The Northwest Vintage Speedster club has a growing gallery of speedsters that would each scale well to Cycle Kart proportions. I am especially fond of the elongated tear drop back ends and any transverse leaf springs in the front. Be sure to click on each of the cars to see additional pictures. Enjoy!

I happened on Project Streetliner, a scooter based commuter vehicle, that I thought was worth mentioning here since it is “sorta” like a Cycle Kart. It is home-built, so in that capacity, it embraces the “figure it out and have fun doing it” mentality of Cycle Karting. The front end would also look nice on a Cycle Kart, especially if someone would tackle a wishbone suspension like the Streetliner, while maintaining a vintage look. I am using an independent swing arm suspension, but utilizing a single transverse half elliptical leaf spring, so it will be in front of the body.
UPDATED I switched the video to a slightly longer video Don posted.
I have posted pictures of Don’s build progress earlier and now he has video of his first ride!
Congrats Don, it looks good. It also makes me want to finish mine.
I had the opportunity to buy a Comet TAV2 Torq-A-Verter CVT a year ago when I first started dreaming about Cycle Karts, but I didn’t and now they are impossible to find. I have frantically searching for the TAV2 unit or some alternative.
Steve suggested Max-Torque. They have 3/4″ diameter units in stock, however I need a 1″ diameter for my application since I’m using a 8 HP Tecumseh engine. Some places anticipate stocking knock-off TAV2 units in the coming months, but I doubt the quality or the likelihood of delivery. I looked at some other options, like CVT units from 250cc scooters, but once more faced the 1″ diameter issue.
I found CVTech-IBC, in Canada, and it looks like they are the best bet. They offer many diameters, including the 1″. They also have twice the gear ration range of the TAV2, but they cost twice as much as well.
Has anyone had much success with only a centrifugal clutch? The official CycleKarts.com specs use a torque converter, so I’m hesitant to try it without one.
I purchased my cycle kart engine from an online vendor that said it sat on a shelf for several years. It had never been started, but I was still a little nervous that it would fire up. It started on the fifth pull and ran well, although I did adjust it to idle a little faster.
As my frame is no where near completion, I mounted it on 28″ long 2X4 boards for testing. I let it run for a while to get warm before giving it full throttle. I weigh 210 lbs and was standing on the boards and couldn’t keep the engine still when I gave it full power. I’m very excited to get moving with my build, but still need to find somewhere that still has a TAV2 for sale.
I just purchased a differential rear axle that I hope to modify for my cycle kart. I say “hope” because the axle is actually from a zero-turn-radius walk behind commercial lawn mower. It is too short and I am concerned that it won’t be able to withstand the speed and abuse, but if it works it will work well. I also anticipate creating an attachment to lock the differential if I ever find myself using the cycle kart in looser dirt where a live axle would perform better.
