Coospo S10 Power Meter Review // Another Gamble at JUST $88?
Shane Miller - GPLama
5 de marzo de 2026
A few weeks ago the ThinkRider PP5 became the cheapest spider power meter I’d ever tested at around $100. Unfortunately it failed due to residual torque issues that caused inflated power readings after hard efforts. Now the spotlight shifts to the even cheaper Coospo S10 at just AU$123 (about $88 USD). On paper it’s almost identical to the PP5, claiming ±1% accuracy and the same core specs. But after giving it every opportunity to succeed across multiple tests and reference meters, the results told a familiar story - inconsistent behaviour and accuracy that simply didn’t meet its own published specifications.

Creado: 29 de marzo de 2026The reviewer conducts a detailed test of the COOSPO S10 Spider Bike Power Meter. They state it is very cheap, costing around $88 US, and is similar in almost every way to the Think Rider PP5, which they previously tested and found to be flawed. The reviewer's testing reveals significant issues with accuracy and consistency. Specifically, after hard efforts or sprints, the power meter exhibits 'residual torque,' where it does not return to the correct zero point, resulting in inflated power readings until it is manually zeroed or calibrated. This behavior was observed repeatedly in indoor and outdoor tests against multiple baseline power meters (Assioma Pro, Garmin Rally RS210, trainer power). The reviewer notes the unit has a firmware update process similar to the Think Rider, a slight lag in data reporting, and that its published specifications (e.g., +/-1% accuracy) are not met. They conclude that while it is inexpensive and sometimes reads correctly during steady-state efforts, its performance degrades under load, making it unreliable and not something they would recommend or use themselves.
Resumen IA
Pros
- Very low cost (approximately $88 US).
- Reads accurately during steady-state, non-sprinting efforts (when not affected by residual torque).
- Lightweight (noted as being 8g lighter than the similar Think Rider PP5).
Cons
- Inaccurate and inconsistent; fails to meet its own published specifications (e.g., +/-1% accuracy).
- Exhibits 'residual torque' after hard efforts, causing inflated power readings that do not self-correct.
- Requires frequent manual zeroing/calibration to maintain any semblance of accuracy.
- Has a noticeable lag in data reporting compared to other power meters.
- Firmware update process (to v1.72) caused the unit to report 0% battery and required a full charge.
- Significantly increases in total cost as it requires a separate crankset and chainrings.
- Performance is unreliable for any riding involving sprints or hard efforts.
- The reviewer suspects it is a white-label product, similar to other problematic meters on the market.
Key Points
- Model: COOSPO S10 Spider Bike Power Meter.
- Price: ~$123 AUD / ~$88 US.
- Interface: Requires a crankset with the Easton Cinch interface.
- Weight: 8g lighter than the Think Rider PP5.
- Firmware: Shipped with v1.68, updated to v1.72.
- App: Uses a separate 'CUSPO tools' app for configuration.
- Accuracy Claim: Advertised as +/-1%, which the testing shows it does not meet.
- Key Flaw: Suffers from residual torque, leading to post-effort reading drift.
