Unlike other similar products coming to market... Superpedestrian's unit (which slots on to your back wheel) is not about powering up continually to save yourlazy legs. A series of sensors are embedded in the red casing, which track your speed, incline, pedal-pushing prowess and other factors, in order to calculate when you need the power most. As such, the battery-powered 5.5kg pack will save energy, while also recharging every time you brake, powering up to speeds of 32km/h with a range of 48km.Interesting video - and not a "concept." This device is commercially available via Superpedestrian. Too bad it costs $700.
