The E-Delta B1 SX Electric Assist Delta is engineered around a proven Bafang B1 electric propulsion system featuring a 350-watt pedal-assist rear mounted mid-drive motor paired with a 48V / 10.5Ah lithium-ion battery pack, delivering smooth assist and speeds of up to 15 mph. For complete peace of mind, every electric trike is ACT Lab tested to UL 2849, UL 2271, and CPSC standards, ensuring the highest level of safety and compliance.This is our most affordable pedal-assist delta trike—but “affordable” doesn’t mean “basic.” The E-Delta B1 SX incorporates stability and easy mounting inherent to a delta frame while offering rider-focused features such as a fully adjustable mesh-back saddle with a padded bottom, providing excellent comfort and ventilation for long outings. Additional bottle-mount locations on the seat frame and handlebars allow you to carry ample hydration for extended rides.Built for reliability, comfort, and value, the E-Delta B1 SX is the perfect entry into electric-assist recumbent delta triking.
