Technical Bike Assessment (manual coach form)

What this assessment is

The Technical Bike Assessment completes the technique trio with the Technical Swim Assessment and the Technical Run Assessment: a manual coach observation form for bike-handling skill — control, cornering, fueling on the move, and mechanical self-sufficiency.

The sections

1. General: bike used, years riding, group-riding experience, crash history / lingering fears, and the test conditions (surface, wet or dry, pedals).
2. Bike at a Glance (1–5): quick ratings across the major handling elements.
3. Slow-speed control (1–5): the drill battery — track stand, staying in a box, holding a line while looking at an object, slalom, figure eight.
4. Dynamic skills (1–5): left and right U-turns, braking technique, descending, one-hand and no-hand riding, bunny hop, riding over obstacles.
5. Hands-off & fueling handling (1–5): grabbing, using and returning a bottle — inner frame, behind the saddle, cockpit — plus taking a bottle from a table or the ground at speed.
6. Speed skills: the Infinity Test (below) and related timed work.
7. Triathlon-specific (1–5): mounting, dismounting, riding in traffic near other athletes.
8. Mechanical self-sufficiency: maintenance and roadside-fix ratings.
9. Summary: overall scores and free-text prescription.

Ratings are on the same 1–5 scale as the swim and run cards, so the three dashboards read consistently.

The Infinity Test

A measurable cornering benchmark:

• Two cones 100 m apart, each inside a 2.5 m turn box.
• Ride a figure eight: right-hand turn around one cone, left-hand turn around the other. Ten full laps, timed.
• Suggested warm-up: ~20 min easy at 60–65% of FTP with 3 × 3 × 15 s activations at 130–150%.

Grepiac converts the time to a 1–5 score against a world-class benchmark for the athlete's sex (M ≈ 4:30, F ≈ 5:00): within 10% of the benchmark scores 5, within 25% scores 4, within 45% scores 3, within 70% scores 2, slower scores 1. The bands are a first cut and will be tuned as squad times accumulate.

Where the results show up

The bike page of the athlete's sport analytics gains an assessment card — same pattern as the swim card — with the at-a-glance bars, the skills grid, the Infinity score, and assessment history. Descending and handling scores also feed coach-observed evidence into race-selection tooling, where a coach's observation outranks self-reported confidence.

How to run the review

A full session takes 45–90 minutes on a closed surface (empty car park or quiet loop). The form is partial-save friendly: score what you observed, leave the rest blank, and retest specific sections later.
