16″ wheel prototypes (trike and quad!)

I felt compelled to share the following pics of prototypes I may work on in the future. My next model is going to be 16″ wheels. After working on the heavy 20″ back wheel and seeing people on scooters that seem to have 10-12 inch wheels, I’m going to stick with 16 inch wheels moving forward!

The pics below are for a 12-16 inch wheel design. In case you’re wondering where are the spokes on the wheel, they are “covered” with yellow wheel covers.

The quad design is below. I have a top view (second pic below) to show that the construction is similar for the front and back of the frame.

To make it easier on my eyes, I changed the color of the square tubes.

Continuing with trike …

I’ve been busy within the past 15 days. I believe I found a solution to have the “leg” stand on its own. Now the problem is getting it to come to fruition. I have a video showing my progress below, but notice how the trike crawls.

In light of the video above, I am working on making a super stable structure to support the back wheel. The funny thing is, I thought I would be able to bang this project out (literally) by using #12 2″ self tapping screws. Those screws are strong! I had to figure out how to make them stay straight while using them because they can veer quickly and finish off on a diagonal! I want | and get / ( I want straight and get diagonal). If the screw goes on a diagonal, it shifts the square tubes I want to attach.

The drill that I was using (a Black and Decker NiCd) decided to quit on me today. I think the batteries are completely drained from working on the trike. I owe someone for the drill now… I bought “Genesis” (a 12 volt cordless LiOn) today from a hardware store in lower Manhattan and was excited when I was shown the power of it (the project continues). Then I used “Genesis” to make a few holes and was trying to figure out how it works (when I say works, I mean efficiently). I read the instruction manual, but there’s nothing like test trying. The battery is lithium ion which smokes nickel cadmium out of the water. After a few holes, it got tired on me too! I’m thinking a drill press is necessary for this project, but the whole point of the project is to be able to get anyone who has simple tools to make this trike. Maybe I need to learn how to make a drill press?

PS. I found a bike stroller by the side of a street! I grabbed it up quickly and now I have 2 16 inch bike wheels! These are the ideal wheels! I already made a design for the 16 inch wheel trike. I believe this is the ideal trike to make since the wheels aren’t that heavy and that would make for an easier build.

Tri to Quad?

I’m noticing that it’s becoming strenuous to make this project a trike. A crazy saying even came to mind: if I can’t make this thing stand on one leg, I’m going to give it another. I had March 15 as a deadline for completing the trike as well as having a coroplast shell for it, but that’s not realistic. I had to change the rear of the trike since it wasn’t able to support my weight and utilize the electric motor. The modified rear is almost complete, and I still notice that the trike tilts upward from the back to the front. This shows that the weight distribution is not at a recommended “70-30″, but perhaps 90-10.

I already have an idea on how the quadcycle would look like and even have the pieces ready to cut and assemble. After one more try on making this a trike, I plan on converting it to a quadcycle. One problem is going to be that once it’s complete, people may think it’s a go-kart, and it’s not a go-kart. Another problem that may become an issue in the future is that there are no pedals. I don’t see anywhere to put pedals and a bike chain, unless I make some new construction for the bike chain to turn the front wheel, and be flexible enough to allow the front wheel to turn without breaking or unmounting from the sprocket. I have an idea of having a few sprockets that are aligned in different directions that pull chains in different directions. In NY, there is still the concern regarding electric motors on a bike, and as far as I know, a bike must have pedal assist and not be completely electric driven.

One last thought: I have a 26” wheel bike frame that I have sawn in two to be attached to square tubes in order to make another trike. I’m not sure if I should continue and make that into a trike. Well, like I say: One play at a time.

I made trike music, and so here are the lyrics to the rest of the “One play at a time” mentioned above:

One play at a time

Because the game is on the line

Everything will be fine

If you follow this rhyme.

One day at a time, one play at a time, one game at a time, because the game’s on the line.
