    The CVT element is interesting, I’d like to try one to see how it feels. Can’t see it in the exploded diagram, are they meant to look like two cones?

    How long until they do a CVT mountain bike.

    I got the email from decathlon on this too.

    super intrigued with this, first eBike I’ve heard of with a cvt setup & combined motor and gears. It almost seems as close as I’ve seen to the perfect ecommuter bike.

    Looks good. They could have gone belt drive which would have been nice.

    I’d love a go.

    Bike looks really interesting but that new Decathlon website is shit, truly awful browsing on an ipad

    Lots of interesting features but I don’t like the packaging. It’s like they went “those cheap bikes over there aren’t selling well, lets slap this really cool concept on them”.

    You’re thinking of the old ‘laggy band’ design employed by DAF in the ’70s and widely used in scooters/mopeds. Too lossy for a pedal cycle. The exploded diagram shows two sets of motor windings, so I’m going to make an educated guess that it uses differential motor speeds applied at different points in the gear-train to give an effective variable gain ratio.

    There are two motors and two drive belts. I wonder if it’s like the Toyota hybrid design where they have two motor/generators, and they can vary the power going to and coming from each to create variable gear ratios? Is that what you meant?  However I think the existence of a freewheel might scupper that idea.

    Hamsters. I’m going with hamsters. Two of them, brothers. One big, one small.

    The usage and care instructions are interesting, apparently you’re not meant to tumble-dry or iron it.

    But it is good to see that on the spec sheet for Connected it says Connected. No idea what that means but at least it is connected???

    Most of the CVT cars I’ve driven (all maybe) have been pretty jerky. Not too much of issue in a hire car, but I’m not sure I’d want that at the traffic lights on my commute.

    Is this a new thing or have cvt bikes been around for a while?

    NuiVinci 360 has been out for 17 years or so? Works very differently to the Decathkoin though I think.

    CVT is a concept, not a specific device. There are loads of ways of doing it – this will have nothing to do with cars you may have driven.
