What the stars are rated against
The stars compare this bike with other off-road e-bikes we have scored — 36 of them, priced $850–$2,550. 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.
If your riding is a mix of gravel paths, dirt roads, and the paved streets that connect them, the Mokwheel Tarmac ST covers all of it for $1,699.99. The puts out a steady 750 watts with , enough to pull you up moderate climbs and through soft patches, and the 27.5-inch wheels roll over rough ground without much drama. What sets it apart from most off-road e-bikes is what it leaves off. At 57 pounds it undercuts the 70-plus-pound norm for the category, so it's less of a handful the moment you're off the bike.
It's a bike, so you get a that moves you up to 20 mph with no pedaling and that carries you to 28 mph when you put the effort in. That's a lot of everyday usefulness for the money. The one thing to plan around is range: the 60-mile figure is a best-case number, and mixing in hills and throttle time brings the real distance down.
Pros & cons
What we like
- At 57 pounds it's one of the lighter off-road e-bikes around, so a solo lift onto a hitch rack or up a flight of stairs is realistic.
- from the 750W motor handles moderate climbs and loose ground with confidence.
- A lets you cruise up to 20 mph without pedaling, and takes you all the way to 28 mph.
- and a solid build give you strong, steady stopping on descents and loaded rides.
- It's priced well for what it can do, so you get real trail capability without paying premium money.
Worth weighing
- Real-world range is the soft spot here; the 720Wh battery won't reliably deliver the full 60 miles once dirt, climbs, and throttle use enter the picture.
- The 2.4-inch tires run narrow for a trail bike and Mokwheel doesn't publish , so rocky, technical singletrack is likely to feel harsh.
Key specs
The motor & power
The Tarmac ST runs a 750W rated at , with peak output listed at 920 watts. On flats and gentle grades that's plenty of muscle. Power builds smoothly and evenly, which keeps it easy to manage on loose surfaces.
On steeper climbs, especially with cargo or a heavier rider aboard, 75 Nm keeps you moving but you'll feel it working. It's a capable middle-of-the-pack motor, so on the toughest pitches, pedaling along with the throttle works better than leaning on power alone.
You'll see Mokwheel quote this motor as both 750W and 920W. The 750W is the continuous output to judge it on; the 920W is a short burst you'll only feel pulling away from a stop.
Range & battery
The 48V, 15Ah pack works out to a , and Mokwheel puts the at up to 60 miles.
The 60-mile figure is realistic only on smooth ground, in a low assist level, with light pedaling. Dirt, climbs, a loaded rack, and heavy throttle use all pull it down from there. For real terrain, giving yourself a cushion under 60 is the smart way to plan a loop.
Ride & components
Stopping comes from Tektro TKD171 , which give you strong, consistent braking on downhills and loaded rides. Shifting is handled by a Shimano 8-speed drivetrain, a simple, reliable setup with enough gears for both climbing and cruising.
The 27.5 x 2.4-inch tires and 300-pound mean it'll carry you plus gear or a grocery run without complaint. Those tires lean more all-road than plush off-road, so the bike is happiest on gravel, dirt roads, and packed trails rather than rock-strewn technical descents.
At 57 pounds it's light for an off-road e-bike, and you feel it most at low speed, threading through a tight garage or muscling the bike around on a narrow trail.
You may see this bike listed at both 57 and 65 pounds. We go with 57, the figure on Mokwheel's own spec sheet.
Price & value
At $1,699.99, the Tarmac ST gives you a lot of bike for the money. You get hydraulic brakes, a 720Wh battery, a Class 3 setup with a throttle, and real trail capability at a price where plenty of off-road e-bikes feel stripped down.
That mix is why it lands a Genius Score of 76 out of 100 and rates as a strong value for its capability. The real compromises are the range and the all-road tires, neither of which is a dealbreaker for gravel-and-pavement riding.
Who it's for
The dirt-and-pavement switcher
If your typical ride blends gravel paths, dirt roads, and the paved streets between them, this is a natural fit. The 75 Nm motor and 27.5-inch tires handle the loose stuff, and up to 28 mph keeps you rolling once you hit the road.
The cruise-without-pedaling rider
If you like the option to sit back and let the do the work, it'll pull you along up to 20 mph with no pedaling at all. Leaning on it does eat into the battery, so your longest days will want some pedaling mixed in.
The technical-trail hound
If you're chasing rocky singletrack, roots, and big drops, look harder before you buy. The 2.4-inch tires and unpublished suspension steer this bike toward smoother terrain, so genuinely rough trails will beat you up.
The all-day backcountry rider
If you're planning 50-plus-mile outings far from an outlet, the 720Wh battery is the limiting factor. The 60-mile claim thins out on real terrain, so long unsupported rides are where this bike asks you to compromise.

How it compares to its siblings
Same price as the standard Tarmac, same motor, battery, brakes, and range, but the ST is 9 lb lighter and rolls on 27.5" x 2.4" tires instead of 29ers, which is why it edges out the Tarmac on Genius score (76 vs 73). The tradeoff is payload: 300 lb capacity versus the Tarmac's 350 lb. If you're near that weight limit, the standard Tarmac fits you better; otherwise the ST is the same bike for less bulk.
