Recommended: BikeBerry 49cc BBR Tuning 5G Pull Start Bicycle Engine Kit – 4 Stroke (Click to see product)

Bike Berry is located in Brea, California and has been around since 2007. They are able to provide good quality kits at a low rate as they are a factory direct, large volume retailer. They have a highly-organised customer care team which both respond directly to customer enquiries, and produce great instructional YouTube videos.

The 49cc BBR Tuning 5G is Bike Berry’s four-stroke bicycle motor kit that you can pick up for between $300-$350, or on a monthly payment plan. The bike runs off petrol, and has a separate oil reservoir to keep the engine well lubricated. It also has a centrifugal clutch which means that there is no need to manually engage and disengage the engine.

The kit is relatively straightforward to install and can be done by someone with basic knowledge within 2-3 hours, but requires a 26-inch bike. The purchase comes with a 6-month limited warranty. Depending on weight and ratio it can reach about 25 miles per hour, and gets 100-150 miles per gallon.

Silver Slant 66cc/80cc 2 Stroke Motorized Bicycle Kits from Gas Bike (Click to see product)

The Silver Slant is an affordable product from Gas Bike, which is based in Encino, California. The business was established back in 2000 when the company’s entrepreneur, running a different e-commerce site, purchased an engine for his bike to make commuting to his merchandise warehouse easier. There was so much interest in his motorised bike that a new company was formed.

This is Gas Bike’s affordable two-stroke engine kit, which you can pick up for between $100-$150. In general, two stroke engines are twice as powerful as four stroke engines of the same size as they fire once every evolution, while a four stroke will fire only once every other evolution.

This kit is pretty easy to install, and someone with basic bike skills should be able to do it within 2-3 hours. It can be used on pretty much any men’s mike 24 inches or larger. Once installed, it needs a gasoline and oil mix to run, and has a 6-month limited warranty. Depending on weight and ratio it can reach about 40 miles per hour and 130 miles per tank.

  • Price: $
  • Engine: Two Stroke
  • Fuel: Gasoline and Oil Mix
  • Top Speed: 40 mph
  • Installation: basic, 2-3 hours

This kit is a bit more complicated to install than the 2 stroke engine, but can installed within 3-4 hours. It can be installed on pretty much any men’s bike 24 inches or larger. The engine straight gas, so no need to mix with oil, and its blissfully quiet despite its high horsepower and torque. The purchase comes with a 6-month limited warranty.

The wheel comes pretty much ready to go, and conceals a 250 watt brushless electric motor which runs off a lithium battery which can be fully charged within 5 hours.

It is relatively easy to install, requiring 2-3 hours, and comes with a 30-day warranty.

Pretty much any of these engine kits are a worthwhile investment. When choosing you need to balance speed and range, with ease of use and reliability. An electric motor will be quieter and easier to control, but offers more limited speeds and a pretty short range. A gas motor gives more power, but is messier to install and maintain, but you can get speeds of up to 40 miles per hour.

Introduction: Motorized Bicycle Fuel Mixture

In order to keep your motorized bicycle running well, you need a proper fuel mixture. This will increase the lifespan of all of the parts involved, as well as lubricate certain parts as well. The mixture consists of 2-stroke oil, and 91 octane gasoline. The oil will flow through the same parts as the gasoline, lubricating them along the way. The oil will lubricate the gas tank shutoff valve, the carburetor, and the inside of the engine (the pistons). During the combustion process, a majority of the oil, after lubricating the cylinder, will be burned off. The remainder will run through and drain out of the exhaust.

Step 1: Gather Materials

Materials Required:

You will need:

A Gas container

A funnel


2-Stroke Oil

And of course a motorized bike.

Step 2: Purchase Gasoline

This step is fairly simple- head to the gas station and purchase gasoline. 91 octane gasoline is ideal, however, 89 or 87 will work just fine. Before purchasing gasoline, determine how much you will need. The average motorized bicycle kit uses a 1/2 gallon tank, so a gallon will fill up two tanks. The bike also goes 150 mpg, so a gallon should last a fairly long time. Keep in mind that oil deteriorates while it is mixed with gasoline, so only mix the amount of oil you need.

In this demonstration, I will be mixing one gallon of fuel. I will fill up an empty gas container with one gallon of 91 octane gas.

Step 3: Purchase Oil

Oil is relatively easy to purchase, and inexpensive as well. A trip to your local automotive store will normally yield results- most stores have two stroke oil. The oil I am using is Lucas Oil 2-Stroke oil, which is blue. A majority of 2-stroke oil is blue, however, you will occasionally find other colors.

Step 4: Determine the Amount of Oil to Mix

The method for determining the amount of oil to mix is simple. A new bicycle, for the first 450 miles (3 tanks of gas) should use a mixture of 16:1- 16 parts gasoline to 1 part oil. A broken-in bicycle will use a 20:1 ratio.

I am using one gallon of fuel. This means that I will need 1/20 of a gallon of 2-stroke oil, which is about 7 oz.

Step 5: Creating the Mixture

This step, while easy, can be messy. Be sure to do this in a well ventilated area, away from any hazardous ignition sources. You are going to need to pour the necessary amount of oil into your gas container, then mix it up. This can easily be done by using a funnel. Once you have poured the oil in, close the container tightly, then swirl it around to mix the oil. DO NOT put the oil directly into the gas tank and mix it there- this could lead to inconsistency in the mixture, and inject only oil or only gasoline, which would not be good for the bicycle in any case.

Step 6: Pour in Gas Tank and Use!

Finally, fill up your gas tank to the desired amount. The resulting fuel mixture should look mostly clear, with a slight hint of the color oil you are using. Now, use the bicycle as normal, with confidence that the proper fuel-oil mixture will keep the bicycle running smoothly!

Gas bike motor

Revel in Vovka's member, continued to lick it with my tongue, but I had not yet taken it in my mouth and did not act more actively. I just caressed, feeling like a member, and together with him and its owner, tremble with excitement and vibrate from my every touch. When I felt something cool already touched my anus, I realized that it was an artificial penis, which was in no way inferior in size.

I said nothing. In the car, Inna Viktorovna sat in the front seat, lifting her skirt, exposing her thighs to the very bottom. I didnt freely gaze at them, the member began to rise, she put her hand between my legs and began to stroke the member.

I unbuttoned the button and zipper of my trousers, put my hand in my swimming trunks, lowered them, my penis jumped out to freedom. She bared her head, I stopped the car.
