JetBlack's intro trainer is about as simple as it gets, but it’s good enough if it’s all you can afford. The simple rectangular-section steel frame, metal roller, magnetic resistance engine and small flywheel come assembled, which is a get-on-and-go bonus.

The frame itself is reasonably stable too. There’s masses of flex across the rear axle though, so don’t twist your bike about too much to get your torque out. The small flywheel means it picks up speed fast, with no wheel slip. And there’s enough resistance to get you sweating with a compact chainset.

There’s absolutely no momentum or run-on though, so it feels choppy when you’re pedaling. It’s loud too, and with lots of numbing buzz through the saddle it’s best for short intervals rather than long sit-and-spin sessions.

Guy started filling his brain with cycle stats and steaming up bike shop windows back in 1980. He worked the other side of those windows from '89 while getting a degree in “describing broken things covered in mud" (archaeology). Dug historical holes in the ground through the early '90s, then became a pro bike tester in '97. Guy has ridden thousands of bikes and even more components the world over since then and can remember them all in vivid, haunting detail. Can't remember where the car keys are, though.
