They will conquer the markets much faster than e-cars: Electric bikes are already a growth market. Automotive supplier Robert Bosch GmbH announced its collaboration with bike vendor Cannondale in this segment.
In order to serve Cannondale and later also other clients in this market, Bosch has launched its new business unit Powertrain Systems eBike. The company said the unit will develop and sell modular powertrains for electric two-wheelers. First ebike models equipped with the system are expected to hit the market later in the year; the companies plan to present the a model with a Bosch powertrain during the Eurobike trade show in early September.
The Bosch ebike powertrain embraces the drive unit with sensors, a lithium-ion battery pack along with a charger and a control computer on the handlebar. The computer does not only calculate the force for the motor at any given situation but also represents the Human-Machine Interface (HMI) for the ebike.
The three sensors measure pedaling force, pedaling frequency and speed of travel. Based on these input data the computer determines the energy required to support the driver after all, the ebike concept emanates from the assumption that the user continues to use its own physical forces to propel; the electric motor has only a supporting function, improving the comfort experience for the driver.
Over the past months, an increasing number of ebikes have already arrived at the markets. In April, market researcher Frost & Sullivan published a study predicting steeply rising sales figures for this class of vehicles.
