Hello,
at first I love the idea of the Bicycle Bottle Fender Mount by Michael Mueller. It's usefull, clever and looks just awesome!!
Ok here is my attempt to re-use a plastic bottle. It's nothing special. I just thought I give it a try and it was fun making it
Use your plastic bottles for your sport exercises.
Fill up your plastic bottle with water, adjust them on each side of the Bottle Handle Bar thread and start your workout.
The weight will be up to you, by choosing the size of the bottle.
(0,2l = 200g, 0,5l = 500g, 1l = 1kg and so on..)
After hard training, take a drink out of your bottle and keep the bottle for next time

I made two models. One with and one without hollow space inside of it, because of the expensive pricing. I just don't know why both of them have the same price.
Kind Regards
