There may be some mix-up because the ride system for a lightcycle ride would probably be based on is literally called a
motorbike coaster. It's not too far of a leap to go from "bike coaster" to "speeder bikes"... because, you know... they're bikes and they go fast.
Im aware of a motorbike coaster. Im just saying if you have a source who has knowledge of the project they would definitely know the difference between the two and you would be sure to pass that along, otherwise you're just mixing up the content your source gave you, and who knows what else was made up and added in the process.
Anyway is a coaster even plausible there? They had structural damage from the rocket rods and the forces behind a coaster would be much more. Not to mention the incredibly tight spaces the track runs through, it would require a major rework just to get the buildings to have enough room to fit the coaster. Coasters have a fairly big ride envelope. Oh the tracks on coasters have a tendency to flex as the train goes over them, which would require even more room through the buildings of TL, and they are really loud, anyone inside of the building would hear a lovely roar every time one went through. And Coasters aren't exactly known for being able to move a large amount of people through them so the wait times for one would be incredible there, especially given that they wouldn't be able to: A. Use long trains (longer trains means you need more gradual turns so you'd need more space) and B. Have a large amount of trains (This would be a launch coaster most likely and typically you add more block sections to keep the cars from colliding, and to give them a place to stop in the event of an emergency, but usually block sections are raised in the air so if a ride has to stop momentarily it will be able to build enough speed to clear the rest of the track. Seeing as they probably don't have enough space for all those drops they would have to use more launch sections. Launch coasters have a terrible reputation when it comes to reliability, and adding multiple launches would make it worse)
Now when it comes to the Monsters Inc Coaster, Im not sure why they would replace a franchise that Disney is investing in and trying to build (The muppets)with one that probably doesn't have much staying power, and yes Im aware that there is a prequel coming out for monsters inc.
But my biggest question when it comes to both of these projects is how would disney benefit from building essentially a Monsters Inc mini land, and a Tron attraction (for the record I think a light cycle coaster would be awesome, especially if done right i.e a completely dark dueling coaster with illuminated trains and track). If DL is worried about staying power and being able to draw people in why would they use Tron, a franchise that doesn't appeal to a lot of people and most likely never will, and Monsters Inc, which is one of the lesser pixar properties and doesn't have much of a future, at least with cars there is the insane merchandise market to keep it going. Why wouldn't they build a Marvel themed land instead of monsters inc? Marvel has a much bigger draw and always will. And instead of Tron why wouldn't they build either a marvel based attraction or a star wars attraction? Each of which have a much much bigger appeal than Tron.
Will you ever hear anyone say "Yea Universal Studios just added Harry Potter, but Disneyland just added a new Monsters Inc ride, and a Tron ride!! We're gonna go there instead!" Lets face it, thats probably not gonna happen. However you are much more likely to hear "Instead of going to see the new H.P attractions lets go to Disneyland and see the new Marvel land, or the new star wars attraction"
