Mokwheel’s Obsidian is big in every sense of the word. Power, frame size, tires, suspension — everything about this bike leans toward “go big or go home.” It feels a lot like driving a truck, and we mean that in the best possible way: stable, planted, and built to handle serious weight and terrain without flinching.
Currently, both the Gen 1 and Gen 2 models are available. The newer version brings some nice upgrades — mainly in the drivetrain and display — but the overall ride feel is close enough that Gen 1 ends up being the stronger value. If you want the refinements of Gen 2, you won’t regret it, but riders trying to stretch their dollars will be perfectly happy with the original.
What impressed us most was the suspension. A 50mm rear shock and 130mm fork give it true full-suspension comfort, and Mokwheel deserves credit for being one of the first reputable brands to pull off a full-suspension fat-tire bike that wasn’t wildly overpriced. More importantly, they did it well.
The ride is sturdier and more supportive than we expected, especially for a bike this heavy. We’ve tested boththe step-through and high step frames, and the ST version genuinely surprised us: no wobble, no frame flex, just a remarkably solid feel paired with full-suspension plushness (the highstep was great too). Bigger riders who prefer step-through frames will appreciate how confidence-inspiring it feels.
The Obsidian backs up its size with a 1000W hub motor (1300W peak) delivering 105Nm of torque. It supports both Class 2 and Class 3 speeds, though riders should check local trail and path rules — this much power isn’t allowed everywhere.
It performed well across the board in our testing: great range and solid braking, with one of the fastest hill ime’s we recorded at our old test hill.
This is great for people looking to do some offroad exploring. It’ll pair with an inverter and solar panel accessories, blast up steep hills, and float over different surface types.
Big riders often struggle to find a bike that feels supportive, powerful, and truly built for rugged use. The Obsidian delivers all of that and more — in a way that few bikes in this category manage.
