M-series is the light-duty magnetic tire drive trainer line mainly for daily exercise. M60-D is the special model in the new M-series with milder resistance power for the beginners, women or aged people.
New M-series has the newly designed U-shape frame. It's made of 38mm diameter steel round tubing to be clean, simple, lightweight but enough durable to support the bike stiffly.
M60-D features a convenient quick release type hub clamping system that allows you to mount/dismount the bike very quickly. Just pushing down or pulling up the lever then the right side coupling slides to engage/release the acorn nut of the rear hub. You can save the setting up time and it becomes much easier to take the bike to outside after workout.
The Eddy Current type magnetic unit of M60-D is specially tuned to fit most ordinary people like beginner, women or aged people. It's maximum power at 40 km/h is 250 watt. It's much lower than any other models but it's powerful enough for the target people.
The resistance level can be chosen from 3 levels via a manual lever on the Mag resistance unit.
