The internal hub is great
By Colbert T. in San Francisco, CA on 05/19/12
I do not claim to be a spandex-wearing bike aficionado or a snob, so I was quite pleased to come into PUBLIC Bikes when I was looking to get a decent, sturdy urban bike. The customer service at PUBLIC has always been wonderful with their staff being attentive to all my needs whether it was answering questions about riding in the city to maintaining my bike. The people are friendly and this is a great business that helps to encourage people in the community to ride bikes.

As for the bike, I gotta say the internal hub is great on my D8 and I love riding my Chartreuse bike around town. It's a functional, stylish bike that does the job. I love the compliments that I get from people as I ride this bike. It goes to show that the PUBLIC Bikes have a lot cool retro styling that makes people's heads turn. I've had my bike for almost a year and it's been solid and dependable. I highly recommend PUBLIC Bikes for people who are newbies to a seasoned veteran who wants a great bike to ride around in the city.
I've gotten tons of complements

Beautiful, easy, functional bicycle. I've gotten tons of complements, including a guy who pulled his bike over to ask me where i got mine. Staff couldn't have possibly been more helpful.

With refinements in style and performance, we can confidently say the new PUBLIC D8i is one of the best commuter bikes available.

Beginning with the frame, we built the PUBLIC D8i around a lightweight 100% chromoly tube set, ensuring a strong and durable bike with a buttery smooth ride. Next, we upgraded the drivetrain to Shimano's premium 8 speed offering; the extra smooth Shimano Alfine 8 speed internally geared hub, in an elegant polished silver finish. We added new high-polish silver alloy fenders, to complement new durable black commuter tires with reflective sidewall details. Additional upgrades include a more elegant and adjustable one-piece forged seat post and a streamlined PUBLIC commuter saddle. Finally, the cockpit sports our new alloy PUBLIC swept-back city handlebars and a negative rise road bike stem for sportier city riding.

Built to endure tough city commuter bike conditions, the PUBLIC D8i comes equipped with strong double-wall wheelset and matching black deep V-style rims. Strong alloy dual pivot brakes ensure fast and safe stopping rain or shine. High quality polished and anodized fenders protect you from road grit and make sure you arrive looking sharp, and the integrated alloy chainguard keeps your clothes clean and dry. You won't have to roll up your pants leg to ride in style for the office or the evening.

The new silver and jet-black PUBLIC D8i is every bit a PUBLIC, and quite possibly our best commuter bike ever.
