IMPORTANT NOTES

• Read all instructions carefully before use.

• Keep the manual handy at all times.

• Some assembly required. Use correct tools for your safety.

• Do NOT use trainer for any other purpose than instructed.

• The trainer is manufactured to precise standards. Disassembling or rebuilding by
yourself will void the warranty.

WARNINGS

Use two-wheeled normal bikes only. Tandems cannot be used.

We strongly recommend you to replace your quick release skewer with the one supplied

in the kit. Also install the coupling protector cap onto the right side coupling of the trainer.

Otherwise the stability will not be guaranteed.

You can remove the coupling protector cap when your bike doesn't have quick release

system but hub nuts, and when you use your own quick release skewer at your own risk.

Remove all oils and moisture from the drive roller and the tire before use.

Make sure the center frame is securely locked to the U-frame before installing your bike.

Check the couplings supporting the rear hub for damage and cracks. Accidents may occur

from cracked or damaged couplings.

You should not use the left side knob bolt for tightening the wheel axle. This is for pre-

adjusting the wheel position to the exactly center of the drive roller only.

Holding the wheel securely must be done by the right side hub handle.

When using the trainer, place it on a at and level surface oor for safe training.

Do not over-tighten the hub handles. Overtightening may cause damage to the trainer or

your bicycle frame. The clamp handles should be a snug and secure t. Do NOT force!

Before use, make sure all bolts and nuts are securely fastened.

Keep away from small children, and keep hands and feet away from spinning rollers and

wheels at all times.

Open the legs fully, make sure the front fork support touches the center frame edge and

adjust the center frame to t your bike wheel base correctly to get maximum stability.

(Fig. A)

<Required Tools> • Hex Wrench: M4 / M5

• Spanner: 10mm

Open the frame support legs and t the rubber feet at the correct angle and depth so the base is in full

contact with the oor.

NOTE: If the both legs don't touch the oor at same time and if one side of leg is still being lifted

up slightly, pull up the leg upward strongly then place the trainer on the oor again.

Connecting the Extension Tube to the U-Frame.

Lay down the U-Frame horizontally.

Remove the lower preassembled part bolt, nut and collar on the U-Frame. Do NOT remove the upper part

bolt and nut.

Put the collar into the hole on the Extension Tube then connect to the U-Frame while making sure the

Lock Bracket is facing upper.

Once hook the lock to the upper part bolt then tighten all bolts.

NOTE: Hook the lock before tightening the

bolts. Otherwise, you won't be able to

lock the cetner frame.

Installing the VFS resistance unit to the frame.

Set the unit onto the black base plate on the Main

Frame, and tighten it rmly with the supplied two bolts.

NOTE: The uid resistance unit side with many

ns MUST be located on the right side of

the trainer. The opposite side contains

the ywheel and the magnetic resistance

system in its plastic housing.

Connecting the Front Fork Support to the Main Frame.

Loosen the Knob Bolt then slide the Extension Tune into the Center Frame.

Tighten the Knob Bolt temporally, you will adjust the position later.

(Fig. D)

NOTE: If you had removed the Extension Joint completely, insert

it to the Center Frame while making sure the inside hole is

aligned to the Joint's hole. The Knob Bolt compressed the

Extension Tube through these holes.

Open both couplings by turning the left side knob (Fig.F) and the right

side hub handle (Fig. G) anti-clockwise.

Do NOT overloosen the couplings, otherwise the knob or hub handle may

become unthreaded inside the frame.

NOTE: We suggest you do not need to move the left side coupling

away so much. It should be ne to move by the center of its

length (Fig. H), but it needs to be adjusted depends on the

hub width.

1

Insert the left side of the skewer (quick lever side) into the left side

coupling, and adjust the rotation of the coupling so the skewer lever

sits securely in the large cut-out (Fig. I).

This will prevent damage to the skewer during use.

Hold the bike rmly by hand and turn the right side hub handle clockwise until the coupling come into

contact with the right side skewer nut.

3

Remove the front wheel and insert the fork end to the fork clamping quick release skewer, then grab the

fork end temporally.

NOTE: You will adjust the wheel base later, so you don't need to x the foek end rmly in this

step.

5

Loosen the Knob Bolt on the Center Frame for adjusting the wheel base until the horizontal

bar of the Front Fork Support touches the Center Frame (see Fig. J), then tighten the Knob

Bolt rmly.

NOTE: Not touching the Front Fork Support and the Center Frame will disturb the

stability while using. Make sure they are touching each other before ride.

(Fig. J)

Apply the VFS resistance unit to the

tire by lifting up it temporally by hand

to know the wheel position.

If the tire touches either left or right

side plastic housing of the VFS unit

(see Fig. K), you must adjust the wheel

position again by operating both the

left knob and the right hub handle.

NOTE: Be sure that the left knob is

NOT for tightening the axle.

It is only for positioning the

wheel. Clamping wheel

securely must be done by

the right side hub handle.

(Fig. K)

At this point, stop tightening the hub handle and ensure that

both ends of the skewer are securely inserted into the couplings.

Finally turn the hub handle a maximum of two more turns to

ensure the bicycle is held rmly.

NOTE: Over-tightening the hub handle may cause

damage to either the trainer or your bicycle.

(Fig. L)

Push downward the VFS unit and turn the micro-adjust screw

located beneath the foot pedal at the rear of the trainer until the

rear tire is 2mm away from the drive roller. (see Fig. L & M)

Press down on the foot pedal to bring the drive roller into contact

with the rear tire (Fig. N).

If the tire is compressed more than 4mm by the roller, release

the foot pedal and loosen the micro-adjust knob until the tire is

compressed by 2 - 3mm when in contact with the drive roller.

!

WARNING: Over-compressing or too less com-pressing

the rear tire can cause premature tire wear and may

also cause damage to the drive roller.

Shim

!

The Mag unit side has 7 different levels of load force for replicating actual riding resistance. You can set your preferred

resistance level between high (H) and low (L) by adjusting the lever on the thumb shifter type remote lever device (see

Fig. R).

You may also adjust the load force by shifting up or down among your gears, depend-

ing on the level desired.

NOTE: We recommend that you start with a medium to low load force and

gradually work up, increasing force as your muscles warm up.

How To Install The Remote Lever

You can install the remote lever on anywhere the diameter is between 22.2mm (7/8”) and 31.8mm (1-1/4”) like as on the

handlebar.

Using The Mag Resistance Unit

Fully loosen the knob bolt on the plastic holder until it stops then push down the bolt to open the holder. (Fig. O)

Place the holder onto the handlebar, shut the holder, and pull up the bolt then tighten it. (see Fig. P)

(Fig. Q)

When you install the shim on the plastic holder, make sure the direction of the shim as shown in Fig. Q.

Depending on the diameter of your handlebar, you must adjust the shim as follows;

• 22.2mm (7/8”) - 25.4mm (1”) : ...Install both shims

• 28.6mm (1-1/8”) : ...Install either right or left side shim

• 31.8mm (1-1/4”) : ...Remove both shims

(Fig. R)

Using The Small Wheel Adapter

<Required Tools> • M5 hex wrench

• 10mm open spanner)

If you wish to use any smaller wheel sized between 24 x 1.0" and 26 x 1.75" on the trainer, install the supplied Z-shaped

Adapter under the VFS unit. (Fig. S)

Remove two bolts which hold the VFS unit on the base plate by an M5 hex wrench. Then the VFS unit will be

removed.

Base Plate

Adapter

Install the supplied adapter on the base plate with the removed bolts. Make sure the direction of the adapter is

exactly same as shown in Fig. S. (Also printed on the top of the adaptor)

Wrong direction will set the VFS unit too close to the wheel and you cannot set the bike correctly.

Install the VFS unit onto the adapter with the supplied hex head bolts.

Be sure you should use a 10mm open spanner to tighten these bolts, not by a hex wrench.
