We just installed a set of these on a customers bike. Can confirm the fantastic power and feel. Tons of lever adjustability finishes off one of the best brake systems in the industry.

Hi all! By now it is well known that Transition Bikes sells direct as well as through a dealer network. What you may not know is that you can help support that dealer network by having your bike shipped and built by a local dealer at no extra cost to you!

If you want a bike that we do not have or cannot get feel free to order it from Transition and make the shipping address our shop address. We will build it and tune it at no additional charge as soon as it arrives, PLUS you get the benefit of 5 years FREE adjustments and 10% off any accessories.

We try and keep our in stock inventory current at our website www.mjscyclery.com but call and confirm.

I’m exceptionally proud of San Diego native Gwen Gibson. I had the opportunity to watch her race in the SoCal High School Cycling League and her fantastic positive attitude was infectious. She has had a breakout year at the UCI Elite level and earned a Bronze at World Champs.

Keep it going Gwendalyn!

Need a better drink holder on your stroller? Check out the HandleStash! In stock at MJ's Cyclery.

So many people told us they needed a better cup holder for their stroller. Glad we could make it happen!


Have you been waiting on a Transition Sentinel Carbon? We have one that we just received and delivered to its new owner (who patiently waited over a year) and we have another Large GX on the way! We also have an alloy Spire NX in medium in the shop as well as alloy Sentinel completes, a Spire Carbon frame size XL in Huckleberry, and Patrol frames in Large and XL. Possibly the most exciting bike on the way is a Spur XO in size small. Come see us! These bikes won’t last long.

Our Story

MJ’s Cyclery was formed in 2013 by two friends who love to ride bikes. Knowing that there were a ton of shops out there whose focus was high end road and mountain, we wanted to try and make bikes make sense to the people who may not want to live the bike life but saw the utility of bikes in their day to day lives.

All of us at the shop are mountain bikers too, so we are very comfortable discussing getting dirty too.

MJ’s Cyclery focuses on the items someone might need to start riding their bicycle for utility. Bags, racks, lights, locks. We try to have a variety of these items here and love to look into new things that our customers tip us off to.

We also sell new bikes by Marin Bikes, Surly, Soma, Transition Bicycle Company, and Brooklyn Bicycle Company.
