Overview
The JOROTO X4S is a magnetic resistance stationary bike with a 40 lb flywheel, a digital monitor for speed, distance, calories, RPM and heart rate, and a steel frame rated for riders up to 350 lbs.
Riders coming from studio classes tend to compare it directly to a Peloton, and several say the top resistance setting lands around 70 percent of a Peloton's hardest level, still enough for a real sweat. The bike pairs with its own JOROTO app plus Zwift and Kinomap over Bluetooth, though the connection goes from bike to app directly rather than through the phone's Bluetooth settings, which trips up some first-time users.
- 40 lb flywheel with 0-100% magnetic resistance
- Digital monitor tracks speed, distance, calories, RPM, heart rate
- Steel frame supports riders up to 350 lbs
- Pairs with JOROTO app, Zwift, and Kinomap
Who it's for
Best for people replacing a gym spin class at home who want adjustable resistance and app connectivity without a subscription-locked ecosystem. Riders wanting a plush, contoured saddle out of the box should plan on budgeting for a gel seat cover.
Pros and cons
- Resistance tops out at a genuinely hard setting
- Runs quiet enough for shared walls
- Frame feels stable under sustained hard pedaling
- Assembles in under an hour
- Stock seat is hard and narrow
- Bluetooth pairing goes to the app, not the phone
- One reported unit undercounted total distance
Performance notes
Noise stays low enough for apartment use since there's no belt or brake pad friction to manage. The onboard computer reads out speed, distance, calories, RPM and heart rate in real time and pairs directly with Zwift or Kinomap over Bluetooth for guided rides.
