Rider Profile
| Best For | This machine rewards skilled trial riders and punishes beginners, as its balance-point handling and lack of a seat demand real technical competence. |
| Purpose | It exists purely for technical trials competition and obstacle-based off-road riding, not for any form of transportation. |
| Rider Fit | Riding it is a full-body, standing-only workout that demands core strength, balance, and stamina rather than seated endurance. |
| Character | It has the character of a precision instrument built for momentum-free, feather-light maneuvering over rocks, logs, and near-vertical terrain. |
| Not Ideal For | It is not suitable for anyone wanting a comfortable seat, road-going capability, or a bike for touring and passenger use. |
