But even so I'm betting very soon no maker will go the design choice to have a spoke magnet. The magnet in disc is more secure, looks neater, and also looks neater from the point of view of the sensor which becomes invisible, and aligned with the brake rotor the sensor is also in a location far less vulnerable to damage. However, the frame did have to be designed with that in mind. The bike I've ordered is an old frame probably designed before magnets in brake rotor came to the fore, so perhaps that's the main reason it'll be coming with spoke magnet.
Are spoke magnets a no no.

The rental bikes we hire in les gets area are cube and given the terrain we have been riding in there the last two years never had a n issue with the spoke magnets. But from atheistic point of view I would prefer the integrated route, hopefully the 2021 bikes will address this.
Fair enough. Pardon my poor choice of expression... I'm not normally that aggressive when it comes to criticisms coming from editorials regarding bicycles.
I have to admit that my reaction has more to do with the pandemic at large, lockdown isolation, collapsing businesses, lost livelihoods, death tolls... it's overwhelming and eating me up underneath. In the midst of such a global catastrophe, a magazine article taking exception to a magnet spoke (I don't really mind where it's mounted) was just a bit much for me to handle. I realise I've taken it out of context and shouldn't have juxtaposed it in the prevailing madness and uncertainty of our times. My spurn crept up on me out of the blue. Appreciate that you called it... made me reflect and sort out an emotional reset.
Yes, I think, taking into account the current situation, that reviewer should have followed Jacinda's advice to "be kind" to that bike and simply wrote "this bike is a lovely bike, faultless in every way". lol
Have to say I never imagined my comments might induce an emotional reset beneficial to mental health and well-being, but thanks for letting me know - always happy to help! And I definitely think I should be awarded a shed load of forum points for that!
Anyways, your in New Zealand, just about the world's least affected country, so do as Bobby: "Don't Worry, Be Happy"
I've only had 2 occasions where a spoke magnet has caused an issue. So not too much of a problem there.
Nothing really that wrong with spoke magnets.
It's just not the most well thought out solution. For a premium bike of say £5K+ I'd expect the designers to have looked at every detail, including how to neaten up the spoke magnet and integrate it into the rear rotor.
Same for cables, screen placement and integration at the front. To me it tells me how much thought has gone into the entire package.
Rewind to 2007. Both of these made phone calls ?

. Even though Rob's recently been on this thread he never awarded me any extra for sorting you out so I'm still only on 18 points . Seems all he cares about is electric bike chit chat and not people's mental health. Perhaps you could have a word with him?

For my YT, unless they change the 6 bolt configuration, I'll have options of any discs I want. I do see your point though, change for the sake of change is never a good thing. Spoke magnets have advantages in flexibility and I have never lost one.

Belts and braces. Buy a spare and put it on the front wheel and forget about it until you need it . Also, when you change your back wheel, don’t ride up the road wondering why your bike is not working properly, and then remembering that you haven’t swapped the magnet as well. Like I did?

Yes... the magnet in itself (be it like a monkey awkwardly resting halfway up a coconut tree) doesn't really pose that big an issue. The real problem associated with it however - is the location (and therefore vulnerability) of the speed sensor, because it usually has to stick further in from the narrow portion of the swingarm to be close to the magnet. What this means is that every time we remove our rear wheels, the rim and/or tyre could inadvertently bump the sensor. I do keep an eye out for it, but I still bump it sometimes - while handling the chain against the cassette and because eMTB tyres are pretty wide.
Having the magnet on the disc brake rotor is obviously a more elegant engineering approach. But that could hinder users from swapping to preferred aftermarket rotors that are not designed to accept magnets (until the industry catches up). Also, the magnet mass may also act as a heat-sink which could cool one rotor spoke more so than the rest... which could cause the rotor to warp in situations where these rather thin discs reach extreme ’black-n-blue’ hot. Magnets don't go well together with heat either because they could demagnetise over time. The bike industry would also have to agree on a standardised location for these 'rotor magnets' for universal interchangeability, and manufacturers aren't always known to be cooperative in that respect. We might get there in the end (one would hope), but I can understand why some brands choose to stick with the 'spoke magnet' for now.
However as you and the rest of us have surmised, having a spoke magnet config in the meantime is not worth losing sleep over.

Is there really a "spoke magnet issue"? Or did you just read a few random posts about some magnets falling and all of a sudden you're calling it an issue?
You're overthinking it. It's not an "issue."
Buy your e-MTB already and enjoy it... then buy a spare magnet for $4 if you really fear losing one. Or use some threadlock.

I guess I've been referring to a certain German emtb magazine which has given extensive reviews for 2020 bike. The bike I'm hoping to buy wins the best buy under 5k. They are just very critical of the spoke magnet design with it being exposed (they lost one on ride review) to going missing. Now if you spend 5k on a bike you kind of want to know how likely this is to happen. It's good to hear some of the replies on here of emtb riders not put off spending big bucks due to the criticised design.
I Repent! I repent and confess my non-believing sins!! For lo and behold a miracle: more forum points - big beautiful forum points - than you could shake a crook at have miraculously resurrected themselves. There is one true god after all and he cares for all his pedal-assisted flock. I only hope the Lord Rob doesn't so readily taketh with the one hand what he so munificently giveth with the otherI've none extra to enjoy

Hmm....maybe if I visit the alter to subscribe I can remain his chosen son The points etc area automatically given when you reach certain milestone, e.g 50 likes, 100 posts etc etc. You can see in your profile the points you have, I have never paid much attention but from time to time I see the tags under my name change.

Unless the front one falls off first...........you didn’t think about that did you Bill

Damn it, Mark. Trust you to find a flaw in my cunning plan. Oh well, back to the drawing board.....
Up there for thinking ....... down there for dancing or peddling ?
I think Trek (Rail) have it in the frame and it looks very neat. They also have a hinged charging point cover so the rubber bung (Cube) doesn’t keep falling out.
Won’t affect performance and just design features but less to worry about!
