This thread is for people curious about my motorized bicycle I brought to Argos. I have nothing to post so I figured I should make a thread about what some of you already seen at Argos. The bicycle I made it with is a hyper beach bike from Walmart for $100, and the engine I purchased off of a bicycle engine distributor in China. I bought it for $115 at the time, but prices have gone up about 10-20 dollars from a year or two ago. I will post the few pictures I have below, and post any questions you have.
Before this bike, I had another bike I bought at fleetfarm, that is no longer available any place I know of. It was a very good quality bike, but in the engine kit, the stick chain tensioner was designed horribly. It relied on one tubular bar and friction to keep it online with the chain. The bar being tubular made it unstable, and the bottom part of the bracket was loosened from wear. I was on my way to the hardware store to get some new nuts and bolts for the tensioner, I made it no more than a quarter of a block, and the chain tensioner flew right into the rear wheel, ripping out two spokes. After that I realized, it was no more for that bike. I could not find a quality rear wheel, so I bought a new bike. Looking back on the frame itself during that incident, the whole thing warped from the pressure on one point. Anyway, I was dumb enough to think it wasn’t the tensioner’s position, but the loosened bolts. So I used the same tensioner on my new bike, and the same thing happened again. I had to buy another wheel, but I found a rear wheel for sale. Long story short I fiddled around with more tensioner locations, and I mounted one right to the frame. It is slowly bending out of shape so I need to find another location, but as of now it works. Here is the first bike I put the engine on.
