Leaperkim Veteran Patton-S Electric Unicycle
The 126V Champion, Modernized
The Veteran Patton-S is an iterative upgrade upon the popular first-gen Patton, adding key features from more recent Leaperkim releases such as hall-less operation for enhanced riding safety, smart BMS functionality for monitoring battery temperatures and cell voltages, and progressive coils in all shock weights for better bottom-out protection. Other small changes include CNC motor brackets for improved durability and longevity, and a switch from the softer J802 knobby tire to the YuanXing tire from the V14, which offers a longer tread life and better ride feel for mixed use on and off-road.
In addition, Leaperkim has managed to shave almost 10lbs off the total weight compared to the previous Patton, which is a win on all fronts, allowing for better handling both while riding and while transporting the Wheel.
The Patton-S retains the same outstanding performance of the original Patton, continuing to offer an amazing combination of excellent build quality/resilience, torque, speed, and now weight. The FastAce hydraulic suspension used on the Patton-S and all other Leaperkim suspension wheels continues to be the best suspension system on the market, and with all these factors in mind, it's easy to see why the Patton-S is sure to build upon the success of the much-loved original Patton.

Battery Pack:
126V 2,220WH Samsung 50S, now with Smart BMS functionality
In ideal riding conditions (smooth surface, medium mode, 160 lbs rider, moderate 20 mph speeds), the Patton-S can output up to 70 miles of riding or commute range per charge. Thrillseekers taking the Patton-S off-road, up steep climbs, and high gradients can expect 30 to 60 miles 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 new BMS allows for 20A 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.
- Real-world riding range can vary between 30-70 miles of fast or slow-speed riding
- 126V system provides unbelievable speed and off-the-line torque
- Samsung 50S features higher density, higher discharge, and lower internal resistance than standard electric unicycle battery pack cells
- Low battery mode: low voltage, tilt back alarms
Suspension:
Fastace Mid-mount Suspension 80MM
The mid-mount suspension system by FastAce and Leaperkim continues to provide the best dampening and comfort on the market. The hydraulic system uses FactAce technology from downhill mountain biking. It has 12/18 clicks of compression and rebound, 12mm preload adjustments, a 37mm stanchion, and an overall shock absorption strike of 80mm.
Many EUC riders in the community have praised Leaperkim wheels like the Sherman-S & Lynx for having the most comfortable suspension systems on the market; the Patton uses the same patented suspension technology. There are three weight options to choose from. Please reach out to us if you need recommendations. Please note that suspension modules are swappable; please consider full netload when selecting options.
- 62 lbs Options: for riders weighing up to 175 lbs
- 66 lbs Options: for riders weighing up to 175-240 lbs
- 70 lbs Options: for riders weighing up to 240+ lbs
Features:
The Patton-S shares many features with the original Patton, giving 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.
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. These improved pedals from the Patton improve 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.
Firmware/Software Updates: Now present on the Patton-S, hall-less motor control allows for safe operation in the event of a hall sensor failure, eliminating one of the historical causes of cutouts. Acceleration assist has also been added, which provides additional pedal softness when accelerating for faster take-off.
Build Quality:
While the Patton-S commands a premium price, it is also a heavy-duty machine and was made to withstand hard falls or spills. The 81-pound chassis of the Patton-S is Leaperkim’s latest and 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 magnesium alloy blend on the battery boxes was modified to help the Patton-S achieve a reduction in weight compared to the previous Patton, borrowed from the Lynx.
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 as well as older ones with the Patton, we can see that the 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.
- First-in-class 7071 wheels with alloy components for lightweight chassis, strength, corrosion resistance, and machinability
- Leaperkim features some of the highest-created chassis in the EUC market
- Patton-S chassis was designed to be strong, durable, lightweight, and provide a high level of protection to its battery pack and core components, essential to the performance and reliability of this machine for the long term
- eWheels units go through thorough 3rd party QA inspection for battery packs, motors, firmware, and more
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. 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 Lynx, 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 (per parallel) 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.
