What Our Gearhead® Experts Are Saying: "I’ve tested these on a 26-inch cruiser for an adaptive cycling setup, and they hold up great. The heavy-duty steel construction is surprisingly stable, even under full adult weight. Adjustability makes them a fit for multiple bikes, and the rubber-tired 6-inch wheels roll smooth. Great for riders who need a permanent or transitional support solution."Whether we’re helping someone learn to ride or offering extra support for adaptive cycling, the Sunlite HD Adjustable Training Wheels deliver the strength, fit, and confidence we’re looking for. Sunlite built these with a full steel frame and rubber-tired 6-inch wheels for a grounded, road-ready feel that doesn’t give out after a few rides.
