Zwift’s Big Spin 2026 kicks off today, and with it the much-loved prize spinner! This year’s big prize is the MX Rider, the first-ever “motocross bike” in game.
Digging around online, I found a pic of the exact bike that inspired what we have in game:
That said, I can’t find more info about who made these bikes and when, apart from comments saying they believe this is the Canadian version of the Yamaha Moto-Bike, and it was made in the 70’s.
The bike is rated just 1 star for aero and weight, meaning it’s not going to perform particularly well on flat or climbs. And you can’t upgrade the wheels, since there is only one wheelset that fits it in game.
While riders will intuitively know that using the MX Rider in races against road bikes isn’t a good idea, we also know it’s fun to pull a “funny bike” out for the occasional Zwift group ride or recovery spin. So we put it through our typical speed tests, to see just how fast (or slow) it is.

Here’s everything you need to know about the performance of the new MX Rider bike in Zwift.
Aero (Flat/Rolling) Performance
While the MX Rider isn’t the best aero performer, it’s also faster in game than it would be in real life!
It is actually 16.7 seconds faster than the Zwift Steel (with 32mm carbon wheels) across an hour of riding on our flat test course, and you’ll probably agree is a bit optimistic. This isn’t a bad thing, though: it means people can have fun using it without taking a huge performance hit.
Climb Performance
Unsurprisingly, this bike’s performance on our long climb test was dismal. It came in slower than all the road and gravel bikes, but faster than the mountain bikes.
In fact, it loses almost 4 minutes (232.8 seconds, to be precise) across an hour of riding compared to our baseline Zwift Carbon frame + 32mm wheels.
Note: all test results above are from a 75kg, 183cm rider holding 300W steady.
Stuck With the Wheels
It’s hard to give an apples-to-apples comparison of the MX Rider vs other frames, since you can’t modify the wheels on the MX Rider. (Note: There are other bikes in game that behave this way, including the Tron bike, BMX Bandit, Brompton P Line, all mountain bikes, and the handcycle.)
The MX Rider will be beaten by almost any road frame in game, once you upgrade that frame’s wheels to anything faster than the stock 32mm carbon hoops.
Conclusions
The MX Rider performs essentially the same as last year’s Big Spin bike, the BMX Bandit. (In fact, I have a hunch both bikes have the same weight and CdA settings.) It’s not a bike you’d want to race, but if you want something that’s fun to ride on recovery days or in group rides where you don’t mind working a bit harder, it’ll be a welcome addition to your garage.
Oh, and just in case you’re wondering: it does have a color slider!

We don't always revise posts when performance rankings change, but we do keep current, master versions of our speed test results which are always available.
