The "Plug-and-Play" Bikes for 2-stroke china engines thread.

Add the Skykomish Mt. Bikes like the Marble Point from Costco. Gravy install.

Two that are Too Easy
Easy install Gary Fisher Mamba, older model. Tight fit for carb but otherwise it fits perfect. (SBP Kit and motor from Spookytooth) Me

Room to spare Fuji Odessa I think you could put a small pinto engine in it with room for (Livefastmotors 80cc) Mark

If you use the motors with the bigger front mount the Micargi Pantera is a "Plug-and-Play" Motorized Bicycle.

heres another bad one: roadmaster sx sport <-DONT USE THIS ONE

heres a good one i am using, you already have it listed: Scwhinn del mar

I think pretty much any 26" Huffy Beach Cruiser will fit the bill! I suspect they are all the same bike with different names stuck on them. Mine is a "Santa Fe"

I don't know the year on the Mamba I would have to say that it is pre 2002, since I could not find any manuals Gas Bicycle Gary Fisher Mamba Part 1 shows the bike, I still need to take and post finished pictures.

I put the motor in the frame with stock mounting kit with no issues to test for fit. The brackets are a perfect fit. Took motor off and added the shift kit.

I doubt SBP would ever sell the the rear mounting assembly without the kit but I think that it is a far superior way to mount the back side of the motor to the down tube.

It can depend on the motor. I bought 2 Raw 80 (66cc) motors. One of them had a front mount that was radiused for a 1-1/8” diameter down tube. The other was radiused for a 1-1/4” diameter down tube. Both had 1-1/8” diameter mounts for the seat tube. The included angle between the seat tube and down tube mounts measured 70 degrees on both motors.

If you want a good fit, get the motor first. Test fit different pieces of tubing to find the best diameters. Make a cardboard triangle with a 70 degree angle. Take the cutout and a set of calipers and go looking for a bike. It is unlikely that you will find a perfect fit. I bought a Schwinn Delmar because I liked it but ended up cutting out the downtube and welding in a 1-1/4” diameter tube at the correct angle for the motor. A good fit is critical so as to avoid some of the problems caused by vibrations. I saw a lot of the adapters, muffler clamps, and rubber mounts on this list. They often included filling in angle discrepancies with lead, rubber, epoxy, leather, or nothing at all. Some may work, but none are as secure as a solid mount. I decided to mount it the way that it was intended. Boring, but a sure thing.

Plug and play would be nice but may not exist. Some are easier to use. Some are more difficult. If I were designing one, it would have a 1-1/4” down tube. 1-1/8” seat tube and a 70 degree included angle, and also enough headroom. I might also consider using 1.75” tires since the 2-1/8” tires leave almost no clearance when the chains are properly aligned. They do work but alignment is just more critical. Or I might design it with a slight offset to the rear fork and/or bottom bracket. The 2-1/8” tires do ride nice. I could not find a bike that met every measurement. If you don’t mind some work. You can make it fit anything. So get the bike you like.

I had my engine on a bike that was a perfect fit, but my neglect busted the rear wheel and I just used a diffrent bike instead... was a GrantSport easy tour... still might build another and get a new wheel for it

I created this thread in a attempt to save people from buying a sad excuse for a "bike" like I picked.. and to help people find a bike that works with the "stock" mounts.

maybe all kits don't come with the longer front studs..(mine did).. but that's an "easy fix" compared to having a bike that you have to mod the intake etc on...

the diameter on the mounts could definitely be a problem though.. had no clue that they varied..

good advise.

If that is the criteria, and the stock mounts include a large tube adapter, then my vote is for the Schwinn Delmar. Low cost, steel frame, plenty of headroom, rear sprocket fits perfectly, smooth ride, cool looks. It needs some fronts brakes added and beefed up fender/rack brackets.

P.S. – Sorry, I started getting off thread in my earlier post.

was it a "Raleigh Grand Sport"?
can't find anything else on google really..

Nope.. GrantSport is the brand.. they were made for W.T Grant stores in the 1960's and 70's.. mine is a late 60's model... this is b4 the tensioner ate the spokes.. there kind of rare and hard to find, but not worth much because they were just a run of the mill bike, and offered at a cheaper price than Schwinn or Huffy..

OCC chopper> BAD!
Has any won used a 6 SPEED SENTRIX

I got a Centrix and it dosent work. Frame is too phat.

I purchased a Schwinn Sierra MOS off of CL for $25.00. The Grubee Gen II mounted up just fine. (I did have to file down the water bottle mount boss though).

Schwinn catalogs, 1980 - 1990 (498 of 522)


I originally planned to use a 1999 Trek 820. But the downtube was 45mm dia. Wouldn't work with the standard Grubee. And the SBP front mount doesn't work with the Grubee Gen II. (The Grubee is wider than the standard 1.6" that the SBP is made for). So I punted and bought the Schwinn "Iron Works" Cro-moly frame. It's down tube is 35mm.

Check out my modified intake..based on the sidedraft Weber ...pretty simple and only a couple bucks to do it .....it "Screams"

Thanks,

I bought a huffy cranbrook, and the entire install went smooth as ever, despite the horrible installation instructions! Haha.
