What type of engine do I need for a Trek 4500

Hello I am new and very interested in putting a engine on my trek 4500. What type of engine should I get and from where?

Welcome to the forum ides411

I am unfamiliar with that bike, check this thread for frame demensions

What kind of bike would you recommend?

Standard diamond frame, you should be able to use a china girl....the bigger the better.
If you hot $500 bones to blow then get a morini!

That Trek 4500 should fit most any engine kit. A frame mounted 2 or 4 stroke kit will fit with a fat (frame) tube front mount or muffler clamp. You should be able to use a rack mounted engine also. Most any electric should fit.
If you have disk brakes, there are vendors that make sprockets and sprocket adapters that take all of the wobble out of the back wheel.
Check out the photo gallery to see what appeals to you.
