Quick Compatibility Guide (Chart)
| Spec | What to Check | Compatible Options | Notes |
|---|---|---|---|
| Battery Voltage & Charger Output | 36 V packs charge to ~42 V; 48 V packs to ~54.6 V; therefore, confirm output voltage and max current (A) on the charger label. | 42 V 2–3 A chargers for 36 V; 54.6 V 2–3 A for 48 V. | Match voltage exactly; furthermore, keep current within manual limits. |
| Connector Type | Measure or compare plug: DC 5.5×2.1 mm, 5.5×2.5 mm, GX16-3, XLR-3. | Multi-tip kits or exact-fit OEM. | Never force a connector; in addition, verify polarity. |
| Tire Size & Width | Sidewall stamping (e.g., 8.5×2, 10×2.125). | Same size and width; tubed or tubeless to match rim. | Choose tread for terrain and weather; meanwhile, check fender clearance. |
| Tubed vs. Tubeless | Check rim and valve type. | Inner tubes for tubed rims; tubeless tires + sealant for tubeless rims. | Do not mix types unless the rim supports it; otherwise, leaks follow. |
| Brake Type | Mechanical disc, hydraulic disc, or e-brake only. | Pads must match caliper; rotors must match mounting. | Bed-in new pads/rotors for best bite; consequently, noise drops. |
| Rotor Size | Measure rotor diameter (e.g., 140/160 mm). | Replacement must match diameter and 6-bolt pattern. | Larger rotors require caliper/frame clearance; otherwise, rub occurs. |
| Handlebar Diameter | Most scooters use 22.2 mm. | Phone mounts, mirrors, and lights with 22.2 mm clamps or shims. | Some bars vary; therefore, measure first. |
| IP Rating | Manual label (e.g., IPX4, IP54, IP55, IPX6). | Lights and mounts with equal or higher rating. | IP resists ingress, not immersion; as a result, avoid submersion. |
| Deck & Folded Size | Tape-measure both. | Straps rated above scooter weight; bags sized to folded dims. | Extra capacity increases durability; similarly, comfort improves. |
| Weight | Actual scooter weight. | Pick accessories rated above that weight. | A margin of safety helps over time; in short, overbuild slightly. |
