ADJUSTMENT GUIDE
ADJUSTING THE BALANCE:
In order 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. 12) to loosen the Nut (No.
3) by turning it clockwise (direction A). With the nut loosened, rotate the
Foot Pad (No. 4) until it sits level with the surface that the bike is on.
When you have finished adjusting the foot pad, re-tighten the Nut (No.
3) by turning it counter-clockwise (direction B) using Spanner (No. 12). If
required, repeat this process to adjust the remaining foot pads.
RESISTANCE & BRAKING:
You may adjust the tension level of the bike by rotating the Tension
Control Knob (No. 71). To increase the level of resistance, rotate the
control knob clockwise,to decrease the level of resistance, rotate the
control knob counter-clockwise.
During an exercise, users may stop the bike immediately by pushing
down on the Brake Handle (No. 69). This is the emergency brake.
ADJUSTING THE HANDLEBAR:
It is important that the handlebar and seat are both set to the correct
height of your body. To adjust the handlebar height, loosen and pull the
Adjustment Knob (No. 20) outward, then slide the Handlebar Post
(No. 22)up or down to the desired height. Once adjusted re-insert and
tighten the Adjustment Knob (No. 20) to secure the handlebar post in
place
TRANSPORTING THE BIKE:
To move the bike, first ensure that the Handlebar (No. 23) is properly
secured. If the handlebar is loose, tighten the Adjustment Knob (No.
20)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, place one foot on the front stabilizer and tilt the bike towards
you until the transportation wheels on the front stabilizer touch the
ground. With the wheels on the ground, you can transport the bike to the
desired location with ease.
NOTE: When moving the bike, always use caution as unexpected
impact, such as dropping the bike, may cause injury and affect the
bike’s performance.

MAINTENANCE INSTRUCTIONS
This is general information for daily, weekly and monthly maintenance to be performed on
your bike.
Version 2.1
Version 1.3
DAILY MAINTENANCE
After each exercise session, wipe down all
the equipment: seat, frame, 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 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 build up of
foreign material.
WEEKLY MAINTENANCE
1. Inspect moving parts and tighten the
hardware.
2. Inspect pull pin frame fittings, making
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, making 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.
Version 2.2
