That reminds me... I need to open up my generator, clean it up, and relube it.

I give a lot of credit to the person or persons that would attempt to commute 2 hours (30-40miles or more) each way. Chances are that they would be commuting in the dark in both directions, which would mean having more battery capacity than 2 hours and recharging abilities at both work and home. And the lights would have to be pretty bright for the speeds over 20mph. I use a Nighthawk Dual Pro 10w/20w halogen headlight and find that the 10w is insufficient at the speeds I travel, even with the single 20w light I still occasionally miss seeing potholes and road irregulaties. Using the 20w only give me 1hour which is more than enough time for my 13 mile commute home, wish I had more battery capacity and lighting power. If I run the full 30watts I'd be cutting it close with the battery (supposedly 35 minutes at 30 watts) for my commute.

I agree kgatwork, a 2 hour commute would really tax any kind of lighting system. Just the stress of riding in traffic for that long in the dark would do me in.

My night time commute is about and hour and a half. I have a red blinkie at the back and a Cateye EL300 and a white blinkie at the front. The main benefit of these is that I dont have to worry about when the batteries will run out. Most of my commute is with decent street lights, but I am planning on buying a Panetbike light to mount on my forks so I can maintain a better speed when away from the street lights.

About half of my 26 mile commute is semi rural..WIde shoulders..Two batteries. THink it do able...Sort of in a mood to just give it a try and see how it feels.

AndrewP-- I think a fork mounted light might really be good. It's tough to watch for potholes and cars at the same time. It's not only the amount of light your system puts out, but where that is

I think a fork mounted light, being low down and at a fine angle to the road, will spread the small beam over a longer distance in front. If it works OK I might then get a second fork mounted light for the other side. Also I have run out of mounting space on the bars.
