Assault Bike and Echo Bike Pacing: Calories, RPM, and Metcon Strategy

Fan bikes punish ego: first-buy sprint calories and sustainable round splits conflict every time. Calories climb when you stay smooth; they stall when you redline then die. Assault/Air and Echo feel different, but the skill is the same — pick an RPM window and hold it. Build pieces in the WOD Generator; compare formats in the AMRAP guide.

RPM Is Your Pace

• Drive with legs first; arms finish — not the reverse
• Note cal/min at 55–65 vs 70–80 RPM on your machine
• Echo often feels heavier at the same RPM — don’t copy a friend’s Assault numbers
• Console calories ≠ watch calories — use the console for the WOD; the Calories Calculator is a rough daily aid

Numeric scenario: 2–3 min steady test averages 62 RPM and 14 cal/min. AMRAP with 12/10 cal buys: open at ~80–85% ≈ 11–12 cal/min (slightly slower RPM), last buy at 95–100%. If cal/min drops >15% mid-WOD, you opened too hot — drop ~5 RPM next round. Couplet example: 12/10 cal + 10 thrusters — if the bike forces thruster singles by round 3, the bike was too hot.

Decision rule: if the next movement loads legs (thrusters, squats, burpees), cap bike at a pace you can leave and still unbroken that movement; if the bike is the finish, you may surge the last 20–30%.

Templates

• AMRAP buysFirst buy 80–85% of tested cal/min; last buy 95–100%
• EMOM 12Odd 12/10 cal · even 8–10 squats/swings · ≥10 sec rest
• AMRAP 1010/8 cal + 8 push-ups + 12 lunges · hold cal time within 5 sec
• For Time30-20-10 cal + burpees · open cal ~10% slower than max 2-min test

Easy spin ~40–55 RPM · sustainable metcon ~55–70 · short surges 15–30 sec only

Practical Takeaway

Know your steady RPM → cal/min map, open slightly conservative, and protect what follows the bike.

FAQ

Assault vs Echo — which is harder?

Depends on machine and athlete. Pace by your console data on the bike you’ll use in the workout.
