Planetary drive systems are pretty cool. They are simple in concept but complicated mechanically. They are a little on the expensive side.
This drive can provide a wider range of gear ratios than the standard 3-ring crank. Shifting is done by a silver button on the axle. It’s a great way to learn shifting without the complications of a front derailleur.
If you are thinking or are not familiar with them you can try it at Palmer Lake.
It’s available for demonstration. Feel free to send me a message.
