Unboxing, assembly, and first‑ride impressions of the HighKeep MAS — a dirt‑bike style ebike with aggressive knobby tires, big rear motor, 52V battery pack, unique 4‑shock rear end, and NFC key/app unlock. I walk through box contents, build/assembly notes, controller and motor inspection, initial road top speed, suspension feel, off‑road capability, hill climbs, and early range impressions.
Quick Specs (from unbox/inspection)
Battery / Controller: 52V system; controller ~42A (tested)
Motor: Rear hub stamped 3,000W continuous (manufacturer claims up to 4,000W peak)
Tires: 20 x 4.0" aggressive knobby off‑road tires (heavy)
Suspension: 4 rear shocks / soft rear, stiff front (non‑adjustable front)
Drive: Twist throttle (PAS unclear on this unit)
Security: NFC cards + app unlock
Extras: LED light bar, pump, keys, accessories kit in box
Top Findings / Highlights
Assembly: Well‑packaged; accessories box very complete; solid wire management and heavy rear motor.
Controller math: 52V × 42A ≈ ~2,200–2,500W continuous expected (peaks possible, 4,000W unlikely without higher amp controller).
Top speed (first ride): ~37–38 mph on factory knobby tires (needed long run‑up; lighter/swapping in street tires might raise top speed).
Acceleration: Smooth throttle ramp — no hard wheelie launches; good low‑end traction off‑road.
Suspension: Rear is very soft / prone to bottoming on big hits; front surprisingly stiff.
Off‑road: Excellent capability — climbs, traction; ideal for private land/ATV trails rather than daily street commuting.
App/NFC: Useful app unlock fallback if you lose NFC card.

Who this bike is for
Property owners, hunters, or riders who want a dirt‑bike‑feeling ebike and real off‑road capability
Folks who prioritize traction/torque and rugged tires over high street top speed or long pedal range
Not ideal as a dedicated street commuter in stock knobby configuration (swap tires if you want higher flat‑road speed and lower rolling resistance)
Thank you to Hikeep for providing the MA-S bike for testing and review.
Ride Safe!
