Kingbull Trekker Step-Through Electric City Bike
The Kingbull Trekker is a 26-inch step-through fat tire city eBike designed for long-distance commuting and recreational riding, with a Samsung 960Wh battery and Tektro 4-piston brakes.
The Trekker is powered by a Bafang G062 750W brushless rear hub motor with 1,400W peak output and 90 N·m of torque, paired with a TROG-1B torque sensor for smooth, proportional pedal assist across 5 levels plus a twist throttle. Class 2 at 20 mph ships as default; Class 3 at 28 mph is unlockable via the display menu, with the throttle-only top speed capped at 20 mph.
. The 48V 20Ah (960Wh) Samsung INR21700-50G battery carries UL 2580 certification and a claimed range of up to 80 miles per charge. Owner reports confirm extended range at low assist, with one rider logging 250 miles on the bike within a month and a half of ownership. The 48V 25A controller and UL-certified 3.0A smart charger are included.
The Trekker runs 26 x 4.0-inch Kenda K-1188 puncture-proof fat tires on JP73 aluminum alloy 36-hole wheels, providing a planted, stable ride at higher speeds on varied surfaces. The 700mm handlebar and fixed aluminum alloy stem result in an upright, confident riding position.
The frame is a step-through aluminum alloy design with a tapered head tube, integrated battery, and guided internal wiring. Suspension is handled by a ZOOM 879 coil spring fork with 80mm of travel, adjustable damping, and lockout. Stopping is handled by Tektro HD-E3940 4-piston hydraulic disc brakes with 180mm rotors and power-off brake levers front and rear.
The Shimano SL-M315 8-speed trigger shifter, RD-M310 rear derailleur, and DNP 13-32T cassette round out the drivetrain. A 4.0-inch full-color multifunction display, 48V LED headlight with horn, brake-activated taillight, all-aluminum rear rack rated for 150 pounds, plastic fenders, and an adjustable kickstand are all included standard. The Trekker is IPX6 rated and UL 2849 certified, weighs 79 pounds, and supports a maximum payload of 450 pounds. Seat height is adjustable from 33.5 to 36.6 inches, suitable for riders from 5’3″ to 6’6″. A $200 Power Station Bundle option is also available.
