Im looking at this flashlight. Is it good to use on a bike? Would the light be spread enough to see on the road? What kind of batteries do I have to buy for it? Can I get rechargables for it? It says its suitable for cycling but that might be a gimmick tempting me to buy it. Would it being 9 inches long be a problem when using it on a bike? Im thinking about ordering this.
