I have been running IGH internally geared hubs for a few years and love them. They are reliable and there is no derailleur to get bumped or dirty.
Here is one Cool Cargo Grade IGH for eBikes.
https://support.enviolo.com/hc/en-u...enviolo-Cargo-internal-gear-hub-specification
100Nm, 500W nominal.
550 pounds of load. Bike + Rider + Cargo + Climb
380% Ratio
Dropout width 135mm – Not Boost.
Works with Veer Split Belt 9-Spline Cog for retrofit. https://www.veercycle.com/products/enviolo-rear-sprocket-replacement?variant=32446008492110
Multiply chain teeth to belt teeth by 1.59 to calculate Veer equivalence. Example a 45-t chainring = a 72-t Veer beltring. A 19-t cog = a 30-t Veer belt cog. At 90Rpm cadence this will give a speed of 10Mph in low gear and 33Mph in high gear.
Last night I put a half-link chain on one of my bikes that is as strong as a belt, but not as easy to keep clean. Zoom to see the wide chain.
