3. Currently priced at $5,295.00 (with SLA batteries). Can upgrade to Lithium batteries "for an additional fee". And you can add the 'RYNO Rack" (to hold saddlebags) for $169.95.

It is just Amazing to see a new product design on the SLA Battery energy source, the low energy density and the very unstable voltage range must be a killer on the electrical circuit.
SLA running serial to provide higher voltage is also a huge potential problem, fundamentally it should be at least 48 or even 60 volts to be efficient for the running motor, otherwise the loss during conversion/switching phase to drive and control the motor would be very inefficient, running SLA just make the circuit design a nightmare to handle the high current and huge voltage drop under load.
The range of 10 miles, We all know a half of Segway's range is just a pain, and this is less then half.
SLA is dead cheap upfront investment however Li-ion isn't much more expensive nowadays, considering SLA will die within 300 full charge/recharge cycle (if you are extremely lucky), compare with LiFePO4's 1500+ cycle, also LiFePO4 is much safer chemical and environmentally friendly too
