This past weekend Weston did his first strider race at the BMX track. He is just 2 yrs old (25 months, he has been riding for 12 months now). We went Friday night to spectate the Nationals and play around and he demanded, "My bike race NOW!" so we signed him up for Saturday. He had fun.
I was shocked he was one of the only kids without a FF helmet. We now have that on the list for Xmas!
A full face helmet and set of gloves will save many tears and be a good investment. Fly, Fox, Kali and THH all make good light options with reasonable ventilation.
A set of elbow pads will also be worth the investment once he starts moving a bit faster.
My 7 year old has been wearing a full face helmet since he was 2. He likes it and chooses it over his TLD A1 lid. He was wearing it at a birthday party at a local indoor skate park on Friday night when another kid asked why. His reply - "Its really comfy and I like my teeth". The bike specific full face helmets are comfortable, light and not too hot.

Bicycle stores are really bad when it comes to childrens bikes in Sweden, all of them has three gears front etc. This is 1x10 and comes with 26" wheels:
