PUBLIC Bikes - Metro and Citizen

PUBLIC Metro
Available on November 18, 2010

PUBLIC, known for steel mixte bikes with 8-speed internal hubs for $890 (or 3 speeds for $750), plus shipping, has now come out with a pair of recession-priced city bikes. They have almost all the features of their pricier siblings, but save money with regular fenders and rims (instead of stylish powder-coating to match the frame), cheaper tires and tubes, a unicrown fork, and a 7-speed rear derailer instead of internal gearing. However, they includes just about everything else you would need, except for a rack or basket (matching ones are sold separately).

Here's what PUBLIC says about the Metro and Citizen:

  • Comfortable: Steel tubing and accurate frame geometry make for a softer ride than with other materials. Seats are designed for normal clothing.
  • Ergonomic: Upright handlebars keep you looking forward, not down. They're also kinder to your back. [The Metro is particularly upright, though the seat tube angle is steeper than on a "dutch" bike - BFTROU]
  • Practical: Kickstands so you don't have to prop your bike up against a lamppost. And chain guards to keep grease off your fresh, clean clothes.
  • Modern: The Shimano 7-speed rear derailleur and Revo twist shifter brings state-of-the-art technology to the shifting system. Changing gears is done with a simple twist of the wrist.
  • Safe Braking: Powerful alloy brakes combine with lightweight alloy rims with machined brake surfaces for quick, safe and controlled stops. [Caliper brakes limit potential tire and fender width, and are less powerful than linear-pull cantilevers, but should be fine for most, and look nice - BFTROU]
  • City Smart: 35 MM tires are wide enough to handle curbs and potholes but narrow enough for speed.
  • Feet Friendly: Pedals designed wide enough to ride with boots, pumps, flip-flops, or anything in between.
  • Durable: The Chromoly steel frame will last a lifetime, if cared for properly, and is guaranteed for life. [Don't leave it out in the rain to rust - BFTROU]
  • Serviceabliity: Durable seven-speed Shimano derailleur can be maintained by any bike shop.
The loop-frame Metro is paired with a diamond-framed bike, called the Citizen, which also sports a 7-speed rear cassette and derailer. Besides the slightly different frame shape and geometry, the two bikes are very similar. And both are relatively affordable, at $495 (plus shipping). And until these bike are available, the previously reviewed Mixte and diamond-frame models are available with a $50 discount (free shipping), until Nov 16th.

I emailed PUBLIC Bikes to ask about the geometry of the new frames, and this is the table they sent me:

Both the Mixte and the Metro have  standard Amercian hybrid seat tube and head tube angles, moderately long chainstays, a good bottom bracket drop (for a reasonable seat heights), and sensible top tube length and wheelbase. The Metro's loop frame provides a higher headtube, which will make it easier to set the handlebars higher for a more upright seating position, compared to the slightly lean-forward position encouraged by the Mixte's frame. Fortunately, the threaded quill stem gives you plenty of options for changing handlebar position to suit.

Hopefully PUBLIC will consider supplying the Metro loop frame with a 3-speed internal gear hub option, next year. It should only be a few dollars more than the 7-speed derailer, and would add to the bikes "Dutch-ness", and would also compete more directly with the Linus Dutchi.

Those are some handsome bikes. But I can't help but think they'd be even nicer with the internal hub. They just look... wrong somehow with the derailleur.

Looking at the new loop frames and the mixtes, 3 things come to mind:

1. They should have put the 1x7 derailleur on the mixte and the IGH on the loop frame, as is more traditional. The way they chose to do it instead, both bikes look a little off - particularly the loop.

2. The 3-speed mixte models have unicrown forks as well, at least the ones I have seen in a local store

3. A 74.5 degree seat tube angle for an upright loop frame bike is surprising.

I am curious to read some owner reviews of these.

The same length chainstay on all three sizes is a mistake. It's a cost-cutting mistake, but does not allow for consistent ride quality between sizes.

1. It's more traditional but this is a Left Coast-based company.
