While not to market yet bafang has a robust and smooth automatic igh

[cloakedvillain]

The shifting is electric and based off of wheel speed so it would need a small battery but if you have lights on your bike its just as much trouble. They claim an 80nm max continuous torque which is a lot for an igh and appeals to clydesdale riders. (tall guys that love to stomp or "crunch" as they say on the pedals)
Three speed for mountain bikes(any bike with 135 drop outs but most common on mtb bikes, hybrid bikes and city bikes with rear derailleurs)

This doesn't give enough information on the controller. With the LandRider it had a cadence adjustment screw. This allowed me to adjust what speeds the bike shifted at. Otherwise it would've been in the top gear around 15 mph.

I hope the controller allows you to set what speed the hub changes gears.

Yeah as they're still tooling for production we don't have good info other than dimensions and ratios.

They did have information on both the 3 and 5-speed ratios. What you want with a motorized bike is for a higher minimum/maximum speed for a gear before it'll shift either down or up.

Any specs on how much torque it can handle, there are several "geared hubs" that shift automatically but are limited on torque.

Press releases say 80nm continuous

So that is inline with the Enviolo which is a constant variable drive and good for about 3/4 hp max. Good enough for a mid power edrive but a little low for a gas motor.
