Complete drive systems

from one single source

HEINZMANN DirectPower series bicycle drives can be used in different systems thanks to the independent control integrated into the battery box. The power electronics are located outside the motor. This means that they are not impaired by any motor heating, ensuring that the system performance is not reduced.

The regenerative system can recharge when travelling downhill and when braking, which can increase the range. Whether they prefer a front or rear wheel drive, the DirectPower system adapts to our customers’ specifications. Thanks to this flexibility, it has a variety of possible applications in addition to the e-bike market, mobility scooters being just one example.

The external control for the DirectPower system is normally integrated into the battery box . This can be a luggage carrying system or a down tube system. It conveniently controls all the drive functions. Support is activated and the level of support is selected using a torque sensor in the bottom bracket.

Various parameters such as assisted pull-away and support levels can be adjusted by the customer using a control unit on the handlebars. The control also allows regeneration.

The operating software can be updated by the OEM via an interface. A wireless connection via Bluetooth is possible.

Down tube batteryDown tube batteryCarrier battery

The lithium ion high-performance battery with integrated control is available in two different designs: for attachment to the down tube of the frame or to the luggage carrier. Thanks to magnetic plug connections it fits quickly and easily into the holder on the housing box.

A separate charging socket allows the battery to be charged separately from the bike and the charge level can be displayed at the push of a button. Passive cell balancing increases the service life of the battery pack, which is water-tight, shock proof and vibration-resistant.
