AIMA Rocky Review | It’s Got Flash; How About Substance?

The Rocky packs a respectable 720Wh battery paired with a 750W motor. Its 3A charger can top it off in roughly five hours from empty. AIMA claims 30–65 miles of range, and in our testing, that estimate proved to be pretty accurate.

In our max power range test on our local bike path, the Rocky went 29.9 miles. Run again in min power, it reached 60.3 miles. We completed both tests using the torque sensor setting, which is the more efficient of the two sensor options.

I love when real-world results land close to what a brand claims, and these numbers are close enough that I’m happy to give AIMA credit here. This is the kind of range that will cover the needs of most riders, so there isn’t much to nitpick.

Looking at efficiency, you can see the more powerful nature of the system show up in the data. The watts-per-mile figure in our low power test was about average compared to similar bikes, while the high power run wasn’t quite as efficient as some other setups. That’s the tradeoff for punchier acceleration and stronger hill performance (more on that in a second).

Overall, the Rocky’s range makes sense for its intended use. I also like that you can charge the battery off the bike if needed, and the integration is clean—it doesn’t distract from the Rocky’s standout look and paint job.

Bafang makes a wide range of motors, but its higher-power systems—like the one AIMA spec’d on the Rocky—tend to be consistent hill climbers. The Rocky’s results back that up.

On our standard test hill, the Rocky climbed on throttle in 1:45, averaging 17.3 mph. When pedaling with the torque sensor, it improved slightly to 1:41 with a 17.9 mph average.

Both runs land in the top 10 of our database since we switched to this hill as our full-time test location—roughly 100 bikes ago.

Plenty of e-bikes advertise a 750W motor, but the Rocky’s 85Nm of torque and 1,200W peak output are stronger figures than what you typically see at this class and price. If you want an e-bike that can flatten hills without making it feel like a big event, the Rocky delivers.

There was a time when I felt like I was practically begging the industry to make hydraulic brakes the standard on e-bikes. AIMA might be pushing the next good trend, too: bigger rotors for better stopping power. They’ve committed to 203mm rotors across their lineup, and it’s genuinely one of my favorite things about their builds.

You can see the benefit in our data. The Rocky logged a 20’11” result in our brake test, which is a strong showing—about a foot better than our average.

The Tektro brakes themselves are steady and predictable, with good modulation. They’re also easy to service, and replacements are straightforward at just about any bike shop. And since this hybrid clearly has road-use intentions, I also appreciate that AIMA isn’t skimping on safety details like turn signals—the Rocky includes them, and that’s something we like to see.

Kudos again to AIMA for sticking with larger rotors. Even dragging the brakes down longer hills, I didn’t detect any fade. Give me the bigger diameter rotor all day.

Outside of two big caveats—you have to like the look, and it has to fit you properly—this is a really nice bike.

It tracks super straight, and the handling is phenomenal. AIMA is quickly becoming one of the more consistently good-feeling rides I’ve spent time on. And I’ll say it: the paint job is awesome. It reminds me of a custom car. It won’t be for everybody, but I’m impressed.

The touch points are solid and the component choices feel well thought out. The fork works well for road use, but it’s not something I’d get too crazy with off-road. Larger riders in particular will notice its entry-level softness, but for the Rocky’s intended “commuter first, light trail second” mission, it gets the job done.

I also like the included headlight, the two mounting points along the frame, and the display—it’s genuinely a nice unit.

App integration with Bafang is another bright spot. The turn-by-turn navigation is great, and I have a bit of a love/hate relationship with the phone notifications. I wish it would limit things to calls and texts, but it seems to pass along just about any notification your phone receives (too many, in my case). Still, I’d rather have the feature than not—especially if you don’t want to give up handlebar real estate to a phone mount.

Fit is the lingering issue. The single frame size will work for a lot of riders, but it squeezes out taller folks, or even riders with longer legs. For reference, my 32” inseam isn’t exactly extreme, and I still felt the ceiling. I’d love to see additional sizes offered, and a few rack accessories (or more included utility add-ons) would go a long way toward boosting the Rocky’s value as a true hybrid.

Overall, it’s hard to dislike the Rocky—as long as it fits you. It’s a great match for riders who love the off-road look, but know most of their time will be spent on pavement. And if you do dip a toe into dirt, it’ll handle mild off-road riding just fine.

Motor engagement is a strong point. I like how the system can be customized to match different rider preferences, and the display is genuinely one of my favorite parts of the experience. Also: more Shimano CUES on bikes, and more brands standardizing larger rotors, please. I like that AIMA is helping lead the charge on both.
