HeaterWarm thoughts
DC/DC Converter Green Galaxy
Only puts out 10A, but I run LED lights.
My usual draw is under 500mA, so 10A is more
than needed. Very small and lightweight, but
non-isolated.

Update: I've ridden over 2300 miles now
(3700km) and it still rides like new.
Absolutely love it. Great commuter too.

Depending on riding style, range is still
typically 30-35mi (48-56km). But, much of
my riding is commuting (25-50mph). In the
city, my watt/hr/mi is often in the low
70s. Light weight really helps efficiency
in stop and go.

I've added pictures of some offroad riding
in the Colorado mountains. Throttle and
torque are more responsive than gas bikes
I've ridden. Can literally leap out of
whoop-de-doos with a twist.

I did have to make the rear rack stronger,
but now I can even jump the bike (not
anything big of course).

Hikers actually approach me when riding to
talk...with a smile.
