Review on 🚲 Wald W10252 Bike Training Wheels (16-20 Inch Wheels, .75-1 Inch Frame Tubes) by Joe Ashan

They are very strong and above all: they do not fall. An additional cross brace that attaches to the bike frame holds the wheels at a 90-degree angle. The frogs come with nice thick rubber pads that should protect the bike's paintwork while we use them. Finger" to put them on the bike, otherwise they would get blocked by the components. I hope you can see it in the photo I took. Like most training wheels, they do NOT have bearings. Just direct metal- I replaced the wheels with cheap 140mm scooter wheels with bearings and mounted them using M8 60mm bolts, regular M8 nuts, M8 nylock nuts and 1/4 washers as bearing spacers. Not a mandatory upgrade, but much quieter.
