Will my e-bike optimally secure and have decided based on the positive reviews and also present test reports for this Folding. Of course it has its weight, but with a 500 gram lock you can not nunmal reach optimal protection. There is wobble-free to attach with Velcro to the wheel. Laborious it is certainly, if one -of whatever reason must always- carry short time the wheel. Two elements would facilitate more connection possibilities, but would again affect the weight. Basically, it's attached to solid objects easily with not too widely, you must be able to draw near just close enough to the wheel. Everything has its price, I would buy myself again.
