You can do better then $2,000 and get a very good set-up, keep looking there are many options. Yes, ebikes are heavy. Beside the obvious, the weight of the motor and battery, the bikes are generally designed to be structurally strong = weight.
It's a fantastic bike -- so I thought, why not just add a BionX S350 DV to it -- so I look up the price and it's over $2000! (the Giant was $1000 after taxes). Is the motor so good that it's worth $2000 by itself? .
