Yozma IN 10 Pro

This is a review of the Yozma IN 10 Pro, an electric dirt bike with a 2,500W motor and top speed of around 50mph, priced at just $1,899 at the time of writing.

This is a deviation from our usual e-bike reviews, and I want to highlight that in the eyes of the law, this is an electric motorcycle, not an electric bicycle, so it’s intended for off-road use on private land. Riding it on public roads or trails requires a license, insurance, and registration.

With that covered, let’s find out how the IN 10 Pro performed on the dirt.

Unboxing

The Yozma IN 10 Pro and its battery ship in separate boxes, which may arrive separately. Our test bike was well packaged and included a front light, footpegs, plastic covers, and a sling bag.

Assembly was more complicated than a typical e-bike. The front wheel, handlebar, fender, pegs, and rear shock need to be installed, but the manual covers each step clearly.

Yozma IN 10 Pro Specs

The IN 10 Pro is built on a one-size steel frame with a payload capacity of 330lb. Yozma says it weighs 143lb and fits riders from 4’7” to 6’3”.

The wheels (17” front, 14″ rear) wear dirt bike knobby tires. The suspension includes a non-adjustable inverted hydraulic fork and a nitrogen rear shock with preload adjustment.

The shock’s preload adjustment collar was very tight when it arrived, so I couldn’t adjust it with my hand. I got it moving with a hammer and punch, but I read that some owners used spanners. After oiling the threads I could move the collar by hand.

Power comes from a standard mid-mounted brushless motor driving a chain, with an 11t front sprocket and a big 60t rear cog.

On Yozma’s own website, the IN 10 Pro’s peak power is listed as both 4,500 and 5,500W, and top speed is reported as 47mph or 50mph. So I asked for clarification, and they confirmed that the motor has a nominal output of 2,500W and a peak output of 5,500W.

The FarDriver controller can be tuned through an optional Bluetooth dongle. The 60V, 27Ah (1,620Wh) battery comes with a 5A charger that provides a full charge in around 7 hours.

Yozma says the Canadian version of the IN 10 Pro comes with a factory speed limitation. Riders need to remove the limitation before accessing the full performance. The US version does not have this factory limitation and can deliver its full performance out of the box. True to this statment our test bike arrived locked at 20mph. To unlock it, hold the minus button for five seconds. When unlocked, the top speeds of the three ride modes are around 22, 34, and 47mph.

In the settings, there is an option to choose five or nine power modes. Users can also set the bike to power up so that the throttle doesn’t deliver power until a mode is selected, a handy safety feature.

The hydraulic brakes include a 220mm front rotor and 180mm rear rotor. These brakes use DOT brake fluid and are set up the reverse of a regular bicycle, with the right lever controlling the front brake and the left lever controlling the rear.

Yozma also provides a front light, a rear light with brake activation, fenders, and a single-sided kickstand with the IN 10 Pro.

Riding the Yozma IN 10 Pro

The IN 10 Pro looks, feels, and sounds like a dirt bike. The chain runs over a rubber slider and roller like a real moto, and the result is a mechanical hum that builds with speed. This noise is louder than I expected, but it’s not bad.

I found Power mode 1 measured and gentle, but Mode 3 was torquey enough to set me back in the seat and lift the front wheel. I hit 20mph from a stop in 3.5 seconds, and my GPS topped out at 47.9mph after I unlocked the top speed, just short of Yozma’s claimed top speed of 50mph. My display reads 1 to 2mph above my external GPS, but some testers report a 6mph difference.

The IN 10 Pro felt planted and comfortable cruising in the 30s, but past 40mph, the front end started to wander and bob, so I only took it to the top speed on wide, straight sections of smoother terrain.

Climbing is where the IN 10 Pro shines, at least in comparison to the e-bikes I usually test. Again, this is the first electric dirt bike I’ve tested, but it posted the fastest time on our gradual climb, averaging 37.3mph; one second faster than the dual-motor Eahora Romeo Ultra 2.

On the steep climb, it was the second fastest, just one second slower than the Romeo Ultra, and that e-bike is nearly twice the price. The only place where the bike struggled was up steep gradients on deep sand, which is full-size dirt bike territory.

I put the IN 10 Pro through our usual brake test, stopping from 20mph, and it stopped in 15.5 feet, which is a solid result. That said, most people will ride this bike at much higher speeds, and in my experience the brakes work well at these speeds, with plenty of modulation and no noticeable fade on steep downhills.

As usual, I performed a range test at max power output (mode 3) with the full speed unlocked. During the test, I made lots of full-throttle accelerations and tackled varied off-road terrains, and the battery lasted 28.08 miles with 1,472 feet of elevation gain at an average of 18.1mph. Yozma claims up to 60 miles, and while I couldn’t confirm that, a lighter rider cruising in low mode would probably get close to that.

On rough, rocky trails, the bike clunked and rattled under my 200lb, and I felt like I was pushing its limits. However, when another lighter rider rode it on the same trails, they found it much quieter. Another thing that annoyed me was that my heel rubbed the kickstand, but I wear a size-13 shoe, so take that into consideration.

None of this stopped me from riding where I wanted while testing the bike. I had a great time riding it on a variety of lighter trails, gravel, and dirt roads.

That said, the IN 10 Pro is clearly designed for a smaller, lighter rider despite the 330lb payload capacity, and I can’t speak to its durability after my short testing period.

Conclusion

So, is the Yozma IN 10 Pro worth $1,899?

If it’s treated as the entry-level pit bike, then yes, but just be aware that the low price brings a greater risk of experiencing quality control issues, and don’t expect this bike to compete with larger, more expensive alternatives in terms of performance.

Additionally, Yozma is a newer brand, so there’s little information available about long-term support, and the one-year warranty only covers manufacturing defects and replacement parts.

With my 200lb on board, the bike reached 47.9mph, demonstrated some of the quickest climbing I’ve recorded, and offered impressive braking performance.

I wouldn’t recommend this bike for adults of my size, but for younger or smaller riders who want a relatively gentle dirt bike to learn on before upgrading to a proper dirt bike, the IN 10 Pro delivers good value for money.

If you’re an adult looking for a high-performance ripper, this isn’t your bike. But if you’re shopping for a young rider and you want something that looks legit, rides predictably… it’s hard to ignore what Yozma is offering here.

The Yozma [IN 10 Pro] delivers strong power off the line and has no problem lifting the front wheel…. and the included Fardriver controller gives experienced riders plenty of room to tune the bike.

I think the bike feels great right out of the box. It feels good at speed… And the suspension feels great along with the large seat, which is very comfortable.

So, I love Yozma as a brand, but I think XPro takes it today because it’s just so much cheaper… I just think in terms of raw performance, the XPro offers so much more.

For being a completely stock bike, I think the IN 10 Pro does pretty good off-road, especially for being such a small pit bike.

You’re going to get about 20 miles of range is what I’d expect. And that’s a super realistic range. So, for the price and everything, I think this bike is super solid.
