How fast can one speed go?

To answer the question directly:

yes, although they are one speed rides,

they are still very fast.

Our Moose however, in terms of pure performance, do not compare to pro cyclist bicycles that weight less than newborns and that cost thousands of dollars. For urban riders, this represents a twofold advanrage: for one, our Moose, evidently heavier than Tour de France's bikes, are much tougher and resist well to the punishment of Canada's roads. Second, you just do not want to lock up a bike that cost you two our three times your montly appartment rent; you never know what can happen. Although being very high-quality rides, our Moose are affordable, which makes them less susceptible to robbery.
