Burned up my Altrax 4834 after 500 miles due to
no heat sink and hot rodding and most likely not
letting pre-charge resistor do it's job when
starting it up.

("Kill a Watt" recharging measurements .72 kwh
/ 13.7 miles = 53 Wh-r/mile).

It is pulling 15-16 amps on flat and steady at
28mph with Dustbin + Red Fairing on top in
fully tucked riding position.

Additional FeaturesGrin Tech LED headlight running on traction battery voltage.

Ammo Boxes hold/protect batteries.

12 Gage Solid Strand cooper wire twisted on throttle to be throttle

Rear wheel reversed to allow running up to 72 volts on PERM-132
(recommended rotation direction) motor. Currently running 48 volts
in 2016-2018.

Chain tensioner is an old roller skate wheel.

Running one (1) heavy duty shock/spring on rear instead of 2
lightly sprung shocks. Leaves more room for chain with large
diameter sprocket and is lighter.

Jan. 2018: Update misc. items to reflect current configuration
with Chevy Volt Batteries.

Jan 2017: Update total miles to 6046. It now has more electric
miles on it than it had gas miles on it when it went to the
junkyard in 2007.

September 2015: 2kWh chunk of a Chevy Volt Battery put into two 50
caliber ammo cans and mounted on bike. Running 42-48Volts. Range
is 22 miles.

December 2012 Update: Added Picture of bike with July 2012
Modifications: back to original front wheel with disk brakes,
front and rear brakes on handlebars, original handlebars, upgraded
to 72 volts. Bike is very fun in this configuration. Geared for
45mph max speed, this bike wheelies on take off and would climb a
tree if it had spiked tires.

November 2009 Update: Updated Mileage - I've rode 800 miles since
installing the dustbin fairing this year.

My batteries have been weak all this Summer due to my running them
to 80-100% Depth of Discharge for the previous 2 years. This
really cut into my miles as I was limited to riding 14 miles each
way. Plan to purchase some new batteries for the 2010 season -
hopefully something better than Lead...

August 2009 Update:
- Added recent picture with new vintage tail piece

June 2009 Updates:
-Updated power usage chart for up to 60mph.

May 2009 Updates:
-Updated instrumentation information

-Removed picture of throttle lock

-Added picture of dustbin with extra red fairing on top

-Added Picture showing Watts used vs. Velocity chart

April 2009 Updates:
-Added info on WHr/Mile with Dustbin.

-New Picture of Dustbin with signage.

-Added 0-32mph acceleration times.

-Updated Vehicle weight with Dustbin fairing.

March 2009 Updates:

-Added picture of dustbin fairing on bike.

-Added diagram for measuring voltage and amps with one VOM.

August 2008 Updates:

Added pictures of throttle lock.

Using Kill-A-Watt P3 meter to measure actual cost of recharge from
120V outlet. It only weighs 5oz and is nice way to verify actual
energy consumption when charging. Added data related to recharge
time, cost, etc. to my website.

July 2008 Update: Updated information on PERM-132 brush
maintenance. See link below for updated information on brush
