If you’re an advocate for public transport and car pooling over a one-driver-one-car policy, then you’ll definitely love the eROCKIT electric-assist bike. This human-hybrid machine will use the cyclist’s pedaling motions to get the motor going, which in turn will multiply the rider’s effort by 50 times – this means the faster you move those legs and start to sweat furiously, the faster you will be able to go. The nano-phosphate lithium battery used has a life expectancy of 10 years or 50,000km of use, whichever comes first. The eROCKIT is able to hit 50mph at full stride, and a maximum charge ought to keep it moving anywhere from 60km to 80km, depending on the terrain travesed. The only drawback? Manufacturer RockiT wants to release just 10 of these machines next year for a jaw dropping $44,000 apiece.
