  • 1000 W HIGH-TORQUE MOTOR (70 Nm)

  • ONE-HAND REMOVABLE 48 V 15 Ah BATTERY

    The 720 Wh lithium pack slides out with a single hand, so you can charge at your desk or in your living room. An intelligent BMS safeguards the cells; after 800+ cycles it still retains high capacity, providing a real-world range of roughly 60–80 km.

  • SHIMANO 7-SPEED DRIVETRAIN

    The proven Shimano 7-speed system delivers crisp, reliable shifts. A broad gear range teams up with the motor’s assistance to keep you spinning efficiently on flats and tackling climbs without breaking a sweat.

01

Best-Friends Cruise

Afternoon light streams down the tree-lined main drag, the red-and-mint frames popping against café awnings. With 70 Nm on tap and 27.5″ wheels plus full fenders, the duo can drift from downtown pavement to suburban lanes without a second thought—just ride together and enjoy the day.

02

Beach Amusement Park

Golden hour paints the Ferris wheel while a red and a sea-foam step-through e-bike roll easily along the shore path. Wide 27.5″ × 2.25″ tyres track confidently on packed sand, and the fork-and-disc combo keeps the ride as smooth as the ocean breeze.

03

Urban Commute

Seconds before the light switches, the rider pauses with a smile. The 1 000 W motor and 70 Nm of torque promise an instant launch, the one-hand 48 V 15 Ah pack covers up to 65 miles of daily errands, and twin hydraulic discs stand ready for split-second stops.

04

Seaside Duo

Beside the pier, two bikes rest wheel-to-wheel, amusement-park neon dancing on their frames. A 400 lbs payload takes boards or beach bags in stride, and at just 58.86 lbs each bike is easy to walk or pedal across the sand.

05

Park Trail Ride

On a grassy park trail the knobby tread leaves crisp tracks. A 100 mm fork irons out chatter, the Shimano 7-speed lets friends sync their cadence from climbs to flats, and hydraulic discs rein in speed on every descent.

Improvements: You should - Go ahead and attach the derailer guard in house as leaving it for the consumer with an instruction that reads “don’t attempt to install this single nut piece as it should be done by a professional- this requires a 99.5 % assembly at home, but then requires some kind of transportation to get the bike to the Bike Shop to submit it for the day or maybe longer for the professional to loosen the one nut and install the derailer and tighten it back up because there’s danger of ruining the alignment with the motor, etc. this is all factory operation so change that and that would be great thanks

Proper ebike

You can use pedal assist or just the throttle. Rode 26 miles around Fort Myers, Florida and still had over half my battery life. I was using only the throttle for a good portion of the ride.

I just recieved them and assembled the TST however the screws to the kickstand are to small for the holes in the frame, they are to short and not thick enough to **** into the frame. Please respond as to how to rectify. thank u

Pleased with function of electric bike

Took our new bike on its first ride. Its assembly was easy, having experience working on my own bikes before. My wife is not as strong as she was, she was able to ride the bike easily. Only complaint is the slowest it will go is 10 mph. It made it hard for me to keep up on my traditional bike.
