You can't get to this Gold Bolt until after you shut down the reactor and open up the prison cells in the West-Wing V.I.P. Fungis on the field, and you'll win that Gold Bolt in a try or two. Stick to use rapid-fire weaponry, like the Lightning Rod or Blast Pistol, with a few Mr. This one simply requires you to defeat 50 small enemies before a poisonous gas slowly kills you. The final Gold Bolt is acquired from completing the 'Pest Control' Silver Cup challenge at Zurkie's Battleplex. Finish this one and the Gold Bolt is yours. The rest should be easy enough to get past.

Simply slow down and then accelerate again, and you should be fine. The instant you enter, stop accelerating the Speedle immediately so as to not go past the ramp you need to go off to cross the gap ahead. It's worth noting the transition moment after you go off the ramp in the Nefarious City section into a Pocket Dimension area.

It's a mostly straightforward challenge where you ride a Speedle across an obstacle course. The next Gold Bolt is acquired from completing the 'Awesome Bugtrax Done Quick' Bronze Cup challenge at Zurkie's Battleplex. Aim and center your camera until you see a reticle form on the other ramp-press circle to hop over and get that Gold Bolt. At the edge, you'll notice a magnetic ramp walk down it, and then just before the short wall with the green lights, look up, and you'll see another magnetic ramp. From your ship, walk down the ramp and hang right to take the next ramp down to a smaller docking platform. This Gold Bolt is directly underneath the center docking platform at Zurkie's.
