Leaperkim/Veteran Abrams Electric Unicycle
The Veteran Abrams is the second wheel for LeaperKim. The Abrams is available with a 116V wheel and a 22″ by 2.75″ tubeless tire. The battery is slightly smaller than Sherman’s, containing 21700 Samsung 50E cells and 2700 Wh. The battery pack containing 21700 cells requires 33% fewer cells per Wh than one containing 18650 cells. The switch to 21700 battery cells reduces the wheel’s current weight by 44 kg. The advertised range is between 150 and 200 kilometers, which obviously varies based on riding style, rider weight, the chosen route, and other factors. We estimate the range to be between 100 and 120 kilometers.
This is one of the best EUC cruiser wheels available. This model is very comfortable for seated rides thanks to the tire, the tall body of the wheel, and the extra-wide pedals. The higher front rollbar is advantageous for seated riding because the rider can grip it. The wheel appears to have been designed specifically for riders who enjoy comfortable cruising and do not wish to consider hitting a small pothole. The large tire enhances comfort, and this wheel is unaffected by road imperfections or potholes.
The “Offroad” marking on the shells is indicative of the motor’s 3500W output. However, given the size and weight of the wheel, this model may not be ideal for all off-roaders. However, the wheel is fully capable of long, comfortable cruises, which we find to be a great feature.
THE HEADLIGHT
The four-eyed headlight is powerful and adjustable, allowing you to direct the beam upwards or downwards.
THE Pedals
The Abrams are equipped from the factory with extra-large 26.4 cm pedals with studs. A magnet is used in place of the closing mechanism. The clearance of the pedals from the ground is 17.8 cm.
THE LCD DEVICE
Using the LCD display located on the top shell, you can monitor and control the unicycle’s primary parameters and functions. The speed, voltage, mileage, battery status, switch to riding mode, pedal dipping, etc. can all be viewed on the screen.
TIRES
The tire size is 2.75 by 17 inches (if the rim is measured) or 2.75 by 22.5 inches (if the outer diameter is measured). On the tire itself, you can find additional helpful information such as weight, pressure, etc.
