Here I look at what is already possible and remarkably different from our two-wheeled brethren.
Here are some concept bikes collected not very recently. Note the axle-less wheel: the hub is the same sort of size as the wheel. It requires fine tolerances and the precision makes them expensive; they won’t take bumps well. That’s now, of course - but look at the skatecycle which is in mass production. Look at the orbital wheel
, pictured with a Pirelli tyre and a red rear - this seems to meet the criticisms. I noted “Braking must occur at the centre of the wheel, which requires substantial energy and a complex brake structure. The Osmos wheel is a step forward, offering the possibility of mounting large diameter brake rings or discs. The grip can be located close to the ground where the forces act. The brake ring design with its peripheral support could lead to multiple ring brakes being produced in the near future.”

Zero bike - electric bike. review 2014
I found a pedal bike with no dirty stretchy chain (a shaft drive), no tyres to puncture (solid tyres, suspension) and so virtually no maintenance. Shaft drive has been available since 1991; solid tyres from Tannus go on your existing bike - not uncomfortable and worth a look, even at £50 per tyre. Attractive as a cold weather tyre especially. If you haven’t looked at recumbent bikes, do. They’re a tad slower, they can be a lot lower and very stable. I think for the ene
rgetic cyclist the ‘old’ way will still appeal, but others may prefer this. I didn’t like the consequence of being nearer the ground when in with car traffic. The ELF is a three wheel bike that is a compromise in several ways that deals with these issues, having electric assist too.
I found self-balancing bikes and motorbikes. Please look at the C1-from Lit Motors. it is an electric motorbike, with an enclosed cabin and gyroscopic balancing - more of a two-wheeled car than a bike, and
around £15k at the moment. See a BBC report and another video. It offers (I didn’t say deliver) 200 miles between recharges, 100mph, no helmet - this may be the way to go. Watching it reverse into the street is weird.
Similarly weird is the one-wheeled electric Ryno. Youtube video. It’s a mike, not a bike, of course. Different, is Kerry McLean’s unicycle - sit inside the wheel; I think he’ll be wearing his shoes out driving like that.
BPG’s Uno is in between and looks very good but doesn’t have range or speed. The link shows how it fits together. A real-life transformer?
This is another electric scooter, but with three wheels and the middle one comes forwards for higher speed. Its max is 35mph, its range is 30 miles. For now; would work well in China, for where it is aimed. You still have to put all the protective clothes on and you’d hate the cold and the wet.
For low speeds there’s things like the Segway, electric mobility scooter; one or two wheels and a platform to stand on. Other manufacturers include Freego, Freego max 20kph, 45km between charges of 2-4 hours. Segway similar. There’s a solo wheel self-balancing range too - no handlebars, one wheel - disconcerting, but also of carry-able size and weight. max 10mph/16kph, range 15-20 miles, 26pounds (12 kilos), $1800.
