The OnEll range offers elliptical bikes with 3-speed or 8-speed Shimano Nexus hubs. The number identifies the model's drivetrain configuration. Compare it alongside frame type, your routine, and the brand's guidance.
Which models have each configuration
| Model | Gears | Frame |
|---|---|---|
| OnEll F3.20 | Shimano Nexus 3 | Fixed |
| OnEll RX3.20 | Shimano Nexus 3 | Fixed |
| OnEll FD3.20 | Shimano Nexus 3 | Folding |
| OnEll F8.20 | Shimano Nexus 8 | Fixed |
| OnEll FD8.20 | Shimano Nexus 8 | Folding |
All models in the table have 20-inch wheels. When comparing the F3.20 with the F8.20, you are looking at two fixed-frame options with different drivetrains. When comparing the FD3.20 with the FD8.20, both options retain the folding feature.
Separate gears from frame type
If you need a folding frame, start with the FD versions and then assess the drivetrain. If your plans allow a fixed frame, look at the F and RX ranges. Making these choices separately helps you understand what you are comparing.
The RX3.20 deserves its own review: the brand lists a 14-tooth chainring and availability exclusively in black. See what sets the RX3.20 apart before treating it as an F3.20 with a different name.
What to ask about your route
Give support a clear description of your intended use: location, route type, and how often you expect to ride. Ask which riding and gear-changing instructions apply to your chosen configuration.
The number of gears alone does not establish a maximum speed, a supported incline, or a person's effort. These outcomes should not be inferred solely from a model code. A specific assessment requires information beyond the catalog table.
Compare the whole package before buying
Open the OnEll F3.20 and OnEll F8.20 to examine the fixed-frame options. For folding models, see the FD3.20 and FD8.20.
Check prices and availability directly on the product pages, as this information can change. Before making your choice, also confirm the measurements needed to store and transport the bike. The complete comparison brings together the range's confirmed differences.
