ill be excited to see this when you have finished, i love the auto union cars! thank you for sharing

Really Cool!

Damn that is so cool!!! I've been a bicycle mechanic for years and have always wanted to build one!!! So cool!! Please make some more videos of this project. Also check out Kenda tires. They actually make a 20×2.8 inch tire. That would be super cool to see some fatter tires on that thing! So awesome man!! I want one!

Most cyclekarts worldwide are limited to 17" wheels (18" for Edwardian types with artillery wheels) In the U.K. we have a limit on tyre (tire U.S) width of 3.25", the ones on mine at the moment are 2.75" but I have some 3.25" ones for the back if I don't have too much grip - which can be dangerous in a cyclekart - better to slide than to flip! Normal bicycle wheels are not good on a cyclekart as they tend to end up looking like a pringle very quickly, we use 17" motorcycle wheels from pit bikes or Honda cubs.

The way you created those double arches and bars reminds me of bad prototypes of the past theirs no reason to box in your legs that way and in the event of an accident you are going to be badly injured and hard to remove otherwise it's amazing

Thanks for the reply. As this is a cyclekart and therefore needs a body to be one, we do need to have somewhere to mount it. I appreciate your concern for my safety but leaving it as you suggest would mean missing out on all the fun with my cyclekart buddies... www.cyclekartsgb.com/

okay, where are the other 11 cylinders? Great test run!

Sucess indeed! Did you find the steering heavy with forward drivers' position?

Partial success @olonspeed, the steering was not heavy at all, I would say it was about right. Most cyclekarts have Pitman arm steering, mine has a rack with about three times the gearing of a Pitman arm set up. I have the same rack in my BSA three wheeler and it makes the steering a lot more predictable. I am running about 7 degrees of castor on both. steering weight difference is negligible. It goes where I point it very well :-) The lateral flex in the anti roll bars may prove excessive and I may need to weld in some lateral support before I am happy with it. I am taking it to a kart track with my cyclkarting buddies this weekend...

@@jimrawnsley Thanks for the update. Changes are inevitable in a new design, a few more upgrades and I am certain you will have it locked down.

Front wheels looked a bit wobbly in the video. Good cart though!

Yes, one of the problems I need to sort out. The lateral movement in the ARBs is too much, welded strengtheners needed. As a first test drive on a new suspension system, it was ok
