PBE16: Seven Cycles carbon and Ti “Edition of One,” sleek flat mount dropout

philly-bike-expo_seven-1

According to Seven brand and sales manager, Craig Gaulzetti, everyone at Seven has bike side projects. “However you can love bikes more or be more passionate about them, do it.” This explains why it is home to ten or so builders who, outside of the company walls, build under their own brands. Craig himself has a brand, Gaulzetti Cicli. Another builder from Seven, Bryan Hollingsworth, was also exhibiting at the show under Royal H.

Boasting a special status as the world’s largest custom bicycle manufacturer, Seven claims 35,000 custom steel, titanium, and carbon frames over its history. The brand continues to push the depth of their capabilities; their SL and SLX level, titanium tubing is externally butted to tailor the geometry and ride-feel to each customer’s particular need.

And at Philly Bike Expo, they shared their latest “Editions of One” project, where Seven designers and builders create one-off bicycles to challenge their status quo. This year, the bike is an homage to bicycles at the beginning of the 20th century, complete with custom cockpit and a proprietary drivetrain.

Story about a Prince: Part 2

In Part 1, I discussed the reasoning behind buying a custom bike. In this installment, I’ll discuss the process of building the frame into what you see here, the Philly Bike Expo build. 

When we left off, I was off in Portland, riding my naked Peacock Groove around in the rain.

Riding a custom bike that is literally rusting beneath you can be an intense experience. On one hand, I think corrosion is beautiful, and there is something kind of poetic about riding a bike that is constantly morphing through chemical change beneath you. It really only looks the way it does at that exact moment. A day later, there will be new or different rust. Your legs polish the top tube as you ride it. It develops a patina that shows where the frame has been impacted by your body or the elements.

On the other hand, you know that tubing is pretty gosh-darned thin… and you’re basically hurting it by riding it this way.

PBE16: Ground Up Speed Shop’s Eric Baar discusses his velodrome hot rod

philly-bike-show_ground-up-speed-shop_eric-baar-3

philly-bike-show_ground-up-speed-shop_eric-baar-1

Eric Baar’s day job is laying perfect beads for daVinci tandems in Denver, Colorado. When he’s in his personal shop, the skunkworks at Ground Up Speed Shop in Colorado Springs, he’s there to have fun- which is what makes his bikes so exciting. Eric approaches his bikes the way he does his race car. They are flashy and exuberant expressions of the machine and the sport, as well as his level of mastery as a craftsman. This means exposed welds, metal flake and pinstriped finishes, and experimental interpretations of existing componentry.

For the Philly Bike Expo, Eric treated both himself and the public to his new personal bike, his new interpretation of a velodrome speed machine. With the exception of the saddle and the handlebars, every component on the build has been modified or built from scratch for his specific intents. The front aluminum triangle is the culmination of years of track frame innovation in aluminum. The rear triangle, in titanium, is heavily influenced by hot rods- to the point here the joints literally look hot. What’s most evident is that Eric built this bike so that he, as a craftsman and artist, could have a long and beautiful relationship with it. It will change and grow and become more pinstriped and outrageous over his time riding and playing with it. This bike is simultaneously a proving ground and a sketchbook for Eric.

Rather than try to speak for Eric, I interviewed him on the Philly Bike Expo show floor.

X-Shifter’s universal wireless shifting kit goes live

xshifter-universal-wireless-bicycle-shifting-upgrade-kit

At Interbike, we spotted X-Shifter roaming the grounds with their wireless shifting upgrade kit that turns any derailleur into a wireless, quasi-electronic shifting one. Whether it’s for road or mountain bike, anything from base level up to premium units, X-Shifter connects to them and gives you control with a single thumb pad to manage both front and rear shifts.

Since we first saw them, they’ve added a road specific shifter unit, upgraded their software to include multi-shifts, optional control of both front and rear shifting in an optimized sequence for you, and added in a few more customization options that could be coming soon…

DCA Design’s helmet concept gives you a 360º view with heads-up display visor

DCA Optic

DCA Design, a Warwick, UK based industrial design firm, has put forth a prototype bicycle helmet dubbed Optic, offering a rear facing camera and a drop down visor with display capabilities. An onboard computer projects data onto the clear visor, allowing the rider a 360 degree view when the rear facing camera is displayed on the visor. The option of overlaying other data, such as navigation or hazard warnings, brings the Optic into the realm of augmented reality.

Performance data could also be displayed along side real time race stats, however, in it’s current conceptual form, Optic is geared towards bike commuters, which is no surprise as DCA Design’s portfolio includes things like trains, insulin injection pens and other consumer interface/ergonomic solutions. For now it’s focused primarily on issues of safety and convenience, offering navigation, the ability to see what’s behind you, proximity detectors (blind spot monitors) and obstacle monitoring.

Who can forget the wild looking Scurra Hard Enduro? It’s been three years since we first caught a glimpse of the wild looking bike at Interbike 2013, but by the looks of things, Scurra is still working to perfect their Trelever suspension. Taking to facebook with news of a version 2.0 with completely redesigned suspension, Scurra says that the newest version could be up and running soon…

E-bike Madness: A sea of batteries and motors from Friedrichshafen to Las Vegas

bmc-ebike-concept-olympic-gold-bike-greg-van-avermaeteurobike-2016-78

With each annual edition of the tradeshow season, there seems to always be at least one discernible trend. Manufacturers and the industry seems to latch onto a concept in lock step and then all of a sudden it’s the show of 29″, 650b, fat bikes, and now plus bikes. E-bikes are a little different. For years, they’ve been there. Silently charging in the background just waiting to take over the world. Ok, that might be a bit dramatic, but we have been seeing e-bikes at trade shows for years, but this year stood out.

Eurobike has always been a haven for e-bike technology, but for 2016, Interbike had almost an entire wing of the show floor devoted to anything and everything with an electronic motor. So what does that mean for the future? From what we saw at the show, it seems that most manufacturers feel that they can no longer ignore the category. Considering brands like BMC were showing off elaborate prototypes of future e-models, there are a lot more companies building e-bikes than just a few years ago. The depth of the e-bikes at the two shows also serves to highlight just how vast the difference between separate motor technologies can be. Some bikes provide just enough boost to feel like you’re having a great day on the bike, while others shown were literally electronic street motorcycles.

It’s not all doom and gloom though. While there certainly were some WTF machines, the majority of the bikes seem to be headed in the reasonably powered, pedalec direction (meaning you have to pedal). After all, a throttle is the only thing that separates an e-moped from an e-bike (pedalec)…

Wooden Widget helps you build wooden bikes and trailers at home

wooden-widget-hoopy-1

We’ve seen a number of different wooden bikes over the years from things like DIY bamboo kit bikes to sculpted, laminated bikes to super refined hardwood/carbon and bamboo/carbon composite solutions, but this bike looks to try to be even more accessible. Wooden Widget’s ethos is to provide various modes of transportation that can be easily fabricated at home out of wood by any moderately skilled wood worker with easy and affordable tools. Of course no home-made transportation company’s catalog would be complete without a bicycle, but Wooden Widget takes it even further with some other creative and useful applications…

World’s Funnest Bike Part III: Built ridden & reviewed… plus video! Now, SHOW US YOURS!!!

Playground 000 b Cranks (3)

Here it is in all its colorful glory. To be honest, I wasn’t sure how this bike was going to ride or how it would look once the parts started flowing in… especially with my wheel choice(s). At first, I didn’t really care if something didn’t match as we often get things in for testing that aren’t all matchy-matchy with the rigs on hand. Once the first few pieces came in (black/blue EPO frame, black/yellow wheels, Kawasaki green DVO fork…), well, now I was on a mission!

Check out the final build & ride review, lots of pics, plus a really “cinematographic” video of the bike in action…
