Hi

My name is Emmanuel Eng and I need your help to move my newest bicycle frame, the Sutro, into production. I developed the Sutro in collaboration with Mission Bicycle Company to serve as the most practical and elegant geared city bike available.

The Bike

The Sutro was designed by and for city cyclists to be ridden everyday and everywhere. We took the simplicity of a single speed bike and added the versatility of a Shimano multi-geared internal hub. Then to achieve a clean aesthetic we routed the brake and shifter cables through the frame.

Sutro with 8-speed Shimano Alfine Hub

8-Speed Internal Hub

Our first bike, the Valencia, was designed around the simplicity and dependability of single speed riding. It was our answer to the clunky, heavy and unreliable bikes marketed for the city. However, we knew one gear wasn't the solution for every rider. 

So we searched for an alternative that offered the flexibility of a fully geared bike while retaining the ease of riding and near zero maintenance we'd already developed. We fell in love with the mechanical wizardry of the Shimano internal multi-geared hubs and the potential they offered.

8-gears enclosed inside the rear hub

These hubs allow a simple setup while providing a huge gear range completely enclosed inside the rear wheel. Free of complicated and delicate external parts, they are resilient and practically maintenance free. No dropped chains. No crossed gears. No more derailleur adjustment.

A single bar mounted shifter simplifies the process

Internal Cable Routing

We've routed the cables for the shifter and the rear brake inside the tubing of the bike, creating a clean and elegant appearance. Just another way we've seamlessly married the form and function of this bicycle design.

Materials

We build this bike out of 4130 chromoly steel for its high strength, low weight and durability. Steel is the most resilient choice for city bikes as it takes the daily abuse of riding better than any other frame material. Meanwhile, at 24 pounds, it's light enough to hoist up a few flights of stairs.

Strong and lightweight steel

Design and Build

Using the Sutro as the canvas, each bicycle is custom designed by each rider, anywhere in the world, and built one at a time by Mission Bicycle Company. The experienced staff and curated components will help you turn this innovative frame into a bike specific to your needs. No experience necessary.

Choose from hundreds of frame colors

Our Story

Eman Eng: I’ve put the torch to dozens of different frame designs and I’ve ridden each one through the streets of San Francisco in pursuit of the perfect city bike. Each success was assimilated into the next design and after many years and many miles the Sutro was born.

Mission Bicycle Company: We began with a simple premise, give people the bicycle they want and they'll ride. Each bike is custom designed by each rider and then hand built right here in San Francisco.

Next Steps

With your support we are going to release the Sutro out into the world. If we meet our goal the frame will go into production and all backers will receive their rewards. If we don’t hit our funding target, no money changes hands. To reach our goal we are giving you the opportunity to be among the first riders of the Sutro and to do so with great incentives.

Complete Bicycle Backers Please Note: The complete bicycle reward at $1,234 includes customization of standard components and colors. Further customization and upgrades are welcomed and available, but not included.
