PIAGGIO not currently produces or market electric bicycles, like pedal assisted one (EPAC), as this ALBATROS (in photo) or other types.
A model is well known: ALBATROS, of which are still on selling various markets (including ebay) with prices around € 500. Adopt a motor positioned in the front wheel and a battery with low performances heavy compared to today’s Lithium.
I think it did not even have gears to change, something very useful to use full power of the electric motor. This one was not huge, but if well used could do better.
HERE you can find other Albatros photos.
