Germany's oldest city, founded by the Romans around 16 BC: the Porta Nigra, an amphitheatre, imperial baths, and a UNESCO-listed old town — followed by the Mosel-Radweg cycling path through terraced vineyards. Needs 1–2 Supercharger stops each way.
Trier calls itself Germany's oldest city, and the Roman remains back it up: the Porta Nigra is the best-preserved Roman city gate north of the Alps, still black with age, and the old town also holds a Roman amphitheatre, the ruins of the vast Kaiserthermen (Imperial Baths), and Germany's oldest cathedral, all UNESCO World Heritage-listed. It's a genuinely different flavor of trip from the usual French weekend — a full day of ancient-history sightseeing, then a slide straight into the Moselle wine valley, one of the most scenic river-and-vineyard cycling regions in Europe, with a flat, well-marked long-distance path (the Mosel-Radweg) running right through town.
Distance/route: Paris–Trier via A4/A1/E44 is roughly 410 km direct-route-comparable, ~370 km as the crow flies, 4–4.5 hrs pure driving — Meudon-la-Forêt adds a little, landing around 441 km. (distancecalculator.net, wayro.ai route guide)
With realistic range of ~330–370 km on this Model Y Premium (97% SOH), the ~441 km run needs at least one stop, more comfortably two with margin for detours and weather.

Early start. First charge near Metz (Hauconcourt or Moulins-lès-Metz), second top-up at Luxembourg Urban if needed — or push straight through to Trier's own Supercharger and charge there instead, depending on state of charge and how much you want to linger. Arrive Trier by mid-afternoon; settle into camp, then an easy first look at the Porta Nigra lit up at dusk — it's genuinely striking after dark.

Full day of Roman Trier. Individual entry to the Porta Nigra, Kaiserthermen, or the Amphitheatre runs about €6 each — but the Antikencard combo ticket is the better deal: €18 for the Rheinisches Landesmuseum plus two of the four Roman sites, or €28 for the museum plus all four (Porta Nigra, Kaiserthermen, Amphitheater, Thermen am Viehmarkt). The card stays valid for the rest of the calendar year, useful if you split sightseeing across two days. Trier Cathedral (Trierer Dom), the oldest cathedral in Germany, is free to enter. Round it out with a walk through the old town — Hauptmarkt square, the Basilica of Constantine (also free), and the general feel of a 2,000-year-old Roman colonial capital.

The Mosel-Radweg is one of Germany's most celebrated long-distance cycling routes, running the full length of the Moselle from France to the Rhine, and it passes right through Trier — flat, well-signed, hugging the river through terraced vineyard slopes on both banks. Ride out toward villages like Trier-Olewig or further into the valley (Konz, Kanzem) as far as your legs want; the path makes it trivial to turn any distance into a loop back to camp. Stop at a Winzer (winegrower) along the way for a tasting — Mosel wine tastings typically run €10–30 for a standard flight, sometimes waived with a bottle purchase, with more elaborate vineyard-tour tastings going up to €50-90. A simple roadside or cellar-door tasting at €10–20 fits the trip budget easily.

Top up at the in-town E-Center Supercharger before leaving if convenient, then reverse the route: Luxembourg Urban, then Hauconcourt or Moulins-lès-Metz, then home. Budget the same 5–5.5 hours driving plus stops.
Bike loaded inside per the Car Camping & Bike Guide — no range penalty, no rack needed. The Mosel-Radweg is the standout reason to bring it on this trip: a genuinely famous, flat, riverside long-distance path running directly through Trier and the surrounding vineyard villages, so no driving is required to reach great riding — just roll out from wherever you're camped.
