The Tern GSD S10 Gen 3 is a cargo e-bike — representative silhouette: Cargo longtail. We have read 5 specification sheets (Tern and Magura) and recorded 10 fit facts from them. 6 of the 16 measurements a cargo e-bike needs to answer fit questions are on file; 2 are confirmed by two independent sources. Where a measurement is missing, we say so below — we do not guess.
| Rear axle spacing | Thru-axle, 148 × 12 mm (Boost) |
|---|---|
| Front axle spacing | Thru-axle, 110 × 15 mm (Boost) |
| Brake actuation | Hydraulic disc |
| Brake pad shape (fitted calipers) | Magura MT C ABS, 4-piston — Performance pads only |
| Rear speeds | 10 speeds |
| Shift actuation | Mechanical (cable) |
| Chain standard | 10-speed (6.0 mm) |
| Brake actuation, rear | Hydraulic disc |
| Brake pad shape, rear caliper | Magura MT C ABS, 4-piston — Performance pads only |
| Electric assist system | Pedal assist |
Confidence: 4 facts are verified by two independent sources; the rest come from a single cited source ("derived").
Not on file (required for a cargo e-bike): Bottom bracket shell · Derailleur hanger · Seatpost diameter · Maximum tyre width (frame) · Wheel size (ISO bead seat) · Brake mount, front · Brake mount, rear · Rotor interface (hubs) · Freehub body · Pedal thread. The sheets we read do not state them; until a source does, confirm these measurements before choosing a part that depends on them.
- Why do so many verdicts on this bike read "unknown"?
- Because a verdict needs the bike's measurement for every dimension a part requires, and 10 of the 16 required measurements are not on file. "Unknown" means we could not check — not that it fits, and not that it does not.
- Will the verdicts change?
- Yes. When a second independent source confirms a measurement — or a first one states a missing one — the verdicts are recomputed from the new facts. Nothing on this page is typed by hand.
