The E350 Electric Trike puts pedal-assist power and three-wheel stability together — so every ride feels effortless and every destination feels closer.
"Stable, smooth, and electric — built for riders who want more from every mile."
The Sun Bicycles E350 Electric Trike combines the timeless stability of a three-wheel design with the ease of modern electric pedal-assist technology. Whether cruising beach paths, running errands, or exploring your neighborhood, the E350 delivers a confident, comfortable ride backed by a reliable 350W motor and a removable lithium-ion battery. It's more than a trike — it's independence in motion.
Every component of the E350 is engineered for reliability and ease of use — from the powerful drive system to the practical storage solution.
A quiet, efficient 350W brushless front hub motor delivers smooth pedal-assist power — making hills feel flat and long rides feel effortless.
The integrated 48V lithium-ion battery slides out easily for convenient indoor charging — no need to bring the whole trike inside.
A clear backlit TFT display shows speed, battery level, trip distance, and current assist mode — all at a glance while you ride.
The handlebar-mounted throttle lets riders engage electric power on demand — perfect for starting from a stop or tackling sudden inclines.
A generously-sized rear cargo basket sits over the rear axle — ideal for groceries, gear, or everyday essentials. Practical meets practical.
A generously wide, plush-padded saddle provides all-day comfort — designed to support riders on longer journeys without compromising on cushioning.
The E350 isn't just a trike with a motor — it's a rethinking of what cycling independence can feel like.
Whether you're running errands, exploring coastal paths, or simply enjoying the ride — the E350 fits the way you live, not the other way around.
Everything your customers and your floor staff need to know about the E350 Electric Trike — all in one place.
