- Is easy to operate and maintain. Insert your key, twist the throttle, and you're off! The battery pack never needs
to be removed, and charges from a standard wall outlet (with included charger). The bike is maintained exactly like any
other bicycle. You never need to worry about the electrical system - leave that to us.
- Is serviced and sold exclusively through UltraMotor Seattle. On the rare chance that your Portia somehow breaks,
never fear! Our two-year warranty and trained staff will have you back on the road in no time - at no cost to you!
- Is tested prior to every shipment, and assembled and checked prior to every sale. You don't get a box of parts, you
get a bike!
- Uses a Lead-Acid battery, the gold standard for light electric vehicles. Low cost and high capacity = maximum range
in an expensive package.
