We are big fans of electric bikes [1] here at Inhabitat, but Daymak [2] have raised the bar by creating the first ever completely wireless bike – almost. The brand new Shadow eBike [2] hosts only a bit of wiring hidden away in the front hub, still placing it far ahead its competition which will usually comes entangled within an array of wires on its frame. But beyond its sleek and clean form, this eBike also boasts a USB port, a charging port, an LED battery power display, regenerative breaks and a wheel that doubles up as a generator!

The Shadow eBike’s wireless attributes means that there are no electrical connections exposed to the elements, removing the possibility of accidental severing or short circuiting. All of the bike’s circuitry is in-frame, including its electric motor, lithium polymer battery [3], magnetic regenerative brakes, throttle and the pedal-assist functions which use a 2.5 GHz frequency-hopping “spread-spectrum technology” [4]. As such, Toronto-based Daymak feel justified in calling the Shadow “the world’s first wireless power-assist electric bicycle.”

Daymak offers the Shadow eBike equipped with either a 250W or 350W electric motor, and a 36V 10AH 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 takes between four and five hours to completely recharge and is good for 750 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.

If you are concerned that the bike’s wireless design leaves it vulnerable to hacking, don’t worry. Daymak says that each Shadow eBike wireless component is paired and the odds of it being affected by outside parties is less than one in a billion. The use of wireless technology also means the Shadow is set up for future upgrades that will one day enable it to interact with smartphones and even PCs.

The bike is set to be released on April 30th, and has been given a retail price of $1,999.
