Delayed from yesterday when I was mad busy, here's a little Triumph 20 shopper bike. These 20 inch wheeled bikes were made popular back in the day, and really they make a lot of sense. By having these smaller wheels you do reduce the potential top speed of the bike, but with that trade off you get much better acceleration from a stop and a reduction in the force needed to progress along at lower speeds. Ideal for city use then! It's why the folding bikes being made now by the likes of Brompton and Dahon with the smaller wheels make so much sense.
