Rawrr Mantis or Surron Ultra Bee: should you go with the default or the challenger?
The Surron Ultra Bee remains the safer default pick for most riders because of its established parts network and the sheer volume of owner knowledge available across forums and social groups — when something goes wrong, someone has almost certainly already solved it. The Rawrr Mantis is a genuine challenger with a specific selling point: per manufacturer and owner-reported figures, it's noticeably lighter than the Ultra Bee, which matters directly for riders who jump, do technical single-track, or simply want a bike that's easier to muscle around in tight terrain. Choose the Mantis if low weight and agility are your top priority and you're comfortable being an earlier adopter of a smaller brand; choose the Ultra Bee if you want the deepest support network available in the category today.
Weight: the Mantis's core selling point
Weight is where the Mantis differentiates itself most clearly. Lighter e-motos are easier to flick through switchbacks, easier to pick up after a tip-over, and generally less fatiguing over a long trail day — all reasons weight has become one of the most discussed specs in e-moto buying threads. Riders who've put time on both bikes consistently report that the Mantis's lower weight is noticeable within the first few minutes of riding, particularly in technical, low-speed terrain where a bike's mass fights you through direction changes.
The Ultra Bee isn't a heavy bike relative to a gas dirt bike, but within the e-moto class it carries more weight than the Mantis, largely a function of its larger battery and more robust suspension components built for its higher power ceiling. That extra mass isn't wasted, though — it's part of why the Ultra Bee holds a planted feel at higher speeds that some riders prefer over a lighter bike's twitchier handling.
Power and capability
The Ultra Bee is tuned toward a broader spread of capability — trail riding and light motocross use — with power output that most reviewers consider strong for its price tier. The Mantis, per Rawrr's own positioning, leans toward being a nimble, lighter-weight trail tool rather than a bike built to chase the top power numbers in the class. Neither bike is objectively underpowered; they're simply optimized for different tradeoffs between weight and raw output.
Parts and support: where Sur-Ron's head start still matters
This is the practical factor that tips the decision for a lot of buyers. Sur-Ron's multi-year head start in the U.S. market means Ultra Bee owners have an easier time finding replacement parts, accessories, and local shop support. Rawrr is a newer entrant, and while its community has grown quickly, per rider forum reports the parts and service network is still smaller and more regionally concentrated than Sur-Ron's. That's a real cost of being an early adopter — one worth weighing against the Mantis's weight advantage before buying. It's also worth understanding how e-moto street-legal rules vary by state before committing to either bike, since that classification issue applies to the Mantis exactly as it does to any Sur-Ron model.
Why a thin SERP for the Mantis doesn't mean thin demand
Search interest around the Rawrr Mantis is still comparatively low next to established names like Sur-Ron, but that's a function of how new the brand is to the U.S. market, not a signal about the bike's quality. Riders who've bought one after researching independently tend to cite the same reason: the weight difference is real and immediately noticeable, and for technical single-track or anyone who regularly picks a dropped bike back up off uneven ground, that's a tangible, daily benefit rather than a marketing claim. As the Mantis's owner base grows, expect its parts ecosystem and community knowledge base to close some of the gap with Sur-Ron over the next few seasons — but today, that gap is still real and worth planning around.
| Spec | Rawrr Mantis | Surron Ultra Bee |
|---|---|---|
| Weight | Lighter, per manufacturer/owner reports | Heavier, larger battery and suspension |
| Power focus | Agility-oriented | Broader power and trail/moto capability |
| Parts network | Smaller, growing | Established, deepest in class |
| Best for | Riders prioritizing low weight and agility | Riders prioritizing support and parts availability |
Pick the Mantis for class-leading agility and weight; pick the Ultra Bee for the deeper support network most owners still rely on.
Gear up for it
Whichever bike you choose, a couple of accessories matter regardless of weight or power differences. A MIPS-rated helmet such as the Check price on Amazon → is the first purchase after the bike itself. And because both the Mantis and Ultra Bee are commonly ridden on mixed terrain where tire choice matters, a trials-pattern tire like the Check price on Amazon → is a widely recommended upgrade for riders tackling rockier or more technical trails than either bike's stock tire is optimized for.
The bottom line
The Mantis's lighter weight is a real and noticeable advantage in technical terrain, but the Ultra Bee's parts and support network is still the deeper safety net for most buyers. Weigh how much agility is worth to you against how much you value an established ownership experience, and don't let novelty alone decide it — both bikes deserve a test ride before you commit either way.
