Assembly

Front Wheel Installation

  1. First, you need a screwdriver to fix the screws on the kickstand.
  2. Secure the kickstand to the designated position of the bike.
  3. Fasten the screws on the right.
  4. Finally fix the screws on the left side, making sure they are locked to prevent them from falling off during riding.

Front Wheel Installation (Continued)

  1. Locate the quick release lever. Open the lever and remove the thumb nut and cone spring (opposite the lever). Remove the quick release skewer from the plate, keeping the washer and other cone spring in place on the lever side.
  2. Line up the fork with the axle at the center of the wheel. Make sure there's a spacer between the fork and wheel on each side. The disc brake is on the left.
  3. Hold the nut on one side and tighten the nut on the other side of the wheel onto the fork. Ensure the front wheel and quick release lever are properly secured before moving on to the next step.

Note: Closing the quick release lever should require enough pressure that it leaves an imprint in your hand. If it's too easy or too difficult to close, adjust the lever tension by turning the adjustment nut opposite the quick release lever.

Handlebar Installation

  1. Loosely secure the top of the faceplate. The Aluminum Mold Ring is only used for packaging protection. Please take it off.
  2. Insert the handlebar into the fork locknut to the desired height. Place the handlebar on the stem correctly.
  3. Center the handlebar and adjust the direction. Make sure the handlebar is centered on the stem.
  4. Use the wrench to tighten the screw and fix the handlebar stem in place. Check it again to make sure the handlebar stem is in line with the toptube, then use the wrench to tighten the screw and fix the handlebar stem in place.

Seat Installation and Adjustment

For better pedaling, safety, and overall riding comfort, positioning the seat at the right height is important. The rider's leg length is used to determine the seat's position. When you pedal, your hips should remain level and your legs should be almost fully extended at the bottom of the pedal stroke, but not over-extended.

To determine the right seat height, sit on the eBike with one pedal at its lowest point and place the ball of your foot on the pedal. Your leg should be almost fully extended (not locked out) with a slight bend at the knee.

  1. Open the quick release lever by swinging the lever open and outward fully.
  2. Move the seat up and down by sliding the seatpost in or out of the seat tube. DO NOT raise the seatpost beyond the minimum insertion marking etched into the seatpost tube.
  3. Adjust the seat and the head of the seat so it is parallel with the top tube.
  4. Close the quick release lever using your palm or finger.

Adjusting the Seat Position and Angle

To change the angle and horizontal position of the seat:

  1. Use a 6 mm Allen wrench to loosen the seat adjustment bolt on the clamp positioned immediately underneath the seat, above the rear wheel. Do not remove the bolt fully.
  2. Move the seat backward or forward and tilt to adjust the angle. A seat position horizontal to flat ground is desirable for most riders. Do not exceed the limit markings on the seat rail, which show the minimum and maximum horizontal movement allowed.
  3. While holding the seat in the desired position, use a 6 mm Allen wrench to tighten the seat angle adjustment bolt securely to the recommended torque value.

! Prior to first use, be sure to tighten the seat clamp via the seat adjustment bolt properly. A loose seat clamp or seatpost adjustment bolt can cause damage to the bike, property, loss of control, a fall, serious injury, or death. Regularly check to make sure that the seat clamp is properly tightened.

Adjusting the Suspension Fork

The suspension fork can move up and down up to 80mm to cushion bumps in the riding surface, which can make riding on a rough road or trail smoother and more comfortable. Depending on a rider's preference, the suspension fork can be locked out as a rigid fork, which will typically yield higher efficiency while pedaling.

The lockout lever (1), located on top of the right side of the suspension fork, can be turned counterclockwise until it stops to completely lock out the suspension fork's travel. To unlock the lockout lever, turn the knob clockwise until it stops. When the lockout lever is unlocked, resistance can be adjusted by turning.

Pedal Installation

  1. Locate the right-side/ left side pedal, which is marked "R" (right) and "L" (left), and should have an "R"/"L" sticker attached.
  2. Thread the right pedal onto the right crank gently by hand, turning clockwise. Then tighten the pedal by allen wrench.
  3. Thread the left pedal onto the left crank gently by hand, turning counter-clockwise. Then tighten the pedal by allen wrench.
  4. Check the chain alignment. Rotate the right pedal and crank toward the back of the bike as though pedaling backward. Watch the chain and ensure the chain runs through the drivetrain (the rear cog, chain tensioner, and around the front chainring) smoothly.

Note: If the pedal/chain doesn't run smoothly or something seems misaligned, please contact Heybike Support.

Battery Key Positions

Keyport & key positions

DescriptionKeyport & key positions
A: USB Charger
B: Battery charging port
C: Battery power button (I means on, O means off)
  1. Familiarize yourself with the key port and battery power positions before riding the bike. The photo shows the key port aligned in key position 1, in line with the small lock icon. In key position 1, the battery is in the “lock” position, with the battery locked to the frame, and the key removed so the bike is ready to ride.
  2. Anytime the battery is in key position 2 (off, unlocked from the frame), the battery must be removed from the bike before moving or riding the bike. Hold the key and slide the battery off the mount.

Start-up Procedure

After the bike has been properly assembled according to the assembly video, all components are secured correctly, a certified, reputable mechanic has checked the assembly, and you have read this entire manual, turn on the bike and select a pedal assist level following the steps below:

  1. Familiarize yourself with the battery power positions. Turn on the battery first and cover the rubber case, ready for a ride.
  2. Turn on the bike. With the battery locked in place. Locate the LCD display controls near the left handlebar grip. Hold down the M button for approximately 3 seconds until power is delivered to the LCD display and turn on.
  3. Turn on the front light or taillight if needed or desired. Long press the + button (3 seconds), the brightness of the backlight of the LCD Display will decrease. Long press the + button again (3 seconds), the backlight of the LCD Display returns to its original brightness.
  4. Select the desired level of pedal assistance (PAS) between level 1 - 3 using the + and - buttons on the LCD display. Level 1 corresponds to the lowest level of pedal assistance, and level 3 corresponds to the highest level of pedal assistance. Level 0 indicates pedal assistance is inactive. Start in PAS level 0 or 1 and adjust from there.
  5. Begin riding carefully. With the proper safety gear and rider knowledge, you may now operate your bike. On a flat surface, in a low gear (1 or 2), most riders should be able to begin pedaling the bike with pedal assist level 0 or 1. You may also use the throttle to accelerate and maintain your desired speed.
  6. The throttle is used by slowly and carefully rotating the throttle backward toward the rider. Do not use the throttle unless you are on the bike.

! Do not use the throttle while dismounted. Avoid accidental application of the throttle while dismounted; anytime you are moving the bike while dismounted, ensure the bike is powered off to prevent accidental application of the throttle.

Remove the battery

For your convenience, the Heybike battery can be removed.

  1. Ensure the battery is off. Align the key port with the appropriate off position by inserting the key into the keyport and rotating to align the key with the off icons.
  2. Carefully slide the battery upwards and lift it off the frame. Note: the battery weighs around 8 lbs and should be handled with care.

When the Battery is Removed, be careful not to drop or damage the battery when loose from the bike. Avoid damaging the exposed connector terminals and keep them clear of debris.

When Installing the Battery. Ensure the battery is turned off before sliding the battery into the frame mount receptacle. Do not force the battery onto the receptacle; slowly align and push the battery down into the receptacle. Ensure the battery has been properly secured to the bike before each use by carefully pulling upwards on the battery with both hands to test the security of the attachment of the battery to the mount.
