TST R9 Dual Suspension Fat Tire Electric Bike

Overview

The TST R9 is a fat-tire electric bike with a 750W motor (1500W peak), a removable 48V 15Ah battery, front and rear suspension and mechanical disc brakes, built for commuting and off-road riding on 20 by 4 inch tires.

The listed 1500W figure is the motor's peak output, not its continuous rating, which the description itself lists as 750W. Range is claimed at up to 60 miles in pedal-assist mode or 40 miles on throttle alone, and the bike ships 90 percent pre-assembled with a video guide for the rest.

Who it's for

It suits riders wanting an affordable fat-tire ebike for commuting or trail riding who are comfortable finishing the last 10 percent of assembly themselves.

Pros and cons

Performance notes

The 750W motor with 1500W peak output and three power modes is what gives the pedal-assist range its claimed 40 to 60 mile spread, since throttle-only riding draws more continuous current than pedal-assist and shortens range accordingly. The 7-speed gearing lets riders match cadence to terrain, which several owners said made climbs and flat cruising both feel manageable rather than one-speed compromises.
