The three methods
| Method | Parameter | What it does |
|---|---|---|
| Speed limit | P08 | Caps top speed. 0 = no limit; the value is in km/h |
| Drive mode | P10 | 0 = power, 1 = electric, 2 = coexist |
| Start intensity | P12 | 0–5 — how hard the motor comes in from a stop |
Steps
- Decide which you actually want. If the concern is top speed, use P08. If the concern is how abruptly the bike launches, that is P12, not P08.
- Open the parameter menu and navigate to the chosen parameter.
- Set the value. For P08, the number is in km/h — 25 km/h ≈ 16 mph.
- Save, exit, and power cycle.
- Test at low speed in a safe open area, then confirm the cap holds.
A speed cap is not the same as gentler acceleration
A common misconception. Lowering P08 limits how fast the bike will eventually go. It does not change how hard it accelerates up to that speed — the bike still comes off the line just as sharply. For a new or younger rider, P12 is usually the more useful setting.
Watch out for
- Setting P08 to
0expecting "slow".0means no limit, not "stop". - Assuming a speed cap makes the bike suitable for a smaller rider. Fit, reach and weight matter more than top speed — see Rider Fit & Sizing.
- Changing P03 or P14 while you are in the menu. Neither has anything to do with speed, and both cause real faults.
