Sparta Launching Brand for Accell Group’s Mid-Motor


APELDOORN, the Netherlands – “We did not want just another mid-motor, but a product with its own riding characteristics that could add value to our e-bikes,” said Sparta’s commercial director Mark Kuper about the new ION mid-motor. As the innovative e-bike brand of the Accell Group, Sparta will launch the new developed mid-motor in their MY 2016 range.

In 2003 Sparta initiated the e-bike boom in the Netherlands which also contributed to the growing popularity in onther countries. Since that start more than half a million e-bikes (including the ones of other Accell brands) with the in-house developed ION drive train system have been sold.

For their mid-motor Sparta wanted to create a new drive system with the lowest possible noise levels in combination with outstanding drivability characteristics.

Noise level: important issue

Due to internal gears mid-motors will always generate more noise than the direct-drive front or rear wheel motors. But market research showed that the noise level is an important issue for people riding e-bikes recreationally. Therefore Sparta invested heavily in test equipment in order to reduce the noise level to a minimum.

Kuper, “The result is that we have developed a special motor cover; that we adapted the frame design; the mounting of the motor as well as the connection between the motor and the chain guard. Also adjusting various parts inside the motor proved to be essential.”

“The same goes for the ION software which has been set differently. All this just to reduce the level of noise.” According to the Accell director the result is a mid-motor drive system that is fit to carry the ION legacy further.
