The stromerforum.ch Member 'S-driver' has used the Roxim Z4E Pro with the ST3 Pinion. Lupine SL MiniMax replaced. In the bottom bracket area, a 48 >12V Stepdown DC-DC converter to generate the 12 V supply voltage for the lamp with sufficient power (24 W). It also needs the SL MiniMax GoPro adapter to be able to mount the lamp in the Roxim holder. Alternatively, a Bluetooth remote control available.
Approval: for bicycles (e-bikes / pedelecs) according to §67 StVZO | Check digit ~K2258 but not for S-Pedelecs according to §50 StVZO (DE).
He writes analogously:
"The Lupine is fully functional. When I switch the bike on, the light comes on. Depending on the brightness, either with 2 watt daytime running light (200 lumens) or with 8 watt low beam (900 lumens). As soon as the low beam is on, you can activate the high beam with 22 W and 2100 lumens. A long press switches the light off. A short press switches between the modes. > Operating instructions
The lamp symbol on the wired remote control is off in daytime driving mode, green means low beam and blue means high beam. The high beam button on the Stromer has no function.
The supply voltage for the DC-DC converter can be taken directly from the main cables of the 48 V battery or the auxiliary tap (ST3 Pinion / ST5 only).
