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.
Metric is a one-size unisex machine that can be swapped between colleagues and family members. Riding this bike will fill you with joy and make you look very cool indeed.
Top tip: the slim racing tyres can be replaced for wider ones if you are regularly riding on rougher roads and tracks. The bike uses high-pressure (100 PSI) tyres and needs pumping up every few weeks.
These are estimated delivery times and may be affected occasionally by factors outside our control. If you have a deadline - a birthday for example - make sure you order well in advance to avoid stress or disappointment.

Assembling your bike is empowering. It’s a great way to understand how it works! Please click here to view our step by step guide to assembly. View our assembly video here.
The bike arrives in a box. The handlebars, front wheel, front mudguard and pedals must be attached.
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.
