Overview

The TST R7 pairs a 750W motor rated to 1500W peak with a 48V 15Ah removable battery in a 20 inch fat tire frame. It is built as a step-thru commuter with dual seating, aimed at riders who want one bike that can also carry a passenger.

Rated range spans 40 to 60 miles depending on throttle versus pedal-assist use, and the battery detaches for indoor charging in 6 to 7 hours. A shock-absorbing full suspension and full-coverage fenders point this toward mixed pavement and light off-road riding rather than pure road commuting.

  • 750W motor, 1500W peak power
  • 48V 15Ah removable battery, 6-7 hour charge
  • Up to 60 miles range in PAS mode
  • 450 lb max load capacity

Who it's for

Riders who want a fat tire step-thru ebike that can carry a second rider on the included dual seats and rear footrests. Also suits shoppers who plan to add a trunk box to the DIY-ready rear seat mount.

Performance notes

The 750W motor produces enough pull for daily commuting and light off-road use, with 1500W peak power available for hills and acceleration. Mechanical disc brakes and full suspension handle stopping and bump absorption, and the anti-theft, waterproof battery housing is built into the frame rather than bolted on.
