Micro-USB, unfortunately.

It's getting darker earlier here in the PNW and I bought one of these last week for use with my new RadMini. I really like it as a helmet (fits well, handsome look) and the lights help me feel more visible. When I drive I'm really aware how much helmet lights help me spot bicyclists. I'm even turning on the bike & helmet lights during the day. Every little bit helps. Recharges easily via USB. When it's really dark the front light acts as a second headlight, not super bright but helpful nonetheless.

My brakes also squeaked and I ended up getting them tuned at my LBC. I bullied Rad into paying for the service. Now they work great. My bike mechanic said that basically no one should assemble their own bike because the final tune on breaks/gears/wheels is often fussy and requires quite a bit of expertise to get right, and I'm a little annoyed with Rad for not setting expectations accordingly.

After the first week I had an increasingly squeaky rear wheel. It was the spokes. So I got a 12 gauge spoke wrench and (after realizing that you tighten by turning COUNTER clockwise) tightened the loose spokes without throwing the wheel out of true. Now it is nice and tight! Strongly recommend paying the extra $$$ for the SW-3 Park Tool wrench, I've already gotten a lot of use out of mine.
