SON XS DYNAMO HUB
There’s no better company in the world to produce hub dynamos. The SON heavy-duty dynamo has a minimum resistance and a high power output. If you are not using lights, it will slow you down by just 0,1 km/h at 30 km/h. This value will be 0,7 km/h if under load. And this is quite negligible. Thus, you can safely charge or use your lights all day.
We usually mount this dynamo on the left side of the trike. And don’t worry, your trike will still go straight even with the dynamo attached.
TIP: Only for disc brakes
