More from this brandAll TS TST GRP LLC electric bicyclesOverview
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.

The 750W motor produces enough pull for daily commuting and light off-road use, with 1500W peak power available for hills and acceleration.
