E-Bike System

[mistercrash]

That thing looks cool. But it starts at $5500. A little too much for me. I'm moving forward with my plan to go ''gasless'' in the near future. We have two cars, a 2007 Toyota Rav4 and a 2004 Toyota Sienna. My work is 2 minutes away from home so we really don't need two cars. So the plan is to get rid of the wife's Rav4 first, it's not that bad on gas but it's suspension is hard and the seats are not comfortable. We traded it in for a fully loaded 2007 Mazda6 GT wagon. About the same gas mileage as the Rav4, maybe a tad more but the ride is much more enjoyable. This car is temporary anyway, we don't plan to keep it more than three years. Hopefully just two. Then we want to sell my Sienna and replace with an electric bike. We are interested in electric cars that are hitting the market and the Chevy Volt looks cool. But it's a brand new model so we thought, let's drive the new Mazda a couple years and let GM fix the bugs out of the Volt and in two years, start shopping for one to replace the Mazda.
So now I need to sell the minivan to get the E-Bike. I am still debating if I go with something that is ready to go like this or a system I can incorporate to a bike of my choice like this.
