There are all sorts of bike locks. There's the cable lock, the U-Lock, the industrial chain, the looped-string-secured-with-a-combo-lock — and now, there's a keyless lock whose developers hope it can create a new Airbnb-type market for two-wheeled transport.

The Skylock isn't the world's first keyless bike lock, but it's uniquely innovative in other ways. It's coated in solar panels to charge the internal Bluetooth that serves as the locking mechanism, and it can hook up to Wi-Fi networks to boost the Bluetooth range and send for help if you take a spill. Skylock owners can also program time-sensitive passwords into an accompanying app, essentially allowing them to rent their locks, and bikes, to anyone.

The lock's makers, Velo Labs, have launched a $50,000 crowdfunding campaign to bring the technology to the streets. "If you wanted to start your own informal bike-share, it's completely possible right out of the gate," Velo Labs co-founder Jack Al-Kahwati tells NPR. Jon Terbush

"We have made a lot of progress as far as denuclearization is concerned and we are talking about a lot of different things. Things are going very well with North Korea," President Trump told reporters Saturday of his Friday conversation with North Korean negotiator Kim Yong Chol.

"That was an incredible meeting," Trump said. "We've agreed to [another summit between Trump and North Korean leader Kim Jong Un], probably the end of February. We've picked a country, but we'll be announcing it in the future. Kim Jong Un is looking very forward to it and so am I."

Vietnam, Thailand, and Singapore are thought to be under consideration for the summit's location. Read a "plausible roadmap to peace with North Korea" from The Week's Harry J. Kazianis here. Bonnie Kristian

At least 66 people were killed and dozens more injured Friday when a fuel pipeline in Mexico exploded after being ruptured by fuel thieves. Some 85 people not included in the current death toll are listed as missing as of Saturday morning.

A crowd of people had gathered to collect the spilling fuel in plastic containers when the fireball occurred. Local authorities said the death toll could continue to rise given the severity of the injuries and the number of people whose whereabouts remain unknown.

Illegal pipeline taps like this one, which occurred near the town of Tlahuelilpan about 60 miles north of Mexico City, are a chronic problem in Mexico; an average of 42 taps were drilled daily in the first 10 months of 2018. "Far from stopping the fight ... against fuel theft, it's going to become stronger," said Mexican President Andres Manuel Lopez Obrador on Saturday. "We'll continue until we've eradicated these practices." Bonnie Kristian

Jason Van Dyke, the Chicago police officer convicted of second-degree murder and 16 counts of aggravated battery for his fatal shooting of a black teenager named Laquan McDonald in 2014, was sentenced Friday to six years and nine months in prison.

With good behavior, Van Dyke could be out of custody in three years or less, his lawyer said. The special prosecutor who handled the case had requested a sentence of 18 to 20 years, and the sentence Van Dyke received is for the murder charge alone, not the battery. Each of the battery convictions had a mandatory minimum sentence of six years, and the judge could have ordered them to be served sequentially.

On Thursday, three other officers accused of falsifying reports to justify the shooting were acquitted. Bonnie Kristian

For once, President Trump is really happy with Special Counsel Robert Mueller.

He responded with a flurry of tweets Friday and Saturday to Friday evening's news that Mueller denied a BuzzFeed News report alleging his investigation had compiled evidence Trump directed Michael Cohen, his former personal attorney, to lie to Congress about the Moscow Trump Tower project.

Many of Trump's posts were retweets from friendly voices like his eldest son, Donald Trump Jr., and commentator Geraldo Rivera:

In his own tweets, Trump called the BuzzFeed report "disgraceful" and blamed it for a "very sad day for journalism."

Trump also tweeted on familiar topics including the Steele Dossier, the stock market, immigration, and his perceived persecution at the hands of the press. Bonnie Kristian

Saturday's third annual Women's March is expected to draw smaller crowds than in previous years thanks to accusations of anti-Semitism among national organizers.

Former Democratic National Committee chair Rep. Debbie Wasserman-Schultz (D-Fla.) formally withdrew her participation Friday, saying she "cannot associate with the national march's leaders and principles, which refuse to completely repudiate anti-Semitism and all forms of bigotry."

Other prominent speakers and sponsors from past years — including Sen. Kamala Harris (D-Calif.), Sen. Kirsten Gillibrand (D-N.Y.), the Democratic National Committee, the Southern Poverty Law Center, and NARAL — have cut ties as well. Most did not issue specific statements explaining their decision.

For those who do participate, events are organized in Washington, D.C., as well as hundreds of other cities nationwide and around the world. Policy focuses this year include the minimum wage, health care, and opposition to President Trump.

President Trump on Twitter Friday evening announced plans for a Saturday afternoon statement on his proposed border wall construction and the partial government shutdown:

Trump did not offer any further details on the nature of his announcement, nor did the White House press team respond to inquiries on the subject. "I'm not going to get ahead of the president, but I can assure he's going to continue fighting for border security. He's going to continue looking for the solution to end the humanitarian and national security crisis at the border," said White House Press Secretary Sarah Huckabee Sanders.

CNN reported Friday night an unnamed senior administration official said the president plans to offer a deal to congressional Democrats and will not at this point make an emergency declaration so he can use military funding for wall construction. Bonnie Kristian
