Tui ER4 Road Bike - Lightweight Titanium road bike

The Tui ER4 is a lightweight titanium endurance road bike with Shimano Ultegra Di2 2x12 speed electronic shifting. Available in sizes from XXS to Large the This bike is fully designed for to be proportional for riders down to 4'8". 

Tui Titanium Bikes was born from our goal to make sure that everyone can get a great bike that truly fits their unique body and riding style. At Zinn Cycles, we have been building custom bikes for short people including small women and men for over 40 years. We understand that a custom bike is not something that everyone can afford, so we have founded a new brand of non-custom titanium bikes for short people.

Major bike brands tend to focus their efforts to make bikes for the average sized person, since that demographic is going to offer the largest number of potential customers. That range is from about 5’7″ to 6’2″. The further you are outside of that range, the fewer options there are for you. That is where small companies like us can develop great bikes and components to help fit riders who can’t simply walk into a bike shop and find a perfect fitting bike.

When a small rider gets on a Tui titanium road bike sized to them, they immediately express amazement at how comfortable and natural their body feels pedaling it and how effortlessly and intuitively it handles, giving them a feeling of great confidence when cornering. This is no accident; it is the result of my careful and studied understanding of what the human body in general and a small body in particular requires to be properly supported on a bike for optimal pedaling efficiency, comfort, and control. All of my years of experience help me to truly understand what it takes to build bikes for short people.
