Meet the Bluvall SU8 — Small Moto Energy, Everyday Utility

The Bluvall SU8 blends the stance of a mini-moto with the practicality of a commuter e-bike. A 52V, 1500W rear hub motor delivers confident acceleration and hill-taming torque, while the dual-crown front fork (120 mm travel) and heavy-duty rear shock (210 mm × 800 lb) flatten potholes and gravel paths alike. Add hydraulic brakes, bright integrated lighting with turn signals, and a long bench saddle, and you’ve got a fun, comfortable, and capable ride for commuting, campus, delivery, or weekend exploring.

A big 52V 20Ah (1040Wh) removable battery—UL 2849 & UL 2271 certified—powers up to 60 miles of pedal-assist range. Full fenders, an easy-read LCD with USB phone charging, and IPX6 weather protection make daily use simple. With a 353-lb payload rating, the SU8 is built for bigger riders or extra cargo without losing composure.
