Veteran Sherman-S, 3,600WH Battery, 3,000W Motor, Suspension

The world’s best wheel is only getting better. When Leaperkim first released the Sherman OG, its first pass at the world’s fastest wheel changed the EUC industry immediately. Until Leaperkim, no company had created such a powerful, fast, durable, dependable electric unicycle.

The Sherman was so famous that our inventory was constantly sold out, making it one of the most sought-after wheels in EUC history. The Sherman-S pushes further limits in its third form with its 7KW high-torque motor, long-range 3,600WH Samsung 50E battery pack, 24xMOSFET (680A peak) drivetrain, and full suspension co-designed by Fastace.

The community has spoken: the Sherman-S is the top contender for 2023’s best wheel, owing to its heavy-duty construction, innovative amenities, and plush 90mm travel suspension. The Sherman-S was designed with long-distance, high-speed riders in mind and torque-hungry enthusiasts looking for the best quality and value for their hard-earned money.

High Torque Motor

As the technology for lithium batteries and BLDC motors improves, the industry makes more robust and faster wheels than anyone could have imagined. For those seeking power and range, Leaperkim has fitted the Sherman-S with some of the top-performance components on the market. The SS is powered by a 3KW high-torque motor that can output 7KW power, taking the boldest of EUC riders past 46+ mph on a full charge.

Leaperkim made plenty of improvements over the original OG drivetrain by providing the SS with more robust, more comprehensive, and lighter magnesium alloy rims, improved phase wiring mounting, and 24 x 125V MOSFETs to handle larger payloads, all on top of a 3,600WH battery pack to provide plenty of high speed and long-range riding throughout the work week commute and long weekend adventure rides. 

• 3KW/7KW high torque motor for improved off-the-line acceleration and hill climbing
• High torque motor paired with suspension allows for easy mounting and quick acceleration.
• High-speed mode rated top speed up to 50 MPH and 20-40 cruising speeds are the sweet spot for most Sherman riders.
• Rims are reinforced and strengthened for motor protection, off-roading, and higher payloads.
• A magnesium alloy is used on wheels to reduce weight and increase durability.
• To improve conductivity, controllers employ phase wire copper mounts, 2x power sources for current, independent communication and driver boards, and 24xMOSFETS capable of handling 680A peak payloads.

100V 3,600WH Samsung 50E

The Sherman’s large battery pack can be used for work and pleasure, going fast for long distances. We are frequently asked how many real-world miles our machines can provide, and the Sherman-S can provide up to 90 miles of exciting real-world range on a single charge. The Sherman’s capacity and output depend on how the road is, how much it’s carrying, what mode it’s in, and how fast it’s going on average. The 3,600WH battery pack in the SS should provide more than enough range for any adult looking to work throughout the workweek.

The advantages of having such a large battery pack include less recharging time, extended power for high-speed riding, and extended capacity for long-range group rides. Many customers drive their Shermans to work, and some even use them for long-distance service work that necessitates the most massive batteries for covering large cities.

• High-quality Samsung 21700 50E cells
• Samsung 50E features higher density, higher discharge, and lower internal resistance than standard electric unicycle battery pack cells.
• BMS features low voltage protection and tilt back
• Dual power wire sources to control boards for cut-out protection
• Fantastic wheel for commuting, weekend group rides, and casual riding
• Long-range batteries allow owners to charge less frequently while maintaining higher speeds and range on more challenging routes.
• Fast chargers are available.
• Knobby tires, range, and suspension provide ideal conditions for rough terrain.
• Our customers praise the suspension, build quality, and capacity of the Sherman-S.

Fastace Mid-mount Suspension 90MM

The SS may be the plushest one-wheel electric vehicle ride to date. When the Sherman-S was first introduced, some riders in the community or skeptics of it opposed the mid-mounted suspension approach. After our first batch was sold out, the EUC community could all agree that the Sherman-S has the most innovative and most comfortable suspension system to date. Unlike other companies in the industry, Leaperkim chose to work with Fastace to create a suspension system for their franchise that was unique to them.

The mid-mounted hydraulic system uses ideas from the mountain bike industry. It dampens like a fork and has a range of up to 90mm and a pretension adjustment of 12mm. The hydraulic system is a huge step away from the air and coil options on the market. The feedback from the community is that this system is superior in ride comfort over the roughest terrain.

• 58 lbs. Options: for riders weighing up to 200 lbs.
• 62 lbs. Options: for riders weighing over 200 lbs.
• 66 lbs. Options: for riders weighing over 250 lbs.
• The highest caliber mid-mount system is preferred over existing coil and air suspension options.
• Fastace and Leaperkim collaborated to create their proprietary system, drawing inspiration from the mountain biking industry.
• The suspension provides 90mm of travel range and 12mm of pretension adjustment.
• The Sherman and Patton are equipped to have some of the best and smoothest ride quality available.

Leaperkim has fitted the Sherman-S with some of the most cutting-edge features and EUC components. Some of their exciting ideas include making parts out of magnesium alloys and rethinking different factors, like their improved display, trolley handle, side panel designs, and different rim designs and materials that can handle rough terrain and a lot of abuse.

Leaperkim is genuinely leading the way in increasing the number of machines that can be used over the long haul.

• Display: A new display that provides accurate information and improved data telemetry.
• Seat/Handle: Dual-purpose flip-up trolley and Seat
• Handles: Front and rear carrying handles protect the user in a collision.
• Side Panels: Magnesium alloy side panels for chassis and battery protection
• Lighting:  2,000lm headlights and laser tail lights for visibility and safety
• Suspension Knobs: The top exposes suspension knobs for easy access and adjustment.
• Rim: A lighter and more powerful magnesium alloy rim.
• Suspension: Fastace mid-mounted hydraulic suspension
• Adjustable spiked peals, high-strength Magnesium alloy, 260 lbs. load capacity
• Mudguards: front and rear for weather protection

Through the successes and lessons learned from the previous wheels, Leaperkim has cemented a legacy of producing some of the market’s most robust, fastest, and highest-quality wheels. Their design style and choice of materials make for the most beautiful, symmetrical, and well-balanced machines on the market. Their wheels’ general theme is robustness, modeled after US military battle tanks. The current lineup includes Sherman, Abrams, and Patton. The Sherman-S is one of the most expensive wheels because of how strong it is, how well it performs, its features, and how big its battery packs are.

The EUC community has a strong group of Sherman riders, praising its power delivery and overall strength. We’ve had a strong relationship with Leaperkim, and we can better control quality with a one-year warranty that covers any significant issues with manufacturing defects. For quality control, independent contractors inspect all of our Leaperkim inventory.
