Daymark’s Wireless Shadow eBike
It was the snowiest February on record around here, and there’s more on the way. But spring isn’t far off, and we’re already gearing up for bike season. We’ve done a number of posts on electric bicycles, but one company has taken it to the next level, with “the world’s first wireless power-assist electric bicycle.” Daymark’s new Shadow eBike “boasts a USB port, a charging port, an LED battery power display, regenerative breaks and a wheel that doubles up as a generator!” The circuitry is entirely in-frame, including an electric motor, lithium polymer battery, magnetic regenerative brakes, throttle and the pedal-assist functions which use a 2.5 GHz frequency-hopping “spread-spectrum technology”.
The bike comes with either a 250W or 350W electric motor, and a lithium-ion battery that can provide an average range of around 12 to 15 miles running on just motor power. With pedal-assisted power, this range is extended to 22 to 25 miles. The battery recharges in about five hours as is good for up to 800 cycles. The bike’s wheel also doubles up as a generator able to charge devices via the USB port, and a regenerative braking system sends a current back to the batteries. The bike, which arrives next month, will cost $1,999.
