The Metric is a small-wheeled utility bike, inspired by our visits to Kyoto. ‘Mini-velo’ adult bikes are a huge trend in Japan, where they are stored in tiny apartments and used to zip around the city back alleys on errands. It doesn’t fold, which means the steel frame is elegantly slim, light and more rigid than a folder. Fitted with slim racing tyres and 7-speed gearing that can propel you up hills, it's surprisingly sporty, and also comes with a handy small front porteur rack and hammered alloy mudguards.

You will need a multi-tool or hex key set, 10mm spanner, 15mm wrench, scissors, pliers, a screwdriver and a pump.
Some things to note:
If you assemble your own bike, it’s very important that you do it correctly. If you have doubts, pay your local bike mechanic to check over your handiwork or assemble it for you.
In the first few weeks of use, you can expect your bike to ‘bed-in’. You must check everything is tight before each ride. Cables will stretch so your gears and brakes will need adjustment.
Finding the correct size bike starts with measuring the legs. Take a measuring tape, place it on the floor inside the leg and measure upwards. Now check the chart below.
