The lighting system is somewhat disappointing. The Shutter Precision SD-8 hub dynamo is designed for small wheels with high rotational speed, and is small, light, and efficient. The Supernova E3 Pure 3 gives good light but
doesn't have an off switch. The power drain from always riding with lights on is small, and there are safety benefits even in full daylight, but the rider should make that choice. I could make my own light switch solution, but it's hard to get that properly sealed against water. I may replace the E3 with something better, perhaps the Busch + Müller IQ-XS. Secondly, the way it's mounted it shines on the front carrier, leaving a shadow on the road ahead. It may be hard to find a better spot for it that doesn't leave it vulnerable when the bike is folded, but I'll have to try. Third, it throws no light straight to the sides, for being seen in that direction. It's got good looks but poor functionality.

The Supernova E3 taillight is bright but tiny, and mounted on the brake caliper where it is easily obscured by the wheel. It's completely unnecessary to use such a quirky minimalist solution when the bike has a rack with a standard light mount and a big flat reflector on it. I'll probably put a decent sized taillight/reflector combination there instead.

Still, no regrets. The important thing was to have the dynamo wheel in place, lights are easy to swap out. I just wish R&M would have more focus on functionality here and less on stylish looks and minimal weight.
