This clever kit turns bicycles into electric bikes using their disc brakes
We’ve seen plenty of electric bicycle conversion kits around these parts, but rarely is there one that strays as far from the pack as the Skarper. This novel e-bike kit sports a unique look and claims that it can convert just about any bicycle into an electric bike – as long as it uses a disc brake.
That’s because the Skarper e-bike kit actually drives the rear wheel via the disc brake.
There’s a 4 kg (8.8 lb) clip-on mount that houses the motor, battery, and electronics in a slick-looking unit that connects to the bike’s chainstay.
The motor engages the disc brake, but not how you might expect. It doesn’t touch the braking surface, but rather interfaces with another section of the disc closer to the hub. That’s why riders will have to swap on the Skarper disc rotor in place of their own. Other than a few extra grams and a different-looking disc rotor, the bike won’t really be affected when the kit isn’t attached.
With the drive unit removed, the bike theoretically works as it did when it was a traditional pedal bike. But with the drive unit snapped in place, suddenly pedaling the bike will unleash the motor’s power and give riders a boost.
That power is a bit limited, perhaps due to the company’s European roots. The UK-based team had to conform to Europe’s more restrictive electric bicycle laws, which resulted in the Skarper e-bike kit offering just 250W of power and a maximum assisted speed of 25 km/h (15.5 mph).
There’s also no throttle, meaning riders will need to spin those pedals to turn on the helper motor.
With 45 Nm of torque, the assist is likely modest and not overpowering. It will help level out a hill compared to riding without any assistance, but it won’t turn an arduous hill climb into a pleasure cruise.
But while it may not be overly powerful, the company says the kit still boasts an impressive range to the tune of 30-50 km (18-31 miles) depending on the selected power level.
Recharging takes 2.5 hours, though in a pinch they say a quick 30-minute charge will get you 10-15 km (6-9 miles) of range.
The Skarper electric bike conversion kit seems to be sold out, but the company says they’ll open a new round of pre-orders for the £1,295 (approximately US $1,650) soon for delivery in early 2024.
That price is fairly lofty when you consider that many light electric bikes with similar power levels and battery sizes are priced at half as much, but then again they don’t turn themselves back into pedal bicycles with the click of a button.

The all-electric luxury electric SUV is getting significantly cheaper. Lexus launched a new entry-level 2025 RZ trim with starting prices over $10,000 less than last year’s model. And you get just as much driving range.
2025 Lexus RZ electric SUV prices and driving range
Lexus launched its first dedicated EV last year, the RZ electric SUV. Starting at $55,175, the 2024 Lexus RZ 300e has a range of up to 266 miles.
The 2024 RZ 450e AWD, equipped with its dual-moto DIRECT4 system, has a range of up to 196 miles. Prices start at just under $60,000. Both models are offered in Premium or Luxury packages.
Lexus is drastically lowering prices for the 2025 model year. The 2025 Lexus RZ starts at $43,975, and that includes the $1,175 delivery fee.
At under $44,000, prices for the 2025 RZ start at over $10,000 less than last year’s model. The lower price tag comes as Lexus added a new entry-level RZ 300e FWD trim to the lineup.
The 2025 Lexus RZ 300e FWD still has an EPA-estimated 266-mile range (18″ wheels), so despite the lower price, it’s no loss from last year’s model. It’s powered by a 72.8 kWh battery pack from global leader CATL.
Lexus modified the subframe for the FWD model, replacing the rear eAxle from the AWD model. The result is a quieter, smoother drive.
Powered by a 71.4 kWh battery, the 2025 RZ 450e AWD has an EPA-estimated driving range of up to 220 miles (18″ wheels).
| 2025 Lexus RZ model | Starting Price* | EPA-estimated Driving Range |
| RZ 450e AWD | $48,675 | 220 miles |
| RZ 450e Premium AWD w/ 18″ Wheel | $52,875 | 220 miles |
| RZ 450e Premium AWD w/ 20″ Wheel | $54,115 | 196 miles |
| RZ 450e Luxury AWD | $58,605 | 220 miles |

You can also opt for the available 10″ head-up display (HUD), Mark Levinson Surround Sound System, and a host of safety features.
The flat platform provides a spacious interior with 37.52″ of rear legroom, nearly as much as the second row of a Ford Explorer (39″).

‘Political malpractice’ if Trump undoes climate-geared Biden projects, outgoing U.S. energy secretary says
U.S. Secretary of Energy Jennifer Granholm speaks to the media on day five at the UNFCCC COP29 Climate Conference on November 15, 2024 in Baku, Azerbaijan.

A potential decision by Donald Trump to walk back the Biden administration’s climate-geared projects would impact jobs in areas governed by the President-elect’s own party, outgoing U.S. Energy Secretary Jennifer Granholm told CNBC, urging consistency in Washington’s green transition policies.
Referencing the White House’s withdrawal from the Paris Agreement — a 2015 treaty in which nearly 200 governments made non-binding pledges to reduce greenhouse emissions — during Trump’s first mandate, Granholm said the U.S. pressed ahead with projects linked to the green transition that members of Congress wanted to undertake in their districts.
“We are now building all of these projects. We’re building batteries for electric vehicles, we’re building the vehicles, we’re building the offshore wind turbines, we’re building the solar panels. And all of those are factories. And those factories are in districts of members of Congress,” she told CNBC’s Dan Murphy on Friday at the COP29 U.N. climate conference held in Baku, Azerbaijan.
She estimated that 80% of the funding from U.S. President Joe Biden’s legacy bills — the Inflation Reduction Act and the Bipartisan Infrastructure Law — went to U.S. districts represented by Republican leadership.
“It would be political malpractice to undo those opportunities when people are just now getting hired,” she said, stressing benefits to the manufacturing sector and noting that the business community of the world’s largest economy and oil producer now wants a clear course from Washington on its climate policy.
“This isn’t about in [the Paris Agreement], out, shifting back and forth. Let’s have a consistent practice,” she said.
When asked for a response on Granholm’s comments, Karoline Leavitt, a spokeswoman for Trump’s transition team, said the president-elect will “deliver” on the promises he made on the campaign trail.
International focus has now shifted on the shape of the U.S.’ future role in global climate policy, as Trump prepares to take the helm at the White House for a second mandate in January, following a sweeping victory against Democrat candidate Kamala Harris. Trump — who has yet to announce his own pick to lead the U.S. Department of Energy — put hydrocarbons at the front and center of his campaigning agenda, pledging to “end Biden’s delays in federal drilling permits and leases that are needed to unleash American oil and natural gas production.”
The U.S. Energy Information Administration (EIA) in March said that the country already “produced more crude oil than any nation at any time” for the past six years to 2023, averaging a crude oil and condensate production of 12.9 million barrels per day that year — breaking the previous U.S. and global record of 12.3 million barrels per day recorded in 2019, during Trump’s first mandate.
Yet Granholm on Friday stressed that the clean transition is also “unleashed” and will take place regardless of who is leading the White House — and that ignoring climate change risks sacrificing Washington’s position as a frontrunner in the blooming decarbonization industry.
“Why would we take a second, a backseat to an economic competitor like China?” she asked. “They have an economic strategy, they want to be number one. So if we get out of the game, we’re just going to cede that territory all over again. It’s bad strategy for the United States and for workers and for communities across the country.”
As the world braces for the possibility of a second U.S. exit from the Paris Agreement, some climate activists note that the green transition has now gained a different global momentum than during Trump’s first turn at the White House:
“There is no denying that another Trump presidency will stall national efforts to tackle the climate crisis and protect the environment, but most U.S. state, local, and private sector leaders are committed to charging ahead,” Dan Lashof, U.S. director of the World Resources Institute, said in a Nov. 6 statement.
“Donald Trump heading back to the White House won’t be a death knell to the clean energy transition that has rapidly picked up pace these last four years.”
Granholm also identified potential support in Trump’s current entourage, which this week welcomed business tycoon Elon Musk as the president-elect’s choice to head a new Department of Government Efficiency, alongside conservative activist Vivek Ramaswamy:
“His right-hand man, Elon Musk, is somebody who has been strongly in favor of products that … address climate change. Obviously, he’s the founder of Tesla,” Granholm pointed out.
Musk’s environmental stance has come under question over the years, shifting from telling Rolling Stone magazine that “climate change is the biggest threat that humanity faces this century, except for AI” and backing carbon taxes to holding that the world needs hydrocarbon supplies as a bridge to renewable energy.
