Tern Link P7i and Swoop D7


Tern is a new folding bike company, which split from Dahon. They now offer a wide range of folding bike designs. Similar to Bike Friday and Brompton folding bikes, there are meant for people who want to travel with their bike, who need to keep a bike in small space, or who have a multi-modal commute which does not allow standard-sized bikes.
Tern Link P7i
The Link P7i, "The equipped one" as they say, comes with almost everything you could want. Dynamo hub and lights, a Shimano Nexus 7-speed internal gear hub, rear rack, fenders, and chainguard  (attached directly to the chain) are included. There is a bracket on the front of the frame to attach a bag or front basket, which does not affect the steering. It is available for $1200 at Clever Cycles and other shops.

Tern also sells the Swoop d7i for $1000. It also has a rear rack and optional dynamo lighting, with a 7-speed hub, and a standard chainguard.

Brompton

While not made in the USA, like the Bike Friday folding bikes, Brompton folding bikes are often touted as the bike with the most compact folded size and a very quick fold. This makes them a good option for people who need to combine a bike trip with trains or buses which do not allow full-sized bikes, or who want to fly with a bike when visiting another city. They fold down to a package that is a few inches larger than their 16 inch wheels.


The bikes and most of the special components are made in England, and there are many customization options, including all of the options we like here at Bikes for the Rest of Us: fenders, dynamo hub and lights, rear rack and a front bag or basket. Most are sold with a unique 6 speed drivetrain which combines a 3-speed internal gear hub with a tiny 2-speed derailleur.


There is no kickstand option, because the bike itself is designed stand up when folded, and there are small wheels on the rear carrier to allow it to be rolled around like a shopping cart when taken into a store. The front bags or basket attaches directly to the frame, above the small front wheel, instead of to the fork or stem as with most front baskets. This means a front load does not affect handling, and a surprising amount of cargo can be carried on one of these bikes.



Bromptons are also designed with surprisingly quick handling and a slightly leaned-forward position. This combined with small wheels, which accelerate quickly and light weight make it handle more like a road bike than a traditional city bike. The frame is meant to accomodate a range of riders, so taller people will have a more leaned-forward posture, and shorter riders are a little more upright. This can be partially counteracted by different handlebar options.
The most expensive options, including a titanium frame and fork, can cost over $3000 (above).
But the complete bike at the top of the page with 6 speeds, dynamo hub, lights, fender and the addition of a rack is under $2000. The most basic model is just over $1400.


For people in some cities, bike sharing systems, and access for full-size bikes on buses and trains, have made folding bikes less essential for multi-modal trips, but they can still be the perfect solution for some people, so it is no surprise that Clever Cycles in Portland has trouble keeping Bromptons in stock.

Bike Friday

Many have lamented the decline of American bike manufacturing, as most production frame builders have moved work to Taiwan or mainland China in the past 2 decades. Now most custom USA built frames will cost over $1000. Folding bikes or frames designed for traveling can cost even more. But it is still possible to get an affordable American-built frame on a Bike for the Rest of Us.

Bike Friday has been building frames for small-wheeled, foldable bikes in Eugene, Oregon for the past 22 years, and have gathered something of a following for their unique, customizable designs. Although most of the models do not fold as quickly and compactly as a Brompton folding bike, they are all designed to fit in a standard-sized suitcase for plane or train travel. A high-end Bike Friday with expensive components will cost $2000 or more, but they now offer an entry-level model with the same type of frame, hand-made in Oregon, matched with affordable parts (and an 8-speed rear derailleur), for as little as $798

They will add fenders, a kickstand, bell, and rear rack for a nearly complete 8-speed Bike for the Rest of Us priced at $920.95: the Pocket Companion (above)
They also will build you a "New World Tourist Nexus 8" with the premium "red-stripe" 8-speed Shimano nexus internal gear hub and rollerbrakes, Schwalbe Marathon tires, rear rack, fenders, kickstand, bell, water bottle, and a high-end front dynamo hub for about $1700 (not including the price of lights). The bike pictures has the Nuvinci hub instead:

And at the high end there is always the Infinity Drive Silk, with a Nuvinci continuously variable internal hub, Gates carbon belt drive, front and rear racks, and optional dynamo lighting for $2700.

Bike Friday makes it very easy to customize each of their models, or design a completely unique bike for people with special needs, so all of their models could be shipped to your door with a full complement of fenders, kickstand, dynamo lights, racks and bell, if desired. The Pocket Companion is cheaper due to using standard parts.

Here is the Silk 8sp (slct) with a Shimano Alfine hub and full dynamo lighting system:



They just unveiled a new "long-tail" cargo bike model, stay tuned for more about this.

Bikeshare

A New York City citibike. Credit: citibikenyc.com
For me, the biggest surprise of the last 6 years was the way that bikeshare took off in the Washington, D.C. region and how it has spread to New York City and other cities in North America. Bikeshare is the ultimate in Bikes For The Rest Of Us.

Here's a must-read: David's post about his father, who had not owned a bike in 37 years, trying bikeshare. With bikeshare, you don't have to own a bike to reap the benefits of bicycling as basic transportation.

Honorable Mention: Folding bikes can be very useful in this age of multimodal transportation. Read Tom's review of his Dahon Eco-3.

Montague Boston 8

Montague Boston 8.  Photo Credit: Montague Bikes.
Montague's Boston 8 is a folding bike that features a Shimano Nexus internal 8-speed hub and 700c tires and folds up to fit in your trunk or on a bus or train.  The MSRP is $1050.

Montague has a storied history.  Harry Montague was a Washington, D.C. bike commuter who built a full-size, foldable mountain bike in his garage in the early 1980s.  According to his Washington Post obituary (Montague died in 2011), Montague wrote letters to 40 bicycle manufacturers about his design, but no one was interested.  He then started his own business with his son building custom foldable bikes. 

In 1997, Montague made a "paratrooper bike" for the U.S. military that has been used in Afghanistan.  The paratrooper bike has been on display at the America on Wheels Transportation Museum, and it is for sale to the general public as well.

The Boston 8 and the single-speed Boston are perfect for multi-modal commutes and for travel.  Here are the 2013 specs for the Boston 8 and a video introduction:
