Attaching Wheels & Axles: A How-To Guide

In summary, two 14" wheels need to be attached to one axle, and a free hub needs to be attached for the wheels to keep rotating when the bike is stopped. If you are using a chain sprocket design to drive the axle, you can just ratchet the pedals. An overrunning clutch system can be used if you are using shafts. The steering and handling on the bike will be interesting.

I've got two 14 inch wheels and now I need to attach them so that they rotate on one axle. I also need to put a free hub so that when I stop peddling the wheels keep rotating.

How would I do this. I really need to know even if it's a stupid question.

I don't really get what you are saying. Are those two wheels on the axle driven by pedalling? What is it you are making?

If you are usign a chain sprocket design to drive the axle, you can just ratchet the pedals.(means you can't go backwards though)

You could also use an overrunning clutch system if you are using shafts.

Well, I'm sort of tying to make something like a bicycle but instead of one back wheel, it's two wheels attached to an axle. I know that's pretty much a tricycle but I think that they have pedals at the front wheel. Instead I'm trying to make something like it except the pedals control the back like a bicycle.

I'm just doing this for fun. I wanted to do this from scratch but I guess it helps telling you what I'm doing. So if you understood what I meant can you help me?

Then its very easy to do. Just use the existing chain sprocket system, it'll already have a ratchet on it.

It'll work exactly the same way as a bicycle on with 3 wheels. :DI can see the steering and handling being... interesting on it.

I'm sorry I'm sort of an idiot.

I have two wheels but nothing else. I'm guessing I need two hubs, some metal rod I can call an axle and a chain sprocket system. Do I buy the chain sprocket system or what? It's just that you said use the existing chain sprocket system that confused me, because again I only have two wheels.

By the way,

If it helps I just got into this today when I found two wheels that I bought but never used. Before today I had no idea what a hub, racket, or a chain sprocket system. I just googled as i went. So go easy on me :shy:

I just meant the same type of system. Of driving sprocket attachec to the wheels and wheel gear cluser attached to the axle.

You'll probably have to buy new sprockets to build a rear cluser that fits the axle. Or you could try to jury rig the existing cluster to fit.

A third option is to use the existing gear cluster from the bike, and mount them somewhere convenient. Have them rotate a shaft with a second sprocket on it and run this to the rear axle with a 1:1 ratio. This means you only need to find 1 sprocket to fit the new axle, but it adds complxity (and therefore unreliability).


Ahh a layperson :D, in that case if there is anything I gloss over, or you don't understand or whatever just let me know and i'll try to explain it better.

Please note I am a dreadful teacher, so you'll have to bear with me.

I've decided that instead I'm going to make one wheel in the back and two wheels in the front. I think it'll make it simpler. By the way, just to let you know it's not going to be ridden like a bicycle.

I just want to know if it's a good idea to steer with two wheels like a car with one wheel in the back.

It's definitely better to steer with 2 wheels at the front, it gives cornering stability.

Normally in faster turns you lean into the turn with 1 wheel, which obviosly you can't do an a tricycle.

Also 2 driven wheels from 1 solid axle had the effect of not allowing the wheels to turn at their own rate when going torund a corner. This means you'll get scuffing of the tyres.2 steered wheels presents fewer handling problems than 2 driven.

Try Googling 'pedicab'. Wiki has a starter article, but you'll need to search elsewhere for design specs.
 

FAQ: Attaching Wheels & Axles: A How-To Guide

How do I select the right wheels and axles for my project?

Choosing the right wheels and axles depends on several factors, including the weight of your project, the surface it will be moving on, and the speed and distance it needs to travel. Generally, larger wheels with thicker axles are better for heavier projects or rougher terrain, while smaller wheels and axles are suitable for lighter projects and smoother surfaces. It's important to also consider the materials and construction of the wheels and axles to ensure durability and smooth movement.

What tools do I need to attach wheels and axles?

The tools you will need may vary depending on the specific project, but some common tools include a drill, screwdriver, pliers, and a wrench. You may also need some additional materials such as screws, washers, and nuts. It's important to have the appropriate tools and materials on hand before starting the attachment process.

How do I attach the wheels and axles to my project?

The attachment process may also vary depending on the project, but generally, you will need to drill holes for the axles to go through and then use screws and washers to secure the wheels to the axles. It's important to make sure the wheels and axles are securely attached and aligned properly to ensure smooth movement.

Can I attach wheels and axles to any project?

In most cases, yes, you can attach wheels and axles to almost any project. However, it's important to consider the weight and size of the project, as well as the intended use. For example, if the project is too heavy, the wheels and axles may not be able to support it, and if the project is too small, the wheels and axles may not fit properly or provide enough stability.

Are there any safety precautions I should take when attaching wheels and axles?

Yes, there are a few important safety precautions to keep in mind. First, make sure to wear appropriate safety gear, such as goggles, gloves, and closed-toe shoes. Second, make sure to use the tools properly and carefully, and always follow the instructions included with the tools. Finally, be mindful of the weight and balance of the project when attaching the wheels and axles, and make any necessary adjustments to ensure safety.
