Biktrix Juggernaut Hub Duo Step-Over 2 vs Ariel Rider X-Class 60V PPB
Two off-road e-bikes at a similar price, compared on the same normalized specs. Both scored by us, both reviewed in full.
The verdict
The $200 price gap is small next to the real gap in torque, battery, and motor power, so the X-Class is the better buy unless the 30 lb weight difference or the single-speed drivetrain is a dealbreaker for you.
Buy the Biktrix Juggernaut Hub Duo Step-Over 2
Buy the Juggernaut Hub Duo if you want to keep the price down and the weight manageable (85.8 lb vs 116 lb), and you'd rather have a 9-speed drivetrain to help on varied terrain than raw motor power.
Buy the Ariel Rider X-Class 60V PPB
Buy the X-Class if you actually need to climb or haul stuff, its 132 Nm of torque and 750W bigger motor make the extra $200 worth it, and its 1190 Wh larger battery backs up its higher range claim.

- Ariel Rider X-Class 60V PPB pulls harder from a stop and on hills, by 52 Nm of torque.

The short version on each
Biktrix Juggernaut Hub Duo Step-Over 2
What's good
- The 910Wh battery is genuinely big for a fat bike, so the claimed 70 miles gives you a real buffer for long backcountry loops.
- 80 Nm of torque pulls a loaded bike away from a dead stop and up moderate grades without a fight.
- The parts punch above the price: Star Union dual-piston hydraulic disc brakes on 180mm rotors and a 9-speed Shimano CUES drivetrain are a step up from what usually shows up here.
What to know
- Power is the soft spot for its class. This hub motor pulls well from low down but lacks the top-end bite of stronger rivals, and Biktrix doesn't publish a peak wattage, so it can feel taxed on the longest, steepest climbs.
- Value is only okay for the class. A few rivals deliver similar all-terrain range for a little less money.
Ariel Rider X-Class 60V PPB
What's good
- The dual battery holds a huge 2,100Wh, which is why claimed range reaches 105 miles. You can ride hard for hours before charging even crosses your mind.
- With 132 Nm of torque behind a 1,500W rear hub motor, the X-Class hauls a loaded bike up steep, loose climbs without stalling out.
- A throttle means you can pull away from a dead stop on a hill or coast along without pedaling when your legs are done, no shifting or spinning required.
What to know
- At 116 lb, it's one of the heaviest bikes in its class, so loading it onto a hitch rack or into a truck bed is a two-person job.
- The single-speed KMC S1 drivetrain gives you just one gear, so pedaling does little once you're rolling and you'll depend on the motor almost all the time.
