Overview
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.

Performance notes

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.
