IMPORTANT NOTICE
• For use with a normal 2-wheel bicycle only. Do not use a tandem, recumbent, or other.
• Hub nut type rear wheel axle is not compatible with M70-R/M80-R in standard.
You need to replace the left side coupling (UF-8) with optional "Left Side Coupling for
Hub Nut Axle".
• Fits tire size between 20x1-3/8" and 29x2.10". To use 26x1.00" or smaller tire, install
the supplied Small Wheel Adaptor.
• Some assembly required. Use correct tools (10mm spanner & M4 hex wrench).
Tools are not supplied in the kit.
• Use the supplied rear quick release skewer for maximum stability.
Minoura is not responsible for any problem caused from using your own skewer.
• Use on at and level oor or ground for your safety.
• 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.
• 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 remote controllable resistance unit to the non-remote
version one due to a difference in the inside mechanism.
• If you feel any strange noise or smell, stop using M70-R/M80-R immediately and
contact the retailer where you purchased the M70-R/M80-R.
• Any warranty will be void if you use M70-R/M80-R 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.

3. Fully open both legs and place M70-R/M80-R
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 M70-R/M80-R Trainer
2. Install the Mag unit and the Roller Pressure Adjust
Knob set (MF-3) to the frame. (see Fig. A)
Remove the pre-installed bolt from Base Plate
(LM-10).
Attach Mag unit to the bracket on frame, align the
holes, and put through the bolt.
Tighten the bolt with 10mm spanner and M4 hex
wrench.

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 is not equipped with quick release skewer and it's a hub nut type,
replace the left side coupling (UF-8) to the optional "Left Side Coupling for Hub
Nut Axle".
Minoura doesn't guarantee the stability if you don't replace the left side coupling.
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
!
Do not overtighten the bolt,
otherwise the Mag unit will
not move smoothly even if
you rotate the knob.
If properly installed,` the
Mag unit will come down
slowly with its own weight
when you release it.
Install the knob set to the welded nut on the bracket.
!
Make sure the acorn shaped spring
direction is as shown in Fig. A.
Failure will cause difculty on rotating.
(Fig. A)
(Fig. B)

4. Place your rear wheel in between the couplings.
1) Loosen the lock ring (UF-9) to allow the left
side coupling (UF-8) be free. (see Fig. C)
2) Pull up the quick hub clamp lever (UF-6) to
retract the right side coupling. (see Fig. D)
3) Insert the left side (quick lever side) skewer
into the left side coupling rst.
The quick lever shaft must be inserted into the
cut-out on the coupling to hold the bike stable.
Turn the coupling to adjust the cut-out position.
4) While keeping this position, slowly come
down the bike to align the right side acorn nut
to the right side coupling.
(Fig. C)
(Fig. D)
(Fig. E)
(Fig. F)
5) Push down the quick hub clamp lever to hold the rear wheel. (see Fig. E)
If you start feeling resistance when the lever comes at 4 o'clock position, it's correct.
If the clamping hub is too tight or too loose due to wrong position of the left side coupling, pull up the
lever to release the bike, adjust the left side coupling position and try clamping the hub again.
6) Lastly, tighten the lock ring to x the left side coupling position. (see Fig. F)
Both left and right side couplings are
designed to suit the supplied quick release
skewer. The left side coupling must t
perfectly in the skewer head to get correct
stability. (see Fig. G)
Any skewer type which lever is located on
the end of the axle (Fig. H) or the lever will
not be bent over right angle (Fig. I) cannot
be used on M70-R/M80-R.
!
(Fig. G)
(Fig. H) (Fig. I)
!
Precisely adjust the left side coupling
position to keep the correct thightness of
rear hub clamping.
Too tight setting will cause damage to both
M70-R/M80-R and your bike frame.
Too loose setting may cause the bike to
come out of the trainer during use.

6. The rear tire should sit in the almost center part of
the Drive Roller without touching any other parts.
(see Fig. L)
If the tire has touched the plastic parts (Fig. M)
due to some reasons like the rear wheel is not trued
correctly or you have installed a too fat tire, you must
adjust the Mag unit position.
To do so, loosen the backside screws with M5 hex
wrench, adjust the roller position, then tighten the
screws again tightly. (see Fig. N)
5. Contact the Drive Roller to the rear tire by turning the Roller Pressure Adjust Knob clockwise. (see Fig. J)
The best position is that the roller compresses the tire in the depth of 3 - 4 mm. (see Fig. K)
- Page 6 -
(Fig. L)
(Fig. N)(Fig. M)
(Fig. J) (Fig. K)
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 M70-R/M80-R.
!
If it's hard to tighten the knob bolt, lift up the Mag unit by hand then tighten the knob.
TIPS

!
If the rear tire has touched any other parts than the Drive Roller, the part may be
damaged and your tire will wear out quickly.
!
It is impossible to adjust the rear wheel position by adjusting the left side coupling
position. It just works to adjust the coupling distance.
5. To remove the bike from M70-R/M80-R, loosen the knob then lift up om the clamp.
If you remove the bike without changing the roller position, the next installation may become difcult
because the rear wheel has been pushed forward by the roller.

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. O-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. P).
At this moment, we suggest you to slide the guide pin downward (see the column) to loosen the band for
easier work.

V100/V130 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. Q)
2. Flip up the lever to lock (see Fig. O-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, twost the lever towawrd
"L". (see Fig. Q)
You can choose from 7 different levels to suit your desired workout level.

If you wish to use the tire sized 26 x 1.0" 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 cover cap on foot of the remote
cable. (see Fig. R and S)
3. Hold the inside adjusting screw and push it toward
the shifter, then adjust the locking nut to set the
cable tension properly. (see Fig. T)
4. Install the cover cap again.
