I own one of these and its great for short commutes.
I get lots of comment on how great it looks and its really easy to operate.
One word of caution. It is not an electric scooter the electric assist tops out around 20kph. I looked into this and some states have a 20MPH limit that would require licensing past that speed

As a commuter who relies on getting to work on time, while not showing up soaked in sweat, this bike has been a god send. The extra boost really helps you if you're traveling up hill or just at the end of your rope. It could stand to lose a few pounds, but it really gets the job done. And if you're traveling on the subway, the ability to fold and roll in compactly will blow you away. All in all a wonderful addition for this cycle enthusiast.

I purchased the DB0 at a local bike shop at a much higher price, wished i had hold a little longer for Amazon listing on the bike.
Having said that, its still a great bike and i commute it to and fro work of about 25km a day..the battery will last up to 40km on normal road but if you do not pedal on it all the time then its journey will shorten by maybe about 20-30%(batt life last longer if its constantly running/pedaling, dont ask me why), i have also tried to seek for modification if the speed can be increase higher than current 22-24km/h(not 25km/h really) but no bike shop can do that due to the batt is lithium polymor, they claimed its not possible to add extra batt like other lith-ion can.
All in all still a beautiful bike to be on but sucks when another old-looking eletric bike cruises by effortlessly.
At the price its going now, get it if you can afford.

PS: The bike frame is manufactured by Ducati, just FYI.
