Leaperkim Sherman P - Best long range wheel ever build?

The electric unicycle (EUC) community has a fierce new contender for the throne of long-range street performance. Released in September 2026, the Leaperkim Sherman P arrives as the direct successor to the highly regarded Sherman-L. It establishes an incredibly high benchmark for high-speed cruising, raw power, and battery endurance.
While the Sherman-L was celebrated for its stability and cruising comfort, the Sherman P radically modernizes the platform. It incorporates a higher-voltage architecture, a massively scaled battery pack, and next-generation thermal management.

Unprecedented Battery Capacity and Smart Safety

The definitive upgrade of the Sherman P is its massive 4,700 Wh battery pack utilizing high-discharge Samsung 50S cells. Leaperkim has managed to pack Oryx-tier energy density directly into a compact frame that shares a nearly identical footprint to the previous Sherman-L.
To protect this immense reservoir of power, Leaperkim introduced BMS 3.0. This intelligent battery management system monitors individual cell variance carefully. It features active power-off cell balancing, meaning it will safely adjust string variances even after the unicycle has been turned off. Alongside low-voltage, short-circuit, and overcharge protections, the 176.4V system provides a colossal safety margin. It dramatically reduces the risk of high-speed cutouts by keeping voltage sag at bay.

Aggressive Powertrain and Thermal Dynamics

Driven by a heavy-duty, double-layer aluminum substrate controller capable of blasting 960A of max phase current, the Sherman P handles intense electrical loads with ease. The controller utilizes custom copper busbars to dissipate heat rapidly away from the MOSFETs.
This monstrous electronics bay feeds a custom 3,800W motor outfitted with 42mm magnets and re-engineered windings. The result is a jaw-dropping 351 Nm of peak torque. This delivers dual enhancements: a punishing, instantaneous low-end acceleration and a higher real-world top speed than even the nimble Leaperkim Lynx. The motor also benefits from an upgraded Hall sensorless algorithm and anti-blocking protection to ensure continuous operation if hardware anomalies occur.

Build, Suspension, and Comfort Changes

To cope with the immense forces generated by a 10,000W peak motor, the Sherman P features an ultra-rigid magnesium-alloy chassis protected by IPX6 weather resistance.
For riders taming high-speed highway bumps or local trails, the wheel brings a re-tuned 90mm hydraulic suspension system featuring a progressive spring and an integrated airbag bump-stop. Other notable hardware updates include:
• Enhanced Lighting: A powerful, motorcycle-grade 3,000-lumen (25W) headlight with a clear cutoff beam and daytime running lights to avoid blinding oncoming traffic.
• Ergonomics: Adjustable height pedals, integrated tow hooks, and a solid metal trolley handle.
• The Weight Trade-off: The massive addition of battery cells and heavy-duty cooling elements shifts the scales to 52 kg (114 lbs). This makes it roughly 5.5 kg heavier than the Sherman-L, cementing it strictly as a dedicated high-speed cruiser rather than a lightweight trick wheel.

Availability and Verdict

The Leaperkim Sherman P represents an uncompromising step forward for experienced riders looking to dominate open asphalt. With retail pre-orders priced around €4,299 / $4,300, it is a premium investment for long-range touring professionals.
