Overview
This DMASUN exercise bike pairs a 35 lb magnetic flywheel with a 330 lb weight rating, plus anti-loosening pedal nuts and a padded seat cover added to address the two most common complaints on bikes like this.
Resistance runs on a magnetic system rated under 20dB, and the console lets a Wahoo sensor pick up RPM from the crank if you want that data outside the bike's own display.
- 35 lb flywheel rated to 330 lbs
- Magnetic resistance under 20dB
- Compatible with Wahoo RPM sensors and SPD pedals
- Fits riders from about 4.8 to 6.1 feet tall
Who it's for
Fits home riders who want a stable, quiet bike for daily indoor cycling and do not need a screen based training program built in. Shorter or older riders who need the handlebars angled back toward them should weigh that against reach, since one reviewer flagged it as a limitation.
Pros and cons
- Handlebars do not tilt back, an awkward reach for some shorter riders
- Resistance is manual, no app-driven programs
Performance notes
The 35 lb flywheel and magnetic brake give a resistance range described as running from a light warm up band up to a harder muscle building band, adjusted by hand rather than motorized presets. The display tracks time, speed, distance and calories and resets with a long press; RPM can also be picked up by a Wahoo sensor at the crank for riders who log data elsewhere.
