Product Overview

Diagram labeling the parts of the Heybike Cityrun electric bike and its handlebars. Key components include: Display Controls, Headlight Switch, Grip, Turn Signal Switch, Horn, Derailleur, Brake Lever, Throttle, Seat Post, Saddle, Battery, LCD Display, Stem, Front Light, Suspension Front, Tire, Disc Brake, Motor, Wheel, Chain, Crankset, Pedals.

Assembly

Step 1: Install the Front Wheel

Locate the front wheel. Adjust its position to align the axle at the center of the wheel with the center of the front dropout. Ensure the safety hook is inside and the nut is outside. Make sure the safety hook is locked into the front fork. Tighten the nut on the fork with a wrench. Install the front wheel bearing nut covers.

Diagram showing the front wheel being attached to the fork, with close-ups of the axle, safety hook, and nut.

Step 2: Adjust Handlebar Height and Align Stem

Keep holding the top of the front fork until the riser part assembly is finished to prevent the connection part between the frame from loosening. Loosen the Allen screw and remove the protection mold while holding the top of the front fork. Adjust the handlebar height to your need and tighten the Allen screws on the stem. Make sure the handlebar stem is in line with the top tube and adjust the handlebar in place. Then use the wrench to tighten two screws.

Diagrams showing the stem assembly, loosening screws, adjusting height, and aligning the handlebar.

Step 3: Install the Fender and Headlight

Take out the fender, remove the nut, washers, and bolt at the top and bottom of the front fork. Hold the front fender and the headlight onto the bike frame and tighten them with the screw. Tighten the screws on each side of the front wheel.

Diagrams showing fender and headlight installation on the front fork.

Step 4: Connect Cables

Find out the display cable and connect it. Find out the taillight cable and connect it, noting to connect it aim at the direction of the arrow. Connect the headlight cable, noting to connect it aim at the direction of the arrow.

Diagrams showing cable connections for the display, taillight, and headlight.

Step 5: Adjust Seat Post and Saddle

For better pedaling, safety, and overall riding comfort, positioning the seat at the right height is important. The rider's leg length determines the seat's position. When pedaling, hips should remain level and 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. 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. Adjust the seat and the head of the seat to be parallel with the top tube.

Diagrams showing seat post adjustment and saddle alignment.

Step 6: Install Pedals

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

Locate the right-side/left-side pedal, which is marked "R" and "L." Thread the left pedal onto the left crank gently by hand, turning counter-clockwise. Then tighten with an Allen wrench. Thread the right pedal onto the right crank gently by hand, turning clockwise. Then tighten with an Allen wrench. 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 it runs through the drivetrain (rear cog, chain tensioner, and front chainring) smoothly.

Diagrams showing pedal identification (R/L) and installation, and chain alignment check.

Step 7: Adjust Suspension Fork

The suspension fork can move up and down up to 80mm to cushion bumps. Depending on a rider's preference, the suspension fork can be locked out as a rigid fork for higher efficiency while pedaling.

Lockout Lever (1): Located on the top of the right side of the suspension fork. Turn counterclockwise until it stops to completely lock out the suspension fork's travel. To unlock, turn the knob clockwise until it stops. When unlocked, resistance can be adjusted by turning.

Preload Adjustment Knob (2): Located on the top of the left side of the suspension fork. To soften the ride, subtract resistance by turning the knob counterclockwise (towards "-"). To make the suspension stiffer, add resistance by turning the knob clockwise (towards "+").

Diagram showing the suspension fork with lockout lever (1) and preload adjustment knob (2).

Step 8: Secure Seatpost and Handlebar

NOTICE: Ensure the seatpost and seat are properly adjusted before riding. DO NOT raise the seatpost beyond the minimum insertion marking etched into the seatpost tube. If the seatpost projects beyond these markings, the seatpost or frame may break, causing loss of control. Ensure the minimum insertion markings are inside the seat tube. Before using the bike, always check to ensure all latches, levers, and quick releases are properly secured and undamaged. Check them before every ride and after every time the bike is left unsupervised, even for a short time. Otherwise, the handlebar stem and/or seatpost may come loose, potentially causing loss of control, damage, or injury.

Daily Care and Maintenance

Cleaning and Storage

If you see stains on the bike body, wipe them off with a damp cloth. If the stains won't scrub off, put on some toothpaste, and brush them with a toothbrush, then wipe them off with a damp cloth.

Notes: Do not clean the bike with alcohol, gasoline, kerosene, or other corrosive and volatile chemical solvents to prevent damage. Do not wash the bike with a high-pressure water spray. During cleaning, make sure the bike is turned off, the charging cable is unplugged, and the rubber flap is closed, as water leakage may result in electric shock or other major problems. When the bike is not in use, keep it indoors where it is dry and cool. Do not put it outdoors for a long time. Excessive sunlight, overheating, and overcooling accelerate the battery pack's life span.

Battery Maintenance

1. Use original battery packs; use of other models or brands may bring about safety issues.
2. Do not touch the contacts. Do not dismantle or puncture the casing. Keep the contacts away from metal objects to prevent short circuits, which may result in battery damage or even injuries and deaths.
3. Use the original power adapter to avoid potential damage or fire.
4. Mishandling of used batteries may do tremendous harm to the environment. To protect the natural environment, please follow local regulations to properly dispose of used batteries.
5. After every use, fully charge the battery to prolong its life span.

Storage and Disposal

1. Please try to store the bike in a cool and dry place between 50 °F - 77 °F (10°C - 25 °C). In extremely humid environments, the interior of the bike may suffer condensation or even water accumulation, which may damage the battery rapidly. Devices are not intended for use at elevations greater than 2000m above sea level. Prolonged exposure to UV rays, rain, and the elements may damage the enclosure materials; store indoors when not in use.
2. In daily use, try to avoid recharging the bike after completely exhausting the battery. If the battery is low, charge it as soon as possible.
3. Please charge the bike every other month to preserve the battery.

Recommended Service Intervals

Regular inspection and maintenance are key to ensure bikes function as intended and to reduce wear and tear on their systems. Recommended service intervals are guidelines; real-world wear and tear will vary with conditions of use.

Pre-Ride Safety Checklist

Notice: Before every ride, and after every 25-45 miles (40-72 km), follow this pre-ride safety checklist.

Tire Inflation and Replacement

The Cityrun employs 26"x2.5" rubber tires with inner tubes, designed for durability and safety. Proper inflation, care, and timely replacement will help ensure your bike's operational characteristics are maintained and unsafe conditions are avoided.

Heybike recommends 35-65 P.S.I for the stock tires. Always stay within the manufacturer's recommended air pressure range as listed on the tire sidewall.

⚠️ It is critically important that proper air pressure is always maintained in pneumatic tires. Do not underinflate or overinflate your tires. Low pressure may result in loss of control, and overinflated tires may burst. Failure to always maintain the air pressure rating indicated on pneumatic tires may result in tire and/or wheel failure.

⚠️ Inflate your tires from a regulated air source with an available pressure gauge. Inflating your tires from an unregulated air source could overinflate them, resulting in a burst tire.

Even tires equipped with built-in, flat-preventative tire liners can get flats from punctures, pinches, impact, and other causes. When tire wear becomes evident or a flat tire is discovered, tires and/or tubes must be replaced before operating the bike or injury to operators and/or damage to your bike could occur.

⚠️ When changing a tire or tube, ensure that all air pressure has been removed from the inner tube prior to removing the tire from the rim. Failure to remove all air pressure from the inner tube could result in serious injury.

Using aftermarket tires or inner tubes, not provided by Heybike, may void your warranty, create an unsafe riding condition, or damage your bike. If required by law, ensure replacement aftermarket tires have sufficient reflective sidewall striping.

For more information on tire or tube replacement procedures, or questions about tire inflation, visit heybike.com/pages/help-center or contact Heybike Support.

Your cables, spokes, and chain will stretch after an initial break-in period of 50-100 mi (80-160 km), and bolted connections can loosen. Always have a certified, reputable bike mechanic perform a tune-up on your bike after your initial break-in period. Regular inspections and tune-ups are particularly important for ensuring that your bike remains safe and fun to ride.
