You mentioned front weight of the bike. The front to rear weight percentages is reversed on a Cruzbike. My new Q-45 has the seat pan forward and the back angle about 50 degrees. Sitting in my riding position, I am 60%/40% front/rear. I was just curious to compare to a diamond frame bike.
If I may, I believe the comment about front weight is comparing the steering input required between a diamond frame / rear wheel drive recumbent to Cruzbike / moving bottom bracket steering input.
The difference is significant because the torque required to steer a diamond frame is based on weights and distances from steering axis of handlebar, stem, fork, and front wheel. Cruzbike adds the bottom bracket, cranks, and chain ring(s), and to a lesser degree the chain stays and boom to the equation. So the forces required are greater with the Cruzbike and the momentums are also greater.
The inputs are not significant enough to cause any difficulties once you are moving or once you are used to them but they do take a little while to get used to when learning especially at very low speeds and are different from what you expect on a bike that doesn’t have gearing on the front wheel.
