DISQUS

Please, leave the engineering to engineers. - We did, and look how the planet turned out. I think it’s time we started listening to other ideas as well.

WOW! Never expected that response.
I've got no problem with biking. I'm a cyclist myself. I'm also a mechanical engineer. Sorry - a plastic bike is a waste of plastic. It will never outlast a steel or aluminum bike. It looks nice, I guess, but it is not more efficient. Is it lighter than an aluminum frame? Cheaper? Stronger? No. So what is the point? Will a "cool" looking bike get more people to ride? Doubtful.

You've executed an interesting industrial design, but every single bicycle already in existence, except for some with molded thermoset plastic frame tubes, is ALREADY RECYCLABLE!

Good luck with it, though.

Steel and aluminum used for current bicycles are already infinitely recyclable. In fact, a large percentage of the steel and aluminum used for bike frames and components has already been through the recycling process. Additionally, the lifespan of a steel or aluminum bicycle frame will be orders of magnitude longer than ANY plastic bike, especially recycled polypropylene. Please, leave the engineering to engineers.
