Euphree Solar Sparrow Belt
Class 3
Legal class
28 mph
Top speed

Battery
40 mi
Claimed range
53 lb
Weight
300 lb
Max load
53 lb is the lightest bike here that still carries a rack, fenders, lights and a 504Wh pack, and a Gates carbon belt means no chain to oil or replace. The trade is up front: single speed, so there is no gear to change for a hill, and 40 miles is the shortest claimed range on the site. An SR Suntour NCX suspension seatpost is fitted but Euphree does not publish its travel. Warranty is 5 years on frame, motor and components with the battery covered for 2.

Safety certification: UL 2849: most models, confirm this one. Euphree states: “"SGS certified to meet UL 2271 (battery) & UL 2849 (system)"” (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.
