Don't make me waste minutes of my time watching vague videos before i can actually find out what it is. Give me a technical drawing first, or at the very least have the decency and courtesy to have your video display what it does, accurately, in the first ten seconds instead of making me watch someone pump their bike.<p>Also, holy shit, blinking backlights are a massive danger source. They may be nice when you're riding on a narrow country road with nothing at all for miles but you, your bike, and a psycho car driver; however when you're in a city, on a bike path, and there's a person behind you, your blinking light will rob them of the ability to effectively concentrate on the surroundings because your blinking light will keep drawing their attention. And don't try to tell me you'll switch it off/set it to no-blink when you switch from riding on the road to riding on a bike path. You'll be too lazy to. I'd be too lazy to.<p>In effect this project is badly marketing a thing that will increase traffic danger.<p>I'd actually like this if it wasn't for the latter point.
