THE ONE THAT STARTED IT ALL
M3 INDOOR BIKE
Model 5501
The M3 Indoor Bike was introduced in 2006 and featured Magnetic Resistance, a Simple Self-Tensioning Poly-V Belt Drive, and a Display that showed the Power you were producing in Watts—all firsts in Indoor Cycling. It raised the bar so high, it took four years for our competition to respond. The M3 of today is also the beneficiary of over a decade of refinements, including the same power accuracy as the M3i. It features a four-way adjustable seat and a two-way adjustable handlebars. The M3 can be purchased without the Display if you so desire. Today, the M3 and its offspring are still the only Group Cycling Bikes built in the United States.
