Typical amusing translation from Babel Fish:
The eROCKIT Bike combines the operation of a bicycle, i.e. step accelerating by strengthened into the pedals, with the road performances of a motorcycle. The electric motor provides for a high acceleration and maximum speed of 80 km/h.
“The healthy and refreshing total body employment of the wheel driving is combined with the driving dynamics of a motorcycle.†- so the manufacturer.
The range of the vehicle amounts to dependent, on style of driving and on the distance condition, 60 to 80 kilometers. Subsequently, the batteries, at a usual 220-V-Steckdose, must be loaded again. A loading procedure is final in three to four hours
eROCKIT is series hybrid: To progressive movement humans steer the number of revolutions of an electric motor by a crank gear and an inserted generator. The generator registers the rotation of the crank gear and sends according to the footstep frequency an output signal to control electronics. , The faster turns 8 KW strong direct current brush engine is the faster stepped.
The generator, which takes up the rotation of the crank gear, is a permanent magnet generator and recovers at the same time the footstep energy, which is then used for the reloading of the batteries.
The energy storage eROCKITs consists of lithium ion nano-phosphate batteries, which are characterised by thermal stability, high power density and long life span out. The batteries with an overall capacity of 2,9 KW/H are accommodated in a carbon fiber kevlar box.
A battery management system supervised permanently the conditions of the accumulators and provides for its optimal enterprise. This happens both when driving and in the switched off condition of the vehicle. By a load reconciliation between the individual battery cells the battery management system increases the life span of the batteries and maximises the range.
eROCKIT under Germany as light motorcycle and receives an European Union width road permission is classified. The vehicle is thus characteristic and driving licence requiring (in Germany the motorcycle driving licence class A1 necessarily).
The maximum speed of 80 km/h gives eROCKIT free trip also on motorways.
