Upright deltas are inherently barmy if you ask me, so why not throw a little leg-brake-steer into the mix?
That is where the burn marks on the back of my shorts come from. Although braking with a leg is out of the question, it hurts too much as I know from riding 1960s/70s trikes which were a bit shorter in the chainstay. The bum braking is just by accident - the perfect day with the perfect corner and my backside is just touching the wheel which in turn is just touching the road, you can just feel the wheel stalling under your backside ----- absolutely fanbloodytastic.
Like most of my generation I grew up with single wheel drive. It is not usually a problem because the left wheel is driven so it compensates for camber to a degree. Climbing is interesting. On a steep climb you can get out of the saddle and risk wheel spin, even though you might be positioning your weight to favour the drive wheel; or you can gear down and sit down with your weight well back. The latter approach means that the front wheel is travelling very light and the offset drive will cause it to drift to the right, so periodically it is necessary to lift the front wheel and put it back where it should be.
I learned to ride on fixed, as an impoverished schoolboy it was the cheapest way. I used to ride it to school (sixth form) and all my school mates who tried it found it easier to ride backwards.
In 1986, after 18 years of riding single wheel drive, I got my first two wheel drive (not diff) Longstaff and proceeded to forget all the little tricks that you learn to keep a single wheel drive going where you want it to. Then in 2003 I bought an old single wheel drive which was sharp reminder. I currently have three two wheel drives and one single wheel drive.
