Hmmm so it must look like mine then
There is no cable to put it into "bike mode." Maybe that cable is a decompressor valve. There were leg shields available for those, and that's what those pegs must be mounted on. I've only seen maybe 2 pictures of the leg shields as they are ultra rare, and I don't care for them really.
Here's the place I shoip for parts, and the only place I know of in North America.
"Motor West Inc":https://www.motorwestmotorcycles.com/shop/
Also you can shop in The Netherlands here...
Not really any mod parts for them. I ride mine daily, even through the winter. It's my favorite moped ever! Pedal backwards to engage the back break. I have been through mine and others like it, so if ya need some questions answered I will do my best to answer them for you. I also have a manual on CD. It is for the earlier version, but almost exactly the same.
Please don't part it out. These are sought after bikes. If you don't want it, someone else will. If you ride it for a day, you will never want a different one. Oh, and they do about 35mph top speed if tuned right. Mine's doing about 32 or so right now.
I hate the original seats, but you can get replacement rubber covers for those at MW. I just use old Schwinn or similar bicycle seats, as they fit.
About the only thing I see on your list that may be hard to get will be the shrouding. If it's just the vent cover, you can get those from Rinke, at Rinky Toys. Every once in awhile a motor or parts pops up on ebay. I usually look under "Allstate Moped."
