Title: Doug's bike light for commuter bike
Post by: six el six on May 15, 2012, 10:13:21 pm
I've been thinking about getting one and i wanted to know the best way to mount the battery pack.

On one of the videos it says the wires from the pack to the light shouldn't move. How is that going to be possible? I mean if the battery pack is mounted on the bike frame the wires will lead to the bike light  on the handle bars and that will most definitely move.

So, yeah, how should I mount the battery pack? On my handle bars? With what sort of device should I mount it with?

The wires can move, the video is showing that you do not want the wire to bend back and forth at the connectors at a hard angle.

Just as in any wire connection, the wires will break if you do that too much

I mount my batteries 3 ways

In a back pack if it's on my helmet
Inside a chooped up water bottle and then in the water bottle cage
Inside a pouch that is velcro'd to the top frame tube

The light works great! Excellent for safety.

 IT'S SO BRIGHT I HAVE TO SAY SO IN CAPS!

The cord is long enough to fit the battery pack in the front pocket of one of my rear panniers and I use zip ties to fasten the cord to the frame keeping it out of my way.

Thanks Doug!

Glad you like it
Have you got the hang of tapping the switch lightly to change modes?

Yes. Works nicely but I'll almost always use it on the highest setting. I live in a city with none too bicycle friendly motorists and I got the light to let people driving automobiles around me know that I am there.

 It's the brightest bike light I've ever had.

Now all I need is a train horn and I'm set! :icon_biggrin:

Cars may flash their brights at you if you have it pointed up a bit

That's a good thing, IMO  :icon_biggrin:
