The TST X6 is a dual-seat electric bike built around a 750W motor (1500W peak) and a UL 2849 certified 48V 15Ah removable battery, aimed at riders who want to carry a passenger or gear on a fat tire commuter.
The dual-seat layout is the standout feature here, letting a second rider sit behind the operator rather than relying on a single saddle, though that also pushes total bike weight to about 87.74 lbs. TST separates its range claims by mode: up to 40 miles on throttle alone and 50-60 miles in pedal-assist, a more useful distinction than a single blended figure.
- 750W motor, 1500W peak output
- 48V 15Ah UL 2849 certified removable battery
- Dual seats and 450 lb max load
- 20 x 4 inch puncture-proof tires with front and rear suspension
Who it's for
Fits riders who want to bring a passenger along or need a heavier-duty commuter with a 450 lb load rating. Less suited to anyone who needs to carry the bike up stairs regularly, given its weight.
Pros and cons
- Dual seats for carrying a passenger
- UL 2849 certified removable battery
- 450 lb max load rating
- Front and rear suspension plus puncture-proof tires
- At about 87.74 lbs it is heavy to lift or carry
Performance notes
The 750W motor (1500W peak) works with front and rear suspension and 20x4 puncture-proof tires to handle mixed terrain, while front and rear lights, including a reflective, turn-signaling taillight, are built in for visibility. The 48V 15Ah battery is UL 2849 certified and charges in 6 to 7 hours, with TST listing separate range figures for throttle-only and pedal-assist riding.
