Product FAQ

What should I do if I still need to shift gear one the ebike?

Since attached brake levers are required to be used on the ebike compulsorily and it does not come with gear shifters, if you still need the gear system on your ebike, you may need another individual gear shifter set (7 gears). All you have to do is remove the gear system from the original brake lever and reconnect it to the new gear shifter set. Brake system and gear system should be separated on the ebike. We recommend you go to automobile repair shops with standard business license for help if you are not fimilar with DIY bike and ebike.

What is the difference between the front kit and the rear kit?/ Which one is better? Can I install front kit on rear wheel?

Front (Rear) kit is the one that motor is on the front (rear) wheel, motor generates power to drive the bike forward. We also have attached 2 photos of our 26in 48v 1000w Electric Bicycle Motor below for reference, the left one with gears is rear kit, as the right one is front kit.
Adension on the rear wheel increases as the center of gravity of the bike moves backwards when accelerating, rear kit has more efficient acceleration and stability. If you mainly use manpower and need power assistance while riding, or you don't want to change the rear wheel or brake system of the bike, front kit is able to satisfy your needs. Generally, rear kit is the better one.
We do not recommend you install the front kit on rear wheel, please only install front kit on front wheel, rear kit on rear wheel.

Ebike: What is PAS?/ How does PAS work?/ Is the level of PAS adjustable?

There is a ring of magnets mounted on the pedal crank and a sensor fixed to the bottom bracket. As the pedal crank turns, the sensor reads the rate of pedaling. The faster the pedal cadence, the faster the controller will make the motor to spin. In other words, the motor works automatically to drive the wheel when you pedal so you could save your energy. The fast you pedal, the fast the wheel runs. The level of PAS is not adjustable as there is only one mode for PAS.

Ebike: How to install PAS Sensor?/ Which side should the PAS be installed on?/ Is the PAS Sensor directional?

There are 2 different types of PAS accessories from 2 different suppliers of our ebike kit. One is the splitted body version, which is attached to YES3510, YES2467, YES1449. First, remove the non-drive crank arm which is on the side without the chainring/ sprocket (PAS Sensor can not be installed on the other side). Then remove the bottom bracket as well. Put the receiver ring (the silver part) on the frame through the axle, then thread the bottom bracket back and install the outer magnet ring (the black part) on the outside next to the bottom bracket in the same way like the disc. If your bike does not have bottom bracket, please fix the receiver ring on the frame with glue. Please note that the arrows on the magnet need to be consistent with the direction of pedaling forward, the gap between the receiver and magnet is 1-2mm, or the PAS would not work. The other one is the one piece version, which is attached to YES2463 and YES2464. First, remove the non-drive crank arm which is on the side without the chainring/ sprocket (PAS Sensor can not be installed on the other side). Then install the PAS Sensor on the axle in a certain direction as per manual.

Ebike: How to install a brake disc?/ What sizes of brake disc fit our conversion kits?

Remove 6 hexalobular internal screws (star socket screws) on the hub first (refer to pic), then align 6 bolt rotors on the brake disc to 6 screw holes on the hub and retighten 6 screws back. All sizes brake disc (mostly 140mm, 160mm, 180mm and 203mm) are compatible with the hub of all our conversion kits. Please select proper sizes of brake disc according to the spacing between the hub and fork. Choosing the sizes also depends on how the heat transfer is taking place from the disc to provide the best possible heat dissipation to avoid the disc to wear out. Bigger brake discs have better heat dissipation.

Ebike: Does the battery charge when the wheel spins freely/ brakes?

No, there is no Energy Recycle System for our conversion kits. Energy would not be recharged to the battery by spinning or braking.

Ebike: What to do if "03_info" / "06_info" on the LCD.

"03_info" represents Motor hall signal Abnormality.
1. Please try steps on the manual of troubleshooting first.
2. Please check if there is any rupture, rust or laxity on connections between controller and motor, controller and LCD. Make sure every pin and terminal is connected to another properly. Every connector is inserted in another to required position (the "'" sign), especially the 9 pins connectors of motor, controller and LCD.
3. Please contact our customer service and provide us with a video of the acceleration and operation of the wheel (off ground and without loading), the display on the LCD and all connections included.
"06_info" represents Motor or controller has short circuit Abnormality .
1. Please try steps on the manual of troubleshooting first.
2. Please lift the bike so wheels are off the ground, spin the wheel that carries motor when power is on with hands to see if a strong resistance.
3. Please ontact our customer service and provide us with a video of acceleration and operation of the wheel (off ground and without loading), battery indicator lights on the throttle and battery information on the LCD included.

Ebike: Unknow noise from the motor wheel.

1. Please lift the bike so wheels are off the ground, spin the wheel with hands (power off) to check if noise exists. If so, noise could come from contacting between the frame of bike and the wheel. Please check if something wrong on the wheel or frame of bike. Also, please check brake systems on the wheel and frame of bike (e.g. the gap between brake disc and cliper). As well as the spokes.
2. Please unplug the connection of the controller and motor and replug it again to have a try. Please make sure the connectors and pins are clear, each connector is inserted in another to required position (the "'" sign).
3. Please try to run the wheel (make sure the bike is off ground) with throttle to check if the noise occurs. If so, please take a video of this situation (noise includes) and provide our constomer service with it so we can verify the issue quickly and provide a proper resolution.

Ebike: Can I use other throttles or brake levers?

Please be sure to use the throttle and brake levers that are attached and included in the package.
1. For conversion kits with a thumb throttle, they don't work with a twist throttle instead. Similarly, those conversion kits with a twist throttle don't work with a thumb throttle instead.
2. Please kindly note that the attached brake lever carries power-off function which can stop motor from working when braking. So please do not use other brake levers in our conversion kits.

The PAS of Ebike does not work, how to fix it?

There are several reasons that may cause the failure of the PAS sensor:
1. Installing PAS sensor in wrong direction.
2. Gap between PAS sensor and axle is too wide or narrow.
3. Connection for PAS to controller is loose or defective.
4. PAS accessory is not functional.
Please follow the below troubleshooting to fix the issue:
1. Please check the direction of PAS sensor and make sure it is installed as instruction shows.
2. Please check spacing between PAS sensor and bike axel (normally 1.5-2mm gap).
3. Please make sure connection between PAS sensor and controller are sercured and connected.
4. Please connect multimeter to black and red wires of PAS sensor, see if voltage is normal as the instruction indicated.

Is there a fuse for the controller and the battery?

Yes there is a fuse on the red extension which is included in the package. The main purpose of the fuse is to provide a overcurrent protection, when the battery is unstable, which may cause the current or voltage in the circuit too high, it will burn the fuse to power off the electric bicycle. If without a fuse, constant overcurrnt may cause serious damages to the kit and even cause a fire.

Is the hub of the conversion kit direct drive and gearless?

Yes the motor is a gearless and Direct Drive motor so there is no need to shift. Compared to geared motor, direct-drive motors are capable of higher top speeds on a flat road, so if you live in a flat area and would like to get a more powerful, quieter and faster conversion kit, a direct drive motor would be the best option. Introduction of ebike motor: direct drive vs geared motor:Electric bike motors primarily come in two varieties: direct drive vs geared motor. Direct drive motors or direct-drive hub motors are large, gearless hub motors that use magnetic force inside a copper winding coil to conduct power through the motor, while geared motors or geared hub motors function via a set of planetary gears (or Planetary Gear Reduction System) that control speed. Pros and Cons:Both have their advantages, mostly concerning weight, battery efficiency, and overall horsepower. A direct drive motor offers a quiet ride with higher top speeds.Geared motors provide longer rides per charge and more torque, suitable for climbing hills and riding on varying terrains.Direct drive motors are large and heavy and are harder to foot pedal with, while geared motors are small and easier to pedal without power, but are far noisier.Geared motors don't last as long as direct drive motors.

Can change parameter or setting of LCD or conversion kit for djustment I want?

Please kindly note that the LCD and controller are the brain of each conversion kit which comes with it, so any parameter or setting of it affects riding. For safety consideration, we do not offer any instruction on adjusting parameter or setting of the LCD or conversion kit. And we do not suggest any unecessarily clicking on the LCD to avoid parameter and setting being changed. All our conversion kits are for daily commuting and please ride the ebike under local legislation. Speed limit and overload setting are not allowed as well.

Electric Bicycle Conversion Kit: Can I paint the hub to match the frame of my bike?

Yes you can paint the hub if you want it to match the frame of your bike. But please keep in mind that you need to cover the wire connections with something properly, just to make sure the paint will not spray into the wire connections. As it takes some work, we recommend you send the kit to a local auto shop to have them painted it, the man at the shop will be more professional in painting a hub.

Can you install the Electric Bicycle Conversion Kit for me at an extra cost?

We do not offer assembly service for the Electric Bicycle Conversion Kit, but we provide step by step instruction and you can follow our instruction to install the Conversion Kit. If you still do not know how to install it after looking at the instruction, you can take it to your local automobile repair shop and pay for a assembly service to let the technician install it for you, the cost depends upon your locality.

What is the torque rating of this e-bike? How much torque is good enough?

We have several e-bike kits and different kit has different torque rating. Higher torque rating means a better ability to keep turning the wheel. Generally if you live in flat area and do not go up hill often, an e-bike with around 50nm torque rating is good enough, you can use it for commuting or other casual riding.
