Honda teases its first full-size e-motorcycle with fast charging

engadget.com Unknown 2025-10-09 23:51:17

Honda is preparing to announce its first electric motorcycle with fast charging, based on a new teaser video the company shared on Instagram. The video shows off the new e-motorcycle on test rides in Europe and teases the date, September 16, when Honda will presumably introduce it. Plans to expand Honda's lineup of electric motorcycles have been in the works since at least 2022, when the company announced it would release "10 or more" e-motorcycles by 2025.

Motorola Razr 2025 drops back to its all-time low price of $600

Ryan Haines / Android Authority Motorola Razr (2025) Foldable phones are still super cool little engineering feats. I still get pleasant conversations with random strangers when I use mine around town. The thing is, they have been pretty expensive until recently. The Motorola Razr 2025 is honestly the most affordable one that we would still recommend. It’s usually $699.99, but today the price is even better at $599.99, which happens to be the cheapest it has ever been. Buy the Motorola Razr 202

Motorola Razr Ultra 2025 deal: Is it better than the Samsung Galaxy Z Flip 7?

Ryan Haines / Android Authority The Samsung Galaxy Z Flip 7 may be getting more attention, but that doesn’t necessarily mean it’s your best flip phone option. Many will prefer the Motorola Razr Ultra 2025, especially at the current discounted price point. This offer puts both phones at the exact $1,099.99 cost, but the Motorola handset usually is $1,399.99, and many would argue it is actually a better phone.

TL;DR → The Spark Early Orion Nebula capture A few years back, I developed an interest in astrophotography thanks to YouTubers like Nebula Photos. Armed with an OM System OM-5 and a 15-140mm Olympus lens, I managed some decent shots of the Orion Nebula from a tripod by taking 300 pictures with a 2-second exposure time and stacking them in Siril. Knowing I could achieve better results with tracking, I bought a Move Shoot Move tracker for around €200. It delivered longer exposures, but finding

The best flip phones of 2025: Where does the Samsung Galaxy Z Flip 7 stand?

zdnet.com Kerry Wan 2025-11-11 06:15:16

Flip phones have come a long way in the last decade. After their resurgence with the 2019 Motorola Razr refresh, they have only improved over the years. The best flip phones not only have a big cover display and a strong hinge but also an intuitive software to utilize their unique designs. The 2025 Motorola Razr Ultra, for instance, packs an AMOLED foldable display, a feature-rich user interface and a comfortable in-hand feel, alongside a bunch of AI features.

Your Motorola phone has a secret way to make your PIN more secure. Here’s how to use it

androidauthority.com Unknown 2025-11-10 18:00:24

Joe Maring / Android Authority A secure Android phone is a healthy Android phone. If you’re like me, the primary line of defense for your phone is a PIN. Sure, you may also use your phone’s fingerprint sensor or face unlock, but it’s your PIN or password that’s ultimately keeping your data secure. PINs work the same on all Android phones: you enter the correct PIN to unlock your phone, and if you enter the wrong one multiple times, you’re temporarily locked out. And as we all know, the longer

Polestar sets production car record for longest drive on a single charge

arstechnica.com Unknown 2025-11-17 10:51:17

Ars recently reviewed the Polestar 3, the large electric SUV from the performance-oriented Volvo spinoff. There is a lot to like about the big Polestar, particularly the way it drives: sharp enough to give Porsche cause for concern. Among the handful of things I wasn't so keen on was its reluctance to drive slowly. Like a racehorse champing at the bit, the twin-motor Polestar 3 wanted to deliver lots of power with not much pedal travel, and it took a while, and some conscious effort, to adapt.

The case for commuting by motorcycle

arstechnica.com Unknown 2025-11-17 15:36:32

America has a motorcycle problem. Whereas the rest of the world views two-wheeled motorized transportation as transportation, the US sees motorcycles and scooters as toys. They're not something you use to commute to work or run errands. Instead, they're for riding to the coffee shop on weekends. This is a flawed line of thinking, and I'll tell you why, using two motorcycles as examples. But first, hear me out. I live in Los Angeles, which is famous for its hellacious traffic.
