Speed sensor magnets Dyname 4.0

[sparrow]

The Dyname 4 uses three magnets on the rear wheel speed sensor. If a rider lost one magnet, wouldn’t that take the speed limit up 33.333% from the 20mph Class 1 limit?

I don't think the magnets work this way. You'll just get an error.

I think it’s precisely what devices like the following link do: PLANET3 - mechanical e-bike derestriction device

Well, knock out a few magnets and let us know what error code you get.

1 of the 3 magnets appears to be mounted opposite (pole-wise.)

Blargh, tricky bastards!

I'm servicing the rear wheel of the Altitude Powerplay 2023.
In the meantime, I want to use a spear wheel but I have to buy the speed magnets.
I would like to buy 3 of these:

Which version ( A/B/C), is the right one?
Thank you

I believe the theory of operation is it would need to read +-+-+-+ etc if you removed one it would need to be a +. However since they are positioned in 1/3rd around the hub you would get a "skip" +- pause+- pause+-Pause and probably an error.

The planet 3 has 6 magnets on the 4.0 RM device and a planetary drive so the sensor still will read +-+-+- just slower rotation than what it would be reading from the OEM hub mount 3 magnet device.

For a 2023 just buy the RM 3 magnet sensor vs 3 of those devices listed. They make two versions one for power spline and one for 6 bolt. First thing I did was swap wheels to run my Hope Pro 4 6 bolt so I had to order the 6 bolt magnet.
