts off.
      5. If the temperature of the motor is too high, it will cut off.
      6. If the carbon brushes in the motor are worn down, it is necessary to replace them.
      7. The plug is loose in the battery case.
      8. The fuse in the battery case is burned out or loose.
      9. The voltage in the battery pack is low.
      10. The battery pack is getting worn out and needs replacing.
      11. The rider doesn't push the pedal continuously (Pedal assist model)
6. Batteries
   1. The four Lead-Acid batteries (7-10Ah, 12V x 4pc = 48V) are connected together in series.
   2. The batteries need to be charged every month, if the battery pack isn't in use after a long time.
   3. Lead-Acid batteries do not memorize their power capacity, therefore they need to be charged frequently. For long life, after the battery pack is discharged, it needs to be recharged promptly.
   4. Lead-Acid batteries have a limited useful lifetime. If a fully charged battery has a riding distance reduced to half that of the new bike, then the electrical power is insufficient and the battery pack is worn out. Please take the old battery pack to the distributor for replacement. For public safety, recycle -- do not throw batteries away.
   5. To pull out the battery pack, push case bottom up first to make it easier to remove.
   6. Please follow the wiring diagram when rewiring a new set of batteries or plugging them in, to avoid improper use. If you have questions, contact your dealer.
   7. There are two fuses (30Ah) inside the battery case. These will short circuit if the electrical plug is in contact with metal or if the system is used improperly. If the fuse should cut out, clear the electrical obstructions and replace the fuse.
   8. Don't open the battery case if the battery is in use.
   9. Please put the plastic protective cover on the plug while it is not in use. Keep battery pack away from children, metals, coins, screws or jewelry.
   10. Only use charger which is specified for El Ayudante's Lead-Acid batteries. Other battery chargers may overcharge and cause damage.
7. Charger
   Please read instructions for the charger carefully.
   1. Instructions for the LED:
      There are 6 indicator LEDs

      power	light	instruction for power
      L	red	lowest power
      Ml	red	low power
      M2	red	middle power
      H	red	high power
      full	green	The flashing light indicates charging -- if it stops, the battery is fully charged. After 48 hours, pull the plug because the battery is full (the charging time is 3 to 5 hours)

      
      

   2. While charging, if the Green LED on the charger doesn't light up for one minute, it means one of the following:
      1. the fuse in the battery case is burned out or loose.
      2. The plug is loose.
      3. the charger plug is not put in proper position or it may be damaged.
      4. It has automatically cut off the power while charging, because the temperature is too high.
   3. Inside the charger there an overheat protection instrument. When the temperature is too high, the charger will turn off and the LED will also be off. The charger will start again after it has cooled down.
   4. Only use the charger indoors with plenty of fresh air. Please keep away from flammable objects. Use only the charger for recharging the battery pack.
   5. Avoid using charger in a hot, humid environment
   6. If charger smokes or has a strange odor, pull the plug immediately to avoid possible fire. Send the charger back to your dealer.
8. Tire Air:
   1. Rear wheel: the rider should keep tire pressure between 60 & 70 Psi. Do not over-inflate, or the tire may change shape, causing damage to the rim.
   2. Front Wheel: please keep the air pressure between 50 to 70 Psi. The tire must keep proper pressure for comfortable riding. If the air pressure is too low, the rider has to push the pedals harder.
