I was checking out the Mother Nature Network today and saw some very cool wooden bikes: http://www.mnn.com/green-tech/transportation/photos/11-awesome-bikes-made-of-wood. There is something sublime about a wooden bike. Wooden bikes bring up a good design point. To build a great bike, you need to really know what materials make up your ride, and take advantage of their strengths. In looking to design the perfect e-bike, weight is a constant concern. I think folks are making e-bikes waaay to heavy right now and I’m looking forward to making a nice light ebike.
