"I have a driveshaft bike from another manufacturer (Newport Incline) and have experienced the same problem. The problem is that the driveshaft is only on one side, and as you peddle, the force wants to pull it off on that side. In other words, it works itself loose with time. For me, it also took about eight months. I tried to tighten it, but was not able. I took it back to the shop, where they loosened the mechanism, cleaned out the dirt that had worked its way in while it was wobbling, and then tightened it nicely. Since then, I've made sure to tighten the attachment bolts every week to keep dirt from getting in. This helps a lot. But eventually it starts to wobble again and needs to go back to the shop for cleaning and tightening. That's the only maintenance it needs. Far less than for chain-driven bikes. " more
