So I've got the Zycle Fix Cobra Beach Cruiser and I was watching these videos I've learned one thing and that is just use a 26 on the back and save you the trouble of having to chop cut saw do whatever I still got a 30 in the front,❤

The reason I had to offset the engine on my bike was because the chain would not clear the fat 4 inch tire. I also had a coaster brake set up. So in order for the sprockets to line up my engine had to be offset. Since I was putting an engine in a bike that did not have a kit designed for it, I had to fabricate parts to make it work. Evidently a jackshaft kit setup was later manufactured and sold that could allow the engine to be installed in the usual way. On a 7 speed bike this would also allow for 7 speeds on the motor bike and disc brakes front and rear. However offsetting the engine and raising the top frame tube meant that the stock intake manifold cleared the frame just fine. If I raised the frame bar a little more it would accommodate the high performance cylinder head that can be installed on the 60cc engine too. Of course skinnier tires would have also alleviated some clearance issues as well but I like the fat ones better.

Thanks for the video, this was a burning question I had for a while, I knew that rear tire was gonna be an issue clearing the chain. Guess im gonna consider another bike, I dont have any welding equipment.

Try a friction drive motor. You can mount it on a rear rack and it doesnt require a chain

Hey man I just had I have my first energy right now and I have a

I say good Job ,👍🏻✌🏻💯🤝🏻

Good idea! Those were just becoming available after I built this one.

Keep in mind that you can purchase a jackshaft kit now which would solve the tire and chain clearance. Some frames have more clearance for the engine so you can install it without welding.

Im not sure I understand your question. To make the coaster brake line up under the frame where it belongs I had to heat the coaster brake arm with a torch in a vise. Then bend it deeper so it would line up centered under the frame. Maybe 1/2 inch deeper. This requires 2 new bends. It would be a good idea to put a front brake on too.

BOSS QUIK ? WHAT IS YOUR OPINION ON THE COASTER BRAKE...PUTTING ANOTHER PIECE WHERE IT SITS ON THEN PUTTING COASTER BRAKE IF I CANT OFFSET IT..

Chuck I hoped you also got the jack shaft. I have the same issue with my 3g fat tire cruiser. I played out your entire build to compensate the lack of clearance but ended up using a smaller wheel for the time being. I was debating on whether to save for the jack shaft or go for the build. but your video instilled confidence. No botched work but I read that you are still having an issue so I want to know; IF YOU DID INSTALL A JACK SHAFT, Does it parallel to the former design. Thanks for the video.

Absolutely!

Well, I have a Dolamite bike myself, and I'm currently installing a Flying Horse motor kit. I've only had two issues thus far, 1# the intake manifold doesn't allow for enough room to attach the carburetor, and 2# the sprocket doesn't fit my fat tire wheel hub. But they have a sprocket adapter for that issue, and they make longer offset intake manifolds for the other issue. So, I'll just buy both and avoid cutting and welding my bike ( which I'm ill equipped and don't have a shop to do that. I'm glad you were able to make yours work, but I think you did unnecessary things, as there were better options.

I tried this recently and the vibration as a result of the make shift mounts was unbearable.

where are you located my friend wants to do that with his fat tire bike

I simply bought a 7 speed Dolamite with disc brakes and a shifter kit from Sick Bike Parts, no frame or sprocket mods whatsoever, took about 4-5 hours and I went riding.

Hay I got a big question for you I’m trying to put a 2 stroke engine on my fat tire ebike but the spocket is close to the right side so it would be rubbing against the tire how would I do that ???

Thanks is there anymore ways you can mount it

Oh and P.S. There's no reason to offset the engine as it does fit, you just have to get a different intake manifold. Well, you did say if anyone had a better way to let you know. And I think you had to heat up and spread the rear forks because you offset you're engine, just saying, if installed where they say to, you should be able to align it all just fine.

Boss can message me just have few questions on your build...its not easy...

There are bikes with more clearance in the middle where the motor would go!

do you sell the engine mounts ?

May you please help me out

Great build if you still have it remove the coaster brake if you haven't done so

Jackshaft kit would of made this easier.

Replace that rag joint pineapple sprocket thing before it destroys your rear wheel spokes I suggest a CNC Hub adapter mount sprocket for your motorized bicycle much better than this rubber thing your using
