Did you know that you can change the magnet for your bike computer? You can! And even with a magnet that is stronger and lasts better than the original cadence magnet that comes with your cycling computer as standard.
The solution: this small magnet
We want to teach you a lot about magnets, but we try to boil it down so that you can spend the time cycling instead of reading - and if it needs to go really fast, you'll find the magnet right here.
Above you can see the difference between the original cadence magnet (the one on the right "Garmin") and ours (the one on the left "Magnetz" (our Danish webshop name). The one from us is stronger. It doesn't have the grooves on the side that the original bike computer magnet has, but that only makes a difference if you have wet fingers - otherwise, they're both easy to screw on with the external thread. It is therefore easy to replace the magnet.
Should you lose or break the small clamping plate that comes with the original, there is also advice for that: you can either buy a new original plastic cover, or you can print it yourself with a 3D printer. You can find the 3D drawing and specifications on Thingiverse.com - search for bike magnet (or "cykelmagnet" which is the Danish term we found it under).
This is how to do it - DIY
The magnet must be assembled with a plastic clamping plate on a bicycle spoke on the rear wheel. The first photo shows the original set from Garmin:
The second photo (below) shows a combination of our Ø13 magnet and a 3D printed clamping plate - but it works just as well with an original clamping plate. This is just to show you that both solutions are possible:

You can also put a cadence magnet on the pedal arm. We recommend the 22x6 mm. rubber magnet for this, which is our bestseller for the pedal arm. Then you won't have to fasten strips around the bike - not because it doesn't work well, but the magnet is far more elegant as is, and it gives more energy and lasts longer (at a much lower price).
In addition, we have received feedback that common magnets for the pedal arm tend to get too hot in the summer heat, which causes periodic failures during a bike ride, but this is avoided with our rubber magnet. However, we must add that we have not tested this feedback ourselves, so this is based solely on customer testimonials.
ATTENTION! Most pedal arms are made of aluminum (which is non-magnetic). Therefore, the magnet is stuck to the pedal screw, which is usually made of magnetic metal. But if the pedal screw is also made of aluminium, you have to attach the magnet with glue or with strips.
This is what it looks like with the standard equipment for your cycling computer:
And this is how you can make it look with a strong rubber magnet, placed without strips:
