3. Assembly and Setup

Your Jasion Electric Mountain Bike may require some assembly upon arrival. Follow these general steps. For detailed visual instructions, refer to the separate assembly guide or video provided by Jasion.

3.1 Unboxing and Initial Inspection

1. Carefully remove all components from the packaging.
2. Inspect for any shipping damage. Contact customer support immediately if damage is found.
3. Verify all parts are present according to the packing list.

3.2 Assembly Steps

1. Handlebar Installation: Attach the handlebar to the stem and tighten the bolts securely. Ensure the handlebar is centered and aligned with the front wheel.
2. Front Wheel Installation: Install the front wheel into the fork dropouts. Ensure the disc brake rotor is correctly seated in the caliper. Tighten the quick-release skewer or axle nuts firmly.
3. Pedal Installation: Identify the left (L) and right (R) pedals. The left pedal tightens counter-clockwise, and the right pedal tightens clockwise. Apply a small amount of grease to the threads and tighten them firmly with a wrench.
4. Seat Post and Saddle Installation: Insert the seat post into the frame's seat tube. Adjust the saddle height for comfortable pedaling with a slight bend in your knee at the bottom of the pedal stroke. Secure the quick-release clamp.
5. Battery Installation: Slide the battery into its designated compartment on the frame. Ensure it clicks into place securely. Use the key to lock it if applicable.

3.3 Initial Battery Charge

Before your first ride, fully charge the battery. Connect the charger to a power outlet and then to the battery charging port. The indicator light on the charger will show the charging status. A full charge typically takes 5-6 hours.

4. Operating Instructions

Understanding how to operate your electric bike's features will enhance your riding experience.

4.1 Powering On/Off

Locate the power button on the display unit. Press and hold it for a few seconds to turn the bike's electrical system on or off.

4.2 Pedal-Assist System (PAS)

The bike features a pedal-assist system with multiple levels. Use the '+' and '-' buttons on the control panel to adjust the assist level. Higher levels provide more motor assistance, making pedaling easier. The display will indicate the current PAS level.

4.3 Throttle Operation

If equipped, the throttle provides power on demand without pedaling. Gently twist the throttle to engage the motor. Use the throttle responsibly and be mindful of your speed.

4.4 Gear Shifting

Your bike is equipped with a 7-speed gear system. Use the shifter on the handlebar to change gears. Shift to lower gears for climbing hills and higher gears for flat terrain or descents. Shift smoothly to avoid strain on the drivetrain.

4.5 Braking

The bike uses disc brakes for effective stopping power. Apply both front and rear brakes simultaneously for balanced and controlled stopping. Avoid sudden, hard braking, especially with the front brake, to prevent skidding.

4.6 Headlight and Horn

The integrated headlight and horn are controlled via buttons on the handlebar. Use the headlight for visibility in low-light conditions and the horn to alert others to your presence.
