that looks like a really nice and practical bike, and half the price of a Specialized Turbo! :-)
I always wonder about those top speed claims. They usually seem to be no load speeds, meaning the cruising speed of the bike is about 15% lower than that.
I built a bike kinda like that, with a hub motor though. Top speed (i.e. no load speed) is 29mph, cruised to work on it at 25mph today. Home built bike cost about $600 (actually cost me about $200 since I am sharing the battery from another bike).
Still, that seems like a pretty practical bike. I like the battery, and the mid drive mated to a decent mountain bike frame. They have kept the weight down low.
The one big problem: 28mph with 48v8.7Ah is going to give you a pretty limited range.
