Thanks Punx0r glad you like the build.

Had to remake the battery boxes. Standing them on the side reduced the height of the box but made the particular awkward to work with, I just couldn't seem to get everything to sit nicely. Made a better job of the second boxes. Felt I could also do away with the middle piece and actually have them as two boxes. Everything fits better now.

Made of some of the cables and sheathed them with the stainless braid. There will be 6 sheathed cables running down the scooter. The sheath really improves the look, will look like some huge power cables, but actually inside is just control cables. The cables which come from the controller are made of to an amphenol plug. This will then go through a small box, basically there will be four sockets on the box. This will allow me to transfer from the controller plugs and configuration to send everything to their appropriate place out the other end. Have yet to make this box but won't take long as will only be small.

Still yet to mount controller or contactor. This job is really alot bigger than I imagine. I been up to 2am most nights soldering connections, 8 x 8 series batteries means everything is multiplied from my last build, used 20m of 1.5mm heat shrink, plus all the other sized heat shrink I have used. Nearly done a whole roll of solder too. I think I am about 75% through the electrics. Hope to have the project running by the weekend.

Here is a couple pics of where I am at.

So do I. I am sure I will one day. Another learning curve for sure.

Finally got this running today. This is seriously fast!!! I have clocked 46mph so far on GPS. Have not looked at controller settings yet to know what it's putting out as default. Not sure if I have hit WOT throttle yet. It certainly felt like 60mph not 46mph

I have an issue. When I made the test chain up I ground head of the pin and punched it out, but not all the way I then used the same pin to complete the chain link not using a split link. Now that I wanted to use the drive chain for test ride I used the split link, which wraps the tensioner too far around the knuckle. Its ridable but this is slight marking when the must of been chain rub because of this.

A longer arm to hold the bottom tensioner sprocket should resolve this, or a complete chain made up without a split link.

I have couple pictures of completed frame as I rode it. Will try to get video done, before I strip it ready for powder coat. Pretty much looking like a success. Obviously a few minor issue to iron out, but am pretty happy with the results.

Wow looks amazing!

I love this build so much!

Is their a reason the wires are facing out from the controller?

Is it possible to turn the controller around and hide the wires under the frame, between the battery boxes?

Just wondering!

Badass!! How is the handling? I like what you did here man, it definately is a grown up's stand up! 8)

Solid wiring job too, stainless lines look nice.

Thanks for the replies. Glad you like my project.

The reason for the controller facing outwards is because the high current bus bars would be pivoting into the suspension knuckle. It's quite ugly in terms of cable routing. The current leads I fed between the boxes, I am considering doing that with the two cables that come out of the junction box. I would have to secure the one that is sheathed and add insulation as the 400amp fuse holder is bolted to a plate I welded down there too.

It handles really well, the speed really gets the blood flowing. It's not as nimble as a goped, but I feel it is probably more easy to handle than the original 50cc, although I never rode that. All the weight is pretty low down with this so assume that helps.

Thanks for the replies. Going to be stripping the scooter this week to get it off to powder coat. At the moment I have not even looked at the controller settings but I know that I am getting 50mph on WOT and the acceleration is very fast!

I am sure there is head room in the controller settings to further speed it up, but wont try this until I reassemble the scooter. There is a few alterations I want to make to the tensioning system before I try this.

Got a quick video of my mate on the scooter, and also a little head to head with a 50cc. Which was pointless as there was no competition lol.
