Minoura Japan – B60

Minoura’s Magnetic “Eddy Current” benefits;

• Quiet operation
• Constant power output
• Controllable resistance

We at Minoura have been the pioneers of magnetic resistance indoor trainers. In the 80’s, there were only two ways to generate resistance; Wind fan and Roller pressure.
The Fan type was very noisy, but with a reasonably exponential power curve, up to a certain speed, at which it would stop giving resistance.
The Roller pressure type had very fast wear and very unreliable resistance.


The Minoura patented system was a major breakthrough in regards to a quiet and smooth resistance system.
The basic principles of the “Eddy Current System” are simple. There are two magnets opposing each other, and an alloy disc is located between the magnets. The magnets pull or push each other, depending on their position versus each other. The alloy rotor between the magnets cut the magnetic fields, thus creating resistance. This is a very reliable resistance method, which does not alter the resistance when heating up during exercise.
Later resistance developments such as simple magnetic and fluid based systems still find it hard to cope with heat built-up in the resistance units, causing large variations in resistance. That is why Minoura is sticking with the proven “Eddy Current” system.

The current versions of this unit have a similar design, but are more refined and tuned for optimum performance.

The first job is to replace the bicycle’s rear-wheel skewer with the one that comes with the trainer, which will ensure a perfect fit and best possible stability for the bicycle. The rear-wheel is then slipped between the axle holders and the adjustable side is tightened till very firm. Please do not use anything but hands to tighten the hub handle, there is no need for this. The resistance unit is then tightened against the tyre itself with a dial-knob.

• The Magnetic resistance unit will become HOT during the workout. Do NOT touch it during and for at least 15 minutes after finishing your workout.
• The rear wheel spins very fast and will cause serious injury if you touch it. Keep children and pets away from the trainer while in use.
• The maximum designed load of the B60 is 120 kgs including bike weight.
• The couplings are designed to fit the supplied quick release skewer. Therefore you should not use your own skewer on any Minoura trainer and use the supplied one instead.
• When using a nutted wheel on the B60, remove the black plastic cap/insert from the right side coupling.
• Most internal transmission hubs cannot be used on B60, depending on axle length and construction of the hub.
• The paint finish can fade, if left in direct sunshine, due to UV.
• B60 is NOT equipped with the Foot-Step. It's a normal knob bolt style.
• The Small Wheel Adaptor for 24” wheels is not included, but is available separately..
• The B60 is NOT compatible with Watt-Master.
