Nada más tener conocimiento de la aparición de una serie de trampas para ciclistas y senderistas en montes de Verducido, el Seprona de Pontevedra ha abierto una investigación para dar con la persona que los colocó y para determinar si estar actitud puede tener reproche penal o administrativo. Las indagaciones se centran en cables colocados a la altura del cuello y tablones en el suelo con clavos.
Tras precisar que este tipo de pesquisas suelen ser «moi complicadas», desde la Guardia Civil hicieron un llamamiento a la colaboración ciudadana para erradicar estos comportamientos, e insistieron en que es preciso que aquellas personas que se encuentren con trampas deben comunicarlo inmediatamente al Seprona.
Ayer, uno de los obstáculos denunciados -un cable de acero colgado entre árboles a la altura del cuello- no había sido retirado. De hecho, ya por la tarde, un miembro del Club Ciclista Farto se desplazó hasta el sendero para señalizar con cintas esta guillotina.
Por su parte, José Carlos Morgade, secretario de la mancomunidad de montes de Pontevedra, dejó muy claro que se trata de actuaciones «extremas que se deben rexeitar». En todo caso, precisó que hay quienes creen que «poden andar polos montes coas motos, cos quads, coas bicicletas. Teñen que entender que os propietarios non teñen a obriga de ter as pistas como camiños públicos, porque non o son, son pistas para servizos dos propietarios».

Impossible electric bike folds up to fit in a backpack

When folded up, the Impossible bike measures 17 in (43 cm) tall
Folding and electric bikes have proven fertile ground for innovation recently, but what about bikes that are both electric and foldable? Three years in the making, the Impossible bike from a team of China-based engineers folds up to fit in a backpack and is capable of reaching 12 mph (20 km/h) on the road courtesy of a brushless electric motor.

A folding bike has obvious appeal, with the compact design allowing users to store it under a desk at work, lug it on public transport or throw it in the car. But you do wonder, how much does a collapsible design compromise pedaling efficiency and the overall riding experience?
Whacking an electric motor onto the frame goes some way to negating this dilemma, and the Impossible team certainly isn't the first to take this approach. Back in 2010 we featured the VeloMini electric bike, which folds up to around the size of a guitar case. More recently we looked at the Gi bike that not only folds up, but uses its electric motor to charge the rider's phone.
What the Impossible does promise is a new level of portability. It weighs under 11 lb (5 kg) and when folded up is 17 in (43 cm) tall, just a few inches bigger than the laptop on which I'm writing this story. It runs on ten 2,900 mAh batteries that can be recharged from a regular wall outlet and has a range of 15.6 mi (24.8 km).

The engineers have taken a somewhat circular approach to the design of the bike. Made primarily of anodized aluminum, it comprises four circles which fold out to form both the wheels and the bike's frame. The team claims that this spreads the rider's weight evenly across the bike and allows it to support a maximum load of 180 lb (85 kg).
Another space-saving measure is the combining of the seat and carry case. As the saddle is detachable and shaped to fit the folded bike snugly inside (the seatpost and handlebars notwithstanding), it protects the batteries and motor from the elements should you need to store it outside.
The Impossible Technology team behind the bike says the concept still needs some refining before it is taken to market and is currently running a Kickstarter campaign through which it hopes to raise funds to further develop the brushless electric motor. For its prototype, the team modified an existing electric motor, though it says the final version will feature an ultra-thin motor designed specifically for the Impossible.
Pledges start at CAD$430 (US$377), with the bike available in white and black. Shipping is estimated for August 2015 if everything goes to plan.
Circa Cycles takes a modular approach to keeping costs down

Circa Cycles' aluminum frames incorporate time- and labor-saving MABEL lugs
Like a lot of other American products, most US-brand bicycle frames are made overseas, in countries where manufacturing costs are lower. Portland, Oregon's Circa Cycles, however, wants to build its higher-end bikes stateside, yet still sell them at reasonable prices. It plans on doing so using a unique frame-construction process, known as MABEL.

Ordinarily, a given make/model of bike is pre-manufactured in a variety of frame sizes, with the hope that they'll all eventually be sold. By contrast, Circa envisions a system in which potential buyers will go into a showroom, check out the bikes on display, and then order one to be made in their selected size. Of course, made-to-order bikes do already exist, but they're typically made by hand and are thus very expensive.
MABEL – or Modular And Bonded Endless Lug – gets around this problem utilizing lugs (the bits that join the tubes together) that are made from individual CNC-milled aluminum components. When a frame is ordered in a given size, a combination of components is selected for each lug, in order to create the desired angles at each frame junction.

Those components are joined to one another – and to the ends of the tubes that go into the lugs – using an aerospace-grade structural adhesive, along with a proprietary mechanical feature which is hidden inside the lug. Normally, aluminum frames are welded together, but doing so takes much more time and labor.
"The combined system provides enhanced strength, a very clean aesthetic and very fast assembly times," Circa founder Rich Fox told us. "This last piece is critical to our ability to be price-competitive, as well as being able to deliver something really unique: once we’re fully up and running, we’ll be able to go from zero to bike in less than 10 days."
Additionally, the lugs and tubes are finished using an anodizing process, eliminating the time and expense involved in applying paint.
The Road version of the Circa Trillium
Circa plans on starting with Road and City versions of its Trillium bike, with dropped and flat handlebars respectively. At a weight of 21 lb (9.5 kg) and outfitted with Shimano 105 parts, the Road will be priced at US$2,000. The more utilitarian City will feature an 8-speed internal shifting system, and sell for $1,800 – although a special-edition premium-outfitted Goldie City is also being offered for $3,400.
Fox told us that he's currently setting up his first showroom in downtown Portland, with client appointments starting late this month.
