E-Bike Ready Tyres?

[awol]

Picked up a couple of Schwalbe Marathon tyres and put them on the other day. I've only just noticed this on them.
What could make tyres E-Bike ready I wonder?

Perhaps they're sub-standard compared to normal bicycle tyres, because they're limited to 16 mph. were as normal bicycles do up to around 60 mph.

Expensive !!!!!!!!

This is one of life's mysteries. More than a decade ago Chinese tyre company Maxxis supplied tyres for the Giant Lafree with "For electric bike" branded on the walls. They were very free rolling but punctured on first sight of something sharp. Recently Chinese company Kenda started supplying "electric bike tyres" for some Wisper models. Now it seems Schwalbe have joined in.

I've never been able to find out in what way they are different. The only possibility I can think of is that the wall construction is designed to have greater resistance to circumferential flexing under higher rotational energy inputs than that of a rider alone.

Looks like the '50' on the tyre in the OP's pic refers to 50kph, so the tyres are designed for naughty S-pedelecs.

From the Schwalbe website:

"E-Bike Ready. The new Marathon has been designed for use on all types of E-bikes. The following sizes bear the ECE75 mark, suitable for use on faster, up to 50 kph, E-bikes."

Thanks Rob, that's a first then. The previous ones were only on legal UK pedelecs. Mind you, I did used to exceed 50 kph (31mph) downhill on my Maxxis "electric" tyred Lafree, and they never blew up!

Hehe, this is a concern, as I have already clocked 35 mph on mine down a hill, and I am still getting used to the handling. Down a hill near me, I regularly saw 50 on my Dawes Galaxy. I hope the Schwalbe Energisers are ready for it!

It was a joke. I'm going to return to a normal bike, I go a fair bit faster on one of those than I ever could on a speed restricted e-bike.

Yes, I guessed that

To return to the original question, my guess is that they are simply a heavier version of a standard hybrid tyre, considering that many ebikes are a lot heavier than a normal bike. A bit like some car tyres are rated 'heavy duty'. My bike has a loading limit of (I think) 130 kg, and big chunky rims that would look a bit silly with a skinny road tyre on.
