- The stock 19/19 wheel size feels wonky. Tackling harder riding like big rocks or MX tracks would need a wheel upgrade – we suggest 21/19 with higher-quality hardware.
- 68% increase in power, up from 12.5kW to 21kW – almost incomparable.
- Top speed is around 59 mph, up 3 from the first generation, so all that new power is for low-speed torque.
- Official range is 71.5 miles. This is widely variable, but in our hands-on testing we’ve found it to be pretty close to our real-world results.
- Our team identified 5 upgrades to unlock the Gen 2’s full potential.
The Surron Ultra Bee HP is the newest, fastest, coolest electric dirt bike model released by Surron. It’s a big step from the previous Ultra Bee, and even has anti-Surron e-moto riders intrigued.
What is so special about this e-moto? Why the hype? And did you notice that the Surron Storm has strangely disappeared? Does this mean the Ultra Bee is now the fast replacement top bike from Surron?
So many questions, we need to find some answers. But the most important question – is the Surron Ultra Bee your next e-moto? Or as you’re reading this blog, does it make you think of searching for a different e-moto? Let’s find out.
Power and Performance
Before we get to the harder questions, let’s start with the easy stats to find out what the difference is between the HP, released late 2024, and the previous Ultra Bee bike.
I want you to check out the peak power output of the 2026 HP Ultra Bee model (starting in 2025) compared to the previous 2023 model of 12.5kW. That’s a big difference right there! This might be the reason why so many riders are suddenly noticing the Ultra Bee, and perhaps why the Storm Bee has been phased out. Interesting fact, when the Storm Bee was released, it had a peak power of 22.5kW, not far from the 21kW of the new Ultra Bee.
It’s not just the power output that has been changed, the HP version of the Ultra Bee features a brand-new motor with HairPin windings. For those who aren’t completely up with e-moto motor terminology, this basically means the way the motor is structured allows more efficiency and higher speeds.
This new generation technology is paired with a new controller, which has been developed and tuned by Surron to get the most out of the motor.
With a large selection of modes, there are almost endless choices of power options. These modes are Eco, Daily, Sports, Crawl, Reverse, and Turbo. Eco, Daily, and Sports self explanatory, but I like the addition of Crawl, which gives you just a little power to walk the bike. Think steep hills where you can’t get your balance to jump on and ride up, or walking your bike around the paddock at an event. Reverse is also a useful mode to get yourself out of precarious positions. The Turbo button gives you a short burst of additional power, because, well, why not!
Battery & Range
New to the 2026 model Ultra Bee is a 60Ah battery, increased from a 55Ah battery. This gives a little more capacity on the 74 Volt system. It has a fast charge time of 2.5 hours from 20% to 80%. For e-moto standards, this is a pretty fast charge time. Find an aftermarket higher-rated charger and you can drop this time down even more.
The Gen 2’s battery has many more temperature sensors and an upgraded BMS. This allows for a higher power load. The battery is also quickly swappable.
Check out the video we made here on some of the upgrades to make this change even faster:
Top speed for the Ultra Bee HP Gen 2 is around 59 mph, and it has a recorded range of 71.5 miles. Keep in mind that these numbers are variable. It depends on the terrain, the rider, the riding style, and more, but in our hands-on testing we’ve found these figures to be pretty close to the real-world results.
Chassis & Suspension
I think most of us could agree that the Surron Ultra Bee is a good looking bike. Surron has done well with the aesthetics. From a practical point of view, the way the seat flows over the battery is similar to my gas dirt bike. Instantly, this gives much more controllability as you can shift your weight right to the front without jamming anything between the battery lid… get the picture?
It has a claimed weight of 195 pounds, depending on the actual components each production line is created with. And the weight is balanced nicely from front to rear.
The forks have had an upgrade. With a usable travel of up to 9.4 inches and adjustments for both compression and rebound, the forks work well in just about any condition. We’ve even added these forks to other types of e-moto as we think they work so well.
However, where this e-moto could improve is the wheel set. From the factory, it has 19 inch wheels front and rear. This makes the geometry feel wonky, in our opinion. While it will work well for the majority of riders, if you want to take it on anything harder, rocks, MX tracks, or anything that requires more technical riding, a wheel upgrade will be advantageous.

It is about the wheel sizes on the E Ride Pro, but it’s similar in theory to the Ultra Bee.
Who needs an Ultra Bee?
The rider who spends weekends on a Surron Ultra Bee, especially the 21kW new Ultra Bee, is a rider who knows what they like. Big power, fast acceleration on a sturdy frame. It still has that flickable, nimble e-moto feel, but with a slightly different twist. It’s more planted. Not 450cc dirt bike planted, but somewhat in between.
Although with care, a beginner could ride the Surron Ultra Bee, it wouldn’t be my first recommendation unless you’re super careful with the throttle and start in the lowest power setting until you get a feel of your machine.
This bike is aimed at those who have been riding for a while, perhaps they’ve come from a dirt bike background. Perhaps this is the next step from the LBX.
The Ultra Bee, in its stock form, would hold up to a weekend at the MX track, a trail adventure through the woods, or even a sturdy commuting bike. It is also the perfect e-moto to mod. This bike could see you competing in some hardcore events with the right upgrades. If you saw the video I shared at the beginning of this article, you would have seen the upgrades we’ve done!
What mods do we recommend?
The first thing we would recommend, like always, is to get out and ride your Surron Ultra Bee. Get a feeling for it, then change one thing at a time. Although for most riders, the Ultra Bee doesn’t need any upgrades, this is what we would recommend for any rider who wants more from their bike:
1. Upgrade the wheels. Our choice would be a 21/19 setup with the tires that match the terrain you want to ride. This will give you more stability and less feeling of jack-knifing the front end.
2. Bar risers and handlebars that suit your body shape. This gives a better riding position, so it’s easier to control the bike.
3. Footpegs: Something that will give you big grip, again, so you feel like you’re well connected to the bike.
4. Bash plate to protect your motor: This is an upgrade that will save you money. If you like rocky areas or trails over logs, this is definitely needed.
5. Brakes: The brakes on the Ultra Bee are pretty good, but for those who ride hard, especially if you’ll be looking to upgrade the power, stopping power is just as important.
Should you upgrade the 2026 Ultra Bee?
Absolutely:
The Surron Ultra Bee is a favourite among our team. It has always been a good bike, but since the upgraded Ultra Bee has been released, it is now one of our top favs. The extra power means this bike is great as it is from stock, and will handle just about anything.
If you’re looking to upgrade from the previous Ultra Bee, or perhaps taking the jump from the LBX or similar, the Ultra Bee is an e-moto worth looking at.
No way:
I don’t like more power or better handling. I’m happy with what I have! And hey, 21kW is a lot of power. It’s more than enough for casual trail riding or non-competitive track events.
Surron Ultra Bee Alternatives
Back to being serious again, if you’re liking what you see about the Surron Ultra Bee, but would like to know a few alternatives, then here are a few suggestions:
E Ride Pro SR
The E Ride Pro is a really good alternative; you could say it is also in the high-performance category for mid-sized electric dirt bikes. It has a crazy output of 25kW, slightly lighter than the Ultra Bee, and it has a 19/18 wheel setup, which we think gives better handling. The price is also less than the Ultra Bee. Wins all around.
Arctic Leopard XE Pro
Another option to consider is the Arctic Leopard XE. This is a 20kW bike that is also in a similar category to the Ultra Bee. It has quality components, such as KKE 37mm inverted forks, DOT rated brakes on 220mm rotors, and many more cool features.
