Safe Cycling and Safety Tips

Pre-Ride Check Points

Before you ride your pedal electric assistance bicycle always make sure it is in a safe operating condition. Particularly check that your:

• Nuts, bolts, quick-release and parts are fastened tight, not worn, or damaged.
• Riding position is comfortable and unencumbered.
• Brakes are operating effectively.
• Steering is free with no excessive play.
• Wheels run true and hub bearings are correctly adjusted.
• Wheels are properly secured and locked to frame/fork.
• Tires are in good condition and inflated to correct pressure (tire pressure in on tire sidewall - do not exceed max tire pressure).
• Pedals are securely tightened to pedal cranks.
• All reflectors are in position and secure.

After you have made any adjustment to your electric bicycle, check that all nuts and bolts are securely tightened and cables are free from kinks and fixed securely to the electric bicycles frame. Every six months, your electric bicycle should be professionally checked to ensure that it is in correct and safe working order. It is the responsibility of the rider to ensure all parts are in good working order.

What Never To Do When Riding

• NEVER ride without wearing an approved helmet, which must meet USA/European (CPSC/EN) standards. Always comply with the local laws and ordinances.
• NEVER ride on the same side of the road as oncoming traffic.
• NEVER carry a passenger, this bicycle is designed for a single rider only.
• NEVER hang item(s) over the handlebars, this could interfere with steering or catch in the front wheel causing a crash.
• NEVER hold on to another motor vehicle or bicycle.
• NEVER ride too close to another vehicle - keep your distance and awareness.

Wet Weather Riding: Your bike's brakes do not work as well under wet or icy conditions as they do under dry conditions. The braking distance in wet weather will be longer than that in dry conditions. Take special precautions in wet weather to assure safe stopping. Ride slower than normal and apply your brakes well in advance of anticipated stops.

Night Riding: Do not ride at night. If you have to be on your e-bike at night or in low-light conditions, always comply with laws and regulations (local and otherwise) for bicycle lighting. Use approved headlights (white), taillights (red) properly affixed to your e-bike in addition to all-around reflectors. For additional safety, wear light colored clothing with reflective stripes, or safety yellow or safety orange clothing. Check that the reflectors are firmly secured in the correct position and clean and not obscured. Damaged reflectors must be replaced immediately.

Routine Maintenance & Check and Lubrication

As with all mechanical components, your bicycle is subjected to wear and stress. Different materials and components may react to wear or fatigue in different ways. If the design life of a component has been exceeded it may suddenly fail, possibly causing injuries to the rider. Any types of cracks, scratches, or change of coloring in highly stressed areas indicate that the life of the component has been reached and it should be replaced immediately. Always inspect your bicycle before every ride.

Assembly Instruction

This bikes comes assembled- no tools required for assembly. We strongly recommend you take this bike to a professional bicycle shop for adjustment and education on its operation and maintenance.

Unfolding Your Bike And Connecting The Frame

1. Your bike comes folded. Unfold the frame and swing the two hinged halves until they almost come together - this may require extra effort as the parts are new.
2. You will need to pull up on the quick release latch (Fig. 3) to allow the two frame halves to mate against one another.
   
3. Once the halves are together, release the quick release latch so it locks (Fig.4).
   
4. Swing the quick release latch around so it fits fully in the slot in the hinge on the front half of the frame. Make sure the steel and nylon washers are on the outside of the hinge and against the lever body (Fig.5)
   
5. Close the quick release lever to complete attaching the two halves of the frame (Fig.6 & 7).
   
   The lever should require some effort to close. If the lever is too difficult to close, or closes with little effort, tighten or loosen the nut on the end of the latch to adjust the lever tension (Fig.5).

Connecting The Handlebar To The Stem

1. Swing the handlebar assembly into place by rotating upwards (Fig.8).
   
2. Once the handlebars are in the upright position, lock into place by pressing the lever to the handlebar mast (Fig.9).
   

Unfold Pedals

1. Unfold the pedals by simply applying pressure to pull them in the riding position.
   You will hear a click when they lock into position. (Fig. 10 & 11)
   

Check Pedal Tightness

1. Pedals need to be checked for tightness.
2. Use the 15mm portion of the included multi-wrench, your own 15mm open end wrench, or adjustable wrench.
3. The right side pedal tightens clockwise (Fig.12).
   
   The left side pedal tightens counterclockwise (Fig.13).
   
   The pedals need to be tightened with a considerable amount of force so that they do not come lose. Pedal side is determined when you sit on bike.

Adjust Seat Height

1. To adjust the seat height, pull the quick release lever attached to the top of the seat tube outwards and adjust the seat to your desired height.
2. Once you have adjusted the seat post to your desired height, lock it in place by closing the quick release lever against the clamp (Fig.14).
   
   The lever should require some force to close. If it closes too easily and does not hold or if the effort to close the clamp is too great, adjust the clamping force by loosening or tightening the adjusting nut on the side opposite the lever.

Your seat post is extra-long to fit a variety of rider sizes to the compact, folding frame design. Check the seat post closely. It has upper limit line marked on rear of seatpost (how low your seat can go), and lower limit line (how high your seat can go) marked on the front of the seatpost.

Lower Limit Line: Never adjust the seat height so that the limit line at the lower end of the seat post is showing outside of the frame (Fig.15).

Lower Limit Line

Upper Limit Line: Always adjust the seat height so that the limit line at the upper end of the seat post is showing outside of the frame (Fig.16).

Upper Limit Line

Using the bike with the minimum insertion line on the lower portion of the seat post showing above the frame could result in a failure of the seat post and/or the frame causing a loss of control with potential injury to rider. Such failures are not covered by warranty as it is improper use of the product.

Check Tire Inflation & Installation

1. Locate the tire manufacturer's recommended inflation pressure found on the tire sidewall (listed as "PSI").
2. Using a hand or floor pump with a gauge, begin to inflate the tire to half its recommended inflation pressure and check to see that the tire is properly seated on the rim. Be sure to inspect both sides of the tire for proper fit.
3. If the tire is seated unevenly or bulges out along the rim, let some air out of the tire and reposition the tire by hand so that it sits evenly on the rim.
4. Continue to inflate the tire to the manufacturer's recommended pressure.
5. Do not exceed the recommended pressure as this will cause an unsafe condition potentially causing the tire to unexpectedly explode.
6. Do not use a compressed air device to inflate your tires as the rapid inflation of the tire can cause it to blow off the rim.
7. Tires and tubes are not warranted against damage caused by over-inflation or punctures from road hazards.

Check Handlebar Stem Alignment

1. Sit on your bike - check to make sure the handlebar stem and fork are in-line with one another.
2. If it is all good (Fig.20),
   
   you are done. Otherwise, do the following:
   1. Unfold the handlebar (Fig.17).
      
   2. With 5mm hex wrench loosen the Compression Cap – the top center bolt in the stem (Fig.18).
      
   3. With the same 5mm hex wrench, loosen the two Stem Binder Bolts on side of stem these hold the stem to the fork. Loosen just enough so you can move/adjust the stem and center it in line with the front tire (Fig.19).
      
   4. Line up the handlebar/stem with the front tire (Fig.20).
   5. Reverse the process:
      1. Tighten the top center bolt in the Compression cap of the stem (Fig.18).
      2. Tighten the two Stem Binder Bolts on the side of the stem (Fig.19).

Adjust Handlebar Height

1. To adjust the handlebar height, pull the quick release lever attached to the top of the stem mast outwards and adjust the handlebar to your desired height.
2. Once you have adjusted the handlebar to your desired height, lock it in place by closing the quick release lever against the clamp (Fig.21).
   
   The lever should require some force to close. If it closes too easily and does not hold the seat post in place, or if the effort to close the clamp is too great, adjust the clamping force by loosening or tightening the adjusting nut on the side opposite the lever.

Never adjust the handlebar height so that the limit line at the lower end of the seat post is showing outside of the frame (Fig.21).

Before Your First Ride

We strongly recommend you take your bike to a professional bike shop and have them check your work and fine tune the bike to ensure your bike is safe to ride.

Serial Number

It is important that you locate and record the serial number of your bicycle in case of a recall or if the bicycle is stolen. The serial number can be found under the crank bottom bracket stamped into the frame (Fig.22).

Electrical Components Operation, Maintenance, & Safety

The e-bike in this manual features "Start Aid". This electric assistance system will help riders save their energy when starting the bike rolling.

How Start Aid Works: When pressing the Start Aid button, the bike can be started at a speed of ~3.5MPH (6km/h). When the bike starts moving forward, start to pedal and release the "Start Aid" button.
