Minoura Japan – M20-V

The M20-V is an M-series model, specially designed for the very popular Mini-Velo bikes. The frame has been altered to suit all possible wheel sizes in the 18 and 20” sizing, as well as 17x1.1/4”. It has also been constructed so that the bike will remain quite horizontal and a standard front wheel riser will level the bike even more.

The M20's frame design was built for strength and stability. It uses large 38mm steel tubing for the U-shape, which is durable enough to supply 100% support, for riders up to 120 kg in weight. The U-shape is supported by 29mm legs, which fold slightly outwards for a very stable platform. The legs also fold flat for best possible storage.

The AMT units are recognised by the exposed type flywheels, for improved cooling. The stepped design puts more weight at the outside of the flywheel, giving a much higher virtual weight than the actual as you are speeding up. This means that when you start from nil, it acts like a small flywheel, easy on the muscles and machinery. As you speed up, it increases by more than a third, which is very noticeable. Moving a trainer with less flywheel weight is also nice.

As far as power goes they get more power than M-series, via the much stronger Neodymium magnets. Because of the unique Minoura design, it has again very constant power and no fading as the unit warms up. With the AMT design the flywheel is actually part of the resitance system, by supplying interference to the magnetic flow, which causes resistance. Please be aware the flywheel gets hot and spins at a high speed, so do not touch during or after a workout.

The AMT units resistance levels have exact calculated steps between them, unlike most other systems. Most others have up to 50% of the levels that are so close together, that the rider cannot notice any difference. Minoura levels have a noticeable output difference for each and every level.

The V20-V can also be used with the Watt-Master computer, which monitors output power, speed, cadence, time and distance, for a more motivational training workout. The Watt-Master also allows you to pre-determine the workout. It can also be used on the road, as a basic computer.

All M-series models feature a convenient quick release type hub clamping system, allowing you to engage/release the bike very quickly. By moving the special lever up/down, the right side coupling slides in/out, fixing/releasing the wheel from the frame. This is a great time saver in setting up time, before/after your workout. After you secure the bicycle, you tighten the resistance unit against the tyre itself with a dial-knob.

The magnets used in the AMT units are Neodymium material. These are 4x stronger then standard Ferrite models.
and change characteristics even more. Therefore AMT offers a reliable resistance and troublesome usage for many years, which is not possible to achieve with Fluid.

• Mag resistance unit should 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 it. Keep children and pets away from trainer while using.
• The maximum load of M20-V is 120 kgs including bike weight.
• The couplings fit the supplied quick release skewer only. You cannot use your own skewer on Minoura 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 standard hub nut so we cannot guarantee the stability. Replace the left side coupling to the optional special one.
• Any internal transmission type hub cannot be used on M20-V.
• M20-V does NOT equipped with the Foot-Step. It's a normal knob bolt style.
