Very cool project. Especially mixing in the arduino... But like Jerry said don't run with scissors, put a helmet on keep your fingers away from the prop!

Well for those of you that choose not to use facebook, Im am posting the mods I did to the scooter so far.

Here is a bearing support the will hold onto the end of the motor shaft. I dug thru the old motor parts bucket and came out with about 5 of these bearings. Clean up and picked the best one. Its from one of my MAC 67/84 motors.

Shot of the back side. I plan to bolt it to a flange that will be welded onto the frame. It will have slight adjustment to get the alignment right.

Bracket and bearing mocked up.

I ordered a larger rear wheel. Went from a 5.5 to an 8 inch. The sprocket is 5/8" wider from center line and need more room inbetween the rails as well.

I cut out the motor mount and got out the old portaband.

No more rear end. I turned some plugs that will go into the tubes.

I was able to use my conduit bender to bend the tubing out a little since I only needed 5.5 between the wheel plates. The pics looks off a little but it is all centered up.

I end up cutting slots on the bottoms sides of the tubes for about 2". These will accept the wheel plate that I plan to weld into them.

Forgot to take a pic of plates. But here a shot of the plates/tubes being squished together in the vise. It started to split a little on the top of the tube. Nothing the welder cant fix thou.

I had to put a slight offset in the wheel plates. Did not quite have enough room in between. Its all mocked up and looking pretty good.

All until I look at it from the side. With the 3.5" stretch in the rear and the 6" stretch in the center that I have planned, I dont think I have enough ground clearence. Its only about 1.25 in this shot. Going to need to drop the back end another 1.5 at least. I dug thru the scrap pile and found some plate that is the same size thickness as the ones I already made. Now I will mkae new ones that are taller dropping the rear wheel.

I plan on stretching the front fork as well to keep the ride level.

We have been doing some programming with the audrino board. We plan on having 3 modes. Slow, medium, and death machine!!!!!! Matthew can adjust how much throttle is given to speed control to limit the speed. Also went into the speed control and softened up the start within Castle software. Should help with the wheelie issue. Well thats all for now. Need to finsih up a bunch of customer projects before I can get back to this one.

Dang! Just watched the youtube clip... "scary".

Made new rear plates with 1.5" more drop.

Had to well back on a piece for the brake assembly. Machine a nice slot after I rough cut it.

New plates ready to go into the frame with block to keep them aligned

All clamped down on table ready for welding.

All welded up.

I welded in new motor mount plates and cut out the cross plate that held the battery box. Keep the bottom rails. These will get welded back to new plate after the center section stretch.

Cut it in half. Ready to get bigger.

All pieces together and ready for welding.

All done and cleaned up.

New back cross plate add to support battery box and welded the bottom rails to it as well.

We put the scooter back together did some testing. It handles much better but is a little squishing in the middle. Matthew is 150 and was flexing the frame a bit when he did some bouncing on it. If I put my 213 pound butt on it, we might have an issue. Time for some beefing up.

Welded on some 3/4 rail all around the sides of the scooter. It has some cross braces as well the give more strength. Once I have the aluminum deck down on it should be able to take me no problem. Also got the back deck mounted up. Not sure if I am gonna put some struts on it yet. Once I add the gussets that the deck screws to, might be strong enough. We shall see.

Stretch the forks and mount the motor tomorrow.
