So you'll effectively get a load of new torque when you shift up?

It's possible, it's just a little pointless. But if it's fun to shift gears in an electric car, then I could live with pointless!

I really don't know enough about all this sort of stuff, but this is how I see it:

Simple maths should state that if you have X torque at the engine with Y gearing you'll get Z thrust at the rear wheel?
Halve the gearing and you should double the thrust at the rear wheels I believe.

However, electrical motors can produce a consistent torque throughout a wide rev range, yet tend to use loads of electrical power if they go to really high speed so don't really 'need' gearboxes as a single speed will generally do the job fine.
Add in a gearbox and you may well be losing a load of the advantages gained - as you've now got a chunk more friction, moving parts to maintain etc.

I'm sure a lot of people will laugh at me for this but I'm seriously considering promoting Morgan to 'Favourite Car Maker' status.

I did many many years ago

I did many many months ago.

This is innovative stuff , coing from small English company...fantastic!!

well done Morgan

Love Morgans!, perhaps the last of the proper British sports cars.
Someone hit the nail on the head though, a great weekend blaster,
stored in the garage the rest of the week to charge up for the next
weekender. Some day, when the absurd price of proper batteries and motors come down, there will be a lot of tinkerers building EV's in the shed.
Some folks are doing it now but let's be honest the industry has a long way to go towards selling plug and play systems.

There is enough interest. Morgan please contact me.

Would seriously consider extending my Morgan fleet if this really works.
Man maths could work if the station commute cost drops to zero...
Have to keep the other one as it's not going to manage Geneva in one shot...
There, thunk I can convince mrs_t - thanks Charles...

Isn't a manual gearbox, particularly one taken straight from a petrol car, spectacularly badly suited to an electric motor?

The power curve for an electric motor looks something like this;



This smells like marketing rubbish to me.

I think it would depend on how the gearing is set up

[Vilhelm]

If the electric motor from that power graph was to be used for a car, surely the best thing to do would be to limit it to 8000rpm? Besides, an internal combustion engine's power graph would probably look like that past peak power, if it didn't smash itself to bits.

The article implies it's lifted straight from one of their petrol cars. I suspect this means 3 of the the gears will essentially be pointless.

[XitUp]

Would it not make sense to have 5 close ratios so you can keep it in that 5500-8000rpm bit?

You could lift the gearbox but change the ratios without it costing a bk.

For push bikes, that's pretty much what you get.

However, not only are they, to my mind, the most suitable, but they are conveniently VERY universal.
Ie, for a front hub motor, you can pretty much use exactly the same fitting in all case. You might want a different size wheel on top, but the main bit is the same (yes, for decent mountain bikes you get bigger spindles etc, but I wouldn't want a heavy hub motor on one). Few more difference for the rear, but not a massive number.

Motorbikes and cars tend to use very different setups.
Though, I can see some possibilities for making a universal front hub motor for small motorbikes; but it'd require a lot more engineering/bodgery still.
My ideal would still be for kits to be released for cars to make them hybrid, driving the other set of wheels.
Be nice to have that for my iveco 7.5t motorhome - so I get 4wd (after a long wet weekend parked in a field etc, can be quite useful to get out!), cheap running at town speeds and a MASSIVE leisure battery to use!
