I agreed, and wrote about How to Bunny Hop.
But it soon became clear that different people have slightly different definitions of a bunny hop. For example, Blam talks about different bunny hops, this answer links to a Danny MacAskill video showing bunny hops, and this BillyNair answer describes similar bunny hops. Most of them are different to what I described - at speed, clipped in, both wheels of the ground.
Where did I get my definition from? Err, that would be 40 (or is it 50?) years ago, before BMX was heard of, when a bunch of us kids would do whatever came to mind on our road bikes. We did the normal stupid stuff kids do: jumps, jousting, riding down stairs, along the top of fences, picking up stuff, yadda yadda, etc, etc. We called getting both wheels off the ground at speed without the help of a ramp, a bunny hop. Everyone else seemed to call it the same thing.
I look forward to hearing about the different jumps you do, on what bike, and what they're called.
I'd like to add a definition to our Terminology index.
