Hi, Great video mate. If I put the magnet further from the centre of the wheel (as it is on the rear brake disc) and the sensor too, will it make a difference on the speed ? I think not .. ?
Otherwise I may try this pedal strategy

[burty]

Good video. Are you still selling the magnets?

[hp]

How do I get one of these magnets. I've watched dozens of vids on YouTube and not one tells you what size and strength of magnet to buy. There are loads of options.

[alexscott]

Does the warranty go if you do that mod

[punisher]

this will give a 504 error for sure, after only 3 times it will be in permanent limp mode and needs reset at dealer.

[bruzilla]

What happens if im getting this error but my magnet in integrated into the back hub or brakes???
