Maker Builds 90,000-Watt Electric Scooter and Hit 99.4 MPH

Few electric scooters can touch 70 mph, let alone flirt with 100. Determined to close that gap himself, President Chay spent several weeks in his workshop piecing together something truly out of the ordinary. At the heart of it were three QS273 motors, each capable of putting out 30,000 watts on their own, adding up to a staggering 90,000 watts at peak output. Power came from three separate battery packs, each running at 72 volts and 45 amp hours, with every single pack requiring 600 individual lithium ion cells to build.

All that battery capacity translated directly into range, with calculations suggesting the scooter could cover more than 100 miles on a full charge. Keeping everything stable under that kind of weight and power was its own engineering challenge, and the answer was a robust aluminum frame built to absorb the stress without flexing. Dirt bike forks handled the front end, while custom steel brackets at the rear kept the axles locked firmly in place. Additional bracing was added around the neck and the belly of the frame to house all the electronics and keep the whole thing composed when the torque really starts to build.

Suspension came next, with simple shocks and pillow block bushings fitted to keep all four wheels planted on even the roughest surfaces. By the time everything was bolted together and a rider climbed aboard, the whole machine tipped the scales at 400 pounds. Hit full throttle and none of that weight seemed to matter in the slightest. Fifty miles per hour arrived in roughly two seconds, leaving a very convincing set of black marks on the pavement as proof.

Testing started with a single motor on a controlled stand, and the numbers were immediately eye opening, with wheel speed climbing past 120 miles per hour before hitting its limits. Out on the open road with all three motors singing together, things got seriously interesting. The quickest run saw the GPS clock 99.4 miles per hour, close enough to the century mark that the team celebrated as though they had actually cracked it. What nobody quite expected was how planted and composed the scooter felt at those speeds. They even had the rider lift both hands off the handlebars for a stretch, and the scooter just carried on without so much as a wobble.

The ultimate test came in the form of a side by side drag race against a stock Gotrax scooter, and it was over almost before it began. The custom build launched off the line and was gone, leaving the Gotrax looking rather sorry for itself. Even after all those high speed runs the range held up impressively well, which was a result in itself.
