Additional FeaturesCruise control with brake lever deactivation from Electric Rider,

LED Headlight from GRIN plugs into Cycle Analyst

Widened a springer fork to hold rear wheel motor hub - adds
suspension to ride makes it handle bumps nicely
Sept, 2015 - Back to Ape Hanger handle bars. Put batteries in tool
bag. Purchased Grin Satiator charger to charge batteries more

July 27, 2014 - Added pictures of bike with underseat steering and
batteries in trailer. Wh/Mile increased, trailer makes bike too

June 16, 2013 - Updated Wh/Mile, Range information.

I absolutely love the cruise control feature. You turn on the cruise
control and then use the + or - button to tune in the speed/power you
want. The cruise control takes care of the motor, I can concentrate
on pedaling and enjoying the ride.
