As if we needed any more evidence proving how tech-integrated the latest generation of e-bikes are, look no further than the OKAI EB50. The company has just released an over-the-air (OTA) update that lets users significantly increase the top speed limit of the bike.

Originally launched earlier this summer as the OKAI Ranger, the 1,000W fat tire OKAI EB50 electric bike arrived with a rather mundane top speed of 20 mph (32 km/h).

That kept the bike legally designated as a Class 2 e-bike in the US, meaning it had a throttle-operated top speed of no more than 20 mph, and could masquerade its 1,000W motor as a 750W continuous-rated motor to comply with the Class 2 e-bike limits.

But a recently released update to the OKAI smartphone app that pairs with the bike has given owners more than just a fancy new skin or rounder icons. This time the update came with serious performance increases.

The app provides the option to unlock the top speed to a higher 28 mph (45 km/h).

Interestingly though, OKAI itself has confirmed that users are actually seeing speeds as high as 31 mph (50 km/h) with a fully charged battery. Unlike many larger electric vehicles that regulate their voltage for smoother performance, most e-bikes power their motor controllers and thus motors directly from their pack voltage. That means higher motor RPMs are available at higher states of charge, with an e-bike’s top speed then slowly tapering down as the battery discharges.

The new update also appears to unlock that new high speed on throttle-only operation, meaning that riders don’t need to pedal as well to engage speeds above 20 mph. Generally speaking, Class 3 e-bikes require pedal assist to engage motor power between 20-28 mph. An e-bike that can hit the Class 3 top speed limit of 28 mph but on throttle-only isn’t technically considered Class 3 eligible anymore.

This could have regulatory implications that see the $1,999 OKAI EB50 e-bike falling outside of the three designated e-bike classes that are adopted in much of the US. In practice, most police departments don’t yet understand the nuance of e-bike classes and thus aren’t out there patrolling for e-bikes that look like they’re going slightly over 20 mph without pedaling.

Even so, slipping outside of designated e-bike regulations is a dangerous game to play, as it could subject such e-bikes to motor vehicles laws that the three class e-bike system is designed to exempt them from.

The OKAI EB50 electric bike’s extensive app — complete with OTA updates to adjust the bike’s performance — isn’t the only tech-centric feature on the bike. The EB50 also comes with an NFC-enabled key card to give riders a secure way to lock and unlock the e-bike, though the app can also be used to unlock the e-bike over Bluetooth to avoid carrying a key card.

Many e-bike companies are doubling down on feature-rich apps and other tech-focused features as a way to differentiate their products from competitors. This is especially true of companies that rely largely on OEM components that are found on dozens of other e-bike models. Hardware innovations are often much more expensive and labor intensive to innovate, but software innovations may only require a few computer science interns and bargain basement wages.

Could OKAI’s move be a sign of what’s to come in the industry? Will there be more common performance unlocks available as simple and easy downloads? Or will e-bike companies go the way of Zero Motorcycles and offer upgrades as downloadable content to be purchased in the future? Let’s hear your thoughts in the comments section below.

Affordably carry cargo with Heybike’s single or dual-battery Hauler e-bike starting from a $999 low

As part of its Prime Day e-bike Sale, Heybike is offering its Hauler Cargo Single-Battery e-bike at $999 shipped, while the dual-battery counterpart is down at $1,399 shipped. You’d normally shell out $1,499 and $1,899 for these two setups at full price, though discounts regularly bring things down to $1,199 and $1,599, which we have seen go lower a few select times in 2025. Only once before have we seen these two low prices appear, back during the brand’s Memorial Day Sale, with you getting another chance at the $500 savings here today.

Heybike’s Hauler e-bike comes as an affordable means to transport precious cargo, with the 750W brushless geared hub motor peaking at up to 1,400W to tackle inclines and for better pick-up when you’ve got packages, groceries, and more on board. It can max out at 28 MPH speeds in states where it’s allowed, and comes with the two battery options that largely depend on how much travel time you need, with the solo-battery setup giving you up to 55 miles of pedal assisted support and the dual-battery setup increasing that travel range up to 85 miles.

Not only are you getting another chance at the biggest savings and the best price here, but you’re doing so while also getting the means for sectional home backup support.

It comes with three primary means to recharge: plugged into a standard outlet, through your car’s auxiliary port, or by connecting up to a maximum 1,600W solar input. The included transfer switch gives you sectional backup support of up to six circuits in your home or on an RV, with it pre-wired for easier installation.

You can also pick up the brand’s DELTA 3 Portable Power Station with a free protective bag at $529 shipped, down from its usual $778 pricing. This is a smaller and more affordable backup option that has a 1,024Wh LiFePo4 capacity and can be expanded up to 5,120Wh with various expansion batteries from across the DELTA ecosystem. It provides 1,800W output, surging to 2,200W when needed, and has 13 total output ports to use for connections to devices and appliances.

With the battery included here, you can get up to 8 hours of wireless cooling/heating in your tent, car, or anywhere else you’re settling down.

Worx Nitro 20V 8-inch Cordless Pole Chainsaw

Get 13.3 feet of reach with Worx’s telescoping Nitro 20V 8-inch cordless pole chainsaw at $119 annual low

Amazon is offering the best pricing of the last year on the Worx Nitro 20V 8-inch Cordless Pole Chainsaw at $119 shipped. Normally, you’d have to shell out $170 for this tool at full price, which we’ve seen discounts taking as low as $120 once over the last 12 months, with prices otherwise keeping above $129. While it has gone lower in past years, you’re looking at the best price we have tracked since summer 2024, giving you $51 in savings off its going rate.

You’ll have plenty of reach to trim high branches with this Worx Nitro pole chainsaw, especially with the telescoping pole allowing for tool-free extensions up to 13.3 feet – plus, it weighs in at just 8 pounds, making it easy to manage and operate, despite varying operator sizes. The 8-inch bar and chain has three different cutting angles (0 degrees, 15 degrees, and 30 degrees) it can be set to, with the automatic oiler keeping things lubricated and running smoothly as you work. What’s more, your comfort has been taken into account with the 180-degree rotating rear handle, allowing you to easily switch between vertical and horizontal cutting positions.

EGO Power+ 56V 21-inch cordless electric lawn mower

Bring home EGO’s 56V 21-inch cordless electric mower with a 5.0Ah battery and rapid charger at $365

Amazon is offering the EGO Power+ 56V 21-inch Cordless Electric Lawn Mower with 5.0Ah battery and rapid charger at $364.60 shipped. This package would normally go for $430 at full price, which we’ve mostly seen it keeping at over the last 12 months, with few large price cuts on the books in that timeframe. While we have seen it go as low as $309 in the past, over the last 12 months, the rate we’re seeing today has only been beaten out by a short-lived drop to $350 back in April, with it otherwise being the best price we’ve spotted this year thanks to the $65 markdown.

You’ll get a much more budget-friendly means to tackle lawn care with this 56V 21-inch model over EGO’s higher-end mowers, giving you the torque of a gas engine without the noise and fumes. With the included 5.0Ah battery, the brushless motor will get up to 45 continuous minutes of runtime, while the rapid charger can have it back to full at much faster rates than a standard charger. There are six cutting height levels to adjust between (from 1.5 to 4 inches), as well as the versatility to side discharge, mulch, or collect clippings into the two-bushel bag. Not only does it come with an IPX4 weather-resistance construction, but it starts up at the push of a button and folds to a more compact size for easier storage options.

Arizona brings a huge grid battery online ahead of peak demand

One of Arizona’s biggest grid battery storage projects is now online and helping power homes as the summer heat ramps up.

Recurrent Energy, a subsidiary of Canadian Solar, just brought its 1,200 MWh Papago Storage facility in Maricopa County into commercial operation. The big grid battery is now supplying stored electricity to Arizona Public Service (APS), the state’s largest utility, in time for peak air-conditioning season.

Papago is the first of three Recurrent projects with APS. Together, they’ll provide 1,800 MWh of storage and 150 MW of solar power. That’s enough to run about 72,000 homes for four hours and provide year-round solar for another 24,000 homes.

“Summer is here, and we’re ready to serve APS customers with the energy they need when they need it,” said APS director of resource acquisition Derek Seaman.

The Arizona Corporation Commission chair, Kevin Thompson, noted that bringing online one of Arizona’s largest battery storage projects during a critical time when energy demand is skyrocketing is a milestone.

Canadian Solar’s e-STORAGE arm built the project and will keep it running under a long-term agreement.

Recurrent CEO Ismael Guerrero said, “We’re proud to deliver flexible capacity that meets the state’s growing energy needs and grateful for APS’s continued partnership.”

The Porsche Cayenne EV flexes its power towing 3-tons in public

Porsche promises the new electric SUV will “set new standards,” and it’s already proving it. Ahead of its upcoming launch, the Porsche Cayenne EV proved its might by towing a 100-year-old classic car and trailer weighing around 3 tons in public.

Porsche Cayenne EV flexes its performance in public

The Porsche Cayenne EV is already smashing records, and it’s not even out yet. Last month, a prototype beat every gas-powered SUV, setting a new SUV record at the Shelsley Walsh hill climb by more than four seconds.

Now, it’s at it again. Porsche showcased a near-production-ready Cayenne EV prototype in England for the first time as part of a public film shoot.

The camouflaged Cayenne EV showcased its impressive power by towing a 100-year-old classic car weighing over 2 tons. Including the trailer, the total weight was around 3 tons.

British TV presenter Richard Hammond took the Cayenne EV from his workshop in Hereford to his garage, towing the classic car behind.

According to Hammond, the electric SUV “handled it effortlessly,” adding, “We were trailing significant weight behind us, but you wouldn’t know it.”

Porsche designed the Cayenne EV and its high-voltage system, “to be one of the first BEVs in the world to achieve a towing capacity of up to 3.5 tonnes.” Depending on the configuration, it will be just as capable, if not more, than the current combustion-engine Cayenne.

As Michael Schätzle, Vice President of the Product Line Cayenne, explained, “That’s why we didn’t want to make any compromises in the development of the all-electric model.”

The Porsche Cayenne EV was initially set to launch this year, but it’s now expected to debut in production form later this year as a 2026 model. A “conspicuously camouflaged prototype” will be on display at the Goodwood Festival of Speed from July 10 to July 13.

More information, including prices and specifications, will be revealed closer to launch. However, we do know that it will be based on the PPE platform, the same one underpinning the Macan EV and the Audi Q6 e-Tron.

The Macan EV has an EPA-estimated range of 308 miles. On the European WLTP scale, it’s rated at 613 km (381 miles). However, Porsche said the platform will receive “comprehensive upgrades” for the Cayenne.
