Quill Stem adapter for Bike Taxi tow rope.
The Bike Taxi Adapter is an accessory specially designed to enable the Bike Taxi tow rope to be used on a bike fitted with a quill stem or any other type of smooth stem with no exposed bolts. 
It can be fitted quickly and easily to the handlebars of the bike to be towed, without the need for tools. Once in place, the Bike Taxi loop attaches to the adapter, allowing the rider of the towed bike to break the connection at any time. The adapter remains in place on the handlebars, while the buckle retracts automatically and safely.
