*Note – engine will be a silver YD-100 engine. These are the LARGEST 2-stroke bike engines available! The black one shown in pics is for reference only. Engine will be silver.


This 26″ deluxe beach cruiser and YD-100 Engine Combo sports a killer paint job, FAT classic tires, heavy-duty 12 gauge spokes & removable front basket & cup holder. Perfect for leisurely cruising around at the beach – or wherever you happen to be.

This is no junk bike, this is a solid, Steel-Frame beach cruiser designed in California. The engine is a New SILVER YD-100 model, and it’s powerful enough to power the bike 30+ MPH, and it gets about 90 MPG. You can fill the 1/2 gallon tank for UNDER 2 BUCKS! That will carry you 65 miles!!!!! Try that in a car.

You get the complete bike & complete engine kit in 2 separate boxes, and everything you need to put this motorized bike together is included. Everything except the tools that is.

I can provide a ton of information & resources about motorized bikes & you can always email me if you should have any questions while assembling/riding.


Please note: You do need some level of mechanical ability to assemble & maintain the motorized bike you build. Although a lot of people can assemble this in an afternoon without asking for any help, I do not claim that it is an easy project for everyone.  It is actually quite difficult for some people, to tell you the truth.  If you run into something that you’re not sure of please contact me for assistance.  I’m always happy to help. YOU WILL HAVE TO MAKE REPAIRS AND ADJUSTMENTS OFTEN to your motorized bike/engine. Failure to follow instructions can lead to damaged parts. I offer no warranty on any parts so please ask me for assistance if you’re not sure about something.


You will also need tools. Tools needed include:


-Drill (for one small hole)

-Allen wrenches (metric)

-Socket set (metric)

-Chain Breaker (or you can cut it to length)

-Adjustable wrench

-Shop scissors or utility knife

-Grease (optional, but a good idea)


Please note: Although the engines & bikes that come with these kits are all the same, there are sometimes some variations in the accessories. These variations are not of lesser or great value or quality, they are simply cosmetic.

These differences can include:

-different style grips than pictured.

-chrome or black muffler.

-decals on bike can easily be removed.

-trimming rear fender with tin snips is recommended.

Please also note, if you have any difficulty during your build please ask for help. I am here to help, and I won’t leave you hanging.

Also – if you receive anything that is damaged right out of the box, please contact me within 48 hours of receipt of delivery. Everything is shipped brand-new & in 100% condition from my suppliers, and on the rare occasion something will get damaged during shipping.

Thank you!
