The Veteran Patton is poised to dominate the electric unicycle scene in 2023 with its unparalleled performance and exhilarating torque, earning praise from EUC enthusiasts worldwide. Let’s delve into the specifications, features, and design elements that make the Patton the ultimate choice for daily commuters and long-distance adventurers.
Power:
High Torque Motor
The Patton boasts a peak power rating of 7 KW, capable of delivering 680A of peak current and reaching speeds of up to 80 km/h on a full charge. Leaperkim has ingeniously packed 126 volts of torque into this 18-inch wheel, providing unmatched performance. Despite its weight of 40.37 kilograms, the Patton remains stable, thanks to its sturdy chassis. The updated controller system allows riders to customize power settings according to their preferences.
Featuring a double-layered 126V controller for enhanced protection, an aluminum substrate for efficient heat conduction, and copper bars and columns for accelerated heat dissipation, the Patton ensures optimal performance under heavy loads.
The Patton's motor, crafted from magnesium alloy, features reinforced rims and side covers, along with an oil-sealed waterproofing process on the bearings. With a nominal or peak power output of 3KW or 7 KW, respectively, the Patton sets new standards in electric unicycle performance. Additionally, Leaperkim has introduced a Bluetooth-enabled Android app, enabling riders to access system diagnostics and customize settings via their smartphones.
With a top speed ranging between 72-80 km/h, depending on rider weight and road conditions, the Patton offers exhilarating acceleration and effortless hill climbing capabilities. The inclusion of two-layered top panels enhances protection against water damage, corrosion, electrical shorts, and physical damage, while also waterproofing the controller. A larger display provides comprehensive ride information, and the high-speed mode allows for maximum free spin at speeds of up to 83.7 km/h, or 104.6 km/h with high-speed mode activated. Furthermore, the angle protection feature offers eight levels of adjustment, allowing riders to fine-tune their acceleration stance.
Battery Pack:
126V 2,220WH Samsung 50S
In ideal riding conditions (smooth surface, medium mode, 72.57 kg rider, moderate 32.19 km/h speeds), the Patton can output up to 112.65 kilometres of riding or commute range per charge. Thrillseekers taking the Patton off-road, up steep climbs, and high gradients can expect 48.28 to 96.56 kilometres of mixed-conditions EUC riding.
The 126V Samsung Packs use INR217000-50S cells, 2,220 watt-hour capacity (2 sets, 30 strings, 2 parallel configurations), and BMS monitoring for charging rate and temperature (more details to come). The BMS allows for 15A max dual charge ports, allowing owners to fast charge their wheels last minute before a commute to the office or during a group ride rest stop. Leaperkim has also added anti-collision energy-absorption boxes to the packs, making them safer in a fall.
All of our Leaperkim battery packs go through stringent QC checks before shipping to our warehouses; they’re covered under our one-year warranty and should last many years.

29.94 kg Options: for riders weighing up to 108.86+ kg
Features:
The Patton features are designed to give this industrial wheel an all-terrain design with useful everyday amenities.
Display: The updated top-mounted parameter display has a more extensive interface, shows more technical parameters, has a two-layer inner and outer cover, and is better protected from rain.
Trolley Handle: Leaperkim chose a classic studier handle over the newer folding style. These built-in handles are firmer, adjustable in height, and sturdier by design.
Jumping Aide: The new front-mounted help gives you more control when going over rougher terrain. Leaperkim is the first to introduce this style of adjustable module. Please be aware that the Patton can’t reach its full potential without jumping pads that you buy separately. Leaperkim has not released side pads for this iteration. We stock aftermarket side pads that can be velcroed on the side panels for more control.
Spiked Pedals: The adjustable pedals are made of Magnesium alloy, which makes them more durable, and they have loaded tension to make them more stable and stop them from flapping around when you’re getting on or off. The spikes have been improved from the last Sherman-S iteration and allow for more grip during acceleration and braking.
External Buzzer: The external speaker will notify if the wheel is on a lower battery or near cut-out/brown-out speeds and loads. Riders can expect buzzing and tilt back when reaching lower battery voltages (97V, 94.5V, 87V)
Lighting: 2,000LM dual 18W headlights, a rear taillight, and auto-turning signals allow riders to see and be seen in day and night riding conditions. The lighting package on the Patton is some of the brightest lamps on the current market, allowing for safer riding conditions.
Build Quality:
While the Patton commands a premium price, it is also a heavy-duty machine and was made to withstand hard falls or spills. The 89-pound chassis of the Patton is Leaperkim’s most advanced design. It was created to help absorb the impact if a rider gets their wheel in a collision.
The body has a heavier, integral 7071 aviation-grade alloy body/handles and dual anti-collision battery boxes, keeping your battery packs and motor safer during a spill. The Veteran series’ design language, geometry, robust build, look and feel are molded after US military battle tanks.
With the newest crash test videos from Leaperkim, we can see that the Patton shell is unharmed, which protects the battery and solidifies Leaperkim’s reputation for making some of the most popular, well-built, and quality-controlled wheels on the EUC market.

NEW: Upgraded Samsung High-Power 50S Battery Pack
The most valuable component of any Wheel is its battery pack, the beating pulse of the machine. Over the years it has been found, from painful experience, that pairing a high-powered machine with a battery cell that is not designed for high peak-power applications can result in latent/delayed catastrophic thermal runaway events. To try to minimize this risk, we at eWheels, have insisted the use of high-powered battery cells, particularly on smaller 4 parallel packs, such as the MTen4, A2, T4, S18, Hero, S22, & Master—as the number of parallels increase, the load on each cells decreases accordingly. Until recently, there was the trade-off between power & capacity; now, with the advent of the new Samsung 50S cell, one can have both!
- Energy Density: 50S has a 20% increase in energy density over the 40T, providing a corresponding increase in range without any weight/bulk penalty.
- Higher Operating Temperatures: the specifications of the 50S has a vast operating range, from -20 to 80°C/-4 to 176°F vs -20-60°C/-4-140°F with the commonly used 50E/GB cell & as high as 100°C/212°F in Samsung’s test data! This massive margin not only allows the 50S to output up to 3x more power than the 50E, but perhaps more importantly, will greatly improve battery pack safety, there is no conceivable scenario in which these limits will ever be reached, or exceeded.
- Power Output: the maximum sustained power output on the 50s is 45A vs 15A on the 50E. At pack level, this represents a total potential sustained output of 15,120W, on the Patton. From a Rider’s perspective, the main benefit of having this power on-tap is once the pack(s) have been partially depleted, reducing the risk of cut-outs when power is required.
- Rapid-charging: another benefit of the 50s over the 50E is charging rates, 2.25x higher, 6A vs 2.5A. It should be noted that although the cell supports the higher charging current, there may be other factors that limit maximum charge rate, such as the charge-port, wiring & BMS components. On the Patton, the maximum rate of charge should not exceed 16A.
- Superior Cycle-life: perhaps the most common misconception of high-power cells is that of reduced cycle-life, but this is fundamentally a misunderstanding of the published datasheet for battery cells. In these publications, Samsung’s data is based on exceedingly high sustained loads of 25A/45A. Other Samsung materials demonstrates that in 10A continuous load scenario, the 50S commands a slight lead over the the 50E for longevity, with >82% capacity retention over 600 cycles.
It should also be noted that these synthetic tests in no way represent the power demand pattern that is experienced when using your machine, where the average load, on flat terrain, will be closer to 2-3A/cell vs the 10A in the test data—there may be periods where this demand is considerably more than the 10A, which is where the high-power cells really come into their element. In addition, the [50S] 600 cycles were charged at the maximum 6A vs a typical 1.5A with the stock charger, which also has an impact on the pack’s longevity.
In summary, the 50S battery cell is objectively superior in every measurable metric, with only a marginal increase in upfront cost. It is expected that machines fitted with these packs will retain their value better than other battery cells.
