First of all, fuck Future Motion on the C&D for REWheel. Also why haven't they still haven't patched the security vulnerability of hardcoded AES key in their devices? REWheel was specifically architected so that it did not share any IP, and they came in and bullied Nish under an archaic clause in the DMCA that's being hotly contested in R2R. The VESC implementation was Whitebox reverse engineered and none of the coders (Mitch, Dado, Nico) ever even looked at any FM binary. All REWheel was trying to do was let users repair their BMS's and re level their boards for aftermarket rails as well as provide safety features so that boards didn't drop users.
Besides this recall, here are all the other issues with their boards:
1) BMS discharge protection shutting off board instead of pushback/buzzer.
2) Wires breaking in cable harness leading to BMS communication drop shutting off board during mid ride (my friends have broken bones on the XR because of this).
3) Pint X Balance cable pinching
4) GT motor connector coming loose during midride leading to board cut off.
5) Lack of locktite in controller box screws and nuts (common for power button nut to come loose and short controller in Pint)
6) Lack of proper waterproofing in controller and battery box (should put silicone sealant around connector ports internally and externally)
7) Water getting into Pint motor connector causing short (should put dielectric grease on all connectors)
8) Underspeced charging connector on Pint PCB for hypercharger leading to arcing and damage.
9) Unknown reproducible GT shutoff over certain bridges on later hardware revisions. My theory is that you swapped out IMU because of chip shortage and didn't validate high pass filters properly. Either that or GT motor connector looseness issue. I can go ride one of my friends GT and make it shutoff right now if I wanted to by riding over certain bridges! It's insane!
10) Underspeced mosfets on controller leading to lack of torque and recovery in nosedive situations. My VESC Pint beats the GT on hill climbs.
11) GT axel weakness leading to breakage.
12) Powder coating on GT rails leading to overheating
13) Lack of proper coolant (like statoraid) in GT Hypercore hub leading to overheating.
14) Reverse polarity on XT-60 connections (this is just evil)
The above design flaws have lead to multiple injuries and broken bones in Future Motion devices that I have mitigated in all of my VESC boards I have built for myself and the people I love and don't want to see get hurt.
OneWheels are great devices. I myself have close to 10K miles on them. I have felt infinitely safer after I started converting my own to VESC boards, removing the discharge path on the BMS (so it couldn't power off the board unexpectedly) and disabling moving faults (so it couldn't drop the user due to a failed footpad). This has been achieved by swapping out both the BMS and ESC to open source, aftermarket solutions.
