    Well I got the bike today a 29 inch mountain bike with nothing in the vframe.

    I can't decide between a TITAN XC50S, or the KTMC GP50R

    If possible i want to do a KRMC GP50R as a Friction Drive.

    Also how much more difficult is a in-frame vs FD?

    Maybe 8 hours of work and a lot of fabrication at times...is that a steel frame bike if not I highly reccomend a FD which usually takes an hor or 2 to install depending on tools available and your skills.

    Im a college student studying electrical engineering. My most experience with tools is tools used to open up laptops and desktops as well as assembling some dressers, desks, tv stands pretty much anything with clear written directions.

    Give us the dimensions of the inside of that frame, then we'll be able to tell you if an in-frame would work :)

    And depending on what you do, an in-frame isn't necessarily any harder to build than a friction drive (it really depends on the bike and what mods/special instances you have.)

    I'm currently building my first MB and I'm using an in-frame HS+Qmatic kit, and I don't have to do any fabricating. (I do have to bend the pedal crank arms however...) (I'm also using a clairmont which has PLENTY of room inside the frame)

    Here we have the DAX GP 50R Air
    cooled 9 hp power plant. This is an
    auto clutch engine with 420 chain
    for final drive. 10T Drive sprocket
    single speed with auto clutch twist
    and go operation. Weighs only
    18lbs or so, very compact, 49cc
    displacement. Comes with Kick
    start, Carb, CDI, and Coil Pack. Mix
    Ratio is 32:1. Only $479.99 and
    $19.00 shipping. Comes with a 90
    day warranty. Allow 5 business
    days before Engines or Engine kits
    to ship. Call or Order on line !!

    nope the gp50r is a chain drive output motor so it will not bolt right to a friction drive tunnel. To make it work i hope you are really good making custom parts out of metal

    both motors you listed are 2 strokes they need oil mixed in with the gas or will not run for long

    Just a side note as of now Dax don't have a mounting kit for that 9 HP so you are on your own mounting it...he has made that very clear so ya don't order it by mistake.

    As far as friction drives bein the same amount of work as a chain drive...man ya gotta take the back wheel off & mount the rag-joint sprocket, chain tensioner, get it aligned right or throw chains off left & right and let's not forget mount the engine that can't be made to fit every bike frame out there. I'm not meaning to be rude or anything but a friction drive fits almost every bike made without any mods or alignment problems much less mounting a sprocket perfectly centered with absolutely no wobble on a rubber rag joint (the reason I only use the inner rag joint). Friction drives are not much more than mounting a rack on the back of a bike.

    Yup, your right George. Thing I really like about FDs (friction drives) all the engine noise is behind ya.

    Not a huge deal, but is nice

    The "reliability" does not exist in the kit alone, its how it is installed etc. A "reliability rating" on motorized bicycles just dosen't exist because each bike is different.

    About the closest you could get on reliability is to part-for-part duplicate someone else's "reliable" build
