Re: What's the real reason for Chain Tensioners
I've actually got a story. It's not funny (at least for me) and was probably the worst experience I've had with these bikes so far.
So....Once day I was riding my Huffy Crankbook to the bike shop. The whole assembly process was complete (sprocket, engine...everything) except for the chain. I did not have the right size chain tool at the time and didn't know what else to do. So I rode this heavy gear-less bike 7 miles to my bike shop. After about 45 minutes or so I get there. I mark the chain to where I need it, take it into the shop and get it cut down to size. I then proceed to install the chain for the first time on my bike. It's perfect and I do a last minute check of everything before my first start in the shops parking lot. What I failed to realize is that the damn idler wheel was not on there tight enough and I didn't think of wrapping inner tubbing before mounting it. So I get the bike up to speed, pop the clutch, and vrooooommmm!!!! First thing that went wrong was the throttle. I hadn't lubed up the needle so it was stuck and with the engine racing I went flying from one end of the parking lot to the other in the blink of an eye. This being my first time riding a motorized bicycle so I didn't think to pull the clutch and I had no lever pull brakes! So I make a sharp turn and just barely dodge the curb only to be shot into the middle of the street. So there I am panicking thinking I'm going to get hit by a car on a bike I can't control. But all of a sudden I hear a noise. SNAP!!! The rear wheel locks up completely, stalls the engine and brings me to a complete stop in the middle of the street. I quickly lift of the back wheel and run back onto the side walk. Once there I look down and the idler wheel bent into the spooks Snapping 5 right off and had 3 partially broken off hanging off the side of the wheel. Shocked, angry and very tired I drop the bike and start the "cuss fest." After 15 minutes of calming down I call my friend who brings his truck and drives me back home. After that I stripped the engine off the bike and took the bike back to Walmart. After another 2 months I went out and bought my self a Schwinn Riverside. All is good now. Got 350 miles and counting on my new bike. I know the idler wheel ruined this perfectly good bike but I was actually glad I had it then. I don't know what would have happened if it didn't bend into the spokes.
