If you care about what your locking, this lock is for you!
After MUCH online research, I selected the Kryptonite brand locks and then specifically the “New York” lock for a college family member’s electric scooter. I would have bought the “Fahgettaboutit” lock from Kryptonite with its 10/10 rating but it was not long enough for our application. But the “New York” is a 9/10 and specifically says it is strong enough for metropolitan areas and college campuses. Once on campus, our family member said her lock was the toughest of any she saw amongst all the locked bikes and scooters, meaning that the thieves won’t be going after her scooter first! Very impressed with both the company and the lock. Highly recommended. And we purchased this ourselves, and this is a voluntary review.

5.0 out of 5 stars ¡Chulada!
Reviewed in Mexico on November 26, 2023
Chulada de candado. Lo compré más que nada por el soporte ya que tengo una cadena New York pero pesa 7kg y está de la fregada andarla cargando. Normalmente me la colgaba como cinturón en la cadera pero aún así se sentía el peso mal plan.

Con este candado que igual está casi al tope de gama 9/10 será más cómodo salir a rodar y dejar la bike estacionada sin andar cargando nada por traer su propio soporte.

Anteriormente había pedido un kriptonite fahgettaboudit que igual está súper PRO. Pero para bikes de MTB no alcanza a asegurar llanta y cuadro, además que no trae montura para colgarlo en algún soporte y toca traerlo cargando en la mochila.

La cadena la usaré mejor para asegurar la moto. Pero reitero, este candado en cuestión de seguridad y comodidad excedió mis espectativas.

Así mismo vi comentarios que decían que instalar el soporte era muy complicado. Creo que les falta compresión lectora o sentido común. ESTÁ SÚPER FÁCIL.

Compra muy recomendada!!
