How we checked

The Cyclingnews review (dated 27 June 2022) covers the exact "Rubbee X" base model and provides a full spec table confirming 250W power, 25 kmh/16 mph top speed, 2.8 kg/6.1 lbs base weight, and a EUR 579 base-unit price; its body text confirms a wireless cadence sensor, ~10 minute installation, and smartphone-app assist control. InsideEVs (15 June 2022) independently corroborates the same Rubbee X: 16-to-29-inch wheel compatibility, 16 mph base top speed, one included modular battery pack, and an approximate "$620 USD equivalent" rather than an official US MSRP. Because Rubbee prices only in EUR/GBP with no published US MSRP, the price is left blank; voltage, torque, battery Wh capacity, and discrete PAS-level count were not stated on either fetched page and are removed. The manufacturer site (rubbee.co.uk) refused all connections and a third SEO page carried self-contradictory figures, so it was discarded.
