Are you the kind of person that regularly has major demolition jobs that require a level of aggression and violence that hand tools simply can’t provide, but you also care about the environment and not destroying the only lifeboat humanity currently has? Then boy, do I have the perfect electric bulldozer for you.
Weighing in at 18,750 kg (or just over 41,000 freedom units), this big Bertha of an e-bulldozer is ready for some heavy lifting. Or make that heavy scraping.
Sure, it might weigh barely half of a D9 Caterpillar, but what it lacks in poundage it makes up for with a heart of gold. And lithium. It carries a 240 kWh battery on board for all day mess-you-up dozing needs. Well, not really “all day.” More like 4-5 hours of heavy-duty dozing and 6-8 hours of “medium to light working”, which I imagine is that category that terrorizing the neighborhood falls under.
That’s still a pretty big battery at around 4x the size found in an average electric car – or egregiously around 1x the size of the battery found in an electric HUMMER.
It carries a 145 kW (194 hp) electric motor, which frankly seems a bit underpowered for a bulldozer but I’m going to let it slide. Since this one is already half the weight of the really big boys, having half the horsepower isn’t that unreasonable. Considering that electric motors generally outperform diesel engines of comparable power ratings, this electric opposer dozer might just be packing some real oomph.
It’s not particularly fast with a top speed of just 10 km/h (6 mph), but it sure will look imposing at it slowly and silently rolls up on you.
The decibel rating is 76dB, which a conversion chart tells me is approximately equal to the noise of a vacuum cleaner. Somehow that’s not very helpful, and I’m just imagining this thing sounding like my knock-off Roomba as it mows down a shanty.
The Chinese vendor seems pretty proud of this thing, describing it as “the world’s first purely electric bulldozer.”
I’m not sure how true that is, with a few companies offering electric models, but I won’t hold their feet to the fire too hard if they’ll at least give me a test ride.
The only problem is I’d half to go halfway around the world to China to try it, or else fork over US $95,000 to buy my own.
Actually, that’s not a bad price at all. A D9 will run you over a million bucks, so this feels like highway robbery. Of course the customs and freight charges you’d have to pay would also feel like highway robbery, not to mention the very real chance that you might never even get the product. So I definitely don’t recommend trying to buy your own electric bulldozer on Alibaba. In fact, I recently got scammed buying my own electric mini-excavator on Alibaba (full story coming soon).
Suffice it to say that it’s probably not worth it to risk six figures (or less, in my unfortunate mini-excavator case) on a random Chinese electric heavy equipment purchase. But at least we can all enjoy daydreaming about having our own electric bulldozer. “What’s that, HOA? My lawn is slightly overgrown onto the sidewalk? How about I just move that sidewalk for you?”.
Oh, and for your viewing pleasure, I found a video of it in action. Volume warning though.

After years of waiting and many falsestarts, Formula E is finally going to debut its mid-race charging system, which will give cars a quick boost of energy charging at a rate much faster than current road cars can.
For years now, we’ve been hearing about FIA plans to introduce charging stops to electric racing.
In gas car racing, some series allow mid-race fueling and some don’t. The World Endurance Championship, which runs the 24 Hours of Le Mans, obviously needs to fill up several times during the race. But Formula 1, which hosts shorter races, eliminated mid-race fueling in 2010.
But the FIA already had one electric racing series, Formula E, which had debuted in 2014. At the time, each driver had two cars, and would swap mid-race to a fresh car with new batteries.
Battery-swapping had been considered, but it would be too complicated to set up at temporary race facilities in city downtown areas, as many Formula E tracks are.
Then, in 2018, Formula E debuted a new “Gen 2” car which had a big enough battery not to need a charge mid-race, and later a “Gen 3” car in 2022, which had much stronger regenerative braking, capable of 600kW of braking power. Gen 3 also has an “Attack Mode” feature that lets cars unlock additional power for a short period each race, adding to strategy and mixing up the race order.
The issues involved building the charging system in temporary facilities and ensuring safety of the system (and of pit stops in general, which is always a concern when cars are driving rapidly near people). But after winter testing prior to this season, Formula E now says the system is ready to go.
So, once again, Formula E is ready to announce that mid-race charging is definitely, totally, positively, 100% certain at the upcoming Jeddah E-Prix, on February 14-15 in Jeddah, Saudi Arabia.
Formula E thinks that proving this high-power charging technology could help road cars to charge more quickly, which could have myriad benefits for electric cars in general.
The series is calling the system “Pit Boost,” and it will consist of a 34-second pit stop that provides around 10% additional charge to the cars (about 4kWh). While 10% isn’t a lot, 34 seconds is also not a lot of time. For comparison, one of the fastest-charging cars out there, the Ioniq 5, can charge from 10-80% in 18 minutes, which means 10% charge takes 2.5 minutes – five times as long as Formula E cars will manage the feat.
The stop will be mandatory for all drivers to take at some point in the race, and will mean new strategy options for drivers. Taking the stop means getting more energy, which means that your car won’t have to do as much energy saving to get to the end of the race – but it also means giving up your position on track, which can be hard to get back if you do it late in the race.
However, we’ve never seen it happen before, so it will be interesting to see what kind of strategic options develop.
If you’re interested in seeing how it turns out, tune in to the Jeddah E-Prix on February 14-15 to see what happens. It’s a doubleheader race weekend, with night races both on Saturday and Sunday, February 14-15, at 5pm UTC, 9am PST, 12pm EST, and 8pm local time. You can check out how to watch the race in your area by going to Formula E’s “Ways to Watch” section. In the US, Roku should be the most reliable way to watch.

JackRabbit, the maker of pint-sized electric microbikes, is back with a new product designed to quickly recharge their batteries from pure, uncut photons mainlined into an e-bike directly from the sun. In true independent charging form, the Solar Charging Kit from JackRabbit keeps riders rolling even when there’s not a convenient AC outlet in sight.
Unveiled this week, the Solar Charging Kit consists of a single folding solar panel and a tiny voltage converter that is configured to output 42.0V, which is the exact voltage required by JackRabbit’s little e-bike batteries. There’s also an added USB-A and a USB-C charging port for powering other devices in addition to charging JackRabbit batteries.
“This Solar Charging Kit plugs directly into your bike,” explained the company, “letting you recharge without needing an outlet, but with a speed comparable to the charger that comes with the OG/OG2 (42V, 2A).”
That would mean the panel outputs around 80W of solar power, which the company says can recharge its batteries in just three hours. That fairly quick recharging speed is helped by the fact that JackRabbit’s batteries are a mere 151 Wh, or around a third of the size of most e-bike batteries.
If that sounds small, then you’re right – it is. But JackRabbit is all about going micro, offering barely 25 lb rideables that are easy to store and bring on adventures, even when they aren’t actually being ridden.
With small batteries that fit under the 160Wh limit for many airlines in the US, the batteries can be quickly charged and taken to the widest number of locations. And for riders that want to go further than a single 10-mile (16-km) battery will allow, extra batteries are small enough to fit a pants pocket. The company also offers much larger Rangebuster batteries, though they won’t pass by TSA and make it onto an airplane in your personal item.
It sounds like the Solar Chargking Kit should be able to charge up JackRabbit’s large RangeBuster batteries, though likely in more than three hours.
The $349 Solar Charging Kit is a bit pricier than building something similar yourself, but it’s also safer and more convenient than hacking together your own battery charger since it’s designed to work with JackRabbit’s batteries right out of the box.
Technically it’s only inteded for JackRabbit’s micro e-bikes (themselves technically seated scooters, even if they look and feel more like a typical bike), but it’d probably work for just about any 36V e-bike that requires 42.0V to charge.
This isn’t the first time we’ve seen solar charging kits for electric bikes, and it’s a trend that is certainly appreciated by outdoors and camping enthusiasts, festival goers, or anyone who finds themself and their bike spending extended periods in the great, sunny outdoors.
