Purpose
The Extreme hub is rated for use in a system with a maximum mass of 250 kg when paired with a 90 Nm motor. The Heavy Duty [HD] hub is rated for use in a system with a maximum mass of 160 kg when paired with a 90 Nm motor. Enviolo's technical manual is linked for reference.
Scope
This upgrade is relevant for customers with the Triobike Taxi equipped with:
- Brose mid-drive motor; and,
- Enviolo Heavy Duty [HD] hub; and,
- Gates belt-drive.
The upgrade may be fitted independently, or requested if you are returning to Enviolo under warranty a faulty Heavy Duty hub. In the latter case, Enviolo will ask you to pay the difference in price between Heavy Duty and Extreme hubs. In both cases, you will also need to purchase the items listed under the Extreme hub, below, available from Copenhagen Cycles as a kit.
