Some time ago I left a review for the v3 footpad which had a sensor that was hard to activate. Over time its sensitivity deteriorated even further so I ended up switching "Disable moving faults" ON otherwise the board wasn't safe to ride.
Now I got this new footpad v4 which is amazing (so far)! :) I can wear any shoes with any soles and it activates perfectly and precisely. I'm very happy except for one thing. The footpad comes with a soft neoprene underlayer below the griptape. If you want to change the griptape - you're screwed. That underlayer is impossible to remove. I spent about an hour with a heat gun and was able to clean up the sensor relatively well but still got a bunch of residue left. Theoretically you can keep the underlayer if you just want to replace the griptape, but I use marine flooring material which is already soft, so I wanted a clean sensor. The v4 is definitely a great improvement but that underlayer is kinda weird. Not sure what it's for. Hope someone from Fungineers can explain.
used this for my custom build. Works great so far.
Suggestion: make a cable path for control boxes with the plug on the left! I could dremel it but would be nice if it could be routed either way.
Good
I have to mention that I am a very light rider at only 50Kg, but with the FM sensors I never had any problem activating them.
I've ordered a second one mid August 2025 because they've said that it has been improved, but I did not feel much improvements, I think it is actually worse than the original one I got in April 2025 which started to have bubbles and activation was no longer reliable. Now with the new one in the past 3 months it's been a struggle. I have to place my front foot in a very exact position to be able to mount and if I drop down from a curb, most of the time it is enough to move my foot away from that spot and it just deactivates.
I've let friends of mine ride the funwheel and it seems to work quite well for them as they are heavier than me, but at my weight it is barely usable in a reliable way. I can't trust it and I am expecting it to deactivate at any time I hit a small bump in the road. Currently I am using the "treat both sensors as one" setting to make it usable.
I *LOVE* all Fungineers products. Stompies will be the only exception. I got two pairs, all came with bubbles and really hard to activate. I'm about 90kg/200lbs and I can't even imagine how the lighter dudes are riding on those. BUT at the end of the day they work. I hope the sensor can be improved, and maybe some better QC.
