    I am planing on building a 4 stroke motorized bicycle sometime mid 2015. I want to use a 2015 Schwinn coffee but I am open to recommended bikes for a build. I do kinda have my heart set on the Schwinn coffee and it looks like it could be a good engine fit without being to tall for me. I am pretty short (5 feet 7 inches) so I don't want a bike that's exceedingly, uncomfortably tall like most motorized bikes seem to be. and from what I've noticed it looks like they wouldn't need that big of a frame size. just seems like more extra unneeded space and frame height. I've ridden on a motorized bike that was to tall for me and it wasn't a very comfortable ride especially during stops and red lights. What 4 stroke bike motors are legal in California and what are reliable brands? I'm looking for something in the 50cc range. (the most common size anyway) So any experts on motorized bicycle building would be appreciated.

    I built a 2 cycle this year and have 400 happy miles on it, but have decided to build a 4 cycle bike. After looking at all of the parts, various bikes, engines and frames I went with a built bike at http://phantom-bikes.com . My bike is due here sometime in the next 7 days. I would encourage you to check them out, they have all of the parts, kits and several bikes already built. Mine is a Black Ghost 26, a version of the Phantom Classic bike featured by Jay Leno in one his garage videos. Sadly NBC took down all but a 50 second spot of the bike, but it still worth checking it out. I'll be posting pictures and maybe some videos of this project as I begin to make a few changes. Jay Lenos Phantom ride4.jpg I also have a very complete album of my first build on this site! Welcome to the bike world!!

    Thanks. I have my eye on their 4 stroke kit at http://phantom-bikes.com . The guys at the schwinn shop told me I can come in with the engine to see if it could fit.

    The Phantom bike frame is a bit bigger and longer than the frame advertised as a GT2-A, but here is a graphic of the GT2-A showing all of the dimensions you will need to check conformity with the Schwinn. Good luck! Frame 1.jpg

    Looks good. Now that frame kinda makes me want to build a bike. Is it disk break compatible? And what size wheels should I get for it? I was thinking of getting a hydraulic disk break kit I found on amazon.

    his is a 26" frame but can be used as a 24" as well. It can be ordered with pieces to handle disk brakes. The front and back can also handle drum brakes also. My bike has a drum on the front and a coaster brake on the rear. lots of choices. I have attached a picture of the Phantom frame. Have fun! Phantom frame.jpg

    I bought the complete bike already assembled. I just knew from the Phantom-bike web site that you could get all components to build the bike. I grabbed the image of the frame section, with a seat post and pieces for the neck and crank housings.

    Looks like that frame is around $265 probably another $30-$40 in shipping fees on phantombikes.com. I'm thinking of getting a frame myself so I can build an entirely custom motorized bicycle for a much cheaper price than buying a $1,000-$2,000 prebuilt phantom bike.

    I'm going with the Phantom frame. I'm thinking about painting it flat black and getting red rim cruiser wheels to give it that 50's hotrod look. How should I go about mounting a rear rack to that frame? I kinda need a rear rack.

    It is a little longer than the GT2-A and perfect for a 2 or 4 cycle engine. I was going to build my second bike from the ground up but in the end decided to start with a complete bike. I'll make enough changes and modifications to call it my own. Either way would should both end up with a great looking and good performing bike!

    I'm getting the frame soon this month. I'm ordering it from phantom bikes. I only gotta pay $100 and my uncle is paying for the rest. I checked how much a frame is and it would have a grand total price of $312.24. I can also have it painted soon to. But I'm waiting till the weather starts to get better in January before getting it painted. Can someone recommend some good wheels? I might just have to go with a set of 24's preferably with red rims and black spokes.

    After seeing my new bike today, I can say without reservation that it's one of the best frames you can find! I know you'll have a great time building your bike! You can see more of my new bike in the Album section of this site.

    So Since I'm getting the phantom ghost frame, can someone provide me a list of parts I would need to build a bike from a bare frame?

    I compiled a list of everything I wanted on my next bike and I considered the 2 cycle and 4 cycle. I spared nothing on list and I was scouring the internet for prices, which change daily, but the list still works. It is a good starting point! I have list in an Excel and PDF format but those formats can't be uploaded here. If you email me at jhammond.cpa@gmail.com I'll be happy to send either to you. You can also go to my personal area on this site at jhammondcpa and I can add you to my private email. BTW my new assembled bike arrive Monday December 1st, 2014 and is already being modified! Pictures are in my Phantom Ghost 26 album!
    Good luck and stay in touch!

    $265 for a frame without even rear brake bosses for anything?
    Pffttt...
    The GT2 is $99 delivered now at gasbike.net and what I diagramed in my pic that was used above.

    This is how the bike came out:

    That is the 4-stroke frame version, I think the 2-stroke version would better for 2 oor 4-stroke as it has an S downtube for more room.

    5'7" is smallish but it's your inseam inches that matter, just check you pant size, that is the saddle to ground size you want.

    Those pictures show the 4 cycle engine with the Jack Shaft which I have not done, but many people speak highly about those kits. I may do a Jack Shaft on my new bike, but I am sticking with the automatic for the time being and no clutch. I know prices change daily on the GT2-A frames, but the quality difference is amazing and while the Phantom frame is made for 26 inch X 2.35 inch tires it might be a Little large, but you can do 24 inch tires which would bring it back to a good fit. Of the whole process, 1/3 of the fun is planning, 1/3 of the fun is building and 1/3 is riding. Enjoy each part!

    24" wheels would lower your seat 1" but rob you of the ride bigger wheels provide, heck I like 29ers for direct drive 4-strokes, they have the low end grunt to get them rolling and once going you get a nice smooth ride and more top end, but that is beside the point as the GT2 won't take 29" wheels.

    If you want any brakes best plan ahead for 24" wheels as any frame bosses won't work.

    Now I'm toying with the idea of a 4 stroke stretch gas bike. Saw one the other day and it looked epic! Now I kinda want a stretch bike. Can a 4 stroke motor be fitted onto a stretch bike? I also want to mount some saddle bags on it to. Cargo is kind of a must for my build.
