Breezer’s NuVinci-Equipped Uptown Infinity Commuter Bicycle Now Available

breezer uptown infinity commuter bicycle with nuvinci 360 infinitely variable internal planetary geared hub

Breezer’s Uptown Infinity, their top of the line commuter bike, is now shipping. Designed to offer every convenience and utility one may need for getting to and from work or errands, the big premium on the Infinity version is the use of Nuvinci’s 360 internal planetary geared hub that offers an infinite range of gearing between the hardest and easiest settings. Simply twist the dial (which is pretty effortless) and the effort changes instantaneously and without fuss. If you’ve never ridden one, it’s pretty smooth, and since it’s all enclosed in the hub, should be virtually maintenance free.

Highlights include full fenders, rear rack, full chaincase guard and integrated Busch & Muller dynamo powered head and tail lights, which are considered to be the best and brightest of the category. Most of the cockpit is Breezer branded alloy bits, including a suspension seatpost. Cranks and front dynamo hub are Shimano.

Lastly, it includes an AXA solid ring lock built into the seatstays to make quick coffee shop pit stops easier. Engaging the lock immobilizes the rear wheel. Price is $1,269, and it’s available in a low-step frame version also, shown after the break…

Nuvinci Unveils New N360 Internal Planetary Gear Hub – Lighter, Better Gear Range

Nuvinci / Fallbrook Technologies’ new N360 hub drops size and weight while increasing its gear range over their original model. In the process, they seem to be picking up quite a bit of regular and e-bike OEM placements both here and afar.

Gepida, Mosquito, Raleigh, Victoria, Ellsworth, Breezer and Organic have all spec’d the new N360 on their bikes for 2011. The system will also be available as an aftermarket kit for those wanting to convert their current cruiser or commuter.

The system uses a CVP (continuously variable planetary) transmission that replaces gears with spheres. This gives it an infinite number of ratios between the lowest and highest setting. There is a 360º range of gearing available, which is slightly less than the 409º on Shimano’s new 11-speed Alfine, which relies on individual gears.

The new N360 reduces the amount of shifter rotation required to change the ratio, and it shifts easier under load. For e-bikes, being able to shift when stopped will help reduce power usage by getting into an easier gear for takeoff without having to be moving to change.

Nuvinci Releases New Continuously Variable Internal Gear Bicycle Hub

PRESS RELEASE: Fallbrook Technologies Inc. (Fallbrook), a technology company dedicated to improving the performance and flexibility of transmissions for engine- and human-powered devices, today announced and displayed its new NuVinci 360 CVP bicycle drivetrain (N360) at the Taipei Cycle show in Taipei, Taiwan.

The N360 represents a major update and enhancement of the NuVinci bicycle drivetrain. As with previous NuVinci hubs, the N360 uses spheres instead of gears to transfer torque, but the number of spheres has been reduced from eight to six.

The N360 is 30% lighter, weighing just 2,450 grams (5.4 lbs), and has a 17% smaller overall diameter than previous NuVinci models. Shift effort is significantly reduced, even under high pedal forces. Nominal ratio range is 360%.

The N360 also provides an enhanced shifting interface. There is a more direct feel for the rider, with 50% less shift grip rotation required between the lowest and highest ratios. Because shift effort under pedal torque is also less, riders can shift easily at any time, in practically any condition. The sleek, newly-designed shifter and shifter display now includes the icon of a rider on its unique “inchworm” indicator. Additionally, the new hub interface is inside rather than outside the frame dropout, reducing the likelihood of damage in the event of a fall.

Road to NAHBS 2014: Rob English Electrifies Things

Rob English Cycles custom e-bike with Bosch motor and Gates Belt Drive transmission

Over the years, Rob English has shown us some of the lightest bikes around, which is saying a lot since he builds from steel! And usually, at least one of the very impressive bikes in his booth is for himself. And those bikes usually push the limits of what’s possible to streamline aerodynamics and shave grams. Look here, here and here for examples that’ll blow your mind.

This year, at least one of his bikes will be heavy, yet still likely very quick. The big guy shown above is part of the Gates Belt Drive e-bike competition at the show.  In his own booth, look for While he won’t have his own booth this year, opting to just send the motorized beaut for Gates’ expo, here’s what else he’s been up to along with several customer bikes…

BIKERUMOR: What are your main building materials?

ENGLISH: Fillet brazed steel with the occasional carbon or titanium tube.

BIKERUMOR: What’s new with your company since NAHBS last year?

ENGLISH: Up until last year’s show I was still working part time as the engineer for Bike Friday. Shortly after I made the decision to concentrate full time on English Cycles, and also to support my wife’s new venture of Velo B&B. The extra time has enabled me to build a few more bikes and take on some additional design work.

REI Lightens Up the Gotham, Launches The Arkham Belt Drive Commuter and Barrow Cargo Bike plus Barrow Basket

2014 REI Novara Gotham profile

In 2012 REI dropped the Novara Gotham on us.  At the time, it was a steel framed, belt drive commuter making use of the NuVinci N360 internally geared hub.  The bike was pushing 41 pounds fully kitted with a rack, fenders, and lights.  For 2014, REI (and house brand Novara) looked to shed some pounds.  To do this, the frame is now produced in aluminum, dropping the weight to around 34 pounds.

The bike still comes specced with the N360 rear hub and a belt drive.  Tektro Gemini hydraulic disc brakes and included fenders should make dealing with the rain more palatable.  The included rack, plus front and rear lights make this a turn key commuter right off the store floor.  There are three sizes to choose from, and MSRP is set at $1399.

Head past the break for the Gotham’s sibling, the Arkham, plus the new Barrow cargo bike and basket.

IB13: Fatbike Round Up – The Big, The Odd, The Motorized

fatbike roundup (23)

If it wasn’t cloaked in hi-viz yellow this year at Interbike, chances are good there as a fatbike near by. Fatbikes have hit the industry in a big way, moving from a niche bike in the extreme North, to the next bike I need to buy after a cyclocross and an Enduro bike (once Enduro fatbikes hit the scene, it’s all over). Why so popular? Orginally designed for snow and sand, fatbikes offer gobs of traction and float in situations where other mountain bikes would flounder. That, and it’s impossible to ride one without a huge smile plastered across your face.

Love it or hate it, fatbikes are here to stay. Check out some of the highlights after the break.

SOC13: New City & e-Bikes from Swobo, Stromer, Kreidler & Breezer

Swobo-folsom-coaster-brake-urban-dj-bike01

Mountain bikes with 650B wheels were definitely the predominant theme at Sea Otter this year, there were plenty of other cool things for city dwellers, commuters and those that get to traverse a bit of dirt before becoming a city dwelling commuter.

Swobo has added variations to their existing bikes, a highlight being the Folsom. It’s essentially a coaster brake equipped adult BMX bike for playing in the concrete jungle. The frame is an oversized round- and box-section alloy tubed skid machine with a matte black finish, just like when you spray painted yours in the garage as a kid. The complete bike is just $589.99, framesets are also available. New for 2013 is that the frame’s belt drive compatible and has removable cable guides.

At the opposite end of the spectrum, we have a couple e-bikes and a slick new belt-driven Breezer…

Autobike Builds First Continuously Variable, Automatic Shifting Bike

Autobike's New Auto Shift Goes Electric, No More Wheel Weights

Who remembers the Trek Lime? Or for that matter the original Autobike (not sure if they’re related)? It seems that the holy grail for bike designers is a bike that appeals to the masses not because it’s the lightest, or fastest – but because it’s the simplest to operate. So, first there was the Autobike (that are going for $799 on ebay!) which was quite the bike. Equipped with centrifugal weights on the rear wheel and a Low-Normal rear derailleur that was attached to said weights, the rider would start pedaling causing the weights to spin outwards which in turn shifted the derailleur to a harder gear. Stop pedaling and come to a stop, the weights would return shifting the bike into an easier gear to get started. Quite the Rube Goldberg contraption, the whole design was actually fairly clever. Too bad it didn’t work. Pedaling at certain cadences would leave it in between gears, the gearing was usually off, and the as-seen-on-tv nature of the thing caused most to be horribly assembled and destroyed on the first ride – at least the only bikes we ever saw in the shop were broken.

Then came the Trek Lime – which was a great bike, though it wasn’t perfect. The Lime did nearly everything right with the exception of the 3 speed internal hub that seemed to turn potential customers off. Apparently not wanting to shift, didn’t necessarily mean they didn’t want gears.

Which is where the new Autobike and NuVinci step in with the first automatic shifting, CVP equipped bike that we know of. Thanks to a 360 percent gear range and smooth, automatic shifting – the new Autobike shows a lot of promise.

More details, pricing, and video after the break!
