Comments

First I visit options to change game mode from "5 bikes, passwords allowed" into "10 bikes, no passwords". It saves time between levels by skipping password screens.
Before each level, the bike statistics can be modified according to circumstances. Too fast bike is hard to control in narrow tunnels and too powerful brakes easily turn the bike upside down. Anyway, I went with maximum stats... for everything... for every level.
The game has 25 levels + 5 bonus levels. The goal of each level is to reach the goal. The goal of each bonus level is to perform a jump over various objects. Four of the bonus levels are identical. I failed to do anything entertaining there, so I just went with fast completion. I even copy-pasted the input for the bonus levels. Sorry about that.
The final bonus level is a jump over a canyon. I ended input early, so it takes some time for the game to end, but at least it looks a bit different than all the other bonus levels. Hopefully the next player manages to pull off something more interesting there.
Health does not refill between levels, but going fast requires taking damage, so the brown repair bags need to be collected, most of which lay directly on the route. My health management went nicely, I guess. At least I was able to die about half-way through the game just while touching a checkpoint in the middle of a level to refill all health with little time lost. Also, I have very little health left when the game ends, which would be expected for a well-planned run.
Individual level times are not recorded by the game and they would make little sense in a full TAS anyway, because health management is a global issue. For any full-game run it is necessary to either waste time to collect health or use death. It is hard to tell whether collecting more repair bags would be faster than dying. I went with my intuition and used the death sequence.
The movements are very hard to optimize, because tiny changes make huge difference on how the bike behaves. Due to the chaotic nature of the bouncing bike, I recorded most of the run in 25-100% emulation speed, just trying to keep the bike speed to the max with random input variations (and mostly succeeding flawlessly!), then frame-advancing through the hard spots (mostly not succeeding flawlessly). I hope somebody polishes the run in the future. One second per level would make a 30-second difference! Also, optimizing score screens with lower digits would save time, as dunnius pointed out.

Level by level comments

The level design is not as interesting as in other games of this genre, but it allows fast-paced gameplay and I was happy to find some unexpected routes, especially in the more non-linear levels. Please ask for more explanations, if you need any!

Las Vegas:

1Casino CashpotHard track, because it requires going back and forth. Can be improved easily, but very difficult to get optimal.
2Las Vegas StripStraightforward level. Should be close to optimal.
3Easy RiderThere are lots of obstacles, but otherwise the same as above.
4Dam TroubleIt is hard to go back and forth here, but I found satisfactory ways to turn the bike around quickly.
5Heart Break HotelIt was hard to fit into the narrow space with high speed and right after that perform a big jump. It is a very lucky bounce made possible by the tiny slope, the "V" of the heart, which the rear tire touches causing enough lift to grab a ledge and fly away. This is impossible to do consistently in real-time. The rest of the level requires some precise jumps over obstacles, but nothing too hard.
6Bonus levelJump over portable toilets.

Los Angeles:

7L.A. Shake DownStraightforward.
8Sunset BoulevardStraightforward level, but there are some difficulties in avoiding slowdown while hitting the obstacles.
9Venice BeachStraightforward level, but there are mild difficulties with the ascensions.
10Hollywood HeightsStraightforward level, but there is one hard part with big stair steps.
11Beverly HillsThis level has two layers, the top-one being on the roofs of the houses allowing good speed almost throughout the level. The goal is located in an awkward place and getting there faster will probably look very cool in the next player's TAS.
12Bonus levelJump over portable toilets.

London:

13Going UndergroundThe largest shortcut in the whole run is seen here. Basically the whole level is skipped with a very hard wall jump. Setting up the jump could be done faster, but it is very difficult to fully optimize.
14The ThamesIn this level, I destroy the bike just when touching a checkpoint flag. I then respawn on that same spot with full health. Soon after that I get stuck on some stairs and maybe lose some time, but it looks funny and I couldn't find a better way to reach the goal.
15Oxford StreetBoring street.
16Heathrow Fly-byBoring fly-by.
17Tower of LondonShort level. Probably one of the closest to being perfect. Well, accelerating in this game is kinda difficult, so just studying it in more detail would result in little improvements in all levels.
18Bonus levelJump over portable toilets.

San Francisco:

19Union Square DareStraight.
20Fisherman's WharfStraight.
21Escape From AlcatrazThis is the longest level, when played normally. It rises slowly and loops from right to left multiple times. Luckily, there are some gaps on the upper parts of the level from which you would normally fall back to the lower parts of the level. With some very hard bounces, I was able to use those gaps as shortcuts.
22China TownStraight.
23Golden Gate BridgeStraight.
24Bonus levelJump over portable toilets.

Snake River Canyon:

25Rapid RiverHigh bounce for a nice shortcut. It can probably be done more smoothly, if you get a stronger upward bounce. It seems that I also needed to slow down to avoid bumping into the ceiling of the narrow tunnel, so that part looks improvable too.
26Crazy CanyonShort, but hard to optimize. Requires precise maneuvering.
27Rust in the DustOne of the hardest levels to optimize due to lots of steep rising slopes and an unconventional bounce to the goal.
28Cave MazeFast driving in narrow tunnels. Also, riding in the ceiling. Hard, but funny.
29Rocky RideLarge level with many pathways. It went OK, I guess. The ending is similar to the previous level.
30Bonus levelJump over a canyon. Ends input early. Maybe a bit sloppy for an ending. Sorry about that.
I hope you enjoy this crazy ride as much as I did!
Also, thanks to Sonikkustar for encouragement.
