BULLITT Cargo Bike

BULLITT Red
While a number of North American designers have developed "longtail" cargo bikes, where the kids or freight are carried in back, the Dutch and Danish prefer keeping things up front. LARRY VS HARRY, a shop in Copenhagen, designed the BULLITT to be a relatively light-weight and speedy way to transport cargo and children.

Most of the models come standard with a 7 or 8-speed internal gear hub in the rear, disc brake in the front, a custom kick-stand and fenders. Derailleur gearing and e-assist are also available. The riding position is somewhat leaned-forward, especially for taller riders, and there is no step-thru frame option. The modern-looking aluminum frame is meant to be extra stiff, to prevent twisting even with heavy loads.


I had a chance to test-ride this bike alone and with kids in the front (in a version that has an added kid seat); the handling is similar to a road bike, with responsive (or twitchy) steering which takes a minute to get used to. Disc brakes are a good idea on a bike meant to carry weight at high speeds.

Many of the Bullitts in the USA are sold by Splendid Cycles in Portland, Oregon, but they are also available in a few other cities. The bike comes as shown, but most people pay for a child seat or cargo box to be added, and an electric bike version with a lithium battery pack is also very popular. A frameset costs $2350 alone. The complete bike with Alfine 8-speed hub is $3500. The e-bike version with a BionX rear hub is a grand more, $4500. Dynamo hubs and lights are an option.


Due to the relatively narrow cargo deck (no wider than the handlebars), one child can fit easily, but only small kids can double up.  Winther, another Danish bike company, makes an adaptation of the Bullitt frame called the Wallaroo, which has a wider child carrier included, to fit two kids side-by-side. However, there is only one current USA dealer, JC Lind in Chicago.

Kinn Cascade Flyer

Kinn is new company with 1 model of family oriented bike in Oregon. The frame, wheels and many other parts are made locally.

The Cascade Flyer is part of a new class of bikes called "mid-tails", shorter and lighter than a "long-tail" cargo bike, such as Yuba Mundo or an Xtracycle, but long enough to carry a kid plus a couple of panniers. And it comes with everyone you need, except for lights: integrated rack, fenders, chainguard, dual kickstand, 8-speed internal gear hub, disc brakes and a leather saddle.


The designer wanted a bike that was sturdy and long enough to carry his grandkids along with a couple of bags of groceries, but short and light enough to ride to work and around town. It also is just short enough to fit on a bus rack for bikes, with the front wheel turned backwards: this explains the curve in the down-tube. The geometry is designed to handle similarly to a modern hybrid or city bike, with 72 degree frame angles, and full-size 700c wheels (built by hand in Portland).

Front wheel twists so the bike can fit a standard bus rack
The 8-speed Alfine IGH version costs $2350 for a complete bike as shown. A 27-speed derailleur option is the same price. Unfortunately, there is no small size; riders shorter than 5'2" are out of luck, but medium to tall people should fit.

This can be a good option for a person who wants a made-in-the-USA, fully equipped bike that can haul groceries and a kid, and also serve as a commuter bike and city bike. I wish the complete build included dynamo lights. Considering that the wheels are hand-built locally, it may be possible to add this on to the order for an additional cost. If not, the front wheel should sell easily on Ebay.

You also get some fancy extras, like the bamboo rack top with hidden lockbox:

Biria CitiBIKE

Biria CitiBike 700C Step-through 3 Speed - Orange
While priced the similarly to most entry-level hybrids ($545 shipped from an online shop), the Biria CitiBIKE is much more useful, due to the inclusion of a front rack and rear rack, full fenders, a kickstand and a chainguard, with a 3-speed internal gear hub. A 7-speed derailleur version is also available. The components are not the most expensive, but should be reliable if looked over by a quality local bike shop. And the steel frame, especially the step-thru version, has a timeless look, and should last if you don't leave it out all winter.

Like this diamond frame, the step-thru is also available in a lovely sky blue; the fenders are also painted on that model, unlike the silver fenders on the diamond frame model:

Specifications:

Frame:  Hi-ten Steel, with cromoly seat tube
Fork:  Steel Unicrown
Rims:  Aluminum, black with CNC wall, 700c
Tires:  700c x 32 mm, Tan or black
Front Chainrings:  Single

[But note the real bike has linear cantilever brakes, not roller brakes]
We previously mentioned the unusual looking Biria Easy Boarding bike, which is also still available.

Xtracycle Edgerunner

Xtracycle Edgerunner 27D Lux XO

Continuing our overview of cargo bike options, the relatively new Edgerunner is a Longtail cargo bike from Xtracycle.

Xtracycle founded the current Longtail cargo bike craze, with their FreeRadical. This frame extender attached to a standard bike, converting it to a longtail. An ecosystem of accessories, bags, decks, lights and kickstands was developed around this standard, which Yuba later adopted for their Mundo bike, as have some other manufacturers. Now Xtracycle is making their own complete bike, the Edgerunner. 

The 27D Lux features fenders, a double kickstand, disc brakes, a front dynamo hub and high-end dynamo-powered lights. It has a 3-speed front and 9-speed rear derailleur, for a wide range of gears. 
It uses a smaller, 20 inch rear wheel to keep the center of gravity lower. This make it easier for kids to mount the bike by themselves, and improves handling with carrying heavy loads. It also lowers the effective gearing, which will be a big help when hauling 2 kids and a week of groceries.


Options include huge cargo bags for the rear rack, rails for kids to hold, toddler seats, hydraulic instead of mechanical disc brakes, internal gear hub, and electric assist with the BionX system. The price can vary from $1500 for the basic 24D, to $2500 for a special version with Alfine 8-speed hub at Splendid Cycles, to $2900 for the 27D lux with dynamo lighting and high-end derailers. E-assist is $1000 extra.

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.

Jamis Commuter 4 - 2011


Jamis Commuter 4 - winter blue - 2011
For 2011, the Jamis Commuter series has been updated. We previously reviewed the Jamis Commuter in 2008, when the Commuter 4 was equipped with a derailer set-up. Now the top-of-the-line Commuter 4 sports an 8-speed Shimano Nexus hub, a rear rack, and a headlight powered by a front hub dynamo, for only $750. 

Unfortunately, the flat fenders and thin chainguard are still there, more for style than for function, and the riding position is rather leaned-forward, in the Hybrid bike form. But for someone who lives in a dry climate and likes that riding posture, this is a good-looking bike that will get you home safely at night, and it's a good deal for a bike with an 8-speed internal gear hub and a hub dynamo.
Jamis Commuter 4 - step-thru, white

The women's version, common on hybrids, is not my style, but may be perfect for someone who wants the lower standover, but does not like the swoopy, loop frame look.

Jamis provides plenty of information about components and geometry:

Unfortunately, the 14" and 18" women's frames do not have the geometry listed, but it should be similar to the 15" and 19" diamond frames. The rather steep seat tube angle and the low, straight handlebars lead to a half-leaned-forward position.


A derailer version is still available on the Commuter 1
