11. Before riding - be sure that any and all axle guards, chain guards, or other covers or guards supplied by the manufacturer are in place and in serviceable condition.

12. Before riding - be sure to check that the tires are in good condition, inflated properly, and have sufficient tread remaining.

13. Never exceed the 480 lbs (218 kg) maximum load rating.

14. The electric bike should never be used by children under the age of 18.

15. Maximum Speed - Your electric bike goes the maximum speed of 30+ mph.

16. Make note that additional insurance may be required to cover situations you encounter while riding an electric bike. It is recommended that you contact an insurance company or broker for advice and consultation.

17. To conserve electricity, use assist mode and avoid zero starting, frequent braking, driving against the wind, carrying heavy loads including other people and riding with insufficient air pressure.

18. Precautions for braking: Do not brake urgently. When the braking distance is long, first gently pinch the left brake to slow down, and then increase the force when approaching the target, gradually tightening the brake. If the braking distance is short and the speed is fast, the left and right brakes can be pinched together after deceleration.

19. Gear precautions: Confirm whether the gear is installed properly before starting. The contact of the gear should not deviate towards one end.

20. Precautions for Wet Weather: Do not ride under wet conditions. The electric bike may slide from under your feet causing injury. Wet conditions may damage the electronics and void the warranty.

21. Precautions for cycling at night: Be sure to turn on the front and tail lights when cycling at night.

22. Guidelines for Road Safety Operations: Obey traffic rules and do not drive in the wrong direction when driving on the road.

Your Real Inseam to fit this bike should be 25". How to Measure Real inseam (inside Leg Length): Wearing your regular riding shoes and with your back to the wall, stand with your feet spread so there is about 7 inches between them - this is about the distance apart your feet would be when straddling a bike with your feet on the ground (standover height).

Place a hardcover book against the wall with the spine of the book facing upward. Slide the book upwards towards your groin until it is solidly against your body. This may be a bit awkward, but it is way more comfortable -- and safer! -- than trying to ride a bike that is too big. If you have a buddy helping you, get them to measure from the floor to the top of the book spine while you hold the book in place. If you're going it alone, carefully hold the book in place and measure from the ground to the top of the book spine.

Assembly

Step 1: Front Wheel Installation

  1. Fix the vehicle body and remove the front fork protection rod using the wrench in the accessory tool.
  2. Remove the rubber plug on the disc brake and place the front wheel on the front fork (note that the disc is on the left side of the front fork).
  3. Remove the nut, safety hook gasket and spring of the front wheel quick release in sequence. Pass the front wheel quick release rod through the front hub axle core hole from the disc brake disc side. Be careful not to move the safety hook gasket and spring in sequence.
  4. Then put the removed nut, safety hook gasket and spring together in turn, align the safety hook gaskets on the left and right sides with the round holes, and close the quick release handle with your palm or fingers. The locking force of the handle is 15-20kgf.cm to prevent the quick release from loosening during riding.

Step 2: Front Fender & Headlight Installation

  1. Use the Allen wrench and a wrench from the accessories kit, remove the screws and anti-skid nuts on the front fork hanger.
  2. Fix the headlight and front mudguard mounting ears with screws and anti-skid nuts and tighten them.
  3. Use the included Allen wrench to remove the screws on both sides of the front fork.
  4. Fix the mud plate left side support to the left side of the front fork with the screw, then tighten.
  5. Fix the mud plate right side support to the right side of the front fork with the screw, then tighten.

Step 3: Riser Installation

  1. Use the included 5# hexagonal wrench to remove the screws on the aluminum pan cover and remove the eight-piece aluminum casing.
  2. Put the seat tube onto the front fork vertical tube, unfold the folded seat tube, first use your thumb to lift the lock buckle upward without loosening it, then use your index finger to pull the seat tube outward to unfold it.
  3. Use the included 5# hexagonal wrench to tighten the aluminum cover screws, and use the included hexagonal wrench to fix the screws on both sides of the riser.
  4. Press down the riser lock handle to lock the folding device.

Step 4: Handlebar Installation

  1. Use the included 5# Allen wrench to remove the 4 screws and top cover of the riser.
  2. Align the center of the handlebar on the riser, make sure the left and right sides are symmetrical, fix the top cover with the screws, and tighten the four screws evenly.
  3. Adjust the front position.
  4. Use the included 5# hexagonal wrench to tighten the screws on both sides of the riser.

Step 5: Pedal Installation

  1. Find the pedals with "R" and "L" stickers on them.
  2. Gently screw the right pedal onto the right crank by hand, turn it clockwise, and then tighten the pedal with an open-end wrench.
  3. Gently screw the left pedal onto the left crank by hand, turn it counterclockwise, and then tighten the pedal with an open-end wrench.
  4. Check chain alignment by rotating the right pedal and crank two full revolutions toward the back of the bike (simulating pedaling). Observe the chain (make sure it passes smoothly through the rear cassette, derailleur and front sprocket).

Step 6: Seatpost Installation

  1. Hold the quick release handle with your hand and pull it outward to fully open it.
  2. Insert the seat tube into the hole in the frame's center tube. Adjust the saddle so that the seat tube's head tube is parallel to the frame's top tube.

Ensure the fender mounting hardware is properly secured if fitted with fenders. Ensure there are no cracks or holes in fenders. If installed, ensure the optional rear wheel lock is secured in the unlocked position and the key is removed before every ride.

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 of 50-100 mi (80-160 km) (depending on riding conditions such as total weight, riding characteristics and terrain). Regular inspections and tune-ups are particularly important for ensuring that your bike remains safe and fun to ride.

Tire inflation and Replacement

The Hunter employs 20X4.0" rubber tires with inner tubes. The tires are designed for durability and safety for regular cycling activities and need to be checked before each use for proper inflation and condition. Proper inflation, care, and timely replacement will help ensure that your bike's operational characteristics will be maintained, and unsafe conditions avoided.

Jasion recommends 35 PSI for the stock tires on the Jasion. 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, like those that come with bikes from Jasion, can and do 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 from Jasion 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 Jasion may void your warranty, create an unsafe riding condition, or damage to 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 www.jasionride.com or contact Jasion Support Team.
