Rear airless tyre (Tannus) + front Brompton Kevlar tyre? (Brompton)

Thinking of installing a purple Tannus rear tyre for my wife while using B.Kevlar or S.Kojak for the front.

- Looks cool? Or just plain weird, I have no idea.
- Speed is definitely not a factor for her, so I think the added rolling resistance would not be a big deal
- It takes care of one of the worse-case scenarios where the rear tyre blows and needs to be removed or such - the front tyre is simply easier to remove and fix. (I think)

Any technical reasons why this shouldn't ir can't be done? Thanks.

Not my experience, but there was discussion in the above link (if you read Chinese).
One guy resold this tyre in half price right after 10 KM test ride. The drag was unbearable.
Maybe you should install it on your B instead, to match the speed with your wife.

Also, I was told I need to buy extra parts to convert my bike from a M6R > M6L. So if I had to change the M6L > M6E, would I need more parts?

I thought removing the rack/fenders would have been sufficient. Sheesh

Surprisingly my terrible Chinese could still make out 70% of it. It seems he's using a set of Tannus tyres, which I know has a big difference in rolling resistance even compared to Marathons.

My main concern is whether the Tannus could be used in conjunction with a regular pneumatic tyre - or will it be virtually unrideable for any reason? I know front Kojaks are used with B.Kevlars and Marathons.

Correct me if I'm wrong, but I think

M6R > M6L, you need the single eazywheel attached on the fender.
M6L > M6E, fender out. eazywheels extender won't work.

Do try the airless but colourful tyre, waiting for your review!

Well I did manage to talk to the Brompton shop, and they told me I needed to buy an addon to keep the
cables from rubbing against the front wheel for M6- to M6E.

Hmm I don't remember having a blog or a reality show, so I guess now you're just bordering on stalker-ish behaviour o.O;

I wouldn't know where to buy one, though I guess I could pay a mechanic to do it.

Brompton Cable Fender Disc QCFDISC - 4.75

You can buy one there, or make similar one.
