I flew last night (...) and I brought my bike. I'm gonna show you how I easily and quickly fly with my bike—and most importantly, how I just check this as luggage because I don't get charged a bike fee.

This model has one of the most ingenious folding mechanisms on the market.

Having a folding bike in the caravan increases mobility.
[The BYB] is a 20-inch folder that aims to bring the ride quality of your regular bike to one that folds small enough to fit comfortably under your desk.
I like bike designs that can be altered to fit a variety of body shapes and sizes and the BYB is just that. Being in the riding position that you want means you are half way to a comfortable and efficient ride before you even pedal.

The Tern BYB S11 is a great addition to the choice of folders out there, and a genuinely novel addition to the annals of folding bike design.
The BYB’s larger wheels give it a smooth, uncompromised ride and better stability than smaller-diameter wheels.
