The mid-drive Level 4: Aventon's Ultro S with 100 Nm, against the hub-motor REC at 80 Nm. Bigger 800Wh Samsung pack too, and 61 lb versus the REC's 68.5. Suspension fork and seatpost. Battery UL 2271 certified. Aventon lists the pack as "36V, 20Ah, 800Wh", which cannot all be true — 800Wh at 20Ah implies a 40V nominal pack. Their 800Wh figure is recorded and the voltage left blank.

Safety certification: UL 2849: full system. Aventon states: “UL and TUV Safety Certified - UL 2849 / UL 2271” (source). That is the manufacturer’s own claim, not something we verified, you can check a specific model in UL’s Product iQ database. Why this matters.
