ICE Trikes now have the longer axle version in stock to fit their trikes. Even front suspension models.
Both the 70mm X-SDD and the 90mm XL-SDD drum brake version's.

Re: Sturmey Archer Dynamo Hub
I’ve got a 70mm dynamo on an ICE trike with a Busche Muller front and rear light with a Sine Weave USB charger it was set up for me by Bike Fix. The lights work really well the charger not so well. I think the charger is let down by me the rider not the charger. My average speed is around 8 - 9 mph not really fast enough to charge anything. I’m just trying out a Zendure 6000 battery to see if I can trickle charge that and use that to charge my gadgets.
