FULLY CHARGE BATTERIES BEFORE FIRST USE

  • Batteries should be fully charged immediately when they are received and immediately after each use for the recommended charge times (see below).
    • Li-lon (Lithium lon) batteries 4-6 hours.
    • For your personal and property safety, if no one is vigilant, please don’t charge the battery indoors.
  • We recommend that you consult a bicycle specialist if you have doubts or concerns as to your experience or ability to properly assembly, repair, or maintain your bicycle.
  • Additional warning/cautions are in the assembly section of this manual.
  • With proper care and maintenance Electric Bicycle will provide ease of use and be fun to ride. Below are points that will help you to maximize the enjoyment you get from your new hybrid electric bicycle.

FACTORS TO MAXIMIZE THE RANGE OF YOUR ELECTRIC BICYCLE

  • Rider input – the more the rider pedals the further the distance traveled. Continuous riding, as opposed to frequent stopping and starting, will yield the greatest range possible
  • Elevation Gain – the flatter the road the further the distance traveled
  • Weather – cold weather can adversely affect the battery capacity
  • Wind – traveling with a tailwind will increase distance traveled, traveling into a headwind will decrease distance traveled
  • Terrain – the smoother the terrain (roadways vs. fire roads, etc.) the further the distance traveled
  • Ride R Weight – the lighter the rider, resulting in less drain on the batteries, the further distance traveled
  • Bicycle Maintenance – a properly maintained bicycle will yield the greatest range possible
  • Tire Pressure – properly inflated tires have less rolling resistance and will be easier to pedal
  • Batteries – properly charged and maintained batteries will yield the greatest range possible. Batteries stored in cold areas (below 50 degrees Fahrenheit /10 degrees Celsius) will show reduced range.
  • Batteries that have not been kept in optimum condition will show reduced range and run time.

HELMETS SAVE LIVES!!!

  • ALWAYS WEAR A PROPERLY FITTED HELMET WHEN YOU RIDE YOUR BICYCLE.
  • DO NOT RIDE AT NIGHT.
  • CPSC RECORDS SHOW THAT ABOUT 35% OF BICYCLE RELATED DEATHS OCCUR AFTER DARK. AVOID RIDING IN WET CONDITIONS.
  • CPSC RECORDS SHOW THAT ABOUT 65% OF INJURIES HAPPEN TO CHILDREN UNDER 15 YEARS OF AGE, RIDE ONLY WITH ADULT SUPERVISION. FOR YOUR SAFETY, WHEN RIDING,
  • PLEASE WEAR A HELMET AND PROTECTIVE GEAR, AND PLEASE OBEY LOCAL LAWS AND REGULATIONS.

CORRECT FITTING. MAKE SURE YOUR HELMET COVERS YOUR FOREHEAD.

INCORRECT FITTING. FOREHEAD IS EXPOSED AND VULNERABLE TO SERIOUS INJURY.

Throttles
Throttles are equipped on some models of electric bicycles. Throttles operate by rotating the throttle towards the rider much like a motorcycle. They generally are the inner half of the right side handlebar grip and may also contain a battery gauge. The more you twist the throttle, the faster the motor system will propel the bicycle.
TAG(Twist and Go)

  • Before you begin riding, turn the main power switch on, then start riding as you would ride any regular, non motor assisted bicycle. After you have begun to ride, slowly twist the throttle (on equipped models) towards you. The more you twist the throttle, the more motor power will be applied to the wheels. You may feel the pedals get a “lighter” feel than when riding without the motor assisting you.
    13-30mph (20-48km/h) Varies according to load changes.

  • Begin by first riding as if you are on a normal non-electric bicycle. After a few seconds, the motor will slowly activate and ramp up to 50% power. Then, while the pedals are in motion, you can slowly  twist the throttle towards you to activate the full motor power.

Battery Care and Information

  • Proper maintenance of batteries will maximize their lifespan and capacity. JANSNO X50 warranties your new batteries from the date of purchase only if properly cared for-refer to the limited warranty for details.
  • Ruli use Li-lon (Lithium lon) batteries in all of our electric bicycles and scooters.
  • These are both very user-friendly types of batteries when cared for properly.

Care

  • Even with proper care, rechargeable batteries do not last forever. Every time the battery is discharged and subsequently recharged, its relative capacity decreases by a small percentage. You can maximize the life of your battery by following the instructions in this guide.
    • Batteries should be fully charged immediately when they are received for the full recommended charge times. Li-lon recommended charge time: 4-6 hours For a complete, 100% charge, leave the battery on the charger for one full hour after the charger indicator light turns green.
    • Never charge batteries for longer than 24 hours.
    • Li-lon batteries do not have a “memory.” Partial discharge/charge cycles will not harm the batterie’s capacity or performance.
    • The rated output capacity of a battery is measured at 77°F(25°℃). Any variation in this temperature will alter the performance of the battery, and shorten its expected life. High temperatures especially reduce overall battery life & run time.
    • Be friendly to the environment! Be sure to recycled your old batteries at a local battery-recycling center. Do not throw them in the garbage!
    • Do not charge the battery indoors!
  • Thank you to provide us with valuable suggestions. When maintaining and repairing your vehicle, give us your valuable suggestion card together with the after-sale card. We will listen to your suggestions actively and modify our deficiencies in time.

BIKE ASSEMBLY MANUAL

Bicycle Assembly

  • Assembly Guides
    • Individual assembly guides for each bicycle model can be found packaged with your bicycle.
  • Getting Started
    • Open the carton from the top and remove the bicycle. Remove the straps and protective wrapping from the bicycle. Inspect the bicycle and all accessories and parts for possible shortages. It is recommended that the threads and all moving parts in the parts package be lubricated prior to installation. Do not discard packing materials until assembly is complete to insure that no required parts are accidentally discarded.
  • Note: Your bicycle may be equipped with different style components than the ones illustrated.

Pedals & Crank Set
Look for the letters “R” for right, and “L” for left, stamped on each pedal spindle. Start threading each pedal by hand to avoid stripping the threads. Tighten with a 15mm narrow open ended wrench. Note that the right hand pedal attaches to the chainwheel side crank arm with a right-hand (clockwise) thread. The left pedal attaches to the other crank arm and has a left-hand (counter-clockwise) thread. It is very important that you check the crank set for correct adjustment and tightness before riding your bicycle. New cranks may become loose with initial use. Once the pedals have been installed, remove the dust caps from the center of each crank arm. Tighten the spindle nuts securely (approx. 350 in. Ibs.) with a 14mm socket wrench or an 8mm Allen wrench, depending on style, then replace the dust caps.

Attachment of an incorrect pedal into a crank arm can strip pedal threads and cause irreparable damage. Before your first ride, please check to insure your pedals are attached correctly.

  • securely clamping the wheel takes considerable force. If you can fully close the quick release without wrapping your fingers around the fork blade for leverage, and the lever does not leave a clear imprint in the palm of your hand, the tension is insufficient. Open the lever; turn the tension adjusting nut clockwise a quarter turn; then try again.
  •  If the lever cannot be pushed all the way to a position parallel to the fork blade, return the lever to the OPEN position. Then turn the tension adjusting nut counterclockwise one-quarter turn and try tightening the lever again.
  • Re-engage the brake to restore correct brake pad-to-rim clearance; spin the wheel to make sure that it is centered in the frame and clears the brake pads; then squeeze the brake lever and make sure that the brakes are operating correctly.

Front Wheel-Bolt-installation

  1. Make sure the brakes are loose enough to allow the wheel to pass through the brake pads easily.
  2. Place wheel into fork dropouts.
  3. Install retaining washers with raised lip pointed towards the fork, and insert into the small hole of the fork blade. NOTE: Some bikes may have step retaining washers in place of the retaining washer (shown in dotted box). If so, install the step retaining washer, raised portion sliding in to the fork dropouts.
  4. Install axle nut and tighten. Make sure the wheel is centered between the fork blades.
  5. Spin the wheel to make sure that it is centered and the clears brake shoes. Tighten the brakes if necessary.
    It is very important to check the front wheel connection to the bicycle. Failure to properly tighten may cause the front wheel to dislodge.JANSNO-
Electric-Bike-20-4-0-Electric-Bike-for-Adults- \(25\)

Rear Wheel-Bolt-on installation

  1. If the bicycle has rim brakes, make sure the brakes are loose enough to allow the wheel to pass through the brake pads easily. For disc brakes, no adjustment is required.
  2. Place the wheel into frame dropouts.
  3. Slide a washer onto each side of the axle.
  4. Install axle nuts and tighten. Make sure the wheel is centered in the frame. This may be easiest with the bike turned upside-down.
  5. Spin the wheel to make sure that it is centered and clears the brake shoes. Tighten the brakes if necessary.
  • Tighten both rear wheel axle nuts securely. Failure to do this may cause the rear wheel to dislodge from the frame dropouts resulting in serious damage or injury.
  • Periodically, disassemble the mechanism from the bicycle and inspect for any wear or damage and replace if necessary. = When reinstalling, it is very important to ensure the connections are made properly.

Rear Wheel-Bolt-on Removal

  1. If the bicycle has rim brakes, make sure the brakes are loose enough to allow the wheel to pass through the brake pads easily. For disc brakes, no adjustment is required.
  2. Most bikes have a plug or quick-disconnect box located on the seat stay or chain stay. These allow the motor to be easily disconnected from the controller. Simply undo the single large plug or open the black plastic box and undo the five plugs inside.
  3. With the bicycle in a stand or upside-down, loosen the axle nuts then remove the wheel from the bicycle.

Disc Brakes – Tektro

  1. Check the tightness of the six disc mounting bolts holding the brake rotor onto the wheel. If you need to remove these bolts, be sure to us a thread-locking compound when re-installing them.
  2. Make sure the two bolts securing the caliper adaptor bracket to the fork are tight.
  3. Thread the brake cable through the caliper as shown and secure it with the cable fixing bolt.
  4. Loosen the two caliper mounting bolts enough to allow the brake caliper to float freely.
  5. Install the wheel, making sure the brake rotor fits into the slot in the caliper. Center the caliper around the brake rotor, then tighten the caliper mounting boits.
  6. Using the inner pad adjusting bolt, adjust the inside brake pad so it is as cose as possible to the rotor without rubbing.
  7. Using the caliper barrel adjustor, adjust the outside brake pad so it is as close as possible to the rotor without rubbing.

Brake rotors get hot! Severe injury could result from contact with the hot rotor. Mind your legs, as well as your hands.

  • Disc brakes require breaking in. Ride and use the brakes gently for about 13 miles before using the brakes in downhill conditions, for sudden stops or any other serious braking. Please be aware that your brake system will change in performance throughout the wear in process. The disc brake should be cleaned before the first ride using rubbing alcohol. NEVER use oil or similar products to clean your disc brake system.
  • Avoid touching the rotor (disc) with your fingers at any time. naturally oily fingers can contaminate the rotor and/or the brake pads and diminish the brake’s effectiveness.
  • DERAILLEUR SYSTEMS
    • The derailleur system includes the font and rear derailleurs, the shift levers, and the derailleur control cables, all of which must function correctly for smooth gear shifting to occur.
  • Derailleur
    • Although the front and rear derailleurs are initially adjusted at the factory, you will need to inspect and readjust both before riding the bicycle.
  • Rear Derailleur
    • Begin by shifting the rear shifter to largest number indicated, loosen the cable from the rear derailleur cable anchor bolt, and place the chain on the smallest sprocket.
    • Adjust the High limit screw so the guide pulley and the smallest sprocket are lined up vertically. Re-tighten the cable, pull out any slack, and retighten the anchor bolt securely. Shift through the gears, making sure each gear achieved is done quietly and without hesitation. If necessary, use the barrel adjuster to fine tune the cable tension by turning it the direction you want the chain to go.
    • For example, turning clockwise will loosen the cable tension and move the chain away from the wheel, while turning counter-clockwise will tighten cable tension and direct the chain towards the wheel. JANSNO-Electric-Bike-20-4-0-Electric-Bike-for-Adults- \(32\)

Final Check

  • After all adjustments have been made, shift through every gear several times at varying speeds. This will ensure all your adjustments are correct and will allow you to pinpoint any trouble areas. If you encounter any problems, refer to the appropriate section and make any necessary adjustments.
  • Check the tire pressure and inflate each tube to the recommended psi as stated on the sidewall of the tire.
  • Check that the kickstand operates smoothly and the kickstand bolt is secured tightly.
  • Finally, examine the bicycle. Make sure all accessories are attached and all quick releases, nuts and bolts have been tightened securely.
  • Correct maintenance of your bicycle will ensure many years of happy riding. Service your bicycle regularly by referring to the relevant sections of this manual, OR take it to a professional bicycle shop.
  •   Remember : Always wear a helmet and obey all traffic laws.JANSNO-Electric-Bike-20-4-0-Electric-Bike-for-Adults- \(33\)
  • Never inflate a tire beyond the maximum pressure marked on the tire’s sidewall. Exceeding the recommended pressure may blow the tire off the rim, which could cause damage to the bicycle and injury to the rider and bystanders.
  • Tighten both rear wheel axle nuts or the quick release mechanism securely. Failure to do this may cause the rear wheel to dislodge from the frame dropouts resulting in serious damage or injury.

Correct routine maintenance of your new bike will ensure smooth running Longer lasting components-Safer riding-Lower running costs

Every time you ride your bicycle, its condition changes. The more you ride, the more frequently maintenance will be required. We recommend you spend a little time on regular maintenance tasks. You should be able to accomplish most tasks. If you require assistance, we recommend you see a bicycle specialist.
