Removable battery, but heavy
The Robo-S uses a removable lithium pack (typically ~60V/40Ah, around 2.3–2.4 kWh) so you can charge it indoors without a garage socket — but it weighs roughly 20 kg, which is awkward on stairs. Check the carry handle, latch and connector pins for wear, as these take the most abuse.
Bosch motor, budget trim
It pairs a reliable Bosch-branded rear hub motor with lower-cost cycle parts, so the drivetrain usually holds up while brakes, bearings, plastics and rear shocks show wear first. Also verify the dealer/parts support in your area — Sunra's network is thinner than Piaggio or Vespa.
Battery health drives resale
Like most L1e electric mopeds, it depreciates faster than a petrol 50cc, and value hinges almost entirely on battery condition and remaining warranty. Insist on a test ride from a full charge to confirm real-world range (expect well under the claimed 80+ km at full 45 km/h speed) and ask for the battery's cycle history.
