The impulse to solve this problem by adding extra wheels predates training wheels. “No sooner was a practicable bicycle made than attention was turned to the three-wheeler as being the safer of the two machines,” Sharpe noted. In the 1880s, there were tricycles that look like today’s bicycles—except instead of a having a single back wheel, they have a pair of wheels, evenly spaced. The problem, as the early innovators learned, was that the extra wheel made matters worse. Any kid who’s tried to corner on a tricycle or training wheels knows this.
To learn to bike, you must solve two problems: the pedaling problem and the balance problem. Training wheels only solve the pedaling problem—that is, the easy one. Learning to balance on a bike is much more difficult, and a “training” tool that eliminates the need to balance is worse than beside the point. Training wheels only train you to ride a bike with training wheels. It’s no wonder your first experience riding a bike with no training wheels was terrifying! You’d never done anything like it before.
In his classic Bicycling Science, the MIT engineering professor David Gordon Wilson dismissed the whole concept of training wheels in a single memorable sentence: “It’s hard to see how training wheels can inculcate any of the desired balancing habits, unless they are off the ground.” Instead, Wilson proposed, try “the commonsense idea of having those learning to ride a bicycle adjust the bicycle’s seat low enough to plant their feet on the ground and practice by coasting down gentle, grassy slopes.”
Wilson’s advice wasn’t new. A century before, young bicyclists were being told the same thing: “Another plan that may be adopted with advantage, is to remove the pedals and place the saddle so low that the feet can easily reach the ground, and then push the machine along in the way the old hobby-horse was propelled, taking care to begin on a level surface.” Do this and you have made a balance bike. But you have also made the first proto-bicycle: the Draisine.
In the beginning, there was Mount Tambora. (Stay with me.) When the Indonesian volcano exploded in April 1816, it blew ash into the outer atmosphere, altering the weather worldwide for months. Harvests failed across Europe; 1816 would be known as the Year Without a Summer. As the price of oats for horses soared, the mind of a young German baron named Karl Drais turned to the idea of a mechanical horse.
His Draisine was a wooden contraption with no pedals or chain. Instead, the rider would walk along the ground and push himself forward, moving faster than a pedestrian could. The invention swiftly spread across Europe and the Atlantic, inspiring numerous knock-offs. But the novelty wore off within a couple of years: The roads were too rough; the ride was exhausting; there were accidents. The bicycle historian David Herlihy has written that early riders of the Draisine soon discovered that “every journey cost a pair of boots.” Drais died in poverty.
To a remarkable degree, the modern balance bike is a copy of the Draisine. Both are made mostly of wood (although not all balance bikes are). Draisine riders leaned forward against a board, not unlike the way children do today, pushed off the ground and sped away. Today, it is easy to see a bicycle in a balance bike. In 1816, no one could: The bicycle wouldn’t achieve anything close to its modern form for decades. Children who hop off a balance bike and onto a bicycle are taking a half-century shortcut.
There are more and more parents who are taking that shortcut. The San Francisco Bicycle Coalition runs a popular event that’s explicitly about junking the training wheels. (They also have a good handout about how to do so.) Balance bike models are proliferating and, according to bicycle dealers, sales are rising.
And they should. Children learning to ride on a balance bike solve the balancing problem first. And they solve it easily: Kids on balance bikes are faster and steadier than the contraptions would seem to permit. (Yield the sidewalk.) They have the same confidence as a child on training wheels, but the confidence is justified: They actually do know how to balance themselves on a bicycle. Once on a real bicycle, these kids only have to learn how to make the pedals work. Learning to pedal while balancing is still tricky, of course, but it is far simpler than learning to balance while pedaling.
So skip the training wheels and get rid of the pedals instead. The longstanding popularity of training wheels is a historical headache; no one knows why anyone ever thought they’d be good at what they’re meant to do. Instead, they are a paradigmatic case of a learning tool that teaches the wrong lesson. Once they disappear, only the makers of Band-Aids will feel the pain.
