Envo Stax is a $2,000 almost-perfect e-bike that looks like a regular bike
Today, we take a first look at the Envo Stax, a $2,000 almost-perfect e-bike that looks like a regular bike. It might have just become my new favorite electric bike.
I know that Micah generally does our e-bike reviews, as he should, he is the GOAT of e-bike reviewers after all. But I really wanted to do this one because when I first heard about the Stax, I felt like it was my perfect next bike.
For a quick background on my e-bike experience, I love them. I think e-bikes should take over a much larger market share of the overall mileage. I know it is doing just that for my own mileage.
Every time I can grab one of my e-bikes rather than my car, I do. It turns my travel into a fun activity. Obviously, regular bikes are great for that too, but e-bikes increase the opportunities by helping you find a balance between working out and covering distances.
You can also get to your destination using a stronger pedal assist and come back home without – or with less assist – to get a workout. It just offers some great opportunities like that.
My main e-bike has been the RadPower Radrover 6 Plus. It’s a great e-bike, and I love it, but it didn’t exactly match my needs.
With the power, front suspension, and fat tires, it is perfect for off-roading and that’s why I bought it. There’s a national park near where I live, and it is great to ride on the trails and dirt roads there.
But in practice, I found myself riding this bike on roads and bike paths about 90% of the time. And while the experience is still good there, it is not where the bike shines.
When I ride e-bikes, I like to find a balance between working out and using pedal assist. It is doable with the Radrover, but it is more difficult because of the weight and inefficiency of the fat tires.
So I started thinking about having a new daily rider that is more suited for road biking.
Enter the Envo Stax.
When I first learned about the Stax, I felt it might be the solution to my little problem.
First off, it looks great. You almost can’t tell that it is an electric bike. It is equipped with Envo’s own 500w motor that almost disappears behind the transmission system and brakes:
It can bring the speed of the Stax up to 32 km/h (20 mph) to fit most North American standards, but you can play in the settings of the beautiful color display if you want to change that – wink, wink.
As for the range, Envo is talking about 100 km or 62 miles range on the pedal assist level 1 (out of 5).
In my experience, that should be achievable and unlike many other e-bikes, the Stax feels great on level 1, or even without pedal assist, because it is so efficient.
My riding experience has been flawless so far with the Stax. I was able to set it up for a very comfortable riding position and customized the handle for effortless access to changing gear, pedal assist level, or pressing the optional throttle.
Where the Stax shines is its weight, which comes at just 42 lbs or 19 kg. It is very light for an e-bike, making it as usable as a regular bike without pedal assist.
It’s also useful to carry the bike around when you need to, like up the stairs if you live in a condo or apartment.
The only complaint I have about the Stax is its charge port. One of the reasons they managed to make it look like a normal non-electric bike is by seamlessly hiding the battery pack inside the the seat post.
The integration of the pack in the seat post is beautiful, but it limits the places where you can put the charge port. They decided to go with the top the seat post, which means that you have to manage to fit the connector between the post and the bike seat.
As for the price, it is a mid-range bike. It costs $1,999 in the US and $2,499 in Canada.
It is not the cheapest e-bike in this category, but I think it has the best value due to its form factor, weight, and efficiency.

After years of waiting and many false starts, 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.
Plans to bring mid-race charging to Formula E started in 2021, when the FIA started kicking around plans for an Electric GT racing series with 700kW charging.
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.
That 600kW charging ability could also be used for mid-race charging, so Formula E said that it was working on a system to allow for this. It announced that mid-race charging would come at some point in the 2023 season, but then pushed back those plans until 2024, and pushed them back again, this time with an uncertain date.
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.
