Chainsaw bike! Sounds spooky, right? But have imagined how much functionality you will be able to obtain with this bike. But to acquire that, you have first to learn this. Do you know how you can do that? Well, don’t worry; I have crafted this article so that even a layperson will be able to make his own chainsaw bike. So, let’s see how to do that.

How To Put A Chainsaw Motor On A Bicycle

First of all, you have to remove the chainsaw’s cover and adjust the 10 MM V belt pulley with the chainsaw. Then, take an engine mounting bracket; you can use the simplest one made out of scrap metals for this process. Next, mount the chainsaw with this bracket through its existing holes. Of course, this means you are gonna have to make the holes according to that position.

 After that, take a 26:1 worm gear reducer and adjust a 16-tooth sprocket with it. You may need to replace the center nut with a large one for that. Next, take a 10×350 V-belt and equip it with worm gear and the chainsaw machine. Finally, secure it on the mounting bracket properly.

Next, take a one-way bike sprocket and a 24-tooth sprocket. Weld them on one another. Remove the old wheel from your bicycle and equip this sprocket with it. Now, set the wheel again and adjust the chainsaw machine on your cycle’s rear part of the carrier. Adjust the chains along with the sprockets, and that’s it; your chainsaw bike is ready to go now. You can now ride in your own will and go as far as you want to go.

Precautions:

– Wear safety goggles to protect your eyes from dirt and debris.

– Make sure the chainsaw engine is off before you start working on it to avoid injury.

– Use a piece of wood as a buffer between the handlebars of your bicycle and the spinning saw blade while attaching them with screws. This will prevent friction burns or injuries if they touch during operation.

– For those who want their bike without brakes, use an old brake cable instead of the metal wire that connects both handles when pedaling backward for braking purposes.

The Benefit of Chainsaw Motor on A Bicycle:

The benefit of putting a chainsaw motor on a bicycle is that the bike can go up and down hills without you having to pedal. The only thing you will have to do is turn your body in the direction that needs power, but it allows for easier pedaling when going downhill because there’s gravity aiding it.

It also means that if your feet get tired or hurt before you finish riding, which often happens with long or steep rides, then they don’t matter anymore! You’ll still be able to use them just as much as anyone else who doesn’t need their legs for balance.

Disadvantages of Chainsaw Motor on A Bicycle:

The disadvantages of putting chainsaw motors on bicycles are that it is hard and time-consuming. You have to be very careful when drilling the hole for the motor since you can damage your bike and injure yourself if done wrong. It will take many hours either with electric tools or by hand, so make sure to put in enough effort before beginning this project. Otherwise, it won’t work out too well. There are other ways you could go about using a bicycle as transportation instead of pedal-powered bikes, which don’t require any fuel at all.

For easier access, remove the cover of your chainsaw. This will help you determine the correct positioning of the V-belt pulley. But make sure the chainsaw engine is off before you do this. The motor’s cover will be put back on after you have attached the chainsaw to the bicycle. It is essential to have the chainsaw in good working condition before starting this project. You don’t want to have any unexpected breakdowns while riding.

Step 3: Attach the V-Belt Pulley

Take your 10 MM V-belt pulley and attach it to the chainsaw. Make sure it is tightly secured; a loose pulley will not work either. You can also use a metal screw or bolt to secure the pulley in place. It is important to align the pulley with the chainsaw’s drive shaft. You can use a ruler or measuring tape to ensure proper alignment. But make sure the pulley does not obstruct any of the chainsaw’s moving parts. The V-belt pulley is what will connect the chainsaw to the bicycle’s sprocket. You can also use a pulley of a different size, depending on your preference.

Step 4: Create a Mounting Bracket

Next, create a mounting bracket for your chainsaw motor. You can use scrap metal and bend it into a shape that will fit snugly onto your bicycle. This will help to keep the motor in place while the bicycle is in motion. I recommend using a 2-inch angle bracket for this purpose. You may also need to drill holes in the bracket according to the placement of your chainsaw’s attachment points. It is essential to make sure the bracket is sturdy and can hold the weight of the motor. The bracket will be attached to the bicycle’s frame.

Step 5: Create Holes for the Mounting Bracket

You may need to drill holes into your bicycle’s frame to attach the mounting bracket. Make sure you mark and measure the position of the holes before drilling them. This will help ensure that everything lines up correctly. There should be two holes on the rear part of your bicycle’s frame and two smaller holes on the bottom bracket. You can also use a 5/16-inch bolt and nut to attach the mounting bracket. But make sure it is securely fastened to avoid any accidents while riding. It is essential to have a stable and sturdy base for the chainsaw motor.

Step 6: Attach the Mounting Bracket to the Bicycle

Once you have drilled the holes, attach the bracket to your bicycle’s frame using screws or bolts. Make sure the bracket is tightly secured and will not move while riding. Otherwise, it could cause damage to your bicycle or result in injury. It is also essential to ensure that the bracket is placed in a way that will not interfere with your pedaling motion. However, keep in mind that it should be close enough to the chain sprockets for easy connection to the chainsaw motor.

Step 7: Attach the Chainsaw Motor

Now it’s time to attach the chain saw motor to the bicycle. Place the chainsaw on its side so that it is parallel to the bicycle’s frame. Then use bolts or screws to connect the chainsaw’s mounting holes to the bracket attached to your bike. It is important to securely fasten the chainsaw onto the bicycle as this will be providing the main source of power. The motor should be placed on the same side as the rear wheel of your bicycle.

Step 8: Connect the Motor to the Sprocket

After you have attached the chainsaw motor, it’s time to connect it to the sprocket. Take your worm gear reducer and attach it to the chainsaw motor. Then, take your 16-tooth sprocket and place it onto the worm gear. Once secured, attach the V-belt to the motor’s pulley and connect the other end of the belt to the 16-tooth sprocket. This will transfer power from the chainsaw motor to the bicycle. It is important to make sure that the belt is tight and properly aligned for optimal performance.

Step 9: Connect One-Way Sprocket

Weld Your One-way Bike Sprocket

Next, weld your one-way bike sprocket and 24-tooth sprocket together. This will allow you to pedal backward as well for braking purposes. Make sure to weld it securely, so it doesn’t come apart while riding. Otherwise, it could cause accidents. It is essential to have a functioning one-way sprocket for safety while riding. You can also install a handbrake if you prefer, but the one-way sprocket is essential for this setup to work correctly.

Step 10: Connect One-Way Sprocket to Rear Wheel

Attach the welded one-way sprocket and 24-tooth sprocket onto your rear wheel. Make sure it is placed on the same side as the chainsaw motor you attached. The sprockets should be aligned with each other for proper functionality. Once everything is securely in place, you are ready to take your homemade bike with a chainsaw motor for a test ride! But remember to always prioritize safety and wear protective gear while riding. Have fun with your new motorized bicycle!

Step 11: Tweak and Adjust

As with any DIY project, there may be some tweaks and adjustments needed to get the best performance out of your motorized bicycle. You may need to adjust the alignment of the sprockets or tighten/loosen the belt for optimal power transfer. It is also important to regularly check and maintain the chainsaw motor and other components to ensure safe and efficient riding. Experiment with different gear ratios for varying speeds and have fun customizing your motorized bicycle according to your preferences.

Following these steps on how to put a chainsaw motor on a bicycle, you can easily transform your regular bicycle into a motorized one using a chainsaw motor. Not only is it a fun and unique project, but it also allows for an eco-friendly mode of transportation. So get creative and start pedaling (and sawing) away! Happy riding!  #End of Document
