Just purchased a 2nd Traxion for my wife; after she borrowed mine she had to have one. This one arrived in perfect condition via UPS. Had to fine tune the brakes and shifters but that is easy. The people here having pedal/crank problems are causing the problem themselves by installing them dry and severly over tightening them. Put a little grease on the threads and take them down to just beyond finger tight. They are threaded opposite of the crank rotation and will not back out, and if you ever need to replace them they'll come out easily without seizing or galling. Great bike for the money!
The big limitation that I can see, is that if there is any deflection when the rider gets on the bike, that means that the rider is essentially pedaling uphill all the time (Because he has to compress the springs as he moves forward). The other problem is that unless the springs are precisely calibrated to the riders weight this will really destroy the rolling efficiency of the bicycle. Malcolm Jacks May 23, 2020 03:09 AM

Good Shocks and struts keep applied downward pressure to keep the tire in firm constant contact with the road at all times. They can: contribute to a smoother driving experience, help decrease drive and squat during hard braking situations, and reduce the force of forward gravity when braking under a panicked situation (helps avoid accidents!).
