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.
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.
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.
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.
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.

Customer Stories
Battery capacity & Price
- My Great Challenge
This is an incredibly cute-looking electric bike. The TST Flyer boasts some sharp colors. I love the concealed battery, which has a capacity of 48 volts and 15 amp-hours. A 1000-watt power is sufficient for most people. If you encounter steep terrain, you can assist by pedaling. Not sure if there's an e-bike with that budget-friendly price tag, but for what you're getting, it's great. It offers high value for money, coming in at just $989. You could have your first electric bike in life with that!

TST® Surfer 27.5" Step-Thru Commuter eBike
my husband bought this bicycle for me for Christmas. It came broken would not work. You sent me a motor and a controller and that does not work either. I still have a broken bicycle. It is terrible that he would send out two customers a broken bicycle I want a return label I want it sent back. I want my money back. You sent me a completely broken bicycle.
I got the bike,while I was nerves to put it together I manage to do it and it is a smood ride ,battery was fully loaded and looks beautiful.I bike and comute all the time but have few injuries where ebike comes handy.I got a new years deal at $830 so couldn't ask for more ,the battery have a key and bike is sleek not very heavy.
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
