I work at an industrial tarp company, but don't have a sewing machine at my shop. I work with heavy-duty vinyl every day. It was only a matter of time before I tried to make something bike related out of the scrap material we have laying around. The cool thing about this material, is you can fuse it with little more than a silicone roller and a heat gun. No sewing required
I normally ride a small, so my bag options are either limited, or just not that great. I decided that using my Roadie would be a better guinea pig for this project, as the triangle is much larger than on my Karate Monkey or my Fat Bike
Anyway, here's some pictures:
So its a little heavy (220z vinyl isn't exactly light) it's a little ugly, but it was mostly to test whether or not I could actually do it. The mesh pocke on there is actually the same material, so it was easy to fuse in. The reflective tape isn't great, but I had it laying around.
The seat tube and down tube have strips of ABS inside the bag and tie it into the bottle cage bosses. I have added another strap at the rear of the top tube. Overall, its not too bad for being made from garbage. I would definitely change a few thing if I were to do it again, such as make the two larger sections one piece, with a fold in the middle, if that makes any sense.
Really waterproof too!
