Residents of Philadelphia, beware: You may even see a grown man whizzing by you on a skateboard, doing 20 mph. That might be PopSci employees photographer John Carnett, and in case you don’t get a great look, it’s a souped-up, motorized board he constructed from the bottom up.
Carnett needed to create a motorized skateboard that might be superior to business fashions—a quick, hot-looking board that ran on all terrains. He began by reducing a shiny 44-inch-long aluminum deck and bending the ends and aspect rails. In order that it may transfer simply from pavement to path, he outfitted it with sturdy axles and eight-inch inflatable knobby tires.
Then there was the matter of putting in a disc-braking system and a 500-watt electrical motor. And since no wheel bearings existed that match each the truck axle and his customized drive system, Carnett needed to cobble collectively and weld an aluminum adapter plate to make every thing match. Then he connected a field to the underside that holds the motor controller and 4 batteries; when the primary two die, the board can go one other eight miles on the backups. Or he can let the board do the climbing work, after which energy it off and freewheel downhill. Both manner, it’s the sweetest experience on the highway—or off it.

The PopSci All Terrain Skateboard
How It Works
Value: $800 | Time: 3 days
Energy: The motor runs on 24 volts from two sealed lead-acid batteries, and drives the again wheels with a series. Carnett plans to improve to polymer lithium-ion batteries to shave off about 12 of the board’s 60 kilos.
Going: The rider accelerates utilizing a pistol-like set off linked to a management field with a wire. The set off and wire might be coiled and stowed when driving freewheel, so no electrical elements get broken or pose a hazard within the occasion of a crash.
Stopping: To decelerate, the rider squeezes a grip just like a bike brake held within the different hand, activating a rear-wheel disc brake that may cease the board far faster than the regenerative-braking programs electrical boards sometimes use.
