Who it fits

Key specs explained for this e-bike

Motor Power: 750W (2000W peak)

This motor provides 750 watts of continuous power, with a peak output of 2000 watts for short bursts. You will notice strong acceleration when starting from a stop or climbing steep hills. The higher peak power helps the bike handle varied terrain, from smooth city streets to light off-road trails. This setup ensures you maintain speed without straining the battery during sudden demands.

Battery Capacity: 25Ah

The 25Ah battery stores a significant amount of energy, supporting a maximum range of up to 100 miles in pedal-assist mode. This capacity allows for longer commutes or weekend rides without frequent recharging. You can remove the battery for convenient indoor charging. A higher amp-hour rating generally translates to greater distance per charge, making this suitable for extended daily use.

Battery Voltage: 48V

A 48-volt system delivers consistent power to the motor, ensuring efficient performance across various speeds. This voltage level is standard for many adult electric bikes, balancing power delivery with energy efficiency. You will experience smoother acceleration compared to lower voltage systems. It also supports the high-capacity battery, helping maintain speed on inclines and reducing drain during long rides.

Suspension: Full suspension

Full suspension means the bike has shock absorbers on both the front wheel and the rear frame. You will feel less impact from potholes, curbs, and rough road surfaces. This design improves comfort and control, especially on uneven terrain or dirt paths. It reduces fatigue on longer rides by isolating your body from vibrations. This feature is valuable if you frequently ride on mixed surfaces.

Bike Type: Step-thru

The step-thru frame design features a lowered top tube, allowing you to mount and dismount the bike easily. You do not need to swing your leg high over the frame, which is helpful if you wear skirts or have limited mobility. This style offers a more accessible riding position for many adults. It simplifies getting on and off at traffic lights or when parking, enhancing everyday convenience.

Design and build details

The TST Step-Thru Dual-Seat Electric Bike features a step-thru frame layout designed for easy mounting and dismounting. This design is particularly useful for adult riders who prefer convenience or have limited mobility. The listing describes the build as suitable for both urban commuting and light dirt bike trails. You get a full suspension system to absorb bumps and keep the ride smooth. Full-coverage fenders are included to block mud and water, which protects your clothing and the bike’s components during wet conditions.

According to the listing, the bike weighs 87.67 lbs and supports a maximum load of 450 lbs. This capacity allows you to carry a passenger comfortably. The frame includes two seats and rear footrests for the second rider. The rear seat area also supports DIY modifications, such as adding a trunk for extra storage. The battery is built into the frame in a removable design. This integration aims to provide a sleek look while keeping the power source secure and waterproof.

The finish comes in multiple color options, including Ink, Orange, and Matte Black. The listing notes that the battery housing is anti-theft and anti-collision. Mechanical disc brakes provide the stopping power. High-brightness front lights and reflective taillights improve visibility at night. The assembly is mostly pre-done, requiring only minor setup. This build focuses on practical utility and shared riding rather than high-speed performance.

Setup and daily use details

Assembly is straightforward because the e-bike arrives ninety percent pre-assembled. You only need to complete the remaining steps using the included video and manual. The listing notes that you should check if parts are tightened before riding. This initial setup ensures the mechanical components are secure for your first ride. The bike weighs eighty-seven point six seven pounds, which is manageable for moving it into your home or garage. The removable battery design simplifies charging. You can take the forty-eight volt, twenty-five amp-hour pack off the frame and charge it indoors. It takes six to seven hours for a full charge. This means you do not need to move the entire eighty-seven-pound bike to a power outlet. Daily use benefits from the step-thru frame, which allows you to mount and dismount easily. The full suspension system absorbs bumps from city streets or light trails. Full-coverage fenders keep mud and water off your clothes and the bike’s components. Safety features include high-brightness front and rear lights for visibility in low light. Mechanical disc brakes provide reliable stopping power. The dual-seat configuration lets you carry a passenger using the rear footrests. You can also modify the rear seat area to add a trunk for storage. With a maximum load capacity of four hundred fifty pounds, the frame supports heavier riders and cargo. The waterproof and anti-theft battery housing adds peace of mind when you leave the bike outside. This setup supports both short commutes and longer rides up to one hundred miles in pedal assist mode.

Before You Buy This E-Bike

You should verify that your local laws allow a 750W motor and 2000W peak output for your intended routes. Some municipalities restrict motor power or top speeds for street use. Check your bike rack compatibility, as the 87.67 lb weight and dual-seat frame may not fit standard car racks. The 48V 25Ah battery is removable, so ensure your charging space has a grounded outlet. Full suspension requires periodic maintenance of the fork and rear shock. Inspect the mechanical disc brakes for pad wear, as they require manual adjustment. The dual-seat design invites passengers, but confirm that local regulations permit carrying a second rider on an e-bike. This model suits riders needing high load capacity, but you must weigh it against lighter, single-rider options if portability is a priority. Regularly check bolt tightness, especially after the initial ride.

Check before you buy

• Confirm local motor power and speed regulations apply.
• Verify car rack compatibility with the heavy frame.
• Ensure accessible grounded outlet for battery charging.
• Check if local laws allow dual-rider usage.
