Currently my travel journal is a larger (5.25×8.25) moleskine, and I used an Xacto knife to carve out a TINY slot, just big enough for my fisher space pen “stowaway”, which is essentially the size of a refill, in the last 5mm’s of the pages.

I particularly liked your “test stand”. I have an old frame mounted on a trainer which is powered by a 1/4 hp electric motor driving through a number of v-belts and chains to the left side of the bottom bracket. On the right side the normal drive train operates. There is a fork mounted on a hinge which is attached to the seat post and carries the wheel with the generator hub. When it all gets going it is quite scary! I can definitely see that your system, at 30 mph, could be life threatening.

Thanks, Walter

Another thing the E6 E6z combo excels at is reach. My office is at the top of a 1200 ft mountain, which does not have lights on the road way. I often work late and as such I usually make the decent in pitch black. Here is where I have found the trapezoid pattern to be ideal. It reaches far better into the dark than any high power trail light I have tried before. Trail lights shine light evenly in all directions, including upwards. While this is good for trail riding, it is not an efficient use of light on the road.

As for the lack of spill light, at first I found it a little disconcerting when I would look to my left or right side and see darkness. However, at road bike speeds I would never head in such sharp direction, as such for my purposes the reflector design seems to put the light where I tend to needed it most.

That said, at slower trail speeds ( < 15 km/hr) with sharper turns the light pattern is restricting - it all depends on what you are doing. A helmet light, or a flood light may help in these situations, especially if you encounter these conditions rarely.

In the end it depends on what your needs are. The E6, E6 Z combo are a highly specialized to a particular kind of riding. If you ride on slower, twister roads you may consider a different primary light, one with more spread and shorter throw, saving the E6Z for the job as a secondary when speeds are higher.

Where did you get the momentary switches, rubber caps, and strain relief plug?

With the nFlex/momentary switch setup, do you need to turn the light back on once the wheel stops? (Yes, you’ve got me pondering the possibility of re-entering the dynahub world.)

Have you used them in strobe mode at all? I’m curious if you can get a very high frequency strobe (>=120 flashes/minute) with the nFlex.

Thanks,

I recommend leaving both lights at 1A. The hub is trying to produce constant current and the LEDs are more efficient at low current.

Since any ‘extra’ current is going to go through your shunt and get wasted I think you’re best off leaving both lights on the highest setting all the time.
