2 stroke bike options?

    I'm looking to put together a 2 stroke bike to have some fun with occasionally. What are some good bikes in the $200 price range that provide a perfect to near perfect fit?

    I used to have a 2 stroke bike but sold it a long time ago so I've forgotten a few things about the mounting requirements for 2 strokes. How much space in the frame is needed for the seat tube clamp & the front down tube clamp for a perfect fit? I'm thinking of getting a 66/80cc flying horse kit which looks like a pretty generic 2 stroke kit.

    So, what are my options for bikes that fit 2 strokes?

    Steel mountain bikes and steel beach cruisers work best. Brand is not so important. The older, the better. Mild, tensile steel frames work better than chrome moly, to me.

    I probably would need to spend at least $300 or more on a bike if I want it made from decent steel. I think some $200 or less bikes would probably crack over time from the stress of the vibration. At least the 2 stroke engine kits still sell for under $200 usually. Leaves me more room in my budget for a decent bike.

    One of the things that bothers me about 2 strokes is they have very limited mounting options compared to 4 stroke mounts like the 4G kits have.

    Might try searching local bike shops around my neighborhood for a decent bike for around $300. I think I saw a Schwinn coffee at my local Schwinn dealer that looks like it could mount a 2 stroke. I'll have to bring the engine in to see if it can fit because buying a bike online is tricky when trying to tell if it could fit a 2 stroke.

    I had a $75 Walmart huffy cranbrook that pulled my rather large carcass around for almost 3 years. When I decided to switch over to a 4 stroke, the engine I was using at the time would not fit in the cranbrook with the stock carb, and I couldn't afford a better carb and intake manifold at the time, so I scrapped that frame and bought a reproduction (not Chinese, American made) schwinn cantilever frame from a buddy for cheap. Now I am using a 1956 road master frame that I got in a trade from another buddy, and a 79cc predator which ironically would have fit in the cranbrook. I trusted that cranbrook frame with my life. Now, wheelbender gave you some really good advice about older bikes, which you seem to have glossed over because you still seem to be thinking/asking about new bikes. I could be wrong, but that's just how it seems to me. Now if you are only interested in advice about new bikes, that's ok, not everyone wants a used older bike. But I personally happen to second wheelbenders advice. If you can find an older, especially American made, frame especially for a good price, jump on it. This roadmaster frame I got was made I'm Cleveland and it's a brazed steel frame with double top bars. The welds are in excellent condition, and this frame is going to be a lot stronger than any brand new bike I guarantee it.

    What are some good mountain bikes for $200-$300 that can fit 2 strokes? I think a mountain bike would make a good 2 stroke build. I would prefer something with a suspension fork in the front. Also U brakes would be preferred because disk brakes would get in the way of disk brakes.

    I'd say at this point your question has pretty well been answered. Not to sound like a smart***, it asking it again and again is not going to change the answers that have been given. Its obvious that you want to spend $2-300 dollars on a bike regardless of the advice that's already been given, so you go ahead and do that.

    Thinking about a Giant Simple cruiser for the 2 stroke. Think this would be a good fit?

    Doesn't have much for safety features but I can always add to it like brakes and stuff. Base price is $330 which isn't bad for a new Giant bike.

    Seatpost is a 27.2mm and it looks like I would need to use a U bolt adapter for the front down tube.

    Might also need to do some custom work to get a front suspension fork on it.

    Don't trust your life on a rear coaster brake! Try to find a bike with V-brakes on both wheels. A motorized bike goes way faster than pedaling, skidding out can be a disaster.

    The Giant has an Aluminum frame. WB6 and BB offer sage advice. Craigslist is your friend.

    This guy has early 90's American made (frame) Schwinn cruiser supreme in good shape he can't sell.

    Classic Schwinn Cruiser - $50

    Steel, Non-Chrome-Moly, Non-butted tubes, Relaxed headtube angle

    http://www.bikepedia.com has most frame specs.

    in ad, bike is NOT a cruiser, so not comfortable for long rides - also brakes are caliper which are sometimes too weak for motor speeds

    You will get far more bike for the money going to craigslist. $200 in my area would snag you a mid level MTB from the 90's. As has been said, avoid aluminium and look for steel or chromoly. Those wal-mart bikes are TOY bikes. I know a lot of guys use them with success. but if you compare a 90's Trek/specialized/Giant/Miyata/Bridgestone to the wal-mart toy and those old birds will outperform a wal-mart bike all day every day at the same price point.

    The frames and component group and wheel set will also be higher quality. Not to mention, why buy new when you could keep something else on the road?

    The Walmart bikes get branded as toys, its true. It's also apparent that the op has no interest in them. Some Walmart bikes are junk, but not all of them are. You cannot say without having ridden or at least given a very good looking over to each and every one of them, whether they could stand up to motoring or not.

    Like I said, a lot of guys have no troubles with them. I've never put a motor on one. I have owned a half dozen or more new from walmart and dozens more used. Never had one that could take the abuse of daily commuting. I'd always wreck the wheels or shifters within a month. for 8 years now I've been riding name brand bikes with mid to high level components and decent double wall aluminium wheels. I've logged thousands of miles on used quality bikes with few headaches or failures. Granted I'm a little new to throwing motors on them, but it stands to reason that I can't get to work with it by pedaling it's got no business having a motor. Now like you said, to really say much more I'd need to go look at EACH of them, and that's fair, but steel wheels, single pivot caliper brakes, and bottom of the barrel components are the hallmarks of those things. I'm also a bigger guy (240 at my peak last summer, what they call a Clydesdale in the bike world) and I ride fast and I ride hard. So your results will vary.

    I just stated this a while back, and it's been stated many times over by other members.Late 80's through midi 90's MTB's are perfect for the MAB thing.Better, down to the actual metal used in the making of the tubes.Some people associate "new" with "good", paint covers a whole lot.You're buying crap gaspipe in wally bikes.Another thing NO ONE else seems to say, when you buy a decent MTB from said era for $200 you can always sell it for that, how much would you get from a used wally bike?More reasoning why not to buy wallies, they are put together by people who get paid by how many bikes they can put together in an hour, often without proper grease.

    It's true that any Wally bike is not going to be without issue. And I agree that if it can't stand up to some serious pedaling, its got no business having a motor. I'm also a large guy, in fact I've got 35 lbs on top of your 240. I've used steel wheels and double walled alloy, honestly didn't notice a difference. Thicker spokes add strength to cheap wheels. I personally don't care which material but I will never run spokes thinner than 12g. The wheels I built for the bike I'm building are steel with 11g spokes. Now, the wheels and other components on some of these Wally bikes ain't worth a crap, but some of the frames are really strong. My crsnkbrook frame hauled me around for almost 3 years, and I inspected the welds quite often. I replaced just about everything other than the frame, but that frame was great. But for what it costs to replace all those parts, you would probably find a vintage bike maybe even for less. And if I had to choose a vintage bike or upgraded Wally bike for the same price, I'd take the vintage bike.

    My argument against steel rims is from a braking stand point. a chromed or painted steel wheel is very very slippery when its wet. A machined side wall alloy rim has much better grab to it in wet or muddy conditions. Almost as important as spoke size is spoke count. Most serious touring cyclists go with 36 or more spokes laced 3X. Sounds like you're already well on your way to having solid wheels tho! :)

    I like the Micargi Pantera 7S for ~$230.


    Front and rear V brakes, good wheels, steel frame, and the rear kit sprocket darn near aligns itself on the hub.

    Want front suspension?
    A front fork is ~$80.


    For a 2-stroke build you'll want a dual pull brake lever and small front engine mount from sickbikeparts.com.

    Yeah I'm using drums front and rear, 36 spoke, 3 cross.

    Nice "looking", but you do have to worry about that since it's a biz, anything "NEW" that's "affordable" bike-wise is chinese, I just don't like the idea. Here's some good reference:

    " With the exception of a dwindling handful of custom frame builders, not including Cannondale, the last American made bicycles were produced in 1999."

    Micargi Industries, Inc. has been manufacturing bicycles, parts and accessories since 1994. Like nearly all new bicycle company's of today, Micargi's are built in China—despite their misleading "USA" label on the head badge. Their company goal: "To offer quality bicycles at affordable prices!" Today, Micargi employs over 500 people and has a production capacity of over 500,000 bicycles per year. In 1996, Micargi went international and opened their first overseas office and distribution warehouse in South El Monte, California. Micargi Bicycles distributed blue "Rover" bicycles adorned with the "Two and a Half Men" TV show logo along with the words "100 Episodes." Micargi now produces many different models, including; beach cruisers, tandem's, children's, mountain and road bikes. "

    Like I said, 80's through mid 90's bikes are the "thang", I really like the old Raleigh's with the wrap around brazing, strong strong strong!
