Irev might be about to have a "crisis"

AMERICAN innovators Lit Motors have been punting out computer generated pictures of their self-balancing, electric powered, fully-enclosed two-wheeler for a while now. But this is the first video showing the thing in the (bare) metal and in action.

Where it was once simple to define what was motorcycle and what was car, our lives here at Visordown are being made increasingly hard by machines like the Lit C1. It's clearly not aimed at traditional motorcyclists, with a far wider target audience of eco-conscious commuters in its sights, but it has got two wheels and motorcycle-style dynamics (i.e. it leans around corners) so arguably it falls under our remit.

The Lit C1's USP is the fact it's got built-in gyroscopes, spinning at 12,000rpm, to help keep it from toppling over. Just like the gyroscopes you might have played with as a kid, as long as they're spinning they'll balance, automatically correcting to account for movements and assuming the right amount of lean in corners to counteract centrifugal forces.

As shown in the video, they even mean the C1 can be reversed like a car, still balancing quite happily in what looks like blatant defiance of the laws of physics.

Of course, we'll still have to wait to see if Lit's promises of a 120mph top speed, and 220 mile range from an 8kWh battery can be realised, let alone whether it can be done at anything approaching an achievable price – Lit hopes the first models will cost $24,000 (£15,500) and that prices could come down by a third once production is ramped up.

It either has no suspension or the body work needs to be higher to clear the tyres.

I dunno....some fool will take this and add some more wheels to it and call it a 'car', then everyone will buy one, and where will be then??

The problem with all that bodywork and batteries is the weight which will mean very big tyre bills.

Yes very suspect looking and a steering wheel instead of handle bars is a mistake.

It's a fun idea though we'll never see it on sale.

What I really want to know is what's happened to the Quadro 4d? That look'd like a concept that could actually reach production

I've been following the development of this for a while. It's not inspiring paroxysms of lust...

As with all these concepts, seems like a good idea, throws out loads of speculative numbers.
However, while the ergonomics and basic concept seem sound, I can't see how they can find room for the battery packs AND the gyroscopes, and deliver the speed and range they promise. Not with todays tech.
The gyros seem like a great idea, but unnecessarily complicated compared to self-deploying balancing wheels for standstill use and a pending liability issue going round corners - what's the transition speed? At what rate can you slow and/or stop the gyros? What will be the lifespan of the bearings and gyro motors if they're ramping up and down in stop/start traffic? They can't be steady-state on for cornering as the cumulative gyroscopic rate of a leaning vehicle in motion is in constant flux based on the angle of dangle, the road speed of the wheels, the acceleration or deceleration of the vehicle and the mass and the centre of gravity. All of which constantly vary in a road going leaning two-wheeler. No videos of the concept show anything other than crawling speed and when journos have tested the proof of concept they haven't got beyond 10mph. Unless this doesn't lean around corners? Which might explain the steering wheel... but not motorcycle wheels and tyres.

Next, the design of the front end is very suspect from an aerodynamic point of view. That vestigial front mudguard does not enclose the wheel, so the `forward rotating` top half of the front wheel is adding drag factor and spoiling the air flow. A front wheel MUST be enclosed to provide reduced drag and optimised air penetration for the wetted area. Enclosing it also means you don't need anything pretty to control it, so the HCS system can look like a bit of rebar with a rusty spring and nobody need worry. You could also move the monocoque forward, reposition the driver with feet closer to the wheel spindle and have more room in the back for the vast store of batteries you will inevitably need. If a Dutch geezer with a pedal cycle fetish can figure it out, what's with these Yank `geniuses`?

But at least it's eschewing conventional thinking... If they'd like to invite me to test the 0-60 time, the 120mph top speed and the 220 mile range I'd be happy to fly over.
As the Marketing Director of a world-leading environmental company I'd be only too pleased to apologise for the scepticism. :lol:
As an engineer with a rather large amount of experience in the field I suspect i won't have to... :)

I still see the future with this class of vehicle, but forget the gyros, put some holes in the floor, add self-adjusting, self deploying hydraulic feet and put the new X10 350 engine in it then call me again... :ugeek:

Dutch?
Thought it was Swiss?

The three wheel Carver (which went bankrupt) was Dutch ;)
