    -Battery troubleshooting

    1.How to charge me Magicycle ebike?

    1) Take the battery pack off using the key switch.

    2) Remove the rubber cover on the charging socket on the opposite side of the battery switch.

    3) With the battery on or off the bike, place the charger in a flat, secure place, and connect the DC output plug from the charger (round barrel connector) to the charging port on the side of the battery pack.

    4) Then connect the input plug (110/220-volt plug) to the power outlet, charging should initiate and will be indicated by the LED charge status light on the charger turning red.

    5) After the charging indicator light turning green, unplug the charger from the outlet first and proceed to remove the charger output plug from the bike charging port.

    Always charge your battery in temperature between 10 and 26 degrees Celsius and ensure the battery and charger are not damaged before initiating charge. If you notice anything unusual while charging, please discontinue charging and using the bike and contact Magicycle Bike for help.

     

    2.My battery seems to discharge way to soon, I only ride it 1 hours.

    We're sorry that your battery is having some trouble! Before we look further into the matter, please do some checking to confirm the problem.

    1) how long have you charged this battery? ( It should be at least 4-6 hours.)

    2) Was there a fan sound inside the charger when you charged it?

    3) Please take a photo of the charger light and the battery lights when they are charging.

     

    4) Use a voltmeter to TEST the battery voltage and take a photo.

     

    Please contact our support team with pics, we will check and help you quickly!

     

    3.Is is normal for the battery indicater lights to be three blue/green and one red when charging? Is it fully charged, too?

    One fact that has probably been confusing many customers is that 3 green/1red lights, instead of 4 green lights, indicate a full charge. Each light no matter red or green indicates around 25% charged. So when the 4 lights are all on, the battery has been fully charged. Then when you ride the bike after the full charge, as the remaining power becomes lower the lights will turn off one by one-- 3green/1red, 2green/1red, 1green/1red, and finally only 1 red. Only 1 red light indicates the remaining power is less than 25% and if you drain out the battery completely to 0%, the 1 red will turn off as well. In conclusion, with 4 lights on, no matter green or red, it indicates a full charge. The last one in red is designed to notice the rider that the remaining power is already lower than 25% and it's time to charge it now.

     

    4.I cannot change my battery

    If you experience any of the following three conditions, you may need to replace the battery:

    1) The voltage is abnormal, press the battery button, there is no light on the battery or none of the four lights are on at the same time, so the bike cannot be turned on.

     

    2) Only charging for 10 minutes, the charger light shows green, and it runs out of power after 15 minutes of riding.

     

    3) The battery light is blinking and cannot be charged

     

    5.Broken /craked battery case

    There might be certain bulge on few batteries due to the rough transportation, and somehow it looks like the battery is cracked, however, in most cases, it is the decal that is cracked or peeled off.Here is an easy way to fix it.

     

    6.Battery spark

    Please do not worry, the sparking from the battery is normal. As long as the sparks aren't massive, don't come with smoke, and it only sparks when connections are made, there's nothing to worry about.

     

    7.Where can I find the battery bar code and bike's serial number?

    Battery bar code: at the bottom of the battery. 

    Serial Number/ identifying number

    For the first generation,it behinds the crank, put the bike upside down

    For the second generation, on the head tube under the "Magicycle logo"

    3) The cables on the bike should be as the video demonstrated.

     

    The below pic demonstrates the PAS sensor sets in the right position.

     

     

    9.Irregular Noises

    Irregular noises from the motor can be caused by a variety of scenarios, whether something is going on internally inside the motor or the issue is purely external. If your ebike's motor is making unusual noises, the first step we recommend is checking the motor cable and the 10-core cable first, whether if there is any arced to cause this intermittent buzz reaction.

    Please check the photos and video:

    1) Motor cable

     

    2) 10 Core cable ( make sure the arrows are facing each other when you reconnect them)

    3) A rough video guide

     

    10.Motor shut off or make noise when rider climbs at low speed or when rider starts with throttle on a slope

    Please do not worry, it's a normal situation and the motor is not defective. On a slope, low speed or slow start might sometimes lead to the shut-off, which is actually protection designed to maintain the motor in great function. To avoid this, you can increase the speed when climibing and pedal a little when starting on a slope.

     

    11.Speed sensor is not working or loosing

    Please take the screw on the crank out first, then tighten the PAS sensor properly.

     

    The below pic demonstrates the PAS sensor sets in the right position.

    2.Hydraulic Break Leaking

    We apologize for the leaking hydraulic brakes. The leaking problem is caused by the bubbles inside the oil case. Please refilling the fluid to the brakes as the video indicates.

     

    3.How to Replace Brake Pad?

    When Should I Replace My Brake Pads

    A healthy brake pad material must be a minimum of 1 mm thick (the equivalent of 3 stacked business cards). Any thickness less is a sign for a replacement.

    It isn't easy to spot contaminated brake pads with the naked eye. If your brakes squeal or squeak or your rotor appears to be a darker color with oil smears, it's a sign that your brake pads may be contaminated.

    Please follow the video instruction

    6.Brakes Noise

    Noisy brakes can also be a telling sign that your ebike is in need of a check-up, repair, or even possibly needing replacement components. Excessive noise from your hydraulic disc brakes may signal that there is an issue with the rotor and brake pads. More specifically, that the brake pads and rotor have been contaminated from excessive lubrication or oil, causing the noise.

    Before determining if that is the case, use rubbing alcohol and a clean, dry rag to wipe down your rotors. An intentional cleaning generally can make the excessive noise go away. 

    Please follow the below video to adjust
