Late, I know... but maybe still helpful for others dealing with this and many other custom tamper-resistant schemes.
Especially around Christmas you may have seen on TV, the "Gator Grip" universal socket - a 3/8" drive deep socket featuring spring-loaded cylindrical pins that can form around the shape of conventional hex shapes, and unusual shapes, wingnuts, worn and deformed fasteners, etc.
Among the many offerings (and manufacturers) I've seen at Amazon, there are even heavier-duty versions made with closer-fitting hexagonal pins. But the original can be found even at Walmart.
With custom fastener designs on other e-vehicles, I've gotten lucky with the 5-sided utility socket, and the 7- and 11-splined sockets (made for locking auto rims), as appropriate.
Have also found 5-lobe security Torx bit sets at Amazon - didn't even know these were "a thing" until encountering them on one e-bike.
