No fossil fuels used

Everything here is making assumptions, your assuming the person will get cramped, I'm assuming this is energy preferable in X very specific scenario, theres no numbers or study to back anything up. The point is just that even if it is less energetically efficient most of the time, even most of the time, its not useless, and people ride shit for different reasons than just that, which is probably why you didnt quote that part of my post

It is green way to travel and no pedaling needed. You are frustrated becouse this girl is more innovative than you combined,

Thats some epic falseflagging, mind if I steal it?

This is Veeky Forums, so you're going too have to expect somebody would do the math. A liter of air is about 1.286 grams. Let's say that it takes five pumps from the pump to gather one liter of air. If you pumped once per second, then you'd be gathering A fifth of a liter per pump, thus 0.2552 grams per second. By that rate it would take TEN FUCKING HOURS to gather 10000 grams of air. TEN FUCKING HOURS OF PUMPING JUST TO DRIVE YOUR LAZY ASS A TRIP THAT WOULD TAKE TWO HOURS OF NORMAL PETALING.

You're defending being retarded by wasting time and effort than pedaling

First it was preference now it's cardio problems, now it's hot and cold and now you think I don't know it's not a vacuum

It doesnt matter how you skew it, pumping air into an air tank to run your bike is always less efficient than just pedaling the bike

>always
no. read

All that stupd shit you just wrote but nowhere in it do you justify how much air you need to get where you need to go. Extra points for converting to grams for some nonsensical reason.

Fuck off retard go run your retard bike with retard air because you'd rather blow 10 hours pumping your air tank to do something you can already do, pedal

Its in the picture you fucking retard

10kg to go 60km
