ADJUSTMENTS AND USAGE GUIDE

ADJUSTING THE HEIGHT AND BALANCE

In order to achieve a smooth and comfortable ride, you must ensure that the stability of the bike is secured. If you notice that the bike is unbalanced during use, adjust the Adjustment Foot Pad (No. 37), located beneath the Front & Rear Stabilizers (No. 5 & No. 6) of the bike. To do so, use Wrench (No. 96) to loosen Hex Thin Nut (No. 76) by turning it clockwise (direction A). With the nut loosened, rotate the Adjustment Foot Pad (No. 37) until it sits level with the surface that the bike is on. When you have finished adjusting the Adjustment Foot Pad (No. 37), re-tighten the Hex Thin Nut (No. 76) by turning it counter-clockwise (direction B) to complete the balance adjustment of the bike. If needed, repeat this process to adjust the remaining adjustment foot pad.

ADJUSTING THE RESISTANCE

Adjust the resistance of the bike using the Tension Control Knob (No. 21). Increase the level of resistance by turning the Tension Control Knob (No. 21) to the RIGHT (clockwise), decrease the level of resistance by turning the Tension Control Knob (No. 21) to the LEFT (counter-clockwise).

EMERGENCY BRAKE

During use, users can stop the bike completely by pushing down on the Tension Control Knob (No. 21). Pushing down on the Tension Control Knob (No. 21) will enforce the brake and bring the bike to an immediate stop.

ADJUSTING THE SEAT

The seat of this bike is fully adjustable as it moves Up, Down, Fore (forward), Aft (backward).

To adjust the height of Seat Post (No. 2), loosen and pull the Adjustment Knob (No. 22) outward, then raise or lower the seat to the desired height. Once adjusted, re-insert and tighten the Adjustment Knob (No. 22) to secure the Seat Post (No. 2) in place.

To adjust the seat back and forth, loosen and pull the Adjustment Knob (No. 22) outward, then slide the Seat Slider (No. 8) to desired position. Once positioned, re-insert and tighten the Adjustment Knob (No. 22) to secure the Seat Slider (No. 8) in place.

ADJUSTING THE HANDLEBAR

It is important that the handlebar and seat are both set to the correct height to your body. To adjust the handlebar height, loosen and pull the Adjustment Knob (No. 22) outward, then slide the Handlebar (No. 9) up or down to the desired height. Once adjusted, re-insert and tighten the Adjustment Knob (No. 22) to secure the handlebar in place.

PEDAL STRAP ADJUSTMENT

Your feet should be secured in the toe clips during exercise. Place your feet as far forward into the toe clips as you can. With your feet in place, turn the crank to bring one foot to within arm’s reach, grasp the pedal strap and pull it upward to tighten the toe clip cage. Then insert the strap back into the hoop of the toe clip. Repeat this process to secure your other foo

TRANSPORTING THE BIKE

To move the bike, first ensure that the Handlebar (No. 9) is properly secured. If the handlebar is loose, tighten the Adjustment Knob (No. 22) to secure it. Next, stand at the front of the bike so that you’re directly in front of the handlebar. Firmly grasp and hold each side of the Handlebar (No. 9), place one foot on the Front Stabilizer (No. 5), and tilt the bike towards you until the transportation wheels on the Front Stabilizer (No. 5) touch the ground. With the wheels on the ground, you can transport the bike to the desired location with ease.

NOTE: Always use caution when moving the bike. Unexpected impact, such as dropping the bike, may cause injury and affect the bike’s operation

DISMOUNTING

For your safety, it is recommended that you never attempt to dismount or remove your feet from the pedals until both the flywheel and pedals/cranks have come to a complete stop. Failure to follow this recommendation may lead to loss of control and/or serious injury.

Here are a few examples of how to safely dismount the bike:

Reduce the pedal speed until the pedals/cranks come to a complete stop.

1. Increase the resistance until the pedals/cranks come to a complete stop.
2. Push and hold the tension control knob down until the pedals/cranks come to a complete stop.

SPD TECHNICAL SERVICE INSTRUCTIONS

Caution!

Before use, read these instructions carefully.

• Practice engaging and disengaging from the pedals several times in a stationary position before riding.
• Before using, lubricate the concave area of the clip.
• Keep the cleat and pedal clean to ensure proper usage.
• Before using, adjust the retention force of the pedal to suit your needs.

Note:

1. After tightening the cleat, practice engaging and releasing one shoe at a time.
2. Check your pedals each time before you ride the bike.
3. When the pedal starts to wear on the axle, it will not function properly. We recommend you replace the entire pedal.

USE

ADJUSTING THE SPRING TENSION OF THE BINDING

The tension of the spring is adjusted for each pedal (top & bottom) with the adjustment bolt in the rear using a 3mm Allen Wrench.

Using a 3mm Allen Wrench, turn the bolt in a clockwise direction to increase retention force. Turn the bolt in a counter-clockwise direction to decrease retention force.

MAINTENANCE INSTRUCTIONS

This is general information for daily, weekly and monthly maintenance to be performed on your bike.

DAILY MAINTENANCE

After each exercise session, wipe down all the equipment: seat, frame, and handlebars. Pay special attention to the seat post, handlebar post and belt/chain guard. Sweat is very corrosive and may cause problems that require parts replacement later.

1. Get on the bike and engage the drive train.
2. Pay attention to any vibrations felt through the pedals. If you feel any vibrations, you may need to tighten the pedals, bottom bracket, or adjust the drive belt/chain tension.
3. Use a wrench to tighten the pedals until they are secure.

MONTHLY MAINTENANCE

1. Check if all hardware is secure, such as: water bottle holder, flywheel nuts, belt/chain guard bolts, brake caliper lock nuts, and brake caliper tension rod nuts.
2. Inspect the brake tension rod for signs of wear such as missing threads. Clean and lubricate the brake tension rod.
3. Clean and lubricate the seat post, handlebar post and seat slider. Remove any buildup of foreign material.

WEEKLY MAINTENANCE

1. Inspect moving parts and tighten the hardware.
2. Inspect pull pin frame fittings to make sure the fittings are snug. Loose frame fittings may strip out threads over time and cause extensive damage.
3. Clean and lubricate pop pin assemblies. Pull on the pin and spray a small amount of lubricant onto the shaft.
4. Tighten the seat hardware to make sure the seat is level and centered.
5. Brush and treat the resistance pads. Remove any foreign material that may have collected on the pads. Spray the pads with silicone lubricant. This helps to reduce noise from friction between the pads and the flywheel.
6. Visually inspect the bottom bracket, toe clips and toe straps. If any of them are loose or disconnected, attach and tighten.

LEATHER BRAKE PAD CARE (If applicable)

1. Perform this maintenance when the brake pad is first installed and for the life of the brake pad. Following these simple guidelines can increase the life of your brake pads.
2. Some brake pad assemblies are pre-lubricated. Squeeze the brake pad. If lubricant is released, then the pad has been pre-lubricated.
3. If the brake pad is dry, then coat the brake pad with 3-n-1 oil. Brush the leather with a clean, wire bristle brush, and then apply the oil. The oil should be allowed to soak into the pad. Repeat 4-5 times until the pad is saturated, but not dripping with oil. When the pad is saturated, it will no longer absorb oil.
4. Inspect the brake pad weekly and lubricate if needed. The pad should not have a glazed appearance. If the pad appears glazed, then brush it with wire brush and apply lubricant as needed. If any of the sponge padding is showing through the leather pad, the brake pad should be replaced.
