Great looking ebike, but even though I my daily rider is crazy fast, 100mph+, I wouldn't want to ride this A2B at 50. It's simply not set up for speed and the shortcomings are obvious in the ride video when taking it through curves. The things that combine for this result are:
1. Geometry- Especially with a small front tire that naturally shortens the trail, the steering geometry is made for low speed sensitivity and stability.
2. Seat/frame type- A "sit on" arrangement as opposed to a typical bike with a frame that you clamp between your thighs results in a scooter type ride with the bike having more lateral movement under under you. The rider/bike carving the curves in unison is more forced instead of coming naturally.
3. Battery high in the rear- Convenience and looks overcame handling concerns for these mods, since high in the rear results in wag-the-dog behavior. Another reason I always avoid rear rack batteries is mounting significant weight up high makes a bike less stable when parked.

I've always liked the looks of the A2B. If I get my hands on one I'll have to do something to give it more trail...some combination of rear shock selection/mounting, a larger front wheel, and/or longer forks.
