ADJUSTMENTS & USAGE GUIDE

| ADJUSTING THE BALANCE
In order to achieve a smooth and comfortable ride, you must ensure that the bike is stabled and secured. If you notice that the bike is unbalanced during use, you should adjust the Foot Levelers (No. 13) located beneath the Front & Rear Stabilizers (No. 7 & No. 6) of the bike. To do so, use Spanner (No. 95) to loosen Nut (No. 66) by turning it clockwise (direction A). With the nut loosened, rotate the Foot Leveler (No. 13) until the bike becomes levelled with the floor surface. When you have finished adjusting the Foot Leveler (No. 13), re-tighten the Nut (No. 66) by turning it counter-clockwise (direction B) to complete the balance adjustment of the bike. If required, repeat this process to adjust the remaining the Foot Levelers (No. 13).
---|---
| ADJUSTING THE TENSION & EMERGENCY STOP
Adjust the tension by rotating the Tension Control Knob (No. 32) clockwise to increase the level of resistance. Rotate the Tension Control Knob (No. 32) counter-clockwise to decrease the level of resistance. Push
down on the Tension Control Knob (No. 32) to enforce the brake and stop the bike immediately.
| ADJUSTING THE ANGLE OF SEAT
Use Spanner (No. 94) to unscrew the nut under the seat. Adjust the seat to the desired angle and reinstall the nut. Check the nut periodically to ensure that it is tight and secure. Use the Spanner (No. 94) to tighten when necessary. Note: You will need to tighten the nut on the opposite side at the same time. The use of an additional spanner is required.
**| MOVING THE BIKE
To move the bike, first ensure that the Handlebar (A) (No. 41) is properly secured. If the Handlebar (A) (No. 41) is loose, tighten the Adjustment Knob (No. 4) to secure it. Next, stand in front of the bike so that you’re
directly in front of the Handlebar (A) (No. 41). Firmly grasp and hold each side of the Handlebar (A) (No. 41), place one foot on the Front Stabilizer (No. 7), and tilt the bike towards you until the Transportation Wheels (No.
12) on the Front Stabilizer (No. 7) touches the ground. With the Transportation Wheels (No. 12) on the ground, you can transport the bike to the desired location with ease.
| ADJUSTING THE HEIGHT**
Loosen and pull out the [seat height] Adjustment Knob (No. 4) to adjust the height of the seat. You may also slide the seat forward or backwards by loosening and pulling out the [seat] Adjustment Knob (No. 4) on the Seat
Slider (No. 3). You may adjust the height of the handlebar by using the [handlebar] Adjustment Knob (No. 4). When adjusting, you will see a limit on the seat post, seat slider, and handlebar post. Do not lift the posts
passed this mark. Always check the Adjustment Knob (No. 4) to ensure that it is fully secured when you finish making an adjustment.

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: 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 built up 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 secure. 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 in to 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.
