Morgan have built a new 3-wheeler. I don't think it'd be too handy to have everyday like, but I'd like to have a drive of one. Anyone driven anything like this? Is it fun? Maybe I should go on the lookout for a Reliant Robin and take it for a test drive!

hi Bobin

Chap I worked with before he retired built a LOMAX kit car, (I work in a drawing office for a living so you come across some wonderful people some slightly strange!!!) it was based on a 2cv with one rear suspension arm/wheel removed and the remaining one reversed to make it central. Original metal body removed and a purpose built fibreglass body attached, looked very much like a Morgan with its 2cv air-cooled engine. The carb used to freeze in the winter and the bearded owner used to say it was just like a proper classic car.....(he also owned a reliant scimitar 3litre and a herald estate.....he said he didn't like paying road tax....and by having 3 cars there was also one that used to start in the mornings...(also used to use flying glasses driving the lomax....no windscreen!)

anyway back to the 3 wheeler. when he left he gave me a lift to the pub in the lomax, I've never grinned so much in my life (had a lift in a FORD RS200 once,,not a RS2000 but the ex-rally 200....amazing noise and smells,,,) the lomax with its open top and stares from the school kids...was a laugh a second.....would I like to have a crash in one...lets not think about that.....

oh by having a light weight 3 wheeler you could get away with only paying motorbike road tax rates...and his other cars being pre-1973 where all free...

Paul.

nice thread though.,...bought back some memories......

oh the IT MANAGER here has a http://www.grinnallcars.com/scorpion-III-sports-car.html like the morgan and lomax 2 wheels at the front and one at the rear., with a hoofin great motorbike engine,,,search on the net....it goes like stink.....(in the dry....) hes single and loves his toys....

Morgan Three Wheeler - SlidingPillar

I've got one built in 1930. Puts a grin on your face driving it.

With only 42bhp, nowhere near as fast as the new one but even my vintage one can surprise owners of modern cars under the right circumstances. Reliant Robins - have them for breakfast... (They do not handle at all, can't do corners).

New one will be as easy to drive as a current car, mine isn't, with hand throttle and advance and retard, no sycromesh and a right hand gear change. Oh and the front brakes are a lever to pull, footbrake is rear wheel only.

When I was a kid my dad had one of these

No doors - only flaps. No locking or security. Rear "seats" were like hammocks strung across the back. Two-stroke engine

And as I recall, the engine was in unit with the front wheel - so there was no reverse gear, just rotate the steering wheel so that the front wheel pointed backwards - or have I remembered wrongly?

Correct, there was no reverse gear.

You couldn't quite turn the steering wheel as much as you suggest, but its turning circle was probably measured in inches, so lack of reverse wasn't a problem. Also, the whole thing was so light you could literally pick it up the front end and just swing it round.

three wheeler - TeeCee

Maybe not. There's a world of difference between having the two wheels at the front (goes round corners) and the two wheels at the back (falls over its own front corners at the slightest provocation).

Having driven both types, in handling terms the former is terrifyingly great fun, the latter is just terrifying.

I can't agree with you TeeCee. The Bond 875 was very stable en.wikipedia.org/wiki/Bond_875

Compared to my first: en.wikipedia.org/wiki/Scootacar Which would lift a front wheel at the slightest provocation and even the back if you braked too hard. It had a second set of points and the engine was started backwards to reverse - I once got it into third, but the steering was hairy.

I was a passenger in a three wheeler once which was more fun than Alton Towers! I love the stories about how miners in Yorkshire used to fill one side with tools to stop it rolling over etc, i dont know if any of that is true or not! LOL

Give me two full contact patches of rubber on the bit controlling which way it goes any day thanks.

I am afraid that I cannot find a single article on that vehicle (including the wiki one) which does not include the words "unstable" or "precarious" in its description of the handling.

Sounds like it was a bit quick for its time though, Surtees broke the Brands lap record for saloon cars in one. But then he was a motorcyclist and used to nursing things shy of the odd wheel or two round corners......

I saw the Peugeot EX1, an electric concept car at Goodwood. Not a three wheeler, but it looks like one as the back two wheels are close together. I thought it was beautiful with that black and gold colour scheme.

Would any of our technical experts care to comment on whether 2 at the front, 1 at the rear (Morgan and other 30's sports cars, and most 50s bubble cars) is inherently more stable than 1 at the front, 2 at the rear (Reliant, Bond)?

From what I've read, Reliants were generally unstable but the Bond 875 and Bug were a lot better. Maybe it's to do with the individual suspension set-up?

three wheeler - Bobbin Threadbare

Yes - good point Avant.

three wheeler - unthrottled

One thing we can be certain of is that 3 wheeled cars don't wobble!

2 wheels at the front is inherently more stable since the centre of gravity is virtually always over the front axle-especially during cornering and braking which is when instability is a problem

three wheeler - Armstrong Sid
I'm not a great fan of Mr Clarkson and some of his Top Gear antics, but some months (maybe a year) ago he did a feature where he drove a Reliant Robin and demonstrated how stable it was.

It was one of their better efforts

2 wheels at front, with one at rear, and engine at front leads to a more stable car than the other option.

three wheeler - unthrottled

There could be more than one option-Nascar would benefit from a configuration of 2 wheels on the right hand side and one on the left since there there are only left hand turns and the loss of a left hand front wheel would result in reduced weight and rolling resistance but no loss of lateral grip...

three wheeler - Avant

Now there's an original thought. I can imagine Tom (the inventor) on The Apprentice trying that one on Alan Sugar.....

three wheeler - jamie745

But Avant, that'll have to wait until after he's perfected the "Emergency Biscuit".

That's called "motorbike sidecar racing" ........

three wheeler - Bobbin Threadbare

Ohhh now you've lost me with this Apprentice drivel!

three wheeler - unthrottled

But what happens when you turn right in a sidecar race?

Wouldn't happen in the US - they only go one way round !!

You are very close there. When Indycar was a purely Oval affair, Lotus produced the 38 with longer suspension on the right than the left. Basically a car designed to turn left. A lot. Quickly.

IIRC, the Indycar people went through the rules with a fine-toothed comb looking for an excuse to ban it and failed to find one. "Street" circuits were introduced to the sport shortly afterwards to stop any other devious British SOBs having any funny ideas.

Nascar solves the problem by having rules that dictate the maximum length of the driver's moustache and exactly how many cup holders a car is allowed to have.....let alone wheels.

three wheeler - unthrottled

I know rules have to be there to level the playing field but it would be nice if the left leeway for lateral thinking. I forget which motorcycle manufacturer used oval shape pistons to maximise valve area-and it was very successfu-until it was banned. This sort of stuff might prove to be more useful on the road than trying to use single cystal conrods to wind another 1000 RPM out of an already screaming engine.

I think it was Honda.

Honda NR: en.wikipedia.org/wiki/Honda_NR

I was around at the time of the Owen Greenwood Mini special: www.britishpathe.com/record.php?id=44109

It was promptly relegated to the back of the grid while they re-wrote the rule book.

three wheeler - unthrottled

Cheers for that! I remember reading about it and not filing the reference away (like so many things). I thought it was to get round the rule that defined a maximum bore centreline distance which was designed to cap the valve area-but looking at that engine, that wouldn't help. Wasn't there an inline engine with oval pistons with the semi major axis Perpendicular to the crank centreline?
