I decide to start a new thread since the Delta is basically all new. The frame is thin wall 1/16" inch and a half square tube. It will be fully enclosed, to that I just picked up 3 four foot by eight foot sheets of yellow coroplast. The frame is just the rear platform which holds the wheels and seat connected to the front boom which holds the crank and pedals and the front forks. Body work will be shaped by 1/2" electrical conduit. I have a conduit bender and it will enable some curves to the body. Just need to sand the zinc coating off before any joints are welded.

So far just the rear platform has been made and mounts for the rear wheels made. It has a direct drive motor right rear and that required mounts to be built for 2 torque arms. Also separate mounts for the rear disc brakes. I used to prefer cardboard for any bracket templates but on this build found a scrap piece of coroplast is way better. Its very easy to use a marker for the general shape then use scissors to finalize it. Any mounting holes such as for brake mounts can be made in the coro by a hole punch and the coro will then take a small bolt. Using this method.

So far the brackets to hold the rear wheels and the disc brakes have been fabbed up. Also the rear direct drive motor needs a torque mount on both sides and they have also been built. I will get a picture up in a couple days.

A bit more progress. First pic the frame is upside down, second it's sitting right side up and shows the seat mount, third with the seat mounted. Now working on the front fork/wheel setup.

Got the steering set up now. Next step will be to add the framework that will hold the coro panels. I decided to give it a 62 degree head angle for straight line stability

There is quite a gap twixt pedals and front wheel , do you need that ?

being in the UK we have small houses.sheds & cars and need stuff as small as possible ;)

Look like your handle bars tilt forward is that for ingress ?

I always like this Finnish delta , he has more car like steering.

Sadly it would never get through the street obstacles I meet every ride.



he has car like steering to the fork hardware ?

You are right about the gap between the pedals and front wheel. I actually shortened the wheelbase by close to 9" from the previous version. I was aiming for an 8' overall length to make the best use of the coro sheets for the upcoming bodywork. The wheelbase and the slack steering head angle are meant to provide a nice stable ride. The bars are adjustable but its a set it and forget it system, they take 2 1/2" wrenches to adjust the angle. A friend made that for me when I tried Brads high racer plan and I keep recycling it. Things are a bit bigger here in Canada, we have a bit more room. A lot of my city rides are from 40 to 60 km.s long and the width of this build means it will fit pretty much everywhere. Thanks for the photo of the Finnish delta, always nice to see stuff like that.
