For the Valen Rev+, Retrospec managed to get the best out of that iconic moto-style scrambler spirit and put it into a comfortably handling fat tire e-bike while also keeping the performance bits that make it fun, and the best part is it comes at a reasonable price of just under $1,800
Aside from the looks and price this bike has a unique fun factor that comes from a combination of a few key components here.
One is the 20 by 4.0 inch Fat MTB tires with puncture protection and reflective sidewalls. Aside from these tires offering an extra layer of protection and suspension, Retrospec’s decision to offer wide tires also gives way more stability than a typical bike tire, which makes going through ruts, mud, or sand pretty effortless.
The second key component is the front suspension, which is fully adjustable and has 100mm of travel. Combined with the extra suspension from the fat tires, as mentioned earlier, this makes otherwise challenging terrain turn into fun detours that you’ll likely go out of your way to use.

The third component is the 750w rear hub motor, which gives the bike a 28 mph assisted top speed. Combined with the secure handling and added front suspension, the Valen Rev+ is the kind of bike you want to plan an adventure with. Whether that’s a dirt road shortcut on your commute or a day to the beach, the comfortable long seat makes it hard to say no to a trip with the Valen Rev+
On the practical side, Retrospec put some significant thought into the design and build of this bike to ensure that riders are cared for with those often less thought of yet still essential features. Starting with the battery, the fully integrated 720Wh battery uses LG 21700 cells for a total of 68 miles of range when fully charged. In addition, the battery is lockable and easily removable for both on- and off-bike battery charging. It’s also seamlessly integrated into the bike’s frame, making for a clean look.
For safety, Retrospec added Tektro hydraulic disc brakes with e-bike-specific rotors, which is an important upgrade, considering an improved rotor typically allows for better heat dissipation and better overall performance. There are also Integrated front and rear lights with 100 Lux illumination for the front. Safety aside, the design here for the front light looks amazing.
For the less thought-of yet essential features, Retrospec included an easy-change rear wheel removal system that uses braze-ons located at the lower part of the bike, so there’s no need to remove zip ties. Unlike other e-bikes, the Valen Rev+ kept it simple with the same axel nut for both the front and rear which means fewer tools, but what makes the process itself a lot easier is not having to wrestle the chain when re-installing the wheel thanks to the chain hanger.
One of the great feelings of the Retrospec Valen Rev+ e-bike is how simple yet stylish it is; the display is a center-mounted color display with controls on the left-hand side of the handlebars. The control panel has only three buttons, so it’s as simple as it gets. With the up or down control, you can change through 6 levels of pedal assist, but if you’re looking for more control, you can also use the controls on the right side of the handlebars to cycle through the eight speeds on the Shimano Altus derailleur.
For how comfortable the moto-inspired Valen Rev+ is, it also feels great to pedal on in case you’re looking for more exercise and want to opt for the pedal assist rather than the throttle only. Unlike other e-bikes on the market, Retrospec’s Rev+ makes riding very approachable. For those who are newer to riding, that long seat and wide tires add a level of stability, making the overall learning experience much more enjoyable. With how comfortable the bike rides, it might make you think more about leaving the car at home more often and opting for the bike paths.
For those looking to get as much fun as possible out of an e-bike aside from the fat tires and front suspension, Retrospec’s BMX style handlebars offer excellent geometry and height that gives you much more control over the bike in case you wanna stand up and tackle some of the more challenging trails. In addition, if you’re looking to forget pedaling altogether, you could even choose to get the optional footpeg accessories, which, combined with the BMX-styled handlebars, will make the bike much more functional for off-road riding.
Overall, Retrospec seems to have put a lot of effort into bringing that scrambler moto spirit into a comfortable bike with loads of features that other manufacturers haven’t quite nailed down. From the easy rear wheel removal to the BMX-styled handlebars and comfortable long seat, it’s a very approachable and easy-to-maintain e-bike that can still rip on trails for those who want to tackle more of that tough off-road terrain.

Japanese equipment giant Kubota brought 22 new or updated machines to the 2025 bauma expo earlier this year, but tucked away in the corners was a new retrofit kit that can help existing customers decarbonize more quickly, and more affordably.
The latest equipment maker to put its name on the retrofit list is Kubota, who says its kit can be installed by a trained dealer in a single day.
That’s right! By this time tomorrow, your diesel-powered Kubota KX019 or U27-4 excavator (shown) could be fitted with an 18 or 20 kWh li-ion battery pack and electric drive motors and ready to get to work in a low-noise or low-vibration work environment where emissions are a strict no-no. Think indoor precision demolition or historic archeological excavation.

Then, if necessary, it can go right back to diesel power.
Kubota says its modular retrofit kits is a response to the increasing global demand for sustainable alternatives by focusing on making machinery that’s flexible and repairable enough to be “reusable,” and offer construction fleet managers a longer operational lifespan, superior ROI (return on investment), and lower TCO (total cost of ownership) than the competition.
Kubota’s solution also notably reduces maintenance costs and operational overheads. With no engine and associated components, servicing time and expenses are considerably reduced, saving customers both time and money. Additionally, with electricity costing far less than fossil fuels, it offers a highly economical advantage.
International Rental News reports that other changes to the excavators include a more modern cab controls with a digital instrument cluster, a 60 mm wider undercarriage for more stability, and an independent travel circuit allows operators to use the boom, dipper, bucket, and auxiliary functions without an impact on tracking performance.
Kubota’s new kit, first shown at last year’s Hillhead exhibition in the UK, will officially be on sale this summer – any day now, in fact – though pricing has yet to be announced.

Solar and wind accounted for almost 96% of new US electrical generating capacity added in the first third of 2025. In April, solar provided 87% of new capacity, making it the 20th consecutive month solar has taken the lead, according to data belatedly posted on July 1 by the Federal Energy Regulatory Commission (FERC) and reviewed by the SUN DAY Campaign.
Solar’s new generating capacity in April 2025 and YTD
In its latest monthly “Energy Infrastructure Update” report (with data through April 30, 2025), FERC says 50 “units” of solar totaling 2,284 megawatts (MW) were placed into service in April, accounting for 86.7% of all new generating capacity added during the month.
In addition, the 9,451 MW of solar added during the first four months of 2025 was 77.7% of the new generation placed into service.
Solar has now been the largest source of new generating capacity added each month for 20 consecutive months, from September 2023 to April 2025.

Solar + wind were >95% of new capacity in 1st third of 2025
Between January and April 2025, new wind provided 2,183 MW of capacity additions, accounting for 18.0% of new additions in the first third.
In the same period, the combination of solar and wind was 95.7% of new capacity while natural gas (511 MW) provided just 4.2%; the remaining 0.1% came from oil (11 MW).
Solar + wind are >22% of US utility-scale generating capacity
The installed capacities of solar (11.0%) and wind (11.8%) are now each more than a tenth of the US total. Together, they make up almost one-fourth (22.8%) of the US’s total available installed utility-scale generating capacity.
Moreover, at least 25-30% of US solar capacity is in small-scale (e.g., rooftop) systems that are not reflected in FERC’s data. Including that additional solar capacity would bring the share provided by solar + wind to more than a quarter of the US total.
With the inclusion of hydropower (7.7%), biomass (1.1%), and geothermal (0.3%), renewables currently claim a 31.8% share of total US utility-scale generating capacity. If small-scale solar capacity is included, renewables are now about one-third of total US generating capacity.
Solar is on track to become No. 2 source of US generating capacity
FERC reports that net “high probability” additions of solar between May 2025 and April 2028 total 90,158 MW – an amount almost four times the forecast net “high probability” additions for wind (22,793 MW), the second-fastest growing resource. Notably, both three-year projections are higher than those provided just a month earlier.
FERC also foresees net growth for hydropower (596 MW) and geothermal (92 MW) but a decrease of 123 MW in biomass capacity.
Taken together, the net new “high probability” capacity additions by all renewable energy sources over the next three years – i.e., the bulk of the Trump administration’s remaining time in office – would total 113,516 MW.
FERC doesn’t include any nuclear capacity in its three-year forecast, while coal and oil are projected to contract by 24,373 MW and 1,915 MW, respectively. Natural gas capacity would expand by 5,730 MW.
Thus, adjusting for the different capacity factors of gas (59.7%), wind (34.3%), and utility-scale solar (23.4%), electricity generated by the projected new solar capacity to be added in the coming three years should be at least six times greater than that produced by the new natural gas capacity, while the electrical output by new wind capacity would be more than double that by gas.
If FERC’s current “high probability” additions materialize, by May 1, 2028, solar will account for one-sixth (16.6%) of US installed utility-scale generating capacity. Wind would provide an additional one-eighth (12.6%) of the total. That would make each greater than coal (12.2%) and substantially more than nuclear power or hydropower (7.3% and 7.2%, respectively).
In fact, assuming current growth rates continue, the installed capacity of utility-scale solar is likely to surpass that of either coal or wind within two years, placing solar in second place for installed generating capacity, behind only natural gas.
Renewables + small-scale solar may overtake natural gas within 3 years
The mix of all utility-scale (ie, >1 MW) renewables is now adding about two percentage points each year to its share of generating capacity. At that pace, by May 1, 2028, renewables would account for 37.7% of total available installed utility-scale generating capacity – rapidly approaching that of natural gas (40.1%). Solar and wind would constitute more than three-quarters of installed renewable energy capacity. If those trend lines continue, utility-scale renewable energy capacity should surpass that of natural gas in 2029 or sooner.
However, as noted, FERC’s data do not account for the capacity of small-scale solar systems. If that’s factored in, within three years, total US solar capacity could exceed 300 GW. In turn, the mix of all renewables would then be about 40% of total installed capacity while the share of natural gas would drop to about 38%.
Moreover, FERC reports that there may actually be as much as 224,426 MW of net new solar additions in the current three-year pipeline in addition to 69,530 MW of new wind, 9,072 MW of new hydropower, 202 MW of new geothermal, and 39 MW of new biomass. By contrast, net new natural gas capacity potentially in the three-year pipeline totals just 26,818 MW. Consequently, renewables’ share could be even greater by mid-spring 2028.
“The Trump Administration’s ‘Big, Beautiful Bill’ … poses a clear threat to solar and wind in the years to come,” noted the SUN DAY Campaign’s executive director, Ken Bossong. “Nonetheless, FERC’s latest data and forecasts suggest cleaner and lower-cost renewable energy sources may still dominate and surpass nuclear power, coal, and natural gas.”
