There are electric bikes(which usually legally are considered bicycles) and there are bikes with combustion engines.(which usually are seen as either scooters/mopeds or motorcycles by the law.)
For the combustion engines you can have either 2-stroke engines(which usually are fairly small) or 4-stroke engines.
You can have one cylinder, or several. Then there are a few custom builds with turbine engines and the occasional drag/showbike with jet, or rocket engines.
Most bikes run on gasoline, but there are Diesel bikes too.
There are some online websites such as eBay that has some electric bike motors available for purchase. CraigsList also has used bike motors available in some cities.
Bike parts can be purchase at any of the MG Motors branded store locations in the UK, or general auto-parts stores who carry them. They can also be purchased online at the main MG Motors website.
They are street legal only!
