The upper portion of the Route is a straight, narrow, sloped path, with several Trainers on it; this is the part known as Cycling Road. Between the two gates, all travelers must ride a bicycle at all times. The path is sloped in a way that allows riders to coast southward on it with no effort. Near the southernmost end, the path divides into two smaller paths for a short distance. In Pokémon Platinum, the Cycling Road goes through slight design changes: a blue transparent archway is added to the divided part of the road, and lights are added to the sides of the road.
A colored background means that the Pokémon can be found in this location in the specified game. A white background with a colored letter means that the Pokémon cannot be found here.
Additionally, wild Pokémon can appear on the Honey tree.
While they were in the Cycling Road, the weather turned bad on them and it started to rain. Simultaneously, Brock's Pokémon Egg began to glow, indicating that it was about to hatch. For these reasons, the group decided to stop by the nearest Pokémon Center. When they got there, they encountered a Nurse Joy saddened by the fact that Trainers rarely visit the Pokémon Center she runs. She thought it was her fault that Trainers traversed the Cycling Road without stopping by and thus she was very disappointed in herself. However, with a bit of encouragement from Brock and the others, she got confident enough to help Brock with the Egg, which hatched into a Happiny.
After that, the group helped Nurse Joy and her Chansey to clean up the Pokémon Center. They then returned to the Cycling Road, continuing their journey towards Hearthome City.

In the Pokémon Adventures manga
In A Big Stink Over Stunky, Diamond, Pearl and Platinum arrived at the Cycling Road to try out the bikes they had received from Rad Rickshaw. It quickly became clear that Platinum had never cycled before, due to her repeated failures to maintain balance. Her repeated crashing disturbed a Stunky sleeping underneath the Cycling Road, and it responded by billowing a strong stench that caused Platinum to faint while on her bike. As a result, the bike started moving forward and accelerating due to the downward slope of the Cycling Road, and just as Platinum was about to fall through a gap in the road, Pearl had Platinum's Prinplup use Ice Beam to create a path above the gap that curved upwards towards the sky, allowing Platinum to come to a gentle stop as she came to and slided back to the proper road, allowing the trio to continue their journey down the Cycling Road. Meanwhile, Cyrus was seen receiving a package left for him from the reception lady in the southern Cycling Road gate.
Stunky's stench was still lingering on the group when they arrived at the southern Cycling Road gate in Passing by Probopass and Maneuvering around Magnezone, much to the disgust of everyone around them. As such, they chose to take baths on the gate's upper floor before heading to Mt. Coronet through Route 207.
Trivia
With the ability in Platinum to bike through gates, it becomes required that the player bike through the gate guarding the Cycling Road. The women at the counters will not allow the player to pass unless they are on their bike. If this is attempted in Diamond and Pearl, the player will be told "there's a time and place for everything."
If the player uses the Vs. Seeker on the bridge near the Hiker below, it is possible to get him to accept a rematch. However, it is impossible to battle with him due to the need to pass through the southern gate, which cancels the battle request.
