This is a guide to building up a bike from parts. It should help you get the parts and tools you need to get you pedalling along in no time.
It assumes that you have tinkered with your bike, but are not an expert. Hope it helps! Insert the seat clamp, then the post. Grease the heck out of the part of the post that will be in the frame to keep it from rusting together.
Then put the seat on. I then clamp it in the bike stand using the post, but thats up to you Install the headset first. I install the cups using a large bolt, some washers and a nut. The presses it in to place. There is also another instructable I put on here that details the exact process for this step if you are not familiar. I bang it on with a adjustable wrench. Ok put the headset together, grease the bearings, put your stem and any spacers you are going to use on the fork and make a mark with a marker.
This is where you are going to cut the steerere tube. NOTE If you have a threaded stem, then just try not to cut it, make it easier, just use some spacers. So now you take that fork out and cut it about 3mm below the mark you just made. I used a steerer tube cutting guide, but you can use a zip tie to mark the spot and cut it with a hack saw. Remeber measure twice cut once, cause you can't stretch a steerer tube.
Now you have to drive in the star fangled nut. I thread it on the bolt. Then use a hammer and tap it in about 1cm. Ok, put it back together. Tighten the top cap until its snug, but not too tight. Then tighten down the stem. You'll check it later. Insert the bottom bracket. Grease up the threads. Don't forget it goes backwards. Start it by threading it in by hand.
Don't use the tool yet. Now its time to use the tool and tighten the bottom bracket. Tighten the drive side, then the non drive side.I've built a few go-karts over the years and I have a general want to share what I've learned about the process with others. A go-kart is a small vehicle with a simple design, a small body build, four wheels, brakes, and an automotive engine. As difficult as it looks, they are somewhat easy to build on your own. It will be a very interesting project for you and your family and friends.
You will spend lots of bonding time building something useful together. But before you follow the step-by-step guide below, be warned: Building one requires time, special tools, dedication, and money. If you're one of those people who really love to assemble things, go ahead and build your own go-kart from scratch.
Buy every spare part after hunting for the best price. An alternative to buying your own tools is to have an automotive shop fix the parts as needed. It might be costly, but its a real time-saver.
You don't have to clean the mess inherent in fixing your own parts, and you won't make noises that often annoy neighbors. You will need a special place for your project.
That place should be dry, roomy, and well lit with a concrete floor. You'll also probably be working on this project for three to six months, so a part of your garage is the obvious choice. Are you really ready to build your own go-kart?
Let's start and gather the spare parts you will need. Air-cooled engines are smaller and simpler, so they will do better for your go-kart. They also start-up more easily in extremely cold temperatures; they won't freeze because there's no coolant! The downside of air-cooled engines is that they're prone to overheating. Water-cooled engines are heavy-duty and they can keep running without the risk of overheating.
But the water system of this type of engine should be properly set up, or your engine could be ruined due to a simple leak.
How To Build A Motorcycle From Scratch With Not Much Money
The average horsepower for an engine is 8 HP, but 10 HP is desirable. With a 10 HP engine, you can create a larger gear ratio, so you will have more torque and your vehicle will be able to climb higher with minimum hassle. You can bring all the tasks that need professional attention to a reputable auto mechanic shop.
Never attempt to do something that you do not understand fully. Engine parts that need to be fitted and steel frames to be cut, drilled into, or welded together should be done with some expertise.
You just have to make sure that everything is done according to your specifications. If you have a welding machine, a steel-cutting machine, or any other type of machine, and you would like to try your hand on them while building your go-kart, be sure to wear protective clothing and gadgets such as a welding helmet and face mask.
You also need to work in a comfortable and well-ventilated area. The role of suspension in your vehicle is to make the ride less bumpy during long travels. Some go-karts have shocks installed. But since you're not driving your vehicle over long distances, you might want to skip the installation of any suspension. Eliminating suspension will also save you a lot of money. If you really want a softer ride, you have the option to put in big tires instead.
Second to the engine, steering is the most complex part of setting up your vehicle. The main role of steering is to keep all—both rear and front—wheels aligned and neither pushed away or toward each other. A durably constructed steering wheel is absolutely crucial because it gives direction to your vehicle. Steering calls for some expert handling, so have it assembled by your dependable mechanic.Are you looking for information on how to build a motorcycle from scratch?
Then, you are in the right place. With a little inspiration and a burning passion, you should be able to build your motorcycle. At this point, all you need to do is follow through to the end of this guide and learning how to build a motorcycle from scratch will come all too naturally to you.
Read on to find out more:. As a bike builder, your best finds will mostly come from salvage yards. Take a stroll through any motorcycle salvage yard and uncover the world of possibilities lying in wait. To build your bike from the frame up, you first need to know the design you are looking to emulate. After that, you will be ready to start getting the various parts you need and go right into beginning the build. Every motorcycle building expert agrees that the order you should follow while putting a bike together is as described below:.
After ticking off every item on the checklist, use the tutorial below to help you as you try mastering how to build a motorcycle from scratch:. If you are, for instance, building a chopper, you need to modify the frame by changing the head pipe joint at the point where it is attached to the top from rail smack on the front frame down tube. Another alternative is to change the body so that it is fat around the tires and long along the frame. Remember, modifying is a mock-up process that will have you putting different pieces together to get a better feel of how your motorcycle will end up looking.
After changing the shape, add the triple tree where you will mount your handlebars and shocks. Once the triple tree is in place, go right ahead and install the brakes, rear and front tire, and shocks.
Your frame will become a rolling chassis after it has working fenders, rear and front brakes, rear and front tires, front suspension, front wheel, rake, and the frame. Experts advise that you should space your tires evenly with the bike frame so that everything will line up correctly.
Read more about motorcycle tire. After adding your transmission and engine to the bike, you can now insert the first case — ensuring that it lines up perfectly with the transmission and engine. The primary drive should be the gear reduction system that will transfer power to the clutch and from the crankshaft.
Next up is the exhaust system — which will make your bike run legally and well. For this, all you need is a pipe. In case your design for it, bend the pipe, so it matches your up-and-coming motorcycle.
To do this, look for pipe bending and welding equipment. If you lack the skills or accessconsider outsourcing this part of your bike building project to a motorcycle exhaust shop. In this, you might need to use welding brackets where and as needed. Where possible, build the mock-up of your handlebars and gas tank simultaneously.
The reason behind this bike building advice is that the placement of these two parts will have an effect on each. While still on the bike, you need to ensure that you feel comfortable holding onto the handlebars. That said, there is no shortage of handlebars on the market today.Hello again everyone! In this instructable I will be showing you how to build a 79cc, 4 stroke motorized bicycle from scratch not a kit motor.
Let's get started! PS: sorry for the crappy quality video, I'll upload a better one at some point once I figure out how to do editing and stuff.
How to Build a 72Volt Electric Motorcycle
Before you begin, it is a good idea to check the laws in your state or country, as motorized bicycles are not legal everywhere. Here are a few links to help you out:. Affordablegokarts has an entire page dedicated to aftermarket parts specifically for 79cc predator engines. Rebel Gears makes high quality custom motorcycle sprockets, allowing you to specify tooth count, chain size, center bore, mounting bolt pattern, color, and more.
Custom Motored Bicycles sells a wide variety of parts for motorized bicycles, including a disc brake sprocket adapter. Here is a list of the bare minimum of tools you will need to have access to.
Other tools may be required depending on your situation. The first step and one of the most important in motorizing a bicycle is to choose a good bike to motorize. You can't just go slap a motor on any old bike and expect it to work, especially one as large and powerful as the motor we'll be using. A good bike to motorize has several key attributes, all of which must be fulfilled if the build is to be successful.
I have outlined these attributes in the following steps. Please note that I will not be going into detail on the more advanced bicycle repair stuff, such as how to replace a front fork or install a disc brake.
If you do not know how, leave it to the professionals at your local bike store. First, the bike must have a large enough frame gap to fit the engine we will be using, which is the 79cc harbor freight predator. This is a fairly large engine to be cramming into a bicycle, so as far as frame gaps go, the bigger the better. Remember that the pedals must still be able to turn after the engine is placed into the frame.
The frame must not be made of carbon fiber, as carbon fiber will crush and splinter if we try to mount the motor to it. Aluminum is not great, but it will do if you don't intend to ride it much. Be warned that if you do use an aluminum frame, the frame will eventually develop cracks and break from metal fatigue. Steel is great, by far the best.
Some specific frames that work well are the older models of the Trek main picture is of a Trek frame with lots of aftermarket parts, this is one of the bikes I will be motorizing for this instructable and the older steel frame models of the Specialized Stumpjumper and Hardrock.
Look for a 21" frame or larger if they exist. Bear in mind that if you find a good frame with a bunch of junky parts on it, you can often swap out the other parts. Picture 3 is of the red and black bike before I stripped it down to the frame and rebuilt everything. One of the most important features of a motorized bicycle is good brakes. Because you will be going faster, you need more stopping power than an average bike.
I'd recommend getting a disc brake for the front, however you can not have any sort of disc brake in the back, as the sprocket that drives the bike will be mounted to the disc brake mount.
In order to compensate for having normal although still good bicycle brakes on your bike, we will be setting up the engine in such a way that letting off on the throttle makes the engine act as a secondary brake.
Pictured is the red and black bike, sporting a top-of-the-line disc brake with a mm rotor. You will want to avoid using a bicycle with ram's horns or other handlebars with curved ends, as it will force you to use a thumb throttle instead of a twist throttle, the former of which makes your thumb get tired fairly quickly on long rides.
If you have a road bike and don't want to spend the money on a new frame, however, there are workarounds. For example, I have a motorized road bike which has a thumb throttle and also has the rear shifter converted into a second throttle control that locks in place.
The rear sprocket will be mounted to a disc brake mount on the rear wheel, so we need enough clearance that the chain does not rub against the frame this will kill a bike frame very quickly.Forums New posts Search forums.

There are 17 references cited in this article, which can be found at the bottom of the page. This article has been viewedtimes. Learn more An electric bike is a lot easier to build than you might think! All you need is a bike in good working order, a conversion kit, and a battery.
Using a conversion kit makes the process super simple and fast. And if you shop online to find the best deal on the kit and repurpose a bike you already own, this can be an inexpensive project. To build an inexpensive electric bicycle, you'll need a bike with front-disc brakes and wide handlebars, an electric bicycle conversion kit, and a or volt battery. Once you have your supplies, start by putting the tire from the old bike wheel on the new wheel with the hub motor that came with your conversion kit.
Then, attach the speed controller that came with the kit to the frame of your bike above the chain, and attach the throttle to the handlebars. Finally, connect the battery to the speed controller and throttle and mount the battery on your bike. To learn how to ride and charge your electric bicycle, scroll down!
