Bosch Kiox and SmartphoneHub hands-on: The sleek displays e-bikes deserve

This story is part of our continuing coverage of CES 2020, including tech and gadgets from the showroom floor.

Today’s best electric bikes are sleek machines with high-tech features like integrated batteries, alarm systems, and wireless app connectivity. Yet you’ll likely control the bike with a black-and-white LCD that looks like a 1980s alarm clock. If you’re lucky, it’ll be backlit.

That doesn’t match the desires of tech-savvy urban cyclists who buy ebikes. Bosch has a pair of solutions, one for rugged mountain biking, the other for everyday commuters. I put them through their paces during a press event held in Red Rock Canyon outside Las Vegas.

Kiox is a rugged onboard computer

Serious off-road bikers should look for Kiox, an onboard computer with a rectangular, full-color 1.9-inch display. The screen’s not large, but it’s bright, covered with Gorilla Glass, and has an anti-glare finish that ensures the display is easy to see even at high noon on a bright summer day.

The Kiox computer itself, including the display, is removable thanks to its magnet attachment system. This has two benefits. First, you can take the screen with you to guard against theft or vandalism. Second, the onboard computer can pop off on impact. That can save the screen by letting it get out of the way instead of taking the full force of a crash.

Like most onboard computers, the Kiox can display a wide variety of fitness data. It can also sync with Bluetooth-enabled heart rate monitors for accurate training data. Bluetooth connectivity can also be used to sync data with various apps.

Kiox isn’t new for CES 2020, but you likely haven’t used it yet. Few electric bikes in the U.S. offer it yet. It now has a Lock function, which deactivates the motor when the onboard computer is disconnected. There’s also now an ABS light for bikes with that feature.

While Bosch says Kiox is targeted at “sporty riders,” I think it’s great for everyone. The screen isn’t large, but it’s bright, sharp, and colorful. It’s also very easy to read. I rode a bike with Kiox on a sunny day in the Nevada desert, yet never had the slightest trouble reading the screen. In fact, it’s clearer than the black-and-white LCDs I’ve used.

Kiox is exactly what I’d like to see every e-bike come with, and a major leap beyond the lame black-and-white LCDs that are still so common on electric bikes. If you’re interested, you can find Kiox on select e-bikes from several companies including Electra and Riese & Müller (two brands I rode at the press event).

SmartphoneHub is an infotainment center for your bike

Cyclists have used phones as an onboard bike computer for a decade, but there’s plenty of problems with that setup. The smartphone is exposed to damage, the mounts aren’t always reliable, and leaving the screen on constantly will quickly drain a phone of battery.

The Bosch SmartphoneHub addresses those problems with a clamp that’s built into the handlebars. It provides a secure hold on the phone in landscape orientation. Plus, the SmartphoneHub has a USB port that can provide power to the phone, so you don’t have to worry about running out of battery life.

Bosch designed the Hub to work with the Cobi.Bike app which, once launched, does exactly what you’d hope an app for cyclists would. You can use it to view your riding stats, of course. But you can also use it for navigation, to call contacts, or view weather predictions.

I can’t heap enough praise on the app. It’s excellent. App issues have stopped my efforts to use a smartphone while biking in the past. No one app has ever bundled all my needs to my satisfaction, so I’d want to switch apps mid-ride. But switching apps while riding never felt safe.

That said, I think some riders here in the U.S. will be disappointed the app doesn’t come from a more well-known company. Cobi.Bike is big in Europe, I’m told, but I’ve never witnessed anyone use it in America. Luckily, the app can connect to other fitness services like Apple Health, Google Fit, and Strava.

The SmartphoneHub is meant to be used with your phone, but it also has a 1.52-inch black-and-white LCD. This screen sits beneath where you clamp the phone, so it’s only visible if you don’t connect it. This is the backup screen. If you don’t have your phone on you, the built-in LCD can display basic information like speed and range remaining.

SmartphoneHub is clever, but sign me up for Kiox

I tried the SmartphoneHub alongside Kiox during my 13-mile press ride. The Hub works like a charm. I’ve never had much luck using cycling apps to track my fitness data. They often prove finicky or inaccurate. The SmartphoneHub and the Cobi.Bike app suffered none of those problems. The app was fast, responsive, and easy to control. My effort was accurately portrayed in RPMs, watts, and calories burned because the app’s data comes directly from the bike.

And yet, I still preferred the Kiox. For all the Hub’s strengths, it couldn’t defeat a basic problem that exists on every phone. Glare. Placing a large smartphone screen between your handlebars is little better than strapping a mirror in front of you. The sunny Moab desert often made the smartphone display annoying to read, even at the display’s maximum brightness.

Kiox had none of those issues. The 1.9-inch screen was small, but it displayed everything I needed to know. I also like the smaller screen’s lack of distractions. The information I need is available at a glance, but the screen doesn’t dominate the space in front of me. I can concentrate on enjoying the ride.

Still, I’ll acknowledge the usefulness of SmartphoneHub. The navigation and contacts features seem great, and their usefulness will double if your phone is paired with exercise headphones or a smart helmet. You can see and hear turn-by-turn directions, just like a modern car’s infotainment system.

Kiox and SmartphoneHub are available now on select electric bikes. I’m hopeful more companies selling e-bikes in America will pick them up. They give e-bikes the modern, feature-packed displays they deserve.

Josh Gad had to explain the Star Wars sequels to Mel Brooks while pitching Space Balls 2
Luke Skywalker with a blue lightsaber at the climax of The Last Jedi.

Space Balls has long been one of Mel Brooks's most beloved films, in large part because it lovingly parodies the Star Wars universe. In fact, that film has become so beloved in and of itself that a sequel is in the works from actor Josh Gad, who co-wrote the sequel script with Dan Hernandez and Benji Samit.

In a recent interview on Let's Talk Off Camera with Kelly Ripa, Josh discussed development for the new film and explained that he had to do a lot of explaining for the 98-year-old comic legend. When Space Balls was released in 1987, the original trilogy was just a few years old, and in the years since, there have been eight new Star Wars movies that Gad had to walk through.

Gerard Butler says the live action How to Train Your Dragon is incredible

Live-action remakes of beloved animated classics are, it seems, inevitable, and a remake of How to Train Your Dragon is next in line. If you believe one of its stars, Gerard Butler, though, this one's actually going to be pretty good.

Of course, Butler is not the most unbiased source of information. He is reprising his role as Stoick in the new film, a character he voiced in the animated trilogy. In a recent interview with Entertainment Tonight, Butler talked about seeing the new film without effects and also said that it was a real struggle to go through costuming for the role.

This new RTX 5080 leak is starting to make me worry
Leaked packaging for Nvidia's RTX 5080.

The packaging for Nvidia's RTX 5080 was just leaked mere hours ahead of the official announcement of the RTX 50-series during CES 2025. The packaging confirms a couple of previous leaks, which is great -- but it's the early retail listing, spotted by VideoCardz, that's making me worry. The pricing implies that, unsurprisingly, one of Nvidia's best graphics cards might indeed be really expensive.

The initial leak comes from wxnod on X (Twitter). It shows us several boxes of the RTX 5080 stacked on top of each other. These aren't Nvidia's own Founders Edition designs, but custom designs made by one of Nvidia's partners, Gainward. Unfortunately, all the juicy specs are usually tucked away at the back of the box, which we don't get to see in this image. Still, the box does confirm 16GB of GDDR7 memory for the RTX 5080.
