What is the lightest folding bike? One of the main things you might look at when picking a folding bike is its weight. In many instances, weight is a larger factor in the decision making process than it is when deciding upon a standard bike, as many folding bikes have the added benefit of being compact enough to carry around in one hand. As such, a manageable weight is a big plus. All of that said, we frequently encounter the following question: "What is the lightest folding bike?" By and large, every folding bike that we carry is engineered to be a light folding bike. If folding bike manufacturers did not make the effort to produce a light folding bicycle (or a compact folding bicycle, for that matter) it would be completely illogical. With a variety of options out there, within the large group of already light folding bikes there are a few models that can claim the title of the lightest folding bike.
