rein­vent­ing the wheel

Give your push-bike an in­stant elec­tric up­grade, with a smart wheel de­signed by the en­gi­neer­ing minds at MIT…

E-BIKES MAY BE ON TREND, but THEY can also be bulky and costly. The Copen­hagen Wheel, de­signed by top tech uni MIT’s Senseable City Lab, al­lows you to up­grade your cur­rent ride by slot­ting a bat­tery pack and mo­tor neatly in­side its cen­tral red dot.

Rather than us­ing a throt­tle, the wheel re­lies on an al­go­rithm to mea­sure your pedal power and in­structs the 250W mo­tor to as­sist ac­cord­ingly when you’re not ped­al­ing.

Con­nect the wheel to the iPhone or An­droid app via Blue­tooth 4.0 and it gets even smarter, al­low­ing you to vary the level of elec­tronic as­sis­tance and track stats such as jour­ney time, dis­tance trav­elled and calo­ries burned. It takes four hours to charge the 48V lithium bat­tery for a 50km range, but it’s topped up ev­ery time you brake or soar down a hill with your limbs splayed. US$799, su per­pedes­trian.com, out spring 2014
