    I like the older steel 'Felt' cruisers!!! They're very sturdy bikes & they have nice strong wheels.
    You can score a real nice used one for around $400

    yeah i would only use a steel frame. however my real concern is the inner dimensions of the frame ive seen people fit them into cranbrook frames and worksman bikes. ive been looking into this frames. theyre similar to what phantom was using before they went electric http://www.cdhpower.com/gt-c-gas-frame-w-fuel-tank-3-4l-black.html

    Hi Ruby478. Ghetto Bike uses that aluminum frame or a frame very similar to the one you mentioned with the 212cc predator engine in his Bikes For Sale. He has the respect of members of this forum who have many years of experience with motorized bicycles. However, he reinforces the entire length of the seat tube with a solid steel seat post, uses a modified moped suspension fork, mounts the engine securely with high quality machined parts and I'm confident that the chains are aligned perfectly.

    Just because people have used Cranbrook bikes doesn't mean they're good bikes!! (In fact, they're very cheap bikes)!!

    Worksman bikes are a little small in the engine area, (unless you buy one of the Sportsman Flyer 'drop loop' bikes). (The Sportsman is a great choice BTW)

    The 'Felt Faker' that you're looking at should work well, but you'll have to tilt the engine in the frame to get it to fit, & then you'll have to do some 'homework' about the oil level being in a different place inside the engine.

    The frames Venice Motor Bikes suggested above are excellent and some have 2 inch wide rims with 12g spokes and the triangle is large enough. Also the Felt "Bixby" type cruisers are also a good candidate with a very sturdy steel frame, and the engine can be mounted in a number of different orientations.

    Good luck with your build.

    I Second what VBM said. Specifically the Sportsman Flyer "drop loop'' frame. Not the bicycle frame though but one built to handle the weight and horsepower.
    http://sportsmanflyer.com/shop/motorcycles/sportsman-200/
    Read the specs on frame.
    I have a buddy with a 212pred in a Cranbrook. He has more balls than brains. As I write the frame has not failed yet, but coaster brake. (All he had) Crumbled and locked the rear wheel. You can guess the rest as they say.

    well this isnt my first build, just my first 212 build. Sportsman has always made great stuff. great guy too. in this build im using two 26x2.15 11g heavy duty steal wheels from Husky bicycles, the front wheel has a Sturmey Archer XL-FD 90mm Front Drum Brake. Ive got most my parts from gasbike cnc 44th sprocket and hub adapter along with a cnc mount. just to be on the safe side i ordered the short head as well http://www.huskybicycles.com/mm5/merchant.mvc?Store_Code=hb&Screen=PROD&Product_Code=500-260

    You have good taste in front wheels, My Flyer has the same and it brakes well.

    Chicago Schwann cruiser is best. See my threads.

    Bad idea to run that frame. To fit the 212 they also use a short machined valve cover. By doing so they do away with the stock breather and just run lines to a catch can. As a result their oil gets contaminated with blow by gases quickly. I found this out when one of his customers told me he has to change his oil every 30 miles. That’s not very good performance IMO. When I used to commute on a 212 I would change my oil the same time I did the rear tire, or about 6-800mi.

    instead of buying the felt clone i decided to buy a cranbrook and a welder and just stretch out that frame and reinforce it . i feel that will be the best option. i was thinking of streching the wheelbase to 52in but i feel ike that may be a bit long. what do you all think ?
