Hub drive for spoke rims
The Pendix eDrive IN product line includes a 70 Nm hub drive, which can be combined with various vehicle types, drive
trains and rim versions. Building on numerous years of experience in which the motor concept has already been used
in the Pendix eDrive, the Pendix eDrive IN offers the necessary reliability for daily use under tough conditions, e.g. in a
cargo bike on the last mile.
When using spoke rims, the detachable spoke ring of the Pendix eDrive IN offers great advantages. This means that
the spoking in production can be carried out completely without a motor. For servicing, the motor can be removed
individually while the spoke ring remains in the rim.

Innovative or classical drive solutions
Technical data for 2 example configurations
Power transmission from the rider to the wheel is becoming increasingly complex in modern cargo bikes and other
novel micro-mobility vehicles. Therefore, the Pendix eDrive IN is not only offered as a version for mechanical drive
trains, such as the chain or belt drive, but also as the innovative serial hybrid variant Pendix eDrive INs. Below you
can compare the advantages of both versions.

Components for individual system configuration
To meet the specific requirements on the vehicle, the Pendix eDrive IN system offers a high degree of flexibility.
Whether rim type, battery or sensors - in addition to the already specified components, customer-specific wishes
can also be fulfilled and third-party components can be integrated into the system.
Pendix disc wheel
Due to the effect of increased loads, a spoke wheel is not always optimally suited. For this reason, Pendix offers a
heavy-duty disc rim designed for use with the Pendix eDrive IN. The disc rim is available with or without tires.
