How would I solar power an electric bike?
How would I solar power an electric bike's battery?
here's the bike:

here's some solar panels:

the bike's battery is like 450 watts or something like that. so if i just bought a smaller solar panel, would it be able to charge the battery after a few hours or would it only be able to charge it for the watt amount the solar panel is? i want the solar panel to be attatched to the bike so it can even be charged while using it.
also what kind of wires and stuff would i need to do that.
bill if i have a list of instructions it wouldnt be hard for me.
You have your units confused. A battery is rated in watt-hours, not watts. The one listed is "24V/10AH pack" which means it is a 24 volt battery rated at about 240 watt hours
So if you have a 20 watt solar panel and a 240 watt-hour battery, it would charge the battery in 240/20 = 12 hours. That's under ideal conditions, bright sunlight on the panel.
But there are lots of other factors to consider. Since your battery is 24 volt, you have to find a solar array that can put out 24 volts or higher. You will need a charge controller that will work with that array and with your battery set to control the charge into the battery.
Note that solar arrays put out little or zero voltage when not in direct sunlight. Also if even one part of the panel is in shade, the output will be zero.
Your comment about kinds of wires indicates you need a lot more knowledge before you tackle this.
