What the stars are rated against

The stars compare this bike with other off-road e-bikes we have scored — 27 of them, priced $1,540–$2,860. They are a ranking inside that group, not an absolute grade: four stars means it beats most of that set on the measure, not that it hits some fixed standard.

Peers are drawn from a tight price band around this bike, so a $1,000 commuter is judged against other $1,000 commuters rather than against machines costing three times as much. Change the group and the stars would change with it.

The headline Genius Score is not decided by that group alone. It blends the category ranking above with a market-wide view across every bike we publish, so a bike cannot climb simply by sitting in a weak category. How we score.

The Mokwheel Obsidian ST 2.0 is built to roam. With and a big battery on board, it pulls up loose dirt and long grades, then keeps enough charge to let you keep going instead of turning back early. It's a bike with a , so you can cruise without pedaling up to 20 mph and let carry you to 28 mph when you want to move.

What tips it from good to genuinely worth the money is how it's put together. You get a Shimano 10-speed drivetrain, , and thick puncture-resistant fat tires that don't feel like corners were cut. At $2,199.99 you're paying mid-tier money for mid-tier capability, which is how it lands a 79 out of 100 Genius Score. The range and climbing muscle are what you're really paying for, and they deliver.

Best for: Riders who split their time between trails and pavement and want a big battery, strong climbing, and the option to ride on throttle alone.
The trade-offs

Pros & cons

What we like

  • from the pulls a loaded bike up steep, loose climbs without bogging down.
  • A roughly 940Wh backs up the rating, so long days out don't have you watching the charge.
  • Strong parts for the price, including a Shimano 10-speed drivetrain, Tektro hydraulic disc brakes, and puncture-resistant fat tires.
  • A takes over on hills and standing starts, powering the bike to 20 mph with your feet off the pedals.
  • A 560-pound gives you room for a passenger seat, panniers, or a heavy cargo load without straining the frame.

Worth weighing

  • You're paying a fair mid-tier price for the capability, not a bargain; if you don't need the range and torque, lighter fat-tire bikes cost less.
  • Suspension details aren't published, so confirm what it ships with before you count on it for really rocky trails.

The detail

The motor & power

The heart of this bike is a 750W making . That much twisting force is exactly what you want on an off-road bike, because it's what gets a heavy, loaded machine moving up a steep grade instead of stalling halfway.

The power comes on as a steady, even pull, which is easy to manage on loose climbs and rough ground where a sudden surge would just spin the tire. On the very steepest, slowest technical sections a would gear down with you and cope better, but that's not the riding this bike is built for. For the mix of trail and pavement it's aimed at, the consistent push does the job well.

Genius tip

Mokwheel lists this motor three ways: 750W rated, 1000W continuous, and a . The peak only shows up in short bursts, like the first moment of a hard climb, so judge everyday performance on the 750-to-1000W steady output, which is plenty for this kind of riding.

Range & battery

The 48V, 19.6Ah pack works out to about 940 , which is a genuinely big battery. It's the main reason the rating holds up as a believable best case.

That 80-mile figure assumes flat ground, light pedaling, and easy conditions. On hilly trails, under load, or with heavy throttle use, your real number comes down. Even so, a battery this big leaves plenty of cushion for a full day out before charging enters your mind.

Ride & components

This is where the Obsidian earns its keep. The parts list is a step above what a lot of fat-tire bikes hang on at this price.

Stopping comes from , which give you firm, controlled braking even on a loaded downhill. The Shimano 10-speed drivetrain has a wide enough gear range that you can keep pedaling at speed instead of spinning out.

The 26-by-4-inch fat tires are puncture-resistant, so they roll over sand, gravel, and roots with less chance of leaving you patching a flat miles from the car.

At 77 pounds it's a substantial bike, which is normal for a fat-tire build carrying a battery this size. Just plan for the heft when you're lifting it onto a car rack.

Price & value

At $2,199.99, the Obsidian ST 2.0 sits in the middle of the fat-tire market, and the price lines up with what you actually get. You're spending real money here, and the big battery, strong climbing, and quality parts are what earns it.

If your riding is mostly smooth pavement, you can find lighter and cheaper bikes that handle the daily job just as well. The reason to spend here is the combination of long range and genuine off-road ability in a single machine.

Genius tip

Mokwheel rates the , which is unusually high for the class. Think of it as breathing room rather than a target: even a large rider with a fully loaded rack stays well under it, so you never have to second-guess what you're carrying.

Match it to your ride

Who it's for

Great fit

The trail-and-town explorer

If your weekends mean dirt, gravel, and the odd paved stretch to get there, this bike covers all of it. The of climbing muscle gets you up loose grades, and the big battery means you can wander for hours without planning the whole ride around the next outlet.

Great fit

The rider who'd rather not pedal every hill

If you like the idea of easing off and letting the bike do the work, the handles it, powering you to 20 mph while you just steer. That's a real relief at the end of a long day or when you're muscling a heavy bike away from a dead stop.

Look closer

The pavement-only commuter

If nearly all your miles are on smooth city streets, this is more bike than you need. The fat tires and 77-pound frame are built for terrain you may never touch, and a lighter commuter would cost less and be easier to live with day to day.

Look closer

The technical singletrack rider

If you're chasing tight, steep, low-speed trail work, a motor handles that better than this bike's hub motor. The suspension setup also isn't published here, so serious rock gardens are worth a closer look before you commit.

Same family

How it compares to its siblings

The Obsidian ST 2.0 matches the Obsidian 2.0 on every spec - 10-speed drivetrain, $2199.99 price, 105Nm torque, 940.8Wh battery, 77 lb weight, and a Genius score of 79 - so there's no functional reason to pick between them. Compared to the base Obsidian ST, this one adds two more gears for $200 more, but the Genius score drops a point (79 vs 80), so the extra speeds don't come with a testing edge. If the wider gear range isn't a priority, the plain Obsidian ST is the cheaper, higher-scoring pick.
