Minoura Japan – M80W

M80-W's main pillar is made of oval dimension steel tubing. This is for lightweight and enough durability for easier transportation. In fact, the net weight of M80-W is only 6.1 kgs and it folds down compactly.

Usually, the basic grade model has the hub clamping mechanism only on one side, so it is impossible to mount track racing bikes or old 10-speed bikes with narrow rear hub.
M80-W has dual hub clamping mechanism on both right and left sides, so it can fit almost all types of bike.

The maximum load on M80-W is 120 kgs including bike weight.

M80-W fits 24 - 27-inch, 650 - 700c wheels. 29-inch is not compatible.

We Minoura is the pioneer of magnetic resistance system on bike trainers.
At that time, there were only two ways to generate resistance; Wind fan and Roller contact. Fan type was really loud even though its performance was very nice. Roller type had to be worn down very quickly and completely uncontrollable.
Our patented system was really welcomed to the people in '80s who wanted quiet and smooth resistance system.

The basic mechanism of Eddy Current System is very simple.
There are two magnets facing each other, and an alloy disc is located between the magnets.
The magnets pulls or pushes each other depends on the position. N-N or S-S pushes, and S-N pulls. Line of magnetic force get stronger when the magnets pull each other. At this time, the power the alloy disc cuts the lines becomes the resistance.
One side magnet is fixed on the housing and another magnet can be rotated. By this mechanism, the resistance level can be easily controlled from low to high by changing the angle of the movable magnet.

The current unit has almost same mechanism, but each parts has been tuned up to improve the quality.

We think it is necessary to have a high grade flywheel for providing quiet and smooth pedaling feel even on lower grade model. Low quality flywheel often gives uncomfortable vibration during ride and it disturbs total satisfaction of you.
We adopt the high-precision machined flywheel for M80-W instead of just steel disc type.

• Mag resistance unit may become HOT while workout. Do NOT touch it during and at least for 15 minutes after finishing session.
• The rear wheel spins very fast and will cause serious injury if touch them. Keep children and pets away from trainer while using.
• The maximum load of M80-W is 120 kgs including bike weight.
• The couplings are specially designed to fit the supplied quick release skewer. We strongly recommend you to replace the skewer to the supplied one for using the trainer. We will not guarantee anything if you use your own skewer on M80-W.
• Any bike with internal transmission type hub cannot be used.
• Hub nut type bikes can fit M80-W.
