Minoura Japan – V100

Flywheel is a large metal disc piece on the resistance unit to work for providing smooth pedal feel as if you are riding on the road. If the trainer doesn't have flywheel, the pedal feel must become very jerky.
It is a fact that the heavier flywheel, the better pedal feel. However, too heavy flywheel sometimes cause damage on your knee due to too much load, especially when start pedaling. Too heavy flywheel often shorten your tire life. In addition, too much weight is not good for easy transportation.

AMT is Minoura's latest patent pending technology.

AMT's flywheel is specially designed to have thicker outer edge and thinner inner wall. It's the technical design approach for generating heavier weight virtually.
Our flywheel is not just a "thick metal disc" which is usually found on competitors.

Controlling resistance power is unavoidable function to enable to enjoy various patterns of training for simulating up-slope or head-wind.
However, the previous controlling system was not perfect, because each step is not equal so you sometimes get too close or too much power difference when shifting the lever.
There are many models combining with remote shifting device, but no model can provide equal power step.
For example, a Dutch trainer Tacx "Satori" features 10 positions and it offers gradual power difference in the first 3 steps, but after the 4th position, the difference will become too wide and too close then you won't be able to use the truly desired level. Honestly speaking, their 10-position control works just 4 positions.

AMT's flywheel is designed to have precisely calculated stair step shape on the inner side that controls the power difference ideally so its 7 positions are set to be exactly equal step.

We call this new design approach having above two good functions as "Advanced-Magturbo Technology", and we adopt it on every V-series trainers.

As you can see from the cut-out photo of AMT unit, the flywheel is designed to have thick outer and thin inner. This realizes to increase the moment of inertia without increasing its own weight. So AMT flywheel can work as if you are spinning much heavier flywheel.
The actual weight of V100's flywheel is 0.9 kgs but it works as 22% heavier 1.1 kgs once it spins.

You find a special stair-step shape on the inner side of the flywheel, and they are in uneven pitch.
AMT is an Eddy-Current type magnetic resistance system. Controlling resistance level is done by adjusting the distance between the magnet and the iron flywheel. The closer the distance, the more resistance.
We are precisely tuning in each step both 1) the distance and 2) the dimension of magnet facing to flywheel in order to maintain the resistance power difference exactly equal among 7 positions for enabling you to choose your favorite resistance level easily.

This technology was established together with a Japanese automobile company (we have a non-disclosure contract with them so we are not allowed to open their name here).
This flywheel design is not just for a unique shape, it's scientifically considered one.

The V100's flywheel is thinner than V150/130.

Every other AMT series has solid Neodymium magnet that generates super high magnet power. Basically it is 4 times stronger than standard Ferrite magnet.
But the main focus on V100 is providing milder performance for beginner, women and aged people while keeping its nice pedal feel. So we adopt a specially drilled magnet for V100.

There are tow solutions to control the magnet power; one is decreasing the magnetizing power and another one is reducing the cubage.
We are magnetizing the magnet by ourselves in our factory, however, unfortunately, it is available on Ferrite magnet only. Our machine is not compatible with Neodymium. So we chose reducing the cubage of magnet as the solution.
The magnet for V100 specially has a 6 mm diameter hole in the center.

If you wish to make your workout as effectively as possible, you should have a mechanism to control the resistance level without getting off the bike.
Adjusting resistance may be able to be done by shifting the gears on bike, but it will give different taste from your desired feeling, because you cannot train in your desired gear combination. And too wide gear ratio often makes pedaling jerky due to too much pedaling torque fluctuation.
V-series comes with the newly designed convenient remote shifter device to allow you perfect training experience.

The previous remote shifter's clamping device was made of metal or plastic, so it won't fit any aerodynamic carbon handlebar or stem, including the handlebar with bar-tape, but a plain round tube only.
The new shifter's clamp is constructed with flexible textile band so it can fit any dimension.
In addition, it has quick release mechanism for quite easy installation/removal.

The shifter lever size is enlarged for easier operation. The lever ratchet mechanism contains a thrust bearing for smoother and comfortable touch.

V100 adopts the newly designed U-shaped main frame as well as V130.
It is the lightest frame in our line for allowing you to transport V100 to anywhere you want.
The frame is made of 38mm diameter round steel tubing and it's durable enough to support up to 120 kgs weight (including bike weight).

V100 fits every 26" MTB, 700c road bikes, and most cross-bikes (up to 700x45c).

If you use 24x1.75" or smaller tire, install the supplied Z-shaped adaptor between Mag unit and the base plate to lift up the roller position.

The entry-level trainers such as M60-D or M70-R also adopt the U-shape frame, but V100's one has fatter and more durable 35mm diameter legs to differentiate from those models.
Although the basic frame design is same to M60 or M70, but the compatible tire size is different due to different Mag unit mounting position.

We have been adopting a plain thread type hub clamping handle for long time for clamping/releasing the bike to/from the trainer.
The large handle helped the operation so it was not so difficult, but it's true that this style has to take longer time than quick release system. And you had to keep holding the bike with another hand during this operation.

Both V-series and new M-series adopt the long-awaited quick hub clamping system on the right side (rear cog side). Just push down the lever, the coupling slides inward to catch the hub acorn nut in a second. Pull up the lever to release the coupling from the acorn nut,

Coupling distance adjustment is done by changing the left side coupling position.
The left side coupling is made of very durable single-piece solid bolt. A lock ring is built in it to fix the coupling position.

The standard setting will fit the rear hub width between 120mm and 145mm.

• Flywheel and Alloy Rotor become very HOT while workout. Do NOT touch them during and at least for 15 minutes after finishing session.
• Flywheel and the rear wheel are spinning very fast and will cause serious injury if you touch them. Keep children and pets away from trainer while using.
• The maximum load of V100 is 120 kgs including bike weight.
• The couplings fit the supplied quick release skewer only. You cannot use your own skewer on V-series trainer. You must replace the skewer before use.
• Hub nut type bike should have fitting problem. The inner diameter on coupling is larger than the hub nut so we cannot guarantee the stability. Replace the left side coupling to the optional special one.
• Any bike with internal transmission type hub cannot be used.
• V100 does NOT have the Foot-Step. It's the normal knob bolt style.
• V100 is NOT compatible with Watt-Master computer because the magnet itself is different from other V-series.

t may occur that the lever will go back to "1" position automatically even if you twist the remote shifter lever to set at "L" position. This is because the remote cable tension adjustment is not done properly (the cable length is too short).

Firstly, extend the cable as straight as possible.
As the general habit of the cable, if it's coiled, the inner cable will have to be retracted and it will cause the cable shortage. You need to set the cable as straight as possible.

Secondly, check if the cable tension adjustment screw is properly adjusted.
Pull out the black plastic cap from the foot of the cable, then you will see the adjusting screw.
Check the gap between the lock nut and the screw head. If there is any space between them, tighten the nut toward screw head to make the gap to zero.

Thirdly, turn the remote lever strongly beyond "L" position. This will push the outer cable to pull out the inner cable.

It should be up to 20 degrees. Be sure over-tightening the lever may cause serious damage to the inside mechanism.

If you cannot get any good result after trying above 3 issues, contact the shop where you purchase the trainer to replace the remote cable.

It's the sound the magnet plate hits the plastic housing. It's not a defect.
If you want to erase it, adjust the cable tension adjusting screw at little bit tighter. However, it will cause another problem that it becomes harder to set at L.

You see a bolt in the center of the remote shifter. It works keeping the lever in position. Tighter the bolt, tighter the lever.
Our magnetic resistance unit has a habit that the magnet will go back toward "H" position naturally, because the magnets are pulling each other.
At this time, if the center bolt has been loosened, the lever cannot be kept in certain position and will move toward H one or two steps.
To solve this problem, tighten the center bolt a little more by M4 hex wrench.
Be sure too much tightening will cause another problem that it will have to become hard to operate the lever.
