SV-9 is ideally designed for rim brake.
Suitable for all different sized wheels! SV-9 got the approval from new German StVZO 6V1.5W LED regulation from wheel size 20” to 28“. However, its real output is much higher than 1.5W.
As for 6V3W, the German StVZO approved hubs in the current market normally offer 6V3W output when speed around 17km/h. SV-9 offers 6V3W output for 646mm(26”) and 716mm(28”) wheels when speed at 16.7km/h and 18.6km/h respectively. To match 6V3W output, does increasing speed only 1 or 2 km/h matter ? Only piece of cake.
