No, there is a CX gen 4 non-smart and a CX gen 4 smart. The smart motor has a 4-digit product code like BDU37xx. The main issue is how the speed sensor is mounted onto the frame. You need a magnet mount that fits that position.
Do you have a photo of your magnet on your bike?
If you have a Bosch smart system motor with a slim speed sensor, it’s the right magnet. If you have a different Bosch motor and/or different speed sensor, you’ll need a different magnet.
You will have to make sure that the magnet fits your bike’s speed sensor/motor combination.
Those „rotor magnets“ you linked to are for two very different motors and speed sensors and will not work on both of those.
The differences to watch out for are magnet position (how far from center of...
Nearly all of them. Mainly defined by the price of the bike and the target customer group.
As an example you can find Cube hardtail eMTBs (Reaction Hybrid) from ‘23 that come with Shimano BR-MT200 brakes and 180 mm SM-RT26 rotors front and back. Brakes don’t get much cheaper.
You should read up on what actually happens during the tempering process. Nobody wants the same hardness in the core of a brake disk as on the outside.
Because only the rotor surface is tempered. The further the disk is worn the softer the material.
When the manufacturer laser etches a wear limit onto the rotor and not the calliper I tend to believe there is a reason for this and I feel it’s prudent to observe that limit.
The good thing is...
My first comment has never been my main concern. It was an answer to your comment about the calliper defining possible minimum rotor thickness.
By my reckoning the thicker rotors are based on a different rotor design not weaker material.
My main concern is not popping the pistons out, but having a catastrophic failure of the rotor worn to thin under heavy breaking. For me it’s not worth the small saving.
First time I read that. Do you have a source?
Also, if you put a significantly thicker rotor into your calliper, you will have to remove oil from the system or risk damage to it. This in turn will limit the usable thickness.
Shimano rotors are 1.95 mm thick when new and have a 1.5 mm wear limit.
Magura rotors are 2.2 mm when new and have a 1.8 mm wear limit.
No big difference.
I was always wondering why nobody came up with an IQ app for Garmin to record the data from Bosch motors. This makes me believe that Bosch have done a good job to obscure/encrypt the data or that it is only transmitted over the CAN bus.
For the time being you need an Apple watch to provide the...
If you only want to load data from your rides to Garmin Connect, then that is possible. I do that with all of my rides on a regular basis.
You will need to track your activity with the Bosch Flow app on your smartphone. Once configured correctly tracking will start automatically as soon as you...
Bosch eBike is a closed system, very similar to Apple.
Bosch interacts only with Bosch soft- and hardware. This is a known fact and I can’t see a change to that policy coming any time soon.
A few years ago I bought a pair of Adidas Evil Eye Pro glasses with photochromic (nearly clear to very dark grey) main lenses and a clip-in for prescription lenses. I had the clip-in fitted with varifocals and have been wearing this set for more than 10k km now. The photochromic lens is very...
A1: The light port will shut down when the load exceeds 18W.
A2: Below is a picture of the non-smart motor. The plugs on the smart system are in the same location, but they are round instead of rectangular. On most bikes you only need to remove the plastic motor cover from the non-drive side to...
