In my world there is some bicycle event almost every day.

(from the SFBC)

Celebrate ‘Gas-Free Fridays’ with The San Francisco Bicycle Coalition
Grab your bike and a friend or co-worker and pedal by one of the SFBC’s energizer stations to fuel up on free coffee and snacks. The SFBC wants to encourage more people to substitute one short car trip with a bicycle trip on Fridays in October. It’s easier than you think, half of all driving trips in San Francisco are under two miles in length—a distance easily travelled by bicycle.

Fuel up station locations:
Oct. 2 | 8-10am Market at 12th
Oct. 9 | 8-10am Fell at Masonic
Oct. 16 | 8-10am Seventh at Folsom
Oct. 23 | 8-10am North Point at Polk
Oct. 30 | 8-10am Market at Sixth

A new class at MIT -- wishing I was there just to take this.

SP.712 D-Lab Cycle Ventures
D-Lab Cycle Ventures explores bicycle technology to provide human power for an increasing array of other purposes including water pumping, grain grinding and transport of loads in underserved communities with the aim to offer economic opportunity. The course provides a historical prespective on innovation in bicycle technology, reviews its engineering mechanisms and draws on the ubiquity of bikes to present them as innovative tools to foster socio-economic development. The course involves lectures and two types of projects. Early in the semester the whole class tackles on a single, joint, design and fabrication project. Later, students will form teams and take on design challenges from organizations that work with bicycle based technologies around the world. Optional January travel to partner communities. Enrollment limited.
