What noises correspond to what problems?

There's tons of videos on fixing, few on diagnosing

If a tire locks when you pop the clutch, what would the lack of engine noise point to?

What about if the engine sounds like it wants to engage? But dies off?

Without knowing, I'm guessing that mostly the back tire seizes with 0 noise for most of the problems.

I'm also guessing a piston seizing would only happen in motion. What problems are detected when in motion, what ones upon the next start?
 
Get going fast enough also 10mph until you get it tuned up to start easier...

If you can give more info on the problem you're having maybe we can help, high compression or a new tight engine could be the cause. You do need to pedal up to speed before releasing the clutch.

If I were to take it apart, I'm sure I could figure it out. I'm waiting for the guy who built it to get back to me.

As I was waiting, I started looking at the youtube vids, and developed a lot of general questions.

I'm guessing that this is your first motorized bicycle & you have so little understanding of how it works that you don't even know what to ask (or even if you have a real problem with the motor, (or not))?

If so?, we can help.... if not?, you need to learn to be more specific with your questions.

I highly doubt that your motor is seized! Pedal the bike hard & fast, & then pop the clutch & keep pedaling to spin the motor!!

So your HT bicycle engine won't start, well let's take a look

Chinese HT engine won’t start? Well let's see what might be the cause of your problen. Electrical 1. Improper wiring. Black magneto wire to black CDI wire, blue magneto wire to blue CDI wire. White…either remove or isolate. 2. Kill switch defective. Do not hook it up until you get the engine...
