Gtech e-bike review: Like a normal bike, except you feel like you're incredibly good at cycling

The Independent

Technically, an e-bike is a normal bicycle that also includes a battery that gives you a push, but in reality it's nothing like that. In reality it's like a wizard: able to summon winds behind your back to propel you, like making yourself roughly twice as strong and fit as you really are, or like getting a backie from a friendly ghost. You pedal as normal, but when you do it triggers a computer that starts the motor whirring at the same time, propelling you along; when you reach 15mph, the law requires that it stops helping you, but it will kick back in when you slow down. Gtech's e-bike manages this magical act even better than most, by virtue of looking like a real bike. Some of its rivals embrace the fact that they are something towards a moped, with visible batteries and plenty of wires and weight; the Gtech model has all that, of course, but packs it onto a frame that looks like a normal push bike.


China Mobile Payments, AI, Bike-Sharing, Short Videos All Make The Meeker Report

Forbes Technology

China tech is highlighted regularly in Mary Meeker's annual Internet report that underscores China's advances in mobile entertainment and payments, e-commerce, artificial intelligence and on-demand transportation -- in other words, all the latest trends that define Chinese innovation today. If you want evidence of China's climb, consider that nine of the world's top 20 Internet leaders ranked by market valuation are in China today: Alibaba, Tencent, Ant Financial, Baidu, Xiaomi, Didi Chuxing, JD.com, Meituan-Dianping and Toutiao. The remaining 11 are in the U.S. led by Apple, Amazon, Microsoft, Google (Alphabet) and Facebook. China's momentum in artificial intelligence is also highlighted with notes on Chinese government support for AI development. The report cites Eric Schmidt's prediction that China could be at the level of the U.S. within five years, considering how fast Chinese AI knowhow is improving.

It's a nice 20 mile ride, but there's a problem: you've never ridden a bike before!To make matters worse, you are new to the Bay Area, and all you have is a good ol' fashion map to guide you. How do you get started? Let's first figure out how to ride a bike. One strategy would be to do a lot of studying and planning. Read books on how to ride bicycles.


How This Startup Used A Robotic Arm To 3-D Print A Bike

Forbes Technology

Arevo is using the bike to demonstrate its unique, three-pronged approach to 3-D printing. The process starts on a computer screen, where parts are designed and tested. Next, the company uses a "deposition head" attached to a robotic arm to carry out the printing itself. The technique, which Arevo calls "True 3-D printing," allows material to be layered in any direction to create parts of almost unlimited size. This is because the free-moving robot printer is not constrained by the dimensions of a printing unit.


Shopping Carts Are Coming To 'Fortnite: Battle Royale'

Forbes Technology

Epic Games has announced the imminent arrival of Shopping Carts to Fortnite: Battle Royale. The new item will almost certainly roll into the game early Tuesday morning with the next big update. Shopping carts are coming to Fortnite soon. 'Roll into battle alone or with a buddy," the item's description reads, though we don't know much more than that at this point. However, this does sound like the first actual vehicle (of sorts) players can drive in Fortnite.


This 3D-printed bicycle is stronger than titanium

Mashable

The Arevo bicycle looks and feels like a high-end commuter bike, but it was made using 3D-printing technology and software. It's being hailed as the first truly 3D-printed bicycle. The Bay Area-based "additive manufacturing" company (that's what engineering-level 3D printing is called these days) made the fully functional bicycle as a proof-of-concept to show that the thermoplastic material, laser-heating, and robotic 3D-printing process can be used to replace metal parts for defense companies, airplanes, fighter jets, electronics, and more. The bicycle frame was made in one piece and eventually other parts of the bicycle could be printed, as well. It took about two weeks to build the bike -- which is a lot quicker than the usual labor-intensive method of piecing together carbon fiber strips.


The 3D printed bike: Silicon Valley startup reveals carbon fiber frame

Daily Mail

After a career that included helping Alphabet Inc's Google build out data centers and speeding packages for Amazon.com Inc to customers, Jim Miller is doing what many Silicon Valley executives do after stints at big companies: finding more time to ride his bike. But this bike is a little different. Arevo Inc, a startup with backing from the venture capital arm of the Central Intelligence Agency and where Miller recently took the helm, has produced what it says is the world's first carbon fiber bicycle with 3D-printed frame. Arevo is using the bike to demonstrate its design software and printing technology, which it hopes to use to produce parts for bicycles, aircraft, space vehicles and other applications where designers prize the strength and lightness of so-called'composite' carbon fiber parts but are put off by the high-cost and labor-intensive process of making them.


The Vehicle of the Future Has Two Wheels, Handlebars, and Is a Bike

WIRED

Well, there are plenty of candidates! We've got the self- driving car and drones big enough to carry people. Elon Musk is getting ready to bore hyperloop tunnels. When it comes to moving humans around, the future looks to be merging with sci-fi. But from where I stand, the most exciting form of transportation technology is more than 100 years old--and it's probably sitting in your garage.

"For people who bike, we know this is particularly an issue because we know as objects on our street, people on bikes are a little bit harder to recognize and predict," he says.
