Donna’s a Catrike rider. Now, Jon’s joining her with a matching Eon Green 559.

Catrike’s stock 3×10 gearing (3 chainrings/front and 10 cogs/rear) offers a whopping 568% gearing range -perfect for both fast downhills and slogging uphills.   So far, so good!

Until next year, that is, when both Donna and Jon are moving to single chainring motor kits.  Out the window goes almost a third of that 568%  

The solution? A 3×3 Nine Hub!  Its 550% gear range nearly matches Catrike’s stock 568% range.  So, even with the motor off, Donna and Jon will still be able to speed down and slog up!
