ADJUSTMENT GUIDE 

	ADJUSTING THE BALANCE: To achieve a smooth and comfortable ride during use, you must ensure the stability of the bike. If you notice that the bike is unbalanced, you can adjust the foot pads located beneath the front and rear stabilizers. To do so, use the Spanner (No. 88) to loosen the Hex Nut (No. 49) by turning it CLOCKWISE (direction A). With the Hex Nut (No. 49) loosened, rotate the Foot Pad (No. 16) until it sits level with the surface that the bike is on. When you have finished adjusting the Foot Pad (No. 16), re-tighten the Hex Nut (No. 49) by turning it COUNTER-CLOCKWISE (direction B) using Spanner (No. 88). If required, repeat this process to adjust the remaining Foot Pads (No. 16).
	RESISTANCE AND BRAKING:   You may adjust the tension level of the bike by rotating the Tension Knob (No. 11). To increase the level of resistance, rotate the Tension Knob (No. 11) CLOCKWISE. To decrease the level of resistance, rotate the Tension Knob (No. 11) COUNTER­ CLOCKWISE.   During exercise, you may stop the bike immediately by pushing down on the Brake Lever (No. 9). This is the emergency brake.
	ADJUSTING THE HANDLEBAR:   The handlebar and seat must be both set to the correct height of your body. To adjust the handlebar height, loosen and pull the Adjustment Knob (No. 23) outward, then slide the Handlebar Post (No. 4) up or down to the desired height. Once adjusted, re­ insert and tighten the Adjustment Knob (No. 23) to secure the Handlebar Post (No. 4) in place.
	TRANSPORTING THE BIKE:   To move the bike, first ensure that the Handlebar (No. 5) is properly secured. If the Handlebar (No. 5) is loose, tighten the Adjustment Knob (No. 23) to secure it. Next, stand at the front of the bike so that you’re directly in front of the Handlebar (No. 5). Firmly grasp and hold each side of the Handlebar (No. 5), place one foot on the Front Stabilizer (No. 8) and tilt the bike towards you until the Transportation Wheels (No. 21) on the Front Stabilizer (No. 8) touch the ground. With the Transportation Wheels (No. 21) on the ground, you can transport the bike to the desired location with ease.   NOTE: When moving the bike, always use caution as unexpected impacts, such as dropping the bike, may cause injury and affect the bike’s performance.

	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 Belt (No. 62) and pull it upward to tighten the Toeclip Cage (No. 61). Next, insert the Pedal Belt (No. 62) back into the hoop of the toeclip. Repeat this process to secure your other foot.
	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 the Seat Post (No. 2), loosen and pull the [seat post] Adjustment Knob (No. 23) outward, then raise or lower the seat to the desired height. Once adjusted, re-insert and tighten the [seat post] Adjustment Knob (No. 23) to secure the Seat Post (No. 2) in place.   To adjust the seat back and forth, loosen and pull [seat slider] Adjustment Knob (No. 23) outward, then slide the Seat Slider (No. 3) to the desired position. Once positioned, re-insert and tighten the [seat slider] Adjustment Knob (No. 23) to secure the Seat Slider (No. 3) tube in place.
	TIGHTENING THE SEAT   Please adjust the Hexagon Nuts by using the Wrench (No. 87) if the Seat (No. 22) is loose.
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. Increase the resistance until the pedals/cranks come to a complete stop. Push and hold the tension control knob down until the pedals/cranks come to a complete stop.

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

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

WEEKLY MAINTENANCE   Inspect moving parts and tighten the hardware. Inspect pull pin frame fittings, making sure the fittings are snug. Loose frame fittings may strip out threads over time and cause extensive damage. Clean and lubricate pop pin assemblies. Pull on the pin and spray a small amount of lubricant onto the shaft. Tighten the seat hardware, making sure the seat is level and centred. Brush and treat the resistance pads. Remove any foreign material that may have been collected on the pads. Spray the pads with silicone lubricant. This helps to reduce noise from friction between the pads and the flywheel. 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)   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. Some brake pad assemblies are pre-lubricated. Squeeze the brake pad. If lubricant is released, then the pad has been pre-lubricated. 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. 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 a 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.
