The Engineering

Built On Better Technology

King Goat reinforced alloy frame and adjustable rear suspension

Frame & Suspension

Reinforced alloy, built for 72V power and 450 lbs.

Reinforced Aluminum Alloy Frame

A stout alloy frame and matching fenders carry a 450 lb rider limit and keep everything planted under 8,000 watts of mid-drive torque.

TRAMA Inverted Front Forks

20" hydraulic inverted forks give 100mm of travel with lockout and rebound adjustment — a genuine dirt-bike front end, not a bicycle fork.

FASTACE Adjustable Rear Shock

A fully adjustable 450–900 lb coil shock out back lets you tune traction and comfort to your weight and terrain.

King Goat patent-pending mid-drive motor, chain and drivetrain

Motor & Drive

Patent-pending mid-drive, 8,000W peak.

Custom Mid-Drive Motor

A patent-pending mid-drive rated at 3,500W peaks near 8,000 watts and 320 Nm — routed through the chain for real torque multiplication and climbing grunt.

72V 95A 18-MOSFET Controller

A high-performance 18-MOSFET controller feeds the motor hard, with an upgraded 1:3.6 gear ratio on the V3 for sharper acceleration.

Regenerative Braking

Regen braking recovers energy and helps top the battery back up as you slow — and adds a layer of engine-braking feel on descents.

King Goat 72V integrated battery box and taillight

Battery & Power

72V Samsung-celled pack.

72V 40Ah Integrated Battery

Built on Samsung 21700-50GB cells for 2,880 Wh of capacity, charging all the way to 84 volts for maximum punch off the line.

Real-World Range

Up to 80 miles in Eco or around 31 miles when you're pinning it in Sport — pick your mode to trade top speed for distance.

~4–5 Hour Charge

A UL-certified 84V 10A charger refills the pack in roughly four to five hours, so it's ready to rip again by morning.

The Cockpit

Everything On One Screen

Full-Colour LCD + App Control (antitheft startup code)

The King Goat runs off a bright full-colour display that shows your speed, live wattage, battery volts, trip data and which of the four ride modes you're in — plus a volt and watt meter so you always know exactly what the pack is doing.

It's wired for the modern rider: Bluetooth and an optional navigation app, a USB-C port to keep your phone alive, integrated LED lighting with turn signals, premium side mirrors and a loud horn. Set an antitheft startup code so it won't move without you.

This is a big, heavy dirt-bike-style machine — a 34.7" seat height and 179 lb curb weight mean it rides tall and you'll want a truck or a proper ramp to move it. It ships in two boxes (bike + battery). Shorter riders should test the reach before committing.

The Bike Cave Verdict

Ben's Take

I'll just say it: this is the best-quality, best-feeling bike I've ever thrown a leg over — and after a few hours in the saddle, it's the most comfortable bike I've ever been on, bar none. The patent-pending 8,000-watt mid-drive gives you real e-moto torque and 320 Nm, but with working pedals, so you get the best of both worlds. Bone stock in Sport mode I saw 52 mph on the GPS and pulled 38–39 up a hill — and I can't wait to feel it with the punchier controller and second battery they're sending. It's quieter than a chain-driven mid-drive has any right to be; I hear more wind in my ears than motor. The inverted hydraulic forks and FASTACE coil shock are buttery, those 20×4 Innovas and mag wheels are fantastic, and the faux-leather seat is a couch. It's a big bike — I'm 5'9" and set mine up with a shorter stem, tall bars and short cranks so it fits me like a glove. It ships fully legal as a Class 2; unlocking its full potential is on you, so respect it and ride safe. If you want a bike powerful enough to give you goosebumps, with four modes for whatever's in front of you, come look at this one. You won't regret it. I promise.

👍 What I loved

  • Best-quality, best-feeling bike I've ridden — and the most comfortable, bar none
  • 8,000W mid-drive with 320 Nm and working pedals — e-moto torque, still bike-legal
  • 52 mph on the GPS bone stock in Sport, before the upgraded controller
  • Surprisingly quiet for a chain mid-drive — more wind noise than motor
  • Inverted hydraulic forks + FASTACE coil shock + 20×4 Innovas = buttery, planted ride
  • Ships 90% assembled with all the tools and a fast charger; kickstand safety sensor

👎 What to know

  • Big, long bike — at 5'9" I swapped the stem, bars and cranks to dial in my fit
  • Stock off-the-line torque is manageable, not wheelie-punchy — a punchier controller is coming
  • Heavy at 179 lbs (over 200 with the second battery) — you'll want a ramp
  • Ships locked to Class 2; unlocking full power is on you, so ride responsibly
