Before the injury on my leg made me stop riding, I had bought a pump to maintain the air in the rear tire which seemed to be escaping. But I was not able to use that pump much when I quit and I gave it to my nephew. I also had plans of purchasing the fancy backlight that is attached under the saddle but it did not materialize.

Some of the time there is a distinction in significance between these two structures, however in your model there isn't. In the sentence matches underneath, there is a distinction in significance.
