Key specs explained
Motor Power: 750W (2000W peak)
This motor provides 750 watts of continuous power, with a peak output of 2000 watts for short bursts. The higher peak helps you accelerate quickly and climb steep hills without slowing down. You get strong torque for handling heavy loads or rough terrain. This power level suits riders who need assistance on inclines or want faster starts in traffic.
Battery Voltage: 48V, Capacity: 15Ah
A 48-volt, 15-amp-hour battery stores energy to run the motor. This capacity typically supports ranges up to 65 miles in pedal-assist mode. A higher amp-hour rating means more stored energy, allowing for longer trips between charges. You can remove the battery to charge it indoors, which adds convenience and safety for apartment dwellers.
Wheel Size: 20 inches, Size: 20"x4"
These 20-inch wheels feature 4-inch wide fat tires. The wide profile increases surface contact with the ground, improving grip on loose surfaces like sand, snow, or gravel. The larger diameter helps roll over bumps and potholes more smoothly. This setup is ideal for riders who frequently travel on uneven or unpaved paths.
Suspension: Front and rear
This bike includes shock absorbers at both the front fork and the rear frame. Front suspension handles bumps from the road, while rear suspension reduces impact on your spine. Together, they smooth out rough terrain and reduce rider fatigue. You benefit from a more comfortable ride, especially on cobblestones, dirt trails, or cracked pavement.
Maximum Range: Up to 65 miles
The manufacturer states the bike can travel up to 65 miles on a single charge. This distance is usually achieved using pedal-assist mode, where your pedaling effort helps the motor. Throttle-only mode typically reduces this range. This capacity supports daily commutes and weekend rides without frequent recharging, provided you use assist levels wisely.
Design and Build Overview
According to the listing, the TS TST GRP R7 features a gloss black finish available in six black variations. This includes options like matte and obsidian black. The frame supports 20-inch by 4-inch fat tires. These wide tires provide a large contact patch. This design choice helps you maintain traction on loose surfaces like sand, snow, or gravel. It also absorbs small road imperfections for a smoother ride.
The layout includes dual seats. This upgrade allows you to carry a passenger comfortably. It makes the bike suitable for shared rides or commuting with a friend. The front and rear suspension system is integrated into the frame. This setup reduces fatigue by absorbing bumps from uneven terrain. You can use the bike on rough paths without excessive vibration affecting your comfort.
Controls and safety features are built into the design. A high-brightness front headlight ensures visibility during night rides. A reflective taillight signals your presence to traffic. The braking system is described as responsive. This provides reliable stopping power in various conditions. The removable battery is mounted on the frame. This allows you to take it off for charging indoors. The overall build prioritizes stability and utility for adult riders navigating mixed environments.
Setup and Daily Use Guide
This e-bike arrives with a 48V 15Ah removable battery. The listing notes it requires 6 to 7 hours for a full charge. You can take the battery out to charge it indoors or on the go. This design keeps the bike lighter when you are not using electric assist. The motor delivers 750W of continuous power, with a peak of 2000W. This power helps you reach higher speeds and climb steep slopes up to 35 degrees. You get 90 Nm of torque for strong acceleration and hill climbing. The 20-inch by 4-inch fat tires offer stability on various surfaces. They provide grip on rugged terrain and snowy paths. The front and rear suspension system absorbs bumps. This reduces fatigue on longer rides. You can share the journey with the dual seats. This feature is ideal for commuting with a partner or friend. Safety features include a high-brightness front headlight and a reflective taillight. These lights ensure visibility during night rides. The responsive braking system provides quick stopping power. You can choose from six black color options, including gloss, matte, and obsidian. The bike is designed for adults. It supports both pedal-assist and throttle modes. In pedal-assist mode, you can travel up to 65 miles. In throttle-only mode, the range is about 40 miles. This setup makes it suitable for daily commutes or weekend adventures.
Before you buy this e-bike
You should verify local regulations for 750W motors and 20-inch wheels. These bikes often fall into specific legal classes. Check your city rules on throttle use and speed limits. The removable 48V battery requires a standard household outlet. Ensure you have a secure charging spot indoors. The dual seat adds weight and changes the center of gravity. You need a sturdy rack if you plan to transport it. The fat tires offer comfort but increase rolling resistance. This affects your range in throttle mode. Compare this model to lighter options if you prioritize speed over cargo capacity. Regular maintenance includes checking brake pads and tire pressure. The front and rear suspension needs occasional inspection. Keep the chain clean and lubricated. This bike suits riders who value stability and shared rides. It is less ideal for those seeking lightweight portability. Always wear a helmet and follow traffic laws.
Check before you buy
- Check local laws for 750W motor class restrictions
- Verify charging outlet availability for the removable battery
- Confirm weight capacity for the dual seat setup
