Onsra Challenger Review (Riding Breakdown)

By Billy | Updated: September 16, 2021 | Electric Skateboards

For the past five months I’ve been shredding the Onsra Challenger (belt-drive).

I’d still consider myself early in my electric skateboarding journey, so don’t expect technicals.

I’m working on learning about battery/motor specs, but for now, I’ll just share my riding experience.

Onsra sent this board to us for free. We only accepted it under the terms that we can share our honest thoughts and they agreed. Always wanna keep it transparent with you guys.

Direct Drive or Belt Drive?

So I decided on the belt drive because I’ve never experienced one before. My last electric purchase was the Shark Wheels electric and it had hub motors. Not to mention… the challenger is almost double the price.

The overall power of this board is pretty wild compared to what I’ve tried in the past. Riding it is super fun, but since it’s so powerful, it can definitely get sketchy, especially paired with double kingpins.

The protective cage around the motors makes it harder to kick the board up off the ground compared to a direct drive. You can do it though, and I don’t think it’s a big deal because it’s not like you’re going to be snapping the kicktail up since it’s so heavy.

Although the benefit of the cage is you can grab it and roll the board, so you don’t have to pick it up to carry. Because this thing is heavy, it weighs almost 22 pounds.

It was also a nice experience for me to figure out swapping out wheels and belts. Something that was completely new to me and it honestly took me a bit to figure out that I needed new belts, adjusting the gear ratio.

It’s a whole new world for me, but I’m loving it.

Parts Breakdown

The first thing I want to do is a parts breakdown, where I’ll share things I like and dislike about each.


The remote is a Hobbywing ESC, which I believe is pretty much the standard for most boards at this level.

I really enjoy how it feels to use. It’s not jolty at all and the overall aesthetic feels premium. 


As you can tell, the deck has an extremely aggressive concave. The most concave I’ve ever seen on any type of skateboard. Personally, I enjoy it because it really locks you in when you’re carving at higher speeds.

Most of my rides average 7-10 miles and I never really feel foot fatigue. Although for my range test, I definitely felt it in my back foot, so that’s the downside of this aggressive concave.

I really like the all-black deck, although the paint pretty easily comes off. 

The foam griptape is a nice addition. Not only do I think the design of it is cool, but I think it feels nice while riding.

I love the fact that there’s a kicktail, since I’m used to riding boards with kicktails. Although using a kicktail on a 22-pound board definitely takes time to get used to and I wouldn’t say it’s super functional. It works, but it’s challenging.


The Challenger comes with 105mm Cloud Wheels, which reminds me a lot of the MBS all-terrain wheels. I mean, they’re pretty much identical if you have them side by side. I don’t ride in a super rough environment but parts also aren’t always smooth, so a large treaded wheel is nice to have.

As far as wheelbite goes, I only experienced it when I was going under 4mphs and I pushed the board to the absolute max. Originally I was bummed about this, but I don’t think it’s that big of a deal for two reasons… 

Also, I swapped the Cloudwheels out with the 85mm 77a Organgatang Caguamas and I enjoy riding them a lot more than the Cloud wheels for my riding preference. They’re a lot smoother and the benefit of smaller wheels is that it’s now impossible to get wheelbite.


The bearings are solid – nothing really stands out about them. I know this is more of a personal preference type thing, but I’d love for them to be built-in spacers.

Although, I’m not sure if separated spacers are the norm in the esk8 scene?


The trucks are 13” double kingpins, which is really nice for carving. At first I was confused about the double kingpins. But they can actually handle speed pretty well.

Definitely takes some time to get used to.

I will say that carving on these is really fun. My ideal riding is averaging 10-15mph and doing long drawn-out carves. It’s soo fun.


I’m gonna be completely honest, I’m still learning about the techy side of electric boards.

I did a lot of research and have a somewhat solid grasp of what it all means. Still, obviously, a lot to learn, but…

The battery is…

As far as I’m aware is on the larger side, especially for this type of board.

There seemed to be some controversy because they originally claimed it was 504 watt-hours, although they have since changed it on their website.

Honestly, since I’m not that technical, that really wouldn’t have bothered me, but I can see why people got annoyed from a transparency aspect. It’s nice to see them walking back on their original claim.

For this type of setup, I would have been completely fine with a smaller battery for an overall lighter build, but that’s just for my riding preference.

The charging cap looks and feels pretty cheap, but it does the job. Would’ve love for that to be a little more heavy-duty.

Range Test

I did a range test from 100 % to 10% averaging about 16.7mphs, riding it semi aggressively in a pretty hilly environment. Maxing out the speed on straightaways, but also doing a lot of slower carving.

I weigh 165lbs, the weather was 80 degrees Fahrenheit and I ended up getting right around 16.4 miles with it.

That’s what my remote said and I tracked it with my phone and got 16.2. I’d say it was pretty accurate, and overall I think it’s solid considering they claim 24 miles but I did this after having over 100 miles clocked.

My Battery Issue

I think it’s important to note that this was my second range test. The first one I did one of the battery sensors disconnected and my battery died around 15 miles.

I ended up having to solder the sensor back on and it works fine now, but that was a little concerning.

Onsra’s customer support handled it well, where they offered three different solutions.

I have mixed feelings about this because Onsra handled it well and offered every solution they could. Since there are many more parts to an electric skateboard, there are always going to be issues – so I don’t think it’s fair to hold this against them. If this becomes a recurring issue, then I’d obviously consider it a problem.

But then again it got me thinking like, shouldn’t there be a more secure way to hold down those battery sensors?


Overall, I really enjoy the Onsra Challenger belt drive. 

The mixture of the aggressive concave, double kingpins, and 12s2p battery is super fun. Out of all my electric setups, this is the one I use the most.

This is a company that I will absolutely buy from in the future, not only because I feel like they have quality parts, but they offer a 2-year warranty with a nearby service center that I could easily send it out to.

Yes, they’re on the pricier side, but I think there’s a market for them. Especially if they stand behind their product.

I hope you enjoyed my Onsra Challenger review.
