Biktrix Juggernaut Ultra Duo 4 Step-Over vs Cyrusher Trident
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
With torque tied at 160 Nm and Genius scores basically identical (71 vs 70), this comes down to whether you value lighter and cheaper (Juggernaut) or higher payload and stronger brakes (Trident), not which bike is better.
Buy the Biktrix Juggernaut Ultra Duo 4 Step-Over
Buy the Juggernaut Ultra Duo 4 if price and weight matter most: it's $600 cheaper and 13 lb lighter, which counts for real if you're lifting it onto a rack or up steps. Just don't fully trust its 95-mile range claim over the Trident's 75 given it actually carries less battery (910 Wh vs 1040 Wh).
Buy the Cyrusher Trident
Buy the Trident if you need to haul more weight or brake harder: its payload capacity is 60 lb higher (440 vs 380) and its brakes are a beefier 4-piston 203mm setup versus the Biktrix's dual-piston 180mm. You're paying $600 more and carrying an extra 13 lb for that.
The differences that matter
- Biktrix Juggernaut Ultra Duo 4 Step-Over costs $600 less.
- Cyrusher Trident carries 130 Wh more battery, which is the main thing that sets how far you get.
- Biktrix Juggernaut Ultra Duo 4 Step-Over is 13 lb lighter, which you notice lifting it or carrying it up steps.
- Biktrix Juggernaut Ultra Duo 4 Step-Over claims 20 more miles of range, though both figures are the manufacturer's optimistic "up to" number.

The short version on each
Biktrix Juggernaut Ultra Duo 4 Step-Over
What's good
- A 1000W Bafang Ultra M620 mid-drive with 160 Nm of torque gives it real climbing muscle, and because it works through the gears, steep and loose is where it feels strongest.
- The 910Wh battery is big enough for long backcountry days, and the frame will take a second pack if you want to stretch a day trip into an overnighter.
- A throttle lets you pull away without pedaling up to 20 mph, which is a genuine help for tricky starts partway up a climb.
What to know
- The 180mm hydraulic disc brake rotors are on the small side for a machine this heavy and this powerful; on long, loaded descents, larger rotors would shed heat and keep their bite better.
- For $3,499, the Shimano Alivio 9-speed drivetrain is fairly basic for the price.
Cyrusher Trident
What's good
- One of the strongest motors you'll find on a fat-tire bike: 160 Nm from the Bafang M620 mid-drive for steep, technical climbing.
- A large 1,040Wh battery backs up the claimed 75-mile range, so real all-day rides are on the table.
- Four-piston hydraulic brakes with big 203mm rotors give you the stopping power a heavy, fast bike needs.
What to know
- At 101.3 pounds it's heavy even for a fat-tire bike, so getting it onto a car rack or up a step is a two-person job.
- Cyrusher doesn't publish suspension travel figures, which is a gap worth asking about on a bike sold for rough terrain.
