Learn About Building A Motorized Bicycle
Tired of paying high gas prices?
The answer may be the Motorized Bicycle.
As far back as 1892 people put motors on bicycles.
With today's 2 stroke and 4 stroke engines you can Expect to get 150 miles per gallon after the initial break in period.
The normal bicycle fuel tank holds 1/2 gallon of gas allowing approx 75 miles per tank full.
Are these engines dependable?
You can expect to get thousands of miles of life out of your engine if you follow a few guidelines:
1. Follow the break in period guidelines - Break in period lasts for the first 4 tanks or 2 gallons of gas.
2. Keep up with routine maintenance on your motorized bike.
3. Don't ride at full throttle often.
4. Use a good quality motorcycle synthetic 2 stroke oil - Mix at a 20:1 ratio or 7oz of oil per 1 gallon of gas.
Decisions you might face.
There are many decisions you will have to make about motorized bicycling.
Do you have a bicycle? If you do, the type of drive that will best suit your current bicycle. Frame mount or rack mount.
Perhaps you do not have a bicycle. You need to decide if you want to buy a completed bicycle/engine combination or purchase a specific style of bicycle and add your own engine to it.
What follows is to help you better understand your options. The advantages and disadvantages of each system and how to get the most enjoyment out of building a motorized bicycle.
Building My Dream Motorized Bicycle
Building my Motorized Bicycle in words and pictures.
I purchased a Micargi Tahiti Bicycle for my dream ride.
You can choose a style that fits your dream.
Here is the Bicycle I chose to begin with.

Micargi Tahiti Stock Beginnings
Add Motor - Engine of Choice
I got my engine from Bob at Blue Collar Bikes. I have been extremely happy with delivery and follow up from Bob and will do business with him again.
The engine kit comes with everything pictured below and everything you need for a quick, easy installation.

Engine of Choice
My Dream as a Finished Product
From the humble beginning using a Micargi Tahiti bicycle and adding the motor from Blue Collar Bikes, I have now created my own "Motorized Bicycle."
I changed a couple of the stock items that came with the micargi... Seat and handle bars
I also added a cantilever front brake to the Bicycle. This model bike does not come with a front brake, if you need to stop quickly a front break is gold.
On the engine I added some paint and replaced the mounting studs with allthread 1/4x20 for a little added strength.
Beyond this I decided not to make any changes or additions to the engine as it comes from the factory. I mainly made this decision to test the dependablity as well as get in a little riding time before the rainy season hits.
This winter I will be taking the bike back down and making changes and some customization to the bikes appearance. For now, I am thrilled with the results.

My Motorized Bicycle Review
I have yet to go any place on this bike without people asking me questions and commenting on it. No only the uniqueness of the engine added but the over all look of the bicycle as well.
A half dozen of my friends have also ridden this motorized bicycle and I get the feeling that come spring I will have a good amount of companions zipping around the area with me.

1914 Pope Board Track Racer
Board Track Racer Build
Early stages of build on the drawing board
Mean while I have a new project on my drawing board. I want to build a Board Track Racer Style motored bicycle.
Above is a picture of a 1914 pope board track racer and that is the look I am going for. Below there is a picture of a Workman Bicycle that I will be using for the basis of my build.
If you notice the frames are very similar in style
I will need to construct a fuel tank that will fit between the top and bottom cross bars.
I will also need to decide if I want to build another China Girl 2 stroke or go with a 4 stroke Japanese engine this time. There is still plenty of time to decide.
I know that I will not use the sandwich sprocket on this one so the rear hub sprocket is another area that I will be looking into.
That is about where I am at this point and this winter while the rain and snow fall and the wind blows. I can be found sitting by the fire dreaming of my Board Track Racer build

Although whe had some difficulty with: installing the rear sprocket, cutting the chain to the correct length, the chain tensioner, figuring out how to wire the kill button, and modifying the engine mount, the total installation time was about 7 hours. To do it a second time would only take half of that. Finished we had a lot of fun with the bike.

I built one of these bikes with my son. It took us about 7 hours to install the engine, the only difficult part was figuring out the right way to install the large sprocket on the back wheel. When finished we had a lot of fun with it and it performed really well.

in reply to mreading I have a single speed. The dust cover is a small cover over the wheel bearings, its located just under the break arm. It comes as part of the wheel assembly.

I'm not sure what I would choose between the two, but interesting lens.

Jemma says:
2 Stroke every time. For power from a small engine, tunability and reliability you cant beat a two stroke. Mine is a belt drive and makes 34mph top speed from a 32cc piped engine.
Posted September 17, 2008
Jemma says:
For the application - ie power from limited space and cc's and simplicity of maintainence (with a good quality engine) 2-strokes win hands down. You wont find a 30cc 4-stroke engine putting out up to 4hp! And you can put a tuned pipe on for even more power.
My MB is 32cc piped 2 stroke and will make a top speed of 34mph

DMedley says:
It really depends on your needs and your skills. I began with a 2 stroke engine for simplicity, learning and it fit the style of ride I wanted to create. So for the mechanically inclined beginner, I believe the 2 stroke is the best.

4 stroke
AndrewTwidwell says:
4 stroke engines are so much more efficient and a whole lot better for air quality.
