Again, I do not quite understand. What have the legs for this ? Maybe this is an English idiom, which I do not know ? I repeat; you are riding on the bike normally. All the time you have in the mirror the image of road behind you. You can look or not - it depends only on you. In addition, the mirror is at the height of your eyes - so natural for you height of the view. For comparison; the image in the mirror placed somewhere on the bicycle frame is from unnaturally small height.
Regards.
Legs, the two appendages attached to your **** or bum.
From what I can tell from the video you cannot ride the bike normally with your mirror. In one area of the video it shows the riders right knee bowed outward away from the frame so obviously he can see the image in the mirror; in another area of the video the rider is pedaling and you can just barely see the knee bowed out, but in the mirror you can see the riders leg is indeed bowed out as he pedals, and every 1/2 revolution of the pedal stroke the leg is partially covering the mirror image while the other 1/2 pedal stroke is not because the knee is bowed out, which would be happening all the time if the leg, knee, wasn't bowed out which then would block the mirror from being able to reflect any images from behind the bike.
And I doubt a cyclist that is touring could use the mirror at all since the panniers in the rear of the bike would be the only thing the mirror would see and nothing of the road.
AGAIN, I'm not against your mirror, for some this may be an idea mirror to have, I just don't want to have to bow out one leg to use a mirror when there are other mirrors on the market that a person doesn't have to do that. Mirrors like helmet and sunglass mounted ones (I have a sunglass one), or the bar end mirrors that a lot of people swear by, don't require any more taking the eyes off the road then does your downtube mirror, and neither of those other mirrors require bowing a body part out to use it.
Look, take the mirror to market, the worse that can happen is that it flops, but you may sell enough to make a decent living, so I say take the risk and go with it. Business is all about trial and error, if you have the stomach for this then go for it. Without trying to scare you away but in America about 78% of all new businesses fail, go bankrupt, within the first 3 years...BUT...those that failed and restart a new business have a much higher success rate with the 2nd attempt, so if this mirror does flop don't give up because your next idea may indeed be the winner. Even if the mirror only performs below average in sales but you're in the black, meaning positive cash flow, you're doing well believe it or not, and you can use the experience and money to start another idea.
I'm not against you, please note that, I just think personally that it would not work for the way I ride where my knees are place more inboard (bowed in) toward the top tube, even if my knees were parallel to the top tube the mirror still won't work for me. In America very few riders ride with their knees and legs bowed outward.
