Luna is selling a bike with specs that don’t seem to be possible. A 58-pound carbon-fiber full-suspension mountain bike with a Bafang M600 motor and a 48V 18.5Ah battery that somehow achieves 2.5kW of power. That makes it a recently marked down $4,000 mountain bike with light moto-like speed that can propel the bike past 30mph on flat dirt.

I’ve been riding the Luna X2 with the $350 Ludicrous option for almost a year now, and I’ve grown to love this thing, but with some important caveats…

Luna X2 Ludi

Luna sells some special bikes and motos, and the Ludi X2, which bridges the two, might be the best example of that. They took the Class 3 500W-rated Bafang M600 Motor that advertises 120Nm of torque and are pumping more than quadruple rated power through there, sometimes up to 2500W.

While there are some amazing advantages to this – notably, the incredible acceleration, even uphill – it also presents some problems. Obviously, that motor should be overheating, considering both the way more volt and amps than it is specced for. Luna is famous for hot-rodding Bafang motors, however, especially the M600, and they’ve done some really smart stuff here with heat dissipation with their bespoke controller. After a year of riding this thing, I can say it somehow works! Mostly.

Another problem is when you add pedaling to 2.5kW of power – all of a sudden, a mountain bike sprocket and chain rated for under 1kW of power are going to be pushed to their limits. I’ve already melted some sprockets by mistakenly changing gears up a steep hill on the Frey CC. I’ve been careful to avoid doing that on the X2 Ludi, but I still experience some slippage in high-torque situations. Unlike the Frey CC, where I’ve lost use of my second lowest sprocket, however, I’ve not done any damage in a year of riding the Luna X2, even up significant hills.

Speaking of going up hills, that unbelievable power will often pull the front wheel off the ground when climbing steep hills, presenting issues with steering and unintended wheelies.

Overheating

My first ride up our local 800-foot hill was going great at about 20-plus mph until about two-thirds the way up – I lost power and got an “Error 10.” I was able to power cycle the bike, and after a few minutes, I regained power. After rooting around in the forums, I found that the motor was overheating and shutting down.

Obviously, I can slow down to around 15mph and a lot less power and get a lot farther. But I wanted to understand exactly what was going on. Turns out, in steep hill climb situations, you want to keep your cadence very high to cool the motor and lessen the amps requirement. Most people that push this thing to the limit use the VESC tool running on an Android app to fine-tune this thing and keep it running optimally.

Luna uses the VESC app to tweak the Ludicrous controller, which is a paid download for $4 for Android or iOS, but I got an older version from Luna’s site. It allows you to pair to Luna’s controller and get almost real-time readouts of most of the vitals of the bike. The app isn’t terribly user-friendly to set up but is incredibly informative and great for keeping an eye on speed. You can then create different rider profiles to allow you to change your speed and power characteristics. I did find the readout to be a little small on rides, as someone that requires glasses for reading. I guess I need a bigger Android tablet!

In my case, the important readout is the bottom right motor heat sensor. When you start going up a hill at high power output, it will start rocketing upward. Once you are at 100 degrees C, you’ll hit the orange indicator, which is your signal to lay off the throttle and lower the pedal assist. Because the heat indicator is lagging by a few seconds, the motor is probably already closing in on its 120-degree cutoff, so you need to cut power immediately.

You can scale back to lowering heat by limiting the motor to its original 500W 120nm output. That is still plenty for hill climbing, just not at 20-plus mph. I find the bike operates quite well in the 80-100°C range.

On the other side of the spectrum, I wasn’t able to coax out even half the power on freezing cold days. That’s a shame because the bike’s Maxxis Minion tires are great for snow. After a few minutes of riding, the battery and controller do heat up, and the characteristics again go back to normal.

Once I learned my way around the heat factors, I could push this thing to its maximum.

For instance, I was able to easily climb Bromley Mountain’s 1,334 feet (407 m) in Vermont, which doesn’t have a bike lift or official bike riding path. I made it up the mountain with level 2 pedal assist without even coming close to overheating (myself or the bike!). At the same time, with the light frame and still powerful motor, I was still flying up the mountain to the point that it was actually fun to climb.

Because there is no lift and most mountain bikes don’t have this kind of power, I had the mountain to myself and was even able to find some off-the-beaten-path trails, which were tons of fun.

I was able to do four separate rides up the mountain before I needed to recharge, which I thought was pretty impressive. Luna knows their batteries, and even with driving Ludi with these chonky tires, I was seeing ranges over 20 miles. If I put smoother tires on here and ran on a road, I could see hitting 40 miles at 20mph.

Luna X2 specs

The Luna X2 is loaded up with some premium, if not top-shelf, components that would almost justify the $4000 price tag without a battery and motor:

  • Rockshox Debonair Yari 160mm front fork
  • Rockshox Deluxe Select+ 210mm x 55mm in rear 
  • Sram Eagle SX 12-speed cassette (standard HG driver, not the XD from SRAM)
  • Sram GUIDE 4 piston hydraulic brakes 200mm front 180mm back (6 bolts rotors)
  • Maxxis Minion 27.5×2.8-inch tires 
  • 44 56 non-integrated headset
  • Double wall alloy 40mm 27.5-inch rims
  • Dropper seat-post with internal routing
  • All cables throughout the bike are internally ran
  • Thru-axle hubs in both front and rear 15×110 Boost front, 12×148 Boost rear (length 180mm, 1.75 pitch)
  • 160mm front travel and 140mm rear travel
Luna X-2 review

One little extra bonus on the Luna X2 is the Carbon Fiber frame paint job. You’ll notice we’ve got the metal flake galaxy paint job, or as my wife likes to call it, “your glitter bike.” No shame here – I love the look of this thing.

In fact, to the untrained eye, the X2 looks a lot like an acoustic mountain bike. The 820Wh (48v 17.5Ah LG) battery is well hidden in the downtube, and the Bafang M600 motor or its heat sink only peeks out a bit from behind the pedals.

However, for those who know, the big “Luna” logo is what is going to be the big tell. Luna has long been outfitting electric bikes that pay more attention to what is possible than what is technically legal. Nowhere is that more apparent than the X2, which is described on Luna’s site:

This bike features our brand new Luna Controller the Ludi v2 which is a game changer. This controller will put out up to 60 battery Amps (2500 watts) As most Luna fans know, Luna has been hot-rodding Bafang motors for years with great success and this controller is sporting the heritage from our mighty BBSHD v2 controller. The Ludi v2 is 72V-rated controller which makes it extremely reliable at 48V and balances the user-adjustable buttery smooth pedal assist with the raw torque of 100 phase Amps readily available at the throttle. It even spins faster than any other M600 thanks to the Field Weakening and smoothly protects the motor from thermal overloads.

The X-2 comes in three sizes:

Electrek’s Take

The Luna X2 is truly a ludicrous mountain bike. It is a relatively light carbon fiber mountain bike that can hang with the more expensive bike shop brands, like Specialized Turbo Levo and Trek E-Caliber and, in many cases, has better components.

Where the Ludi X-2 really shines is the drivetrain. Having 2.5 kW of power at your disposal, even if just for short bursts, is like temporarily turning your mountain bike into a Talaria/Sur Ron and screaming across dirt roads at 30+mph. Having that power on a light mountain bike frame just doesn’t seem real.

Because of its high speed, I even found myself taking the X2 on my daily coffee shop commute if I was in a rush or wanted to blast up our big local hill.

The noted downsides of high power stress on the chain and sprockets as well as the overheating can be mitigated with some care and learning the bike. Luna has recently dropped the price of the X2, which can now be had for under $4K with an additional add-on for the Ludi controller.

Overall, this feels like the hot rod of mountain bikes, and I’m here for it.

An energy star inside U.S. homes is under attack from Trump, with the cost to homeowners uncertain

An energy star inside U.S. homes is under attack from Trump, with the cost to homeowners uncertain

Donald Trump, as both a citizen and president, has railed against modern dishwashers, washing machines, light bulbs, showerheads and toilets, claiming that onerous government regulations render them less effective and more expensive.

Since returning to the White House in January, he’s turned his ire into an edict.

On April 9, Trump issued an executive order directing certain federal agencies “to incorporate a sunset provision” into a laundry list of regulations governing energy production, including those covering appliances. A month later, he issued a memorandum, entitled “Rescission of Useless Water Pressure Standards.”

Following that, on May 12, the Department of Energy announced that it was preparing to eliminate or modify 47 federal regulations “that are driving up costs and lowering quality of life for the American people.”

Many of the rules are covered in the Energy Policy and Conservation Act (EPCA), a decades-old law that mandates energy-efficiency and water-conservation standards for home appliances and plumbing fixtures.

Meanwhile, the Environmental Protection Agency said it is planning to eliminate the Energy Star program, a popular voluntary initiative that manufacturers employ to rank their appliances based on energy conservation and cost savings, displayed on familiar blue labeling at retail as comparison-shopping guides.

Trump’s actions have been met with a mix of resistance from consumer protection groups and appliance manufacturers, as well as support from deregulation hawks and decriers of the nanny state. And while the administration continues to review the current standards and solicit comments before considering any official changes, legal challenges to the efforts are being weighed.

A new era of ‘buyer beware’ in electric bills

Originally passed in 1975, EPCA ensures that the entire array of products covered by the law all meet a basic level of energy- and water-efficiency performance, reflected in different price points. A prime example are the ubiquitous yellow Energy Guide stickers affixed to appliances that indicate their annual energy usage and cost. “Consumers who are shopping primarily, if not exclusively, on price also get reasonable efficiency performance [information],” said Andrew deLaski, executive director of the Appliance Standards Awareness Project, a coalition of environmental and consumer groups, utilities and state governments, based at the American Council for an Energy-Efficient Economy, a nonprofit research organization.

Without that level of regulated consumer protection, deLaski said, “It’s buyer beware.”

Consumers would face the risk of less-efficient appliances entering an unregulated marketplace, he said, “and you’re not going to know it until you get the [higher] electric bill.”

Separate from EPCA, the Energy Star labeling program was established by the EPA in 1992 as a public-private partnership. Managed and jointly funded by the DOE, it sets energy-efficiency standards that manufacturers can choose to display on appliances, building products, electronics, lighting fixtures, HVAC equipment and other products as a way for consumers and businesses to make informed purchase decisions.

The EPA estimates that 90% of households recognize the Energy Star label and that over its 33 years, the program has saved five trillion kilowatt-hours of electricity, reduced greenhouse gas emissions by four billion metric tons and saved $500 billion in utility costs. The program’s 2024 operating budget was $35.7 million. To date, every dollar spent has resulted in nearly $350 in energy cost savings.

Americans support energy-efficient appliance efforts

Consumer Reports conducted a national survey in March which found that 87% of respondents support energy-efficient home appliance standards. Nearly a third said that saving money on energy bills would motivate them to buy a more efficient large home appliance.

Last month, in response to plans to shutter Energy Star, the organization issued a statement urging the EPA to preserve the program. “The loss would hit especially hard at a time when people are dealing with unpredictable energy bills and trying to cut expenses,” said Shanika Whitehurst, associate director for Consumer Reports’ product sustainability, research and testing team.

The nonprofit Alliance to Save Energy, a bipartisan coalition of consumer, environment, business and government groups, suggests that EPCA and Energy Star actually promote the White House’s goals of lowering families’ energy bills and making the nation energy dominant. “If you start to dismantle the energy-efficiency programs, American households are going to pay for that,” said Jason Reott, ASE’s senior manager of policy. “Energy dominance begins at home, by eliminating energy waste.”

The Association of Home Appliance Manufacturers, which represents more than 150 manufacturers, has historically supported efficiency regulations, but pushed back against the Biden administration’s updates of EPCA standards for gas stoves, refrigerators, dishwashers and other appliances. The law requires the DOE to review standards at least once every six years, a process that has often led to rule changes.

“We have always been able to produce products at higher efficiency levels,” said Jill Notini, vice president of communications and marketing for AHAM, “but there’s a tipping point where you have to stop and say, you have to have the technology that allows those standard levels.”

“We very much appreciate the intent behind [President Trump’s] goals of deregulatory actions,” Notini said. “Our industry needs it after looking at our products and how far they have come in terms of energy efficiency and water use,” alluding to the eight rounds of EPCA reviews, updates and revisions over the years.

Already at or near peak efficiency, industry says

Today’s appliances are at or near their peak efficiency, a result of federal standards and manufacturers’ investment in technology and innovation, Notini said. “So there needs to be a recognition that we can’t stay on this path and continue to ratchet up standards and expect high-performing products,” she added.

AHAM favors revising EPCA standards, she said, based on technological advances rather than the every-six-year requirement. What the association does not endorse, however, is Trump’s request for the DOE to waive federal preemption of states’ regulations regarding the water efficiency of showerheads, faucets and toilets.

“It’s concerning to us that we may not have federal preemption, which creates that certainty that the industry is looking for,” Notini said, noting that several states have established their own efficiency standards on some EPCA-covered products. Federal preemption “truly is what has made energy efficiency such a success.”

AHAM member LG Electronics USA has mixed views on efforts to roll back EPCA, according to senior vice president John I. Taylor. “Generally deregulation is good for business, but there are some specific things in EPCA that are beneficial to American consumers and the American economy,” he said. “Our company has been a leader in driving energy efficiency, so regardless of how the regulations end up, we’ll continue to keep our foot on that accelerator.”

In March, nearly three dozen industry groups and appliance companies, including the Chamber of Commerce, Bosch, Carrier and the Air-Conditioning, Heating, & Refrigeration Institute (AHRI) sent a letter to EPA administrator Lee Zeldin, urging him not to end Energy Star. In April, the U.S. Green Building Council, along with more than 1,000 signatories — among them LG, Miele and Samsung Electronics America — wrote to Zeldin to express concerns about proposed cuts at the EPA, including Energy Star.

Energy Star very popular with consumers, according to retail sector

While major appliance retailers, such as Lowe’s, Home Depot and Best Buy, have not publicly commented on any of these pending regulatory changes, the National Retail Federation, one of several consumer products, manufacturing, real estate and retail organizations that sent a letter on June 6 to a bipartisan group of Congressional leaders, asking them to “strongly support continuation of the non-regulatory and non-partisan Energy Star program within the federal government.”

“Consumers have said overwhelmingly that they support voluntary environmental standard-setting programs like Energy Star,” said Scot Case, vice president of corporate social responsibility and sustainability and executive director for the NRF’s Center for Retail Sustainability. And that’s why retailers the trade group represents “want to make sure they’re able to share the benefits of those programs with the consumer,” he said.

Trump’s tribulations with energy-efficiency and water-conservation standards echo those of libertarians and free-marketers who maintain that regulations often represent government overreach and restrict personal choice. For instance, the libertarian Cato Institute has called Energy Star “a very coarse piece of energy information that may crowd out efforts” to develop more accurate ways to measure energy-operating costs.

“I’m a big proponent of energy efficiency, but I don’t think we need the federal government overriding the choices and preferences that consumers may have when purchasing an appliance,” said Nick Loris, vice president of public policy for C3 Solutions, a conservative energy think tank. He said rolling back EPCA standards is “a step forward in reducing government intervention into decisions that should be best left for producers and consumers.”

Where legal challenges are headed

As with a mounting number of actions taken by the Trump administration this year — from tariffs to immigration — tinkering with EPCA is expected to be challenged in federal courts. The law includes a so-called anti-backsliding provision, which prevents rolling back standards that have already been finalized. A 2004 case deLaski referred to, NRDC v. Abraham, upheld the provision. “Once a DOE standard has been updated and published in the Federal Register, you can’t go backward,” he said of the precedent.

The administration may seek legal authority to enact these deregulation orders by citing the “good cause” exception in the Administrative Procedures Act as a way to avoid the APA’s public notice-and-comment processes. Yet legal experts, environmental groups and state attorneys general have warned that skipping APA procedures — especially for weakening energy- and water-use standards covered by EPCA — would likely be deemed “arbitrary and capricious” and illegal.

Ultimately, considering the success and popularity of EPCA and Energy Star — with consumers, manufacturers and retailers — as well as the legal underpinnings, it’s entirely possible that both will remain intact, if perhaps with a few tweaks. “In one form or another,” Taylor said, “we expect both will.”

“We know consumers want the information, and the interesting thing about consumers is, they are also voters,” Case said.

CASE expands compact equipment lineup with new CX25EV electric excavator

CASE CE is expanding its mini excavator lineup with the launch of four models this week, including an all-new electric model designed to delivers emissions-free performance that rivals any of its comparably-sized diesel counterparts — including its CASE-branded siblings!

CASE calls the CX25EV a “highly versatile machine,” highlighting the excavator’s hydraulic flow settings and three auxiliary circuits that can be paired with a quick coupler and a variety of attachments. The mini excavator is also equipped with electrohydraulic controls that are fully customizable to the operator’s taste for speed, ramp-up speed and smoothness, while its short-radius design makes it easy to move around in tight, indoor spaces during trenching and precision demolition jobs.

The belief is that the new machine will enable construction crews to take on more challenging jobs that face unique noise, emission, or vibration requirements, the CX25EV electric mini excavator, originally announced last spring as part of a broader electric equipment launch, the new machine is now in production, on sale, and on its way to customers. Customers, it’s hoped, who will be able to keep operators happier and healthier without the loud diesel engines of the past.

And that is hugely important for the industry.

E-quipment highlight: Manitou telehandler gets electric retrofit

No matter how badly a fleet may want to electrify, harsh economic realities and the greater up-front costs typically associated with battery electric remain high hurdles to overcome — but a new retrofit option from French equipment manufacturer Manitou could help lower those barriers.

The retrofit solution showcased in the MT 1440 telehandler shown here was co-developed by Manitou Group and the electric engineers at Kinell for equipment rental group Kilotou as a cost-effective, energy-efficient way to decarbonize their customers’ construction and logistics operations. Crucially, this isn’t just a solution for late-model offerings — this MT 1440 telehandler is already seven years old!

“At a time when electric is set to become the norm and gradually replace fossil fuels, we see retrofitting as an alternative to mass replacement,” explains François Renault, Kiloutou director of equipment and sustainable development. “It is perfectly aligned with a comprehensive fleet upgrade program, without the need to buy everything back.”

Kinell’s modular retrofit replaces the 2018-spec diesel engine with a high-capacity battery sending power to a 55 kW (approx. 75 hp) electric motor. And, while battery specs aren’t shared, Kilotou says they expect a single charge to last a fully day in, “over 80% of daily usage cycles.”

Though it’s just a prototype for now, Manitou believes a retrofit solution like the one shown here could significantly reduce a job site’s carbon emissions — with all the safety and performance criteria equivalent to the internal combustion version. Once they get there, Manitou plans to offer the electrification kit, which would enable its customers to electrify without having to buy all new equipment assets.

“The goal (is to) provide an efficient solution for urban worksites, where reducing noise and emissions is critical, by converting diesel-powered telehandlers into electric models,” reads the official copy at Kinell. “The challenge was to develop a technically robust, economically viable, and scalable solution for converting diesel-powered telehandlers.”

Equipment World reports that the Kinell retrofits will be carried out on a number of equipment assets in the Kiloutou rental — each at least five years old. The repowered units will eventually be available for rent at Kiloutou’s branches in France, with retrofit packages eventually being rolled out to the larger market as the kinks are worked out.
