Zero X – The Zero emission totally green bike
There is no greener transport than the humble bicycle, add a motor to that and make it battery powered and you get Zero X. The American-made Zero X weighs 140 pounds, which weighs in about 100 pounds lighter than a typical 250 cc dirt bike. The Zero X is so small and light that it feels more like a big, electric mountain bike; it can hit 30 mph in just two seconds. Speed of the Zero X may not be as important to some as its silence. A casual trail ride on a pair of these bikes where riders can not only hear the sounds of the wilderness around them, but also carry on a conversation as they ride is completely unimaginable on a conventional motorbike. The bike is designed with aluminum rails that are easily removable, 40-pound, lithium-manganese spinal battery pack as the power source, which is claimed as can recharge in 2 hours for 2 hours of driving or a 40-mile range, depending on conditions. The unit is fully recyclable and can be swapped for another one in a mere 30 seconds. The 58-volt, 2.2 kwh pack is a proprietary design with 168 cylindrical cells, each with its own heat sync for cooling. The pack itself costs around $3000 and is built to last about six years, or 600 full-depth charging cycles.
The battery supplies power to a 17,400 watt, 23-hp electric motor, which is actually very similar to the units in many neighborhood electric vehicles (NEVs) Estimated to cost around $7450.
