Question about Vmax VX4 GT

Best with handcuff lock

a pity

I bought a handcuff lock from amazon with which you can lock it otherwise not just a switch-on pin

Sorry to hear that! I always lock my Vmax with a Kryptonite U-lock (not the small one!) if I don't have it in the cellar compartment. And always to something fixed like a bike stand, roofing pillar, etc. Unfortunately, it's not possible to lock it with just the bike, the opening in the bike is too small. In any case, activate and change the password on the display to make it more difficult for thieves...

Chain through the front wheel, lock on. Pin code. Nothing else that I would have discovered.

So locking in the sense of an eLock or something like a car key?
