Bikes

After the gang's adventure in the Safari Zone, they were resting in the Pokemon Center. 
"Hey mom." Ash spoke to his mother on the phone. "I'd like you to meet someone."
Tomo appeared on the screen.
"This is Tomo." Ash introduced Tomo to his mom. 
'He's adorable.' Delia thought.
Ranger Jenny had spoken to her about Tomo a while ago, and agreed that Tomo could travel with Ash.
After Ash finished speaking with his mother, he and the gang were about to plan their next move when Nurse Joy ran over to them.
"I need your help." She said.
"There's a very sick Pokemon in Sunny Town's Pokemon Center and it needs medicine right away." She explained.
"I would take the medicine to the Pokemon myself." Nurse Joy said. "But I can't leave my Pokemon Center unattended."
The gang agreed; they needed to get to Sunny Town as soon as possible. 
"Hang on a minute." Brock said. "There might be a problem."
The only way to get to Sunny Town is over a series of bridges. The first bridge, primarily used by cars and walking was still under construction. The second bridge, was primarily used by bikes. The gang didn't possess any bikes. 
"There are plenty of spare bikes in the Pokemon Center's parking lot." Nurse Joy said. "You can use them."
After receiving the medicine from Nurse Joy, the gang started to cross the bridge on their bikes. Ash had a normal blue bike, Tomo had a green kid bike and Misty and Brock had a double seat bike. Pikachu was riding in the basket on Ash's bike and Growlithe was returned to his Poke Ball; he was too heavy for the bike. They were enjoying the bike rides; it felt nice to not walk for a change. Soon they came to a rest area. They purchased drinks at a vending machine. Ash, Pikachu and Tomo got lemonade and Misty and Brock got fresh water. 
"This is good exercise, don't you think?" Ash asked.
"Yes." Brock said. "And at the rate we're going we'll be in Sunny Town in no time."
"Hey Misty." Ash suddenly said. "Didn't you have a bike when we first met?"
"Yeah." Misty nodded. "But I left it with Nurse Joy at the Viridian City Pokemon Center."
After finishing their drinks they set off again.
Suddenly some sort of gang appeared in front of them.
"What the?!" Ash gasped.
Tomo felt scared and stood close to him.
"Who are you?!" Ash demanded.
"We are the bike gang." A biker with red hair said. "And I'm Chopper, the leader. Who are you four?"
"I'm Ash, this is my brother Tomo and these are my friends Misty and Brock." Ash introduced them.
"Now that introductions are out of the way, can you let us pass please?" 
"Not without a battle." Chopper said.
Ash was slightly annoyed. They needed to get to Sunny Town's Pokemon Center before time ran out. But he knew that the bike gang wouldn't let them pass without one, so he ultimately agreed to battle.
Chopper sent out Golem and Ash sent out Psyduck.
"Golem, flatten that duck with Rollout." Chopper said.
"Psyduck, Disable." Disable stopped Golem in it's tracks. "Now use Water Gun."
The Water Gun caused Golem a lot of pain, as it was a rock type Pokemon and weak to water type moves.
"Golem, Tackle." Chopper commanded.
"Use Ice Beam." Ash said.
Psyduck's Ice Beam trapped Golem in a block of ice. Ash had won. 
"My name's Tyra." A girl introduced herself. "Now I'm your opponent."
"Go Cloyster. Beat that wimpy duck." Ash was not happy with Tyra's comment and neither was Psyduck.
"You'll wish you hadn't said that. Let's beat her Psyduck." Psyduck quacked, then suddenly glowed. 
He changed from a yellow duck into a blue duck. Ash was happy to have a Golduck.
"Okay Golduck let's win this." 
"Cloyster, Aurora Beam." Tyra ordered.
"Protect." Ash said.
Aurora Beam was blocked by a barrier.
"Now use Focus Punch." Ash ordered.
Golduck's webbed hands glowed white and then Golduck punched Cloyster really hard. Cloyster immediately fainted.
"Well done Golduck." Ash said. Golduck smiled and saluted his trainer.
The bike gang was angered by their defeat and were just about to gang up on the group when sirens were heard. They all thought it was the police, but it was actually Team Rocket on bikes with a siren machine.
"Hey Chopper." James said.
"Hi Tyra." Jessie said.
Ash, Tomo, Misty and Brock weren't happy to see Team Rocket, but the bike gang was.
"Big Jess and Little Jim." Chopper and Tyra said.
Apparently before joining Team Rocket, Jessie and James were members of the bike gang. Jessie would swing a chain while riding her bike and James had training wheels on his bike. Team Rocket came up with a plan to get the bike gang to help them deal with Ash, Tomo, Misty and Brock.
"We need you to help deal with these pests." Jessie said.
"Yes they continue to ruin our plans." James added.
"We also need you to take their Pokemon." Meowth finished.
Ash was about to order Golduck to use Psychic on them when a real police siren could be heard. Team Rocket and the bike gang left in a hurry as they didn't want to be arrested. 
"What are you doing?" Officer Jenny asked Ash, Tomo, Misty and Brock.
"We're on our way to Sunny Town's Pokemon Center to deliver some medicine." Ash explained.
"I wish you luck." Officer Jenny said. "Be careful though."
She then left to handle another emergency.
"Now then." Ash said. "Let's stop wasting time. That bike gang made us late and that sick Pokemon is depending on us." 
"But what if we run into that bike gang again?" Misty asked.
"If we do cross paths with them again I'll change into my dragon form and scare them off." Misty, Tomo and Brock giggled, agreeing to that idea.
Just as the group started to pedal their bikes, it started raining. The gang quickly stopped and put some rain coats on then proceeded to pedal again.
The rain then evolved into a storm with strong winds.
"We need to be careful." Misty said. "Riding a bike in weather like this can be dangerous."
Just then they noticed a drawbridge that was about to be lifted into the air to let a ship pass.
"We aren't going to make it at this rate." Brock said.
"Yes we will." Ash argued. "We just have to jump from this side to the other side on our bikes."
"But Ash, that's crazy." Misty cried out. 
"What choice do we have?" Ash asked. "That Pokemon won't survive if we don't get the medicine to it."
"I agree with big brother." Tomo said. 
Even though Brock and Misty thought jumping across on their bikes was crazy and dangerous, they had to admit that Ash was right so they agreed to jump to the other side of the bridge. 
At the same time Team Rocket also cycled through the rain. They thought the twerps were crazy to cycle through the rain. But it didn't stop their desire to steal their Pokemon. When they saw the drawbridge rise up they decided to jump. When Ash, Tomo, Misty and Brock jumped across the bridge, they feared they wouldn't make it. But when they spotted Team Rocket, Ash got a idea. 
"Let's bounce." He instructed.
So he, Tomo, Misty and Brock bounced off Team Rocket's heads one by one. Thanks to his idea, they got to the other side of the drawbridge safely while Team Rocket fell into the sea. The gang was ecstatic with their success.
Just as they were going to continue cycling to Sunny Town, the bike gang surrounded them again. Ash's patience had come to a end.
"Will you stop getting in our way." He growled. "We need to get some medicine to a sick Pokemon in Sunny Town."
The bike gang was astonished by his frustration.
"Is that the reason you're cycling in this weather?" Tyra asked. 
"Yes." Misty nodded. "And if we don't hurry that Pokemon might die."
The bike gang was once again astonished by the gang's brave and kind deed. 
"That's real bikers for ya." Chopper said. "Okay gang we're going to help them."
The bikers nodded and cheered. They surrounded Ash, Tomo, Misty and Brock and cleared the runway for them. Ash was surprised, but grateful as well.
In Sunny Town, the Nurse Joy was in the Pokemon Center was worried. She received a call from her sister on the other side of the bridge about four trainers delivering the medicine to her. But it was starting to get late. The sick Pokemon, a Shellder, was breathing heavily in it's tank.
"Oh, I hope those kids get here soon." Nurse Joy said. "Otherwise this poor Shellder might not make it."
Just then Ash entered the Pokemon Center and quickly gave Nurse Joy the medicine. Nurse Joy immediately gave the medicine to Shellder and the Shellder began to feel much better.
"Thanks." Nurse Joy said to Ash, Tomo, Misty and Brock then contacted her sister and told her the good news.
Before the gang left Sunny Town, the bike gang surrounded them one final time.
"From now on you are Awesome Ash." Chopper said to Ash.
"And you are Mighty Misty." Tyra said to Misty.
Tomo was given the nickname 'Terrific Tomo' and Brock was called 'Bashing Brock'. The group laughed at that and said goodbye to the bike gang.
