VFS150
Read this instructions carefully before use
(Image: VFS150 non-remote type)

IMPORTANT NOTICE
• For use with a normal 2-wheel bicycle only. Do not use a tandem, recumbent, or other.
• Use the supplied rear quick release skewer for maximum stability when your bike is
equipped with a quick release skewer on the rear wheel.
Minoura is not responsible for any problem caused from using your own skewer.
• Hub nut type rear wheel axle is also compatible with VFS150 in standard.
Remove the F-9 Grommet (Hub Nut Protector) from the Right Side Coupling (F-1) for
better stability.
• Fits wheel size between 24" and 27"/700c. To use 26x1.75" or smaller wheel, install
the supplied Z-shaped Small Wheel Adaptor.
• Some assembly required. Use correct tools (10mm spanner & M4 hex wrench).
Tools are not supplied in the kit.
• Use on at and level oor or ground for your safety. Set the trainer on a large enough
mat or towel to protect the oor and carpet from your sweat and stain.
• Adjust the roller pressure to the rear tire properly in order to maximize your tire life.
Tire and roller contact will eventually wear both your tire and the trainer roller.
• If your trainer is the remote controllable version, check and adjust the remote shifter
cable tension when you cannot set at L or H even though you turn the shifter lever.
• Touching the spinning wheel and/or any other moving parts while training may cause
serious injury. Keep children and pets away from the trainer when in use.
• It is not possible to convert the non-remote resistance unit to the remote controllable
one due to a difference in the inside mechanism.
• If you feel any strange noise, smell or oil leakage, stop using VFS150 immediately and
contact the retailer where you purchased the VFS150.
• Any warranty will be void if you use VFS150 for other purpose than instructed.
Minorua offers 1-year limited warranty on the resistance unit and 5-year limited
warranty on the frame from the date of your purchase for any problem caused by
manufacturer's defect.
Any damage or problem caused by transporting process is not covered under warranty.
Any damage from shipping or moving must be made to the shipping company.
Read enclosed "Minoura Limited Warranty Policy" card for more detail.

3. Fully open both legs and place VFS150 on a at and
level oor. (see Fig. B)
At this moment, make sure all 4 foot are contacting
the oor at once to sit on the oor stable.
How To Setup Your VFS150 Trainer
2. Install the VFS unit to the Base Plate (HM-13).
(see Fig. A)
Attach the VFS unit onto the Base Plate. Adjust the
VFS unit position to be almost center of the Base
Plate, then tighten the bolts with M5 hex wrench.
- Page 4 -
1. Replace your rear wheel quick release skewer to the supplied one.
Minoura guarantees the stability only when using the supplied skewer due to the coupling inner shape.
!
If your bike's rear wheel is a hub nut type, remove the Grommet (F-9) from the
Right Side Coupling (F-1) for better stability.
You don't need the supplied quick release skewer if your wheel is a hub nut type.
It's not possible to convert your wheel from the hub nut type to the quick release
skewer type unless replacing the hub.
!
Required Tools: 1 x 10mm Spanner
1 x M4 Hex Wrench
!
Check the tightening of the pivot bolt which
connects VFS unit and Foot Pedal to the frame.
It should be tightend with correct torque that
the VFS unit will come down slowly with its own
weight when you release it. In addition, the VFS
unit should move smoothly by operating the
Foot Pedal.
If the pivot bolt has been tightend too much,
loosen a little with M4 hex wrench and 10mm
spanner.
(Fig. A)
(Fig. B)
If the both legs don’t touch
the oor at same time and if
one leg has been slightly lifted
up, pull another leg upward
strongly to adjust the pivot
part, then place the trainer on
the oor again.
TIPS

4. Place your rear wheel in between the couplings.
1) Turn the Wheel Position Adjust Knob (F-8) counter-clockwise to
retract the Left Side Coupling (F-2). (see Fig. C)
2) Turn the Hub Handle (F-7) counter-clockwise to almost fully
retract the Right Side Coupling. (see Fig. D)
(Fig. C)
(Fig. D)
(Fig. E)
3) Insert the left side (quick lever side) skewer into the Left Side
Coupling (F-2) rst.
The quick lever shaft must be inserted into the cut-out on the
coupling snugly to hold the bike stable. Turn the coupling to adjust
the cut-out position. (Fig. F)
4) While keeping this position, slowly come down the bike to align
the right side acorn nut to the Right Side Coupling (F-1).
5) Tgihten the Hub Handle clockwise to clamp the rear wheel.
Turn 2 more rotations after you feel resistance and you see the
frame starts opening slightly.
Both left and right side couplings are
designed to suit the supplied quick release
skewer. Esepcially, the left side coupling
must t perfectly in the skewer head to get
correct stability.
Any skewer type which lever is located on
the end of the axle (Fig. G) or the lever will
not be bent over right angle (Fig. H) cannot
be used on VFS150.
!
(Fig. F)
(Fig. H)
!
Too tight setting will cause damage to both VFS150 and your bike frame.
Too loose setting may cause the bike to come out of the trainer during use.

!
The tire must be away from any plastic part and touches
the Drive Roller only. (see Fig. E)
Turn the Wheel Position Adjust Knob (F-8) to locate the
tire in the center of the Drive Roller.
X
(Fig. G)
!
Do not use Wheel Position Adjust Knob for clamping the
hub axle. It must be done by the Hub Handle (F-7) only.
!
Do not over-loosen the Hub Handle, otherwise the
inside nut will have to be loosened and you cannot
clamp the hub axle with proper torque.

5. Contact the Drive Roller to the rear tire with the following steps;
- Page 6 -
(Fig. K)
(Fig. I)
(Fig. J)
The best position is that the roller comp-
resses the tire in the depth of 3 - 4 mm.
Please note too much and too less roller
pressure will bring premature tire wear.
Keep correct roller pressure and maintain
the air pressure in correct level before
using VFS150.
!
1) Pull up the Foot Pedal to release the VFS unit lock.
2) Turn the Micro Adjust Knob clockwise until the roller
comes close to the rear tire 2 - 3 mm. (see Fig. I & J)
!
Do not make the roller touch the tire. It will
bring too much compression to the tire
and will ocuur premature tire wear or burst
problem.
Foot Pedal can repeat the same compression stroke by just pushing down the pedal.
TIPS
TIPS If it's hard to tighten the knob bolt behind
the Foot Pedal, lift up the VFS unit by
hand then tighten the knob.
3) Push down the Foot Pedal to contact the roller to the tire.
(see Fig. K)
Check if the roller compresses the tire in proper depth.
4) To release the roller from the tire, just pull up the Foot
Pedal.
!
If you cannot rotate the knob but the drive
roller is still far away from the tire, the knob
has been locked by the termination of the
hex head of the inside bolt.
Loosen the knob slightly and pull the knob
for inserting the hex bolt head into the hex
hole on the knob. (see Fig. J)
While pulling the knob, tighten it until the
hex bolt head sinks into the hole.

How To Adjust Resistance Level
1. Wind the band around the handlebar and hook the metal ring to the gutter on the remote shifter base.
(see Fig. L-1)
3. The soft fabric band is pre-adjusted to t normal 22mm diameter handlebar.
If you need to mount onto an oversized or specially shaped handlebar or stem, adjust the band (see Fig. M).
At this moment, we suggest you to slide the guide pin downward (see the column) to loosen the band for
easier work.

VFS150 non-remote version doesn't have any resistance level adjustment. It is xed at all times.
On the other hand, VFS150-R remote version features a convenient remote shifter lever. You can install it on
the handlebar or stem, then you can control the resistance level without getting off the bike.

(Fig. N)
2. Flip up the lever to lock (see Fig. L-2). If it is loosened, adjust the band tighter as per instructed in the
following section.
4. To increase the resistance, twist the lever toward "H". To decrease the resistance, twist the lever towawrd
"L". (see Fig. N)
You can choose from 7 different levels to suit your desired workout level.

If you wish to use the tire sized 26 x 1.75" or smaller,
you need to install the supplied Z-shaped "Small
Wheel Adapter" between Base Plate and Mag unit to
raise up the roller height.
The direction of Z-adapter is xed so follow the
arrow printed on the top and make sure it's pointing
toward the front (toward your bike).
If the drive roller cannot reach the tire even if you
install the adaptor, make sure you have been installed
in correct direction.
Use the original cap head bolts for Base Plate, and
use the supplied hex head bolts for the Mag unit.

Why My Remote Shifter Doesn't Work Properly?
You may have a shifting problem that you cannot set at L or H position
properly due to the lengthened inner cable.
To x this problem, follow the steps to adjust the initial cable tension;
1. Set your remote shifter at "H" position and remove the shifter from
your handlebar, then straighten the cable as much as possible.
2. Pull out the plastic Cap on foot of the remote cable. (see Fig. O)
3. Hold the inside Adjusting Screw and push it toward the shifter, then
adjust the Lock Nut toward the VFS resistance unit until the nut
touches the housing to set the cable tension properly.
4. Install the Cap again.
