Learning to ride a bicycle changesd me a lot.

The event happened in the past, so use the past tense "changed" instead of "changes."

Hello, everyone,. I'm Demi.

Use a period instead of a comma to separate two independent sentences for clarity.

It's my honor to give this presentation today, b. Before we start, I have a quick question for you :can: Can you ride a bicycle? Great, m! Most of you can do it !

Separate into two sentences for clarity.
Add "you" in the question to make it complete.
Use a colon ":" properly, followed by a capital letter.
Include "a" before "bicycle."
Use an exclamation mark instead of a comma to show excitement, and no space before punctuation.

Today, I wannat to share with you what I learned from the experience of learning to ride a bicycle.

Use formal "want to" instead of informal "wanna" in a presentation.

My dad came home with a shiny new bicycle. The moment I saw it, a mix of eagerness and anxiety washed over me. As I first tried to mount it, my hands were sweaty with nervousness, and my legs felt wobbly. I took a few tumbles, and there were times I wanted to give up, but my dad encouraged me, saying:" y, "You should overcome the difficulties ."

Use the plural "legs" since both legs can feel wobbly.
Add a space after the comma and before the quotation mark.
Capitalize the first letter inside quotation marks.
Remove the space before the period.

"With his support, I kept going on.

"Keep going" is the correct phrase; "going on" is unnecessary here.

With his help, I practiced every day f. First, I learn ed to balance by pushing the bike with my feet on the ground, t. Then , I slowly started pedadling while my dad was beside me , still holding on .One day, he let go without me noticing, and I rode all by myself for the first time!.

Use past tense "practiced" and "learned."
Break into clearer sentences.
Correct spelling of "pedaling."
Add "was" to complete the phrase "my dad was beside me."
Fix punctuation and spacing.

I was sovery proud.

Learning to ride a bicycle, changed me a lot, i. It taught me the importance of perseverance, e. Every fall was a lesson, not a failure, i. It made me understand that in life, we must dare to try new things and never back down when faced with challenges, t. This experience has shaped me into a more tougher and more confident person.

Use past tense "changed."
Break this long run-on sentence into smaller, clearer sentences.
Use comparative adjective "tougher" instead of "more tough."

So here I am , standing on the stage.Give, giving my speech to you,and telling you about my story.

Use continuous tense "standing" and gerunds "giving," "telling" for smoothness.
Fix punctuation and spacing.

That's all t. Thank you.!

Separate into two sentences and add an exclamation mark for politeness and emphasis.

You’d add “was” after “my dad” because he WAS standing beside you.

I was so proud of myself.

This works fine, but adding “of myself” makes it look more natural.

Learning to ride a bicycle, changed me a lot, it taught me the importance of perseverance, every fall was a lesson, not a failure, it made me understand that in life, we must dare to try new things and never back down when faced with challenges, this experience has shaped me into a more tough and confident person.

So here I am , standing on the stage. Giveing my speech to you, telling you about my story.

I’m this context, we’d use the present tense as you are giving the speech right now, so we’d add “ing” to the verbs.
