Getting a charge: An exercise bike that turns your pedaling into power

I enjoy getting my exercise, but hate doing it indoors. I'd much rather get some fresh air and watch the world drift past me as I cycle or hike somewhere than watch a screen while sweating away on something stationary.

To get a bit more of what I like, I've invested in a variety of gear that has extended my cycling season deeper into the winter. But even with that, there are various conditions—near-freezing temperatures, heavy rains, Canada catching fire—that have kept me off the roads. So, a backup exercise plan has always been on my to-do list.

The company LifeSpan offers exercise equipment that fits well into a home office and gave me the chance to try its Ampera model. It's a stationary bike that tucks nicely under a standing desk and has a distinct twist: You can pedal to power the laptop you're working on. Overall, the hardware is well-designed, but some glitches, software issues, and design decisions keep it from living up to its potential.
