Up until now my ideas have been latent
    Bm      A/C#       D                 Bm  A
The cycling world will never be the same

    F# or Bm
But come first light I'll be taking out a patent
    Bm   A    D
And from that day
     Bm      A           G      D      Em
If a bike be found lying on the ground again
           A       Bm G
I'm not to blame

     D   Bm    A               Em          A
What joy it'll bring, piece of metal and a spring
        Bm                         G
Bolted down by the back wheel, activated by the heel

What joy it'll bring, piece of metal and a spring

What chicken laid the egg from whence inside an idea hatches?
     G            A                       D                 Em
From prototype to production lines to the first one hundred batches
G             F#                 Em               A
I will do for parking bikes what anchors did for sailing

There's handle bars for steering and there's tire tread for traction

A tiny bell for friends you pass and greet
     G   Gm   D   A     G                 F#
But when they add my ingenious contraption
Bm     A/C# D
Mouths will fall
     Bm           A        G        D        Em
And eyebrows will rise and staring eyes will meet
         A         Bm G

There'll be articles in newspapers and dinners at the town hall
   G                   A                   D                Em
My first check's for a thousand bucks, now that's one spicy meatball
    G                F#             Em               A
But all the fame and fortune in the world will not compare

Spring

    G                A                D                   Em
Now bikes around the world can stand alone without their owners
    G               A          D                      Em
And I can get some cash on the side but that's just a bonus
      G                F#            Em                A
When underneath their helmets I will see their smiling faces
