Bikes & Frames

Track / Fixie

Whether you're racing at the velodrome or just love the feel of urban simplicity, we have a fixed gear bike that will fit your needs.

Touring / Trekking / Randonneuring

Tour the country, trek off the beaten path, or participate in a randonee on a bike designed for adventure.

Commuter / Cruising / Town

Leave the car behind for a cleaner ride to work or the grocery store, and cruise in comfort and style while out for a night on the town.

Road / Hybrid

From rolling hills to the steepest of mountain ascents, feel the wind in your face in the saddle of a steel, aluminum or carbon road bike.

Cyclocross / CX

For the novice and the best of bunny-hoppers, mount one of these cross bikes for the love of the off-road course as much as the on!

Mountain / MTB

Conquer the singletrack as you clear rocks and maneuver drops on a steed that can withstand the abuse you're sure to put it through.

FAT Bikes

Fat bikes are going where no bicycle has gone before. Extra wide rims and obese tires allow for great traction in dirt, sand and even snow!

Kids Bikes

From learning balance and neighborhood fun to serious competition, we have bikes for every age, size and ambitious spirit.

Status	Description
Available	We've got it in-stock and ready to ship.
Special Order	It's not in our store but as long as one of our hundreds of suppliers has it in-stock, it'll be on its way to us within a day or two of your order.
Custom Build	These items must be built to your specifications by our professional mechanics, so they take a little more time to ship out.
Pick Up	Some manufacturers (particularly those of bicycles) prohibit online sales AND shipping in order to protect small shops like ours. In these cases, you may make your purchase online and pick up your order at our store in Sacramento.
Limited	These items are being cleared out at significant discounts and limited quantities are available. Once they're gone, they're gone for good!
Back Ordered	We're waiting on more to arrive from our supplier, but because we don't know exactly when that will be we can't accept orders at this time. Give us a call for the latest ETA.
*Like all things, our inventory system is not perfect. Occasionally an item will show in-stock when in fact it is not. If this occurs, we'll notify you right away. Rest assured that your credit card will not be charged until your order is fulfilled.
