wiuld like to pick up a good bike lock for my new cube ebike. At the end of the day I’ve decided to go with kryptonite. Looking at the New York or forgetaboutit. Can any tell me if the forgetaboutit is big enough to go through rear wheel seat post and then around sign post like a stop sign. I know the New York would work but if I can get away with a smaller lock will be harder to get any mechanism in it to break it

cheers
