We have a Thule Easyfold rack and overall very pleased with it until this week. We have been transporting both my husbands and my electric bike, each weighing around 56 and 52 lbs. We like the ramp which helps older person with weak sholders and uper body strength load the bike. The problem we encountered was my bike was furtherist from the car, I secured the wheels on the rack and had tighten the knob on the tube bar. However, the tightening knob did not get locked. As we drove on the interstate the vibrations - loosened the knob and the bike fell off the rack and drug on the payment. Luckly, the wheel straps held the bike to the rack so we avoided an accident. However it is unsure if my bike is reparable. So everyone, its a great rack just be sure you LOCK ALL the pieces in place. Yes, we would probably purchase the rack again, even though I am disapointed that the srew-knob viberated loose.
