Welcome to the A2B Metro- a revolutionary design in electric two-wheel transportation that's redefining the way we go places.  Take the A2B Metro for a spin and feel the freedom of being able to get exercise while just pedaling,  or adding a little motor assist, or cruising along using the motor alone- thanks to its "power on demand" acceleration.  The choice is yours.  And when you outfit your Metro with a range of smartly  designed Ultra Motor Commuting Accessories like a laptop commuter case, grocery carrier panniers & other bags, front or rear basket, etc. you'll turn those daily errands into a JOY RIDE!  A reliable workhorse, with a powerful 500 watt hub motor & lithium battery built into the frame.  Add a secondary battery (shown in photo & sold separately) which attaches  beneath the rear rack and you'll double your distance from 20 miles to a 40 mile range  with the combined batteries.
