Building A Motorized Bicycle


Building A Motorized Bicycle

Do you want to save money on gas?

Well, 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.

Add Motor - Engine of Choice

After reading for a good amount of time and developing the style I was wanting, I chose the frame mounted "Chinese Motor". There are a number of sellers for this engine and you can find a lot of good information, both good and bad about dealers on the Motorized Bicycle Forums listed below in the "Best information about Motorized Bicycles" section.

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 came with everything pictured below and everything you need for a quick, easy installation.

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.


Below are three pictures of my project to date










My Motorized Bicycle Review

I have had a huge amount of enjoyment from building a motorized bicycle. I have now ran a tank and a half of gas through the engine.

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.

Board Track Racer Build

Early stages of build on the drawing board

The summer has slipped away into memory and I am getting ready to take my motorized bicycle apart. There are a few changes that I planed from the beginning to do and this is the time of the year to do it.

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

Unlimited Hobby Potential

The more I learn about Motorized Bicycles and the more of them I have seen, the more I realize this is an unlimited hobby.

Building Custom cars, restoring cars, building or restoring Motorcycles has become an extremely expensive hobby. Enter the Motorized Bicycle.

If you just want to build a simple vehicle using a bicycle you currently own - you're good to go.

If you like to do light customization - your good to go.

If you love to build from the ground up and do full customizations - you are good to go.

There are no limits to what you can do with a bicycle frame and motor combination.

Brilliant ideas. Loving the information on this lens.

chironseer on April 13, 2013:

Interesting, I have been on a motorized bike once, it's a good idea.

anonymous on December 07, 2012:

@anonymous: Maybe you think it's not but think about it if you get them one then they can just go on it and go for a sleep over or something so until you think about things don't say them.

anonymous on December 07, 2012:

Thank you so much I've been trying to find away but it's great now I can use my $440 bmx and my brand new whipper snipper motor.

Bob from Kansas City on December 05, 2012:

I love building and creating things, and this looks like a fun project! Thanks!

Super idea! Great for those, like my husband, who have to cycle to work and sometimes just too tired from long work hours!!! I shall pass the info to him!

Always wanted one of these!

Great for hobbyists mechanically inclined.

hamstring on August 09, 2012:

I love how you chose old-styled bikes for your projects. The classic feel just adds so much "pop"Also, the tip to not ride at "full throttle" is good. Let's face it, bikes are not made to be motorized, and it is wise to respect them as such.

ThePorkMan on August 04, 2012:

Really liked this. if we had more sidewalks around here I would love to try. Drivers are too crazy to try one of these in the street.

drsalm on July 28, 2012:

Nice lens! Congrats! I even found something suitable for my nephew.

Hey, this len is cool and it is interesting to know how to build a motor bike with something simple. It is even interesting that you can just build up a simple len and still rank #8 and #184 overall in hobbies a, games and toys. I would like to learn how can you do that. A "like" from me. Great len.

Interesting take on DIY electric bikes. I would like to build one but I'm way too lazy! I think a pedal powered bike would be better as it would force me to exercise!

I have a very rare bike called a trouble t.I am thinking of putting a gas motor on it . I am not sure What type of engine will work best for this bike.They are only three of these bikes made. It looks likeAn old Indian motorcycle. I think it would be veryCool to install a motor on it. Any thoughts?

SaltySailor on March 12, 2012:

very cool page, would be interesting to build one. I'm wondering just how loud they are? What could you compare the noise to?

goo2eyes lm on March 12, 2012:

that is really cool. how about building a solar bike? you don't need to fill it up with gas. the gas prices here are skyrocketing.that some leave the gas pumpstation without paying. angel blessed.

Edutopia on February 15, 2012:

Your finished product looks a lot like the one my friends made back from my child hood. Only yours is clean and polished and well kept and theirs was a project of love and spare parts, haha.

anonymous on January 12, 2012:

@Logemon1: go electric if you live in the usa you can get them around 300 dollars fast too up 25miles hr or kit under 200 grunbys are cheap go with the 49 cc good luck

anonymous on January 12, 2012:

my advice don't get hinesse i like the black panther muffler better make ps i put the engine on my bike ols vframe it was to much problem with parts god luck

anonymous on January 01, 2012:

Yes! Build one! Or you can buy it too. The best is the Levo motors brand. They make folding bikes too. Motorized folding bikes. The best idea.

SquidooPower on December 15, 2011:

So weird, I was just thinking about this last week. I live ona boat so was looking at a folding bike and was wondering if I could motorise it.

anonymous on December 09, 2011:

It should be the carb. Try to open and close the mixer pin, but I think, You should clean the fuel filters. Or You made wrong petrol-oil mix. There are lots of guides on the net about the maintenance. Read them. This engines are quiet strong. Does not broken easily.

anonymous on November 29, 2011:

ive had mine for 2 months tops, then i was halfway to work when it started back firing then the engine just cut out, it turns over ok then just dies like the fuels not getting through, i replaced the spark plug with an ever reliable honda but it still wont work??? any ideas??

agent009 on November 26, 2011:

I knew that people put engines on their bikes but I always associated those with motorcycles. Sounds like a great solution over a scooter!

Linda Hoxie from Idaho on November 04, 2011:

This is pretty interesting, I wouldn't have thought of putting an engine on my bike...only because I use it for exercise and recreation but my goodness the gas you could save, the places you could go, with just a little motor! Great and Green idea. Blessed!

anonymous on October 17, 2011:

Yeah. Levo motors souch a Funky stuff....

anonymous on October 11, 2011:

Hey. Mine is from the UK. Levo motors gas bike. Some of you have the same. F**kin cool man. Everyone have to try it. Old school... Also it have a cluch system too.

Great bike to use as your inspiration. I am always fascinated by the seemingly unlimited and creative ideas people have on a new build. has tons of videos and articles on building your own motorized bike. Good luck with your project.

TWWSTUDIOS on July 28, 2011:

Nice lens, great ride. Gets me excited to make more videos..

anonymous on July 19, 2011:

Hi. I have one of this amaizing bikes. It is called Levo Motors. I bought from Uk, because this is the same perfect quality motorized gas bike like the US ones, and I really want to try it. I know it is looks fun, but once you try it, you never gonna leave it. I was wondering too. It is like a life style. Now it is my life style. Lets try it. Have a nice experience...

anonymous on June 21, 2011:

Not suitable for kids but still amazing

RetroMom on May 06, 2011:

If you really want to save money. Just use an ordinary bicycle.

Now is the time for a motorized bicycle. Thanks for the inspiration!

PositiveChristi1 on September 13, 2010:

This would become complicated in the UK because a motorised vehicle would need to be registered with the Vehicle Licensing Authority.I guess it's a good idea to upgrade the rear wheel and brakes when fitting an engine to a bike?

zbikenut on August 24, 2010:

The speed you get out of a motorized bike will surprise you when you ride with someone who is riding a regular bike. Even if you are only using a 1.5 hp motor it will accelerate a lot faster than a rider can. I have built a couple of motorized bikes but they did not last very long. The advice on not running the motor at full speed all the time is very good. Rick from the Bicycle Hangar

anonymous on August 24, 2010:

I am not a fan of motorized bikes. It is the best way there is to ruin a perfectly good bicycle. Your wheels will not hold up, the brakes are not designed to handle the speed that the motor can add to your bike. I do not feel they are safe for most people. Poor brakes on a two wheeler at speed is not a good thing. [url=]Bicycle Hangar[/url]

Have you ever thought about building a motorized weed eater bike. They are challenging to build and sometimes not very pretty but fun to do. Check out my videos on youtube just type in percaine. Great job on your bike.
