In the first image, my students are using a hand drill to drill a 5/8" hole through 1/2" steel rod. Next year I'm asking for a drill press. :D
The second picture shows the 1/2 inch bar welded to the bottom of a shortened fork tube and mounted to the front wheel.
The last two pictures show...
For the drive system, we are using a #35 chain from the motor to a center shaft, and then a single speed bicycle chain from the center shaft to the rear wheel. To mount the rear drive sprocket to the rear wheel we used the 6-bolt pattern for the disk brake (opposite of the normal drive gears.)...
The local bike shops either didn't have someone who could build wheels (lace the spokes) or were backed up for weeks and could meet our time frame. Time to learn something new! My students did a great job building the wheels. They came out straight and will need very little adjustment at the...
Attached pictures show:
-The home made drive we will be using. The astroflight motor mounts to a frame which will also hold the 3/4" shaft. The motor has a 9 tooth chain sprocket and the shaft has a 40 tooth sprocket. The large sprocket is held in place with clamps and prevented from rotating...
Some pictures. Right now it is just a fairly standard atomiczombie.com warrior frame. I also found a pic of students working in the shop with no faces visible.

A couple of comments about the atomiczombie.com plans.
1) The plans are amazingly detailed and step-by-step. Perfect for a first time builder.
2) I e-mailed the side owner and asked about using the plans for a college course. I was prepared to require each student to buy a set of plans as...
Before I knew that I had financing from the school, I was thinking I'd go with a hobbyking motor and esc combination. One of these motors possibly?

Hello,
My name is "Dr. Ted" from a college in Georgia. Because of FERPA, I'll be using only my first name and ask my students to only use their first names as well.
We are going to build an electric tadpole trike. We are 5 weeks into the build and expect it to take at least until December...
