Building the Frame

 After playing around with a few different ideas for the frame, I decided to start with a solid wheel base. For the steering mechanism I am using the largest hinges I could find at Lowes. I drilled one of the existing holes larger to accept the bolt from the bicycle wheels, then bolted it to the 2x6 that acts as the front of the frame.

For the back of the bike I am using the existing suspension of a mountain bike and attached it with a large section of all thread to the 2x3s that run the length of the frame. The suspension rod is attached using an old satellite dish mounting bracket. I still need to check how true the wheels are and if they hold air, but the wheel base is now complete.

A simple weight test showed that it could hold me and my daughter without any problems. Next I need to get the pedals attached and the chain and idlers installed. I also need to finish building the steering mechanism, and reconnect the rear brake and derailer. Once a seat is installed I should be able to drive it as a recumbent bike, after that I will probably work on the canopy, and lights, then install the electric assist after the fact.

I am really happy with my progress so far. Hopefully I will have it fully enclosed and electrified by the time fall hits.

Let me know your thoughts in the comments below.

First steps: Gathering Old Bikes

I put some feelers out on Facebook and had 4 bikes donated by neighbors who were looking to get rid of them. Between the 4 bikes I got enough parts to make 2 recumbent trikes, which is the base for my ebike. I was fortunate to get two bikes with rear suspension. This will make for a smoother ride when I get the trike assembled.

For the frame I am using scrap wood left over from several other projects, including a small pallet. This is just a prototype so I can learn the basics, the finished model will be much more streamlined.

A New Goal- an enclosed ebike!

 

After doing some research into the laws governing Electric Cars and NEVs in my area, I discovered it was going to be a real headache to get something inexpensive for me to drive around town. That was when it hit me. I don't need a Tesla or something like that if I am only going to use the electric car for travel around town, so I started looking at alternatives and discovered a bit of a loophole in the laws for the state of Idaho. 

A Class 2 electric assisted bicycle is defined as having up to three wheels, it can go up to 20 mph without pedaling, but can go faster if you do pedal. It is not restricted in what streets it can be driven on, but must stay to the right as much as possible. These bikes can be enclosed making them usable year round, and may have blinkers, windshield wipers, headlights, taillights, etc... They are not required to be registered, have insurance, or a license, so even my 14 year old son, could drive it!

In August 2019, the state of Idaho passed a measure that defined ebikes as bicycles. That means they can be used wherever bicycles are allowed. This opened a whole new door of inquiry for me, and I started looking around at ebike options.

Some companies are already building enclosed tricycles like the one I had in mind. (See the video above) However, to order one and get it shipped to me was still going to cost quite a bit! So I started drawing up plans and making a parts list, and figured I could build a prototype for less than $500. The major cost being the 750 watt conversion kit and batteries.

The basic trike without the electric assist is known as a velomobile, and is a lightweight, aerodynamic bicycle alternative that has been around for decades. This part is relatively easy to build and can be made with parts available at local stores and thrift shops.

Next week is earth week, and I hope to have the beginnings of my electric car/bike in the works before the end of the week is out!

Cookies in the Solar Oven

Made some chocolate chip cookies in the solar oven last week, and they were fantastic! Our second batch didn't cook as well because we had some cloud cover move in. But we still maintained between 150 and 200 degrees F. Each batch took about 2 hours to bake.

With a solar oven you need to adjust the direction it is facing about every 15 minutes to maintain your maximum heat.

Lee Hite Biomass Briquette Press

Neat idea to conserve wood, or if you don't have a lot of wood at your disposal, you can use shredded paper, leaves, etc. to build up your fuel supply. Combined with a high efficiency stove, like the rocket stove mentioned in the previous post, you could cook and heat for a long time and never need wood. On their website there are diagrams for different shaped molds, including sticks which would be ideal for most rocket stoves.

Clay Rocket Stove

I have known about rocket stoves for quite sometime, but this was the first time I saw one made out of native clay:

Here is the rocket stove I built:



Solar Oven Redesign

Here is a redesign of my solar oven. After looking at how my parents set up theirs, these modifications seemed appropriate. It reaches roughly the same temperatures (roughly 175° - 200° F) without any insulation, so I imagine if I were to insulate the outside of the box now it would probably go higher and reach a more appropriate cooking temperature.

My previous design was precarious at best and difficult to use. The idea here is simple, and efficient.

Solar lights from a bottle.

Here is a nifty way to reuse bottles to make lightbulbs. They are using this in electrically strained areas around the world.

Electric Scooter Tune-up

Finally got around to fixing the electric scooter that had a blow out on us in Rexburg. I was on my way back home (5 miles south of town in Lyman) when the rear tire went out as I was going down University Boulevard to 5th West.

I checked the batteries to make sure they would charge last Saturday, they miraculously did after no use and no maintenance for 2 years. Then last night I pulled the rear tire assembly appart to find one tiny hole in the innertube. It was the tire wall that took the beating, so I could have had this fixed right after the tire went out. A new tire is $25 from the website (www.x-tremescooters.com, we own the x-360 model.) The brake needs replaced as well ($29), but that can wait. It is just over a mile to work with 2 uphill stretches on the way home. I will take it for a test ride tonight to make sure it will make it the distance. I am going to assume the battery life has been somewhat depleted as a result of its lack of attention and use.
