Before enjoying your wheel, you must first connect it to the electron wheel app for calibration.

To do this:

Connect

1. Open the electron wheel app.
2. Press the gear icon on the lower right hand corner of your screen to go to the “settings” page.
3. The first icon should read “connect”. Next to it, click the chain icon. You should see a dialogue box appear that reads “discovering electron wheels”.
4. Select your wheel in the dialogue box. The wheel icon in the upper right hand of your screen should now be solid. Also, the “connect” icon will change to “disconnect”.

 If no electron wheel is found, refer to our troubleshooting guide

Calibrate

1. Next to “calibrate”, click the graph icon.
2. Follow the on screen prompts and ride your bike for approximately 200 yards.
3. It is important to maintain a constant pedaling speed. We recommend calibrating on a level surface, and slightly depressing the brakes to maintain a constant pedal.
4. Once complete, you will see a dialogue box indicating a successful calibration

The electron wheel app is necessary to initially calibrate your wheel. After that, it’s an optional tool which allows you to track your distance and speed, battery life, assist levels, and ride mapping. It also is a great resource to access our assembly video on the go.

1 . To download the electron wheel app:

 **For iOS:**
 1) Open the App store.
 2) Search for “electron wheel”. Find the "electron connect" app. 
 3) Press the “get” to download. 
 **For Android:**
 1) Open the Google Play store.
 2) Search for “electron wheel”. Find the "electron wheel" app. 
 3) Press the “Install” button to download.

2 . Once in the app, view the assembly instructions video:

 1) Go to the far right tab in the bottom right hand corner of the screen.
 2) Press the blue play button next to the “video tutorial” row.

The electron wheel comes in two sizes to support 26″ and 700c bikes:

26 Inch: 

Tire Size =  26″ x 1.25″

Rim Dimensions = 25mm outer width, 20mm inner width, 18mm rim height

700c (28″):

Tire Size = 700 x 32C (ETRTO 32-622)

Rim Dimensions: 24.6mm outer width, 18mm inner width, 19mm rim height

Operating temperature range for the wheel is -10℃ ～ +60℃. There is a thermal sensor inside the motor, and when temperature inside the motor is greater than 80℃ the torque of the motor is restricted.

Battery charging operating temperature is between 0℃ ～ +45℃.

The wheel is water resistant and suitable for all weather conditions. However, we recommend exercising caution when riding through any standing water. You should not attempt to ride through puddles any deeper than 20cm. Doing so could cause water damage to the wheel and void your warranty.

Yes! The tire and inner tube on the electron wheel can be changed if desired or if it becomes necessary due to a flat. The process works like any traditional tire. You can complete this task on your own, or take it into any bike store for help. The electron wheel ships with the following tire and rim sizes:

26 Inch: 

Tire Size =  26″ x 1.25″

Rim Dimensions = 25mm outer width, 20mm inner width, 18mm rim height

700c (28″):

Tire Size = 700 x 32C (ETRTO 32-622)

Rim Dimensions: 24.6mm outer width, 18mm inner width, 19mm rim height

The following guide offers installation instructions for the Electron Wheel. For more help, watch our assembly video here:

Important Note: The Electron Wheel only works on bikes using rim brakes! If your bike uses disc brakes the wheel will not fit. For more information see our compatibility guide.

ATTACH THE WHEEL

Step 1
Disengage your bike’s front brakes.

Step 2
Carefully flip your bike upside down and remove your existing front wheel.

Step 3
Loosen the Electron Wheel’s quick release (located on same side as the charger port). Be careful not to loosen too much.

Step 4
Ensure the Electron Wheel’s T-lever assembly is on the same side as your bike’s chain before installing.

Step 5
Lower the Electron Wheel into place on your bike’s front fork.

Step 6
Once securely in place, tighten the quick release (on the charger port side).

Step 7
Loosen the T-­lever quick release. Make sure the spring loaded torque lever is extended as far as possible and in contact with your bike’s fork. On some bikes it will fully extend, on others it will be partially extended.

Step 8
Tighten the T­-lever quick release to lock it in place.

Step 9
Rotate the electron wheel one full cycle, pushing it away from your bike’s chain. This ensures there are no obstructions and your wheel freely spins.

Step 10
Fully close the quick release on the charger port side of the wheel so that it leaves a light imprint on your palm.

Step 11
Rotate the wheel towards your chain and make sure there are no obstructions. You will now need to carefully flip your bike upright.

Step 12
Re­-engage your front brakes.

ATTACH THE PEDAL SENSOR

Step 13
Attach the pedal sensor to the crank opposite your bike’s chain. The recommended orientation is so that the device faces inwards. IT’S IMPORTANT THAT THE SENSOR IS AS CLOSE TO THE BASE OF THE CRANK (AWAY FROM THE PEDAL) AS POSSIBLE.

Step 14
Once securely fastened, rotate your crank one full cycle to ensure there are no obstructions. If there are, you can orientate the sensor on the outside of the crank.

CALIBRATE WITH THE APP

Step 15
Download the electron app from the App store or Google Play store depending on your device. The app can be found by searching “Electron Wheel”.

Step 16
With your bike outside, turn the wheel and pedal sensor on. Open the app and select the gear wheel icon to go to the settings page (lower right). Connect your wheel, and indicate whether your pedal sensor is located on the inside, or outside, of your pedal crank.

Step 17
Push calibrate on the electron app and follow the on screen prompts. You will need to ride the bike approximately 200 meters and return to your starting position. It’s important to maintain a constant speed, and to continue pedaling throughout the 200 meters. If you’re on a decline, lightly compress the brake while continuing to pedal.

After the wheel is calibrated, select the desired level of assist and you’re ready to ride.

This video is also viewable in the electron app for easy access when on the go. Find it at the bottom of the settings page by clicking the blue arrow icon. Or on our website on the Technical Specs page.

The electron wheel pedal sensor must be installed correctly, charged, and turned on in order to operate your wheel. The sensor is wireless and simply straps on to your pedal crank. Here is a quick guide to the pedal sensor status light:

1 minute constant, then blinking

Battery Not Full:
3 second constant, then blinking

Battery Empty:
3 second constant, then off

ORANGE

RED

Battery Needs Charging:
blinking every 10 seconds

Battery Low Warning:
blinking every 5 seconds

Battery Low Urgent:
blinking every 1 second
