Guys: Quick release levers for thru-axle do exist. These are compatible with very specific bike frames and forks. For instance, you would easily (but at high cost) buy the MTB standard QR thru-axles (Boost: 15x110 mm front and 12x148 mm rear) or non-Boost ones: 15x100 mm front and 12x142 mm rear). However, such hubs are not very common for many e-bikes and using a regular hex wrench is the normal practice.
For instance, the front hub in my Vado SL is 12x110 mm, for which I could not find a QR thru-axle.
Has it occured to you that a QR thru-axle would make it easier for a thief to steal your wheels?
