Do not worry. GreatEbike team is in full operations even during the Corona Virus crisis in EU.
The German brand BOSCH is a trademark of quality and this is confirmed by its central motors for e-bikes. The level of reliability is almost 100%. In 2013, BOSCH came up with the first generation central drive, which de facto started the era of central drives for e-bikes. We have all 3 series of Bosch mid drives - Active Line, Performance Line and Performance Line CX. The high price level is well balanced by the quality of production and these drives are characterised by the lowest failure rate of the entire range.
