The rack mounts I can't help much with other than to say look for one's with Japanese engines like Honda for starters. You do have to watch for things like "Honda designed"- which is a crock, or weird/no name brands on the engines.
Right now I am running a rack mount, which is 28 years old with NO PROBLEMS, other than it's pretty slow- 22 mph tops speed. It's called a TAS Spitz, they were also sold under the names Free Spirit (Sears) and Bike Bug.
The engines do all come "put together", except for mounting them on the bike, but the directions for the frame mount kits are good only for the bottom of the bird cage....that where we come in...the best directions are right here on this site.
Start here- Bicycle Motor Preperation And Care | thank you very much for this info and i remember the guy that used to tune my old racing bike always surprised me with a little gift which was a new part from japan so sounds like they are still ruling with parts... will look into the 'tas spitz', and from the sounds of things i just may need to get some help from a tinkering man so when i get an engine i will send whoever decides to help me here to speak with all of you - that way none of you will have to go through explaining the abc's to me at least 2-3-4x >> if not more lol
ps - ok am out here looking for a 'tas spitz, bike bug, free spirit' and that is a vintage motor not made anymore - yes?? if it isn't being made anymore then can you guys give some other names to check out that would maybe compare to this one because based on the little i have read folks seemed to really like that motor... thanks!

thank you bikeguy and looks like they do sell rebuilt engines but they also say some of the parts being used are not coming from original manufacturer and looks like there is only a 30 day warranty being offered, all of which i am not so sure about.. so if any know of some names of newer engines to check out that are similar to the quality that some things i have read claim this engine had, please let me know... many thanks. |

that was weird and am having to type this again because post completely disappeared  saying thanks again bikeguy and this engine is unreal >> "...Gets up to 250mpg with a 200lb rider...." so maybe that means i'll get double  now all i have to do is talk a couple of friends that are acting more like parents into being ok with this idea - they have really been on me about not even considering this because of how dangerous the roads are around here... will have to test them out and see if they would be ok with my getting a motorcycle or if it's just the idea of a motorized bicycle... |

Well you do have to be careful for sure. You will find your "driving" habits have to be modified but the fun is worth it. |

lol even have to change the way you walk on a few of the roads around here for sure but you are right in that you do have to be cautious with any bike.. have gotten run off the road on a regular bike and good thing i wasn't really hurt because no one even stopped dbut then again they may not have even known that i had crashed....  |

It's a different world when riding the highways with a motorized bicycle, fo' sho'!
Always act like you are invisible. Never assume the driver of the car/SUV/dumptruck will see you or care if they do.
They cannot judge your speed or distance either.
