Step 1: Adjust the Handlebars

This step is particularly important to your safety. Please see the assembly video at help.chargebikes.com as well as ADJUSTMENT INSTRUCTIONS:  Adjustable Stem Instructions, in your Charge Bicycle Owner’s Manual.

1. Locate the safety release button atop the handlebar stem. Using your thumb, slide the safety release button FORWARD.

4. Rotate the handlebar 90 degrees clockwise until the handlebars are perpendicular to the bike frame.

NOTE: Make sure to keep the fork stationary—with the front light pointing forward—while turning the handlebars.


5. Push the stem release lever backdown to lock the handlebars into place.

2: Install the Front Wheel

This step is particularly important to your safety. Please see the assembly video at help.chargebikes.com as well as this Quick Start Guide.

1. Lay the cardboard block that says “Temporary Wheel Stand” flat on the ground with the printed side facing up.

2. Insert the front wheel into the cutout marked “Insert Front Wheel”. Verify the disc brake rotor is on the side marked “Brake Disc This Side”.

NOTE: The front wheel should now stay upright on its own in the temporary stand.

3. Locate the Torque Wrench (from the parts box).

4. Lift bike out of the tray and place with the front forks gently on the ground, making sure the bike is stable.

7. Slide out red spacer.

Slide out red spacer from brake on front fork. Once the spacer is removed, be careful not to squeeze the brake levers until the front wheel is installed.

NOTE: Ooops, I squeezed the brakes before installing the wheel, now what? If you accidentally squeezed the brakes before installing the wheel, the brakes will lock up. To unlock the brakes see the “How to separate brake pads on XC” article at help.chargebikes.com.

8. Move the wheel and the wheel stand in front of the front bike fork. Verify the disc brake rotor is on the same side as the kickstand.

Diagram A – Find the right seat height

To find a comfortable seat height: While sitting on the bike, move one of the pedals to the 6 o’clock position, place your heel on the pedal.  

Adjust the seat higher or lower until your knee is just slightly bent without having to shift around on the seat.

NOTE: Do not leave kickstand down when sitting on the bike. The kickstand is not designed to hold up the weight of a rider.

The finishing touch

Charge Bikes feature a valve cap sensor, so you always know when it’s time to add air. The sensors are included in your parts box. Simply screw the sensors onto the valve stems to quickly verify air pressure.
