Here are my subjective thoughts on these questions:1. How would you guys characterise the bikes capacity to be used as an exercise bike?
2. Is riding without the motor just not realistic?
3. If not, is riding on eco 1 give you decent level of exercise?
4. If no to all, then would it be fair to say that bulk of the use with the new motor is for commuting and touring?
1. Regarding this study, and my own personal experience the UC is without a doubt an exercise bike. Even though I'm on an ebike, I'm outside and getting exercise. One part of the summation of the study is, "...this data suggests that e-bike use leads to substantial increases in physical activity in ebikers switching from private motorized vehicle and public transport, while net losses in physical activity in e-bikers switching from cycling were much less due to increases in overall travel distance."
2. No, I don't think so. Whether you ride for desired extra effort, or the battery is drained, an ebike can be ridden without a motor.
3. Yes. I may have to provide less effort, but I'm staying out longer, and I'm still pedaling.
4. I guess this question is "NA" since I didn't have a "no" to any question. If the goal is to increase the effort on an Ultimate Commuter so it's closer to a regular bicycle, I imagine creating a profile to limit the assist would be a good way to go.
