Will it roll in freewheel? Is freewheel released? If it will not roll, brakes are locked. Have you had either rear wheel off for flat repair?
To release brakes, look under the right rear wheel , just ahead of the axle, there will be a mechanical dics brake, two bolts hold the caliper, loosen these tow bolts, and tap the bake to get it freed up. With brake freed, oil it with WD40, and retighten the bolts!
Did you find the brakes were locked?
!! you are correct, this model has internal brake! Is the belt turning the top pulley on the transmission? And you have had neither of the rear tires off? Are you in the habit of setting the brake when you get off the unit?
