ThinkRider XXPRO Direct Drive Smart Bike Trainer Max 2500W Indoor Training Generate Electricity By Oneself Bicycle Roller

With extended use (hundreds of kilometers), the trainer performs reliably. Climb and descent simulation is realistic and smooth, pedaling feels natural. Noise levels are low during normal power output (up to 230–250 W); during sprints and steep climbs, sound increases but remains acceptable. A major advantage is operation without mains power — it generates energy through pedaling. Some users noted that in ERG mode, power response can lag up to five seconds during sudden load changes.

Main complaints concern compatibility: virtual shifting in Zwift and Rouvy does not work, which may be problematic for some. A few buyers reported weak grip during steep climbs at high power. Cassette and freehub are not included — you must purchase them separately and verify compatibility with your drivetrain (especially SRAM). The ThinkRider app occasionally has connection issues, though the trainer itself connects reliably. The power connector is exposed to sweat moisture, which some consider poor placement.
