Kids Bikes - Teaching Them To Ride - Advice Needed

[19wisconsin64]

Hi, so ......my baby girl is now going to be 5. She's tall, funny, and has the attention span of a squirrel during acorn season. Bought her a good bike that fits her, and will put her in a helmet, strap some gloves onto her tiny hands, and maybe encase her in a football (American) outfit for padding. ​

Actually, got a great deal on Costco for $280, overnight shipped, and no tax. A lot of a kid's bike, but it sure is swell, and a lot less expensive than the last pair of cycling shoes her Daddy bought.

Are there any good videos on YouTube, or words of wisdom before I put her on the bike and pray she doesn't run into pedestrians, small dogs, or motor vehicles? The brakes are hand brakes, the bars are upright, but still....should I wait another year to teach her, or just take her to a grassy hill in her padded outfit and hope for the best?

Would like her to enjoy cycling, but want to ease her safely into it. We've watched a lot of women's cyclocross races in person, we've watched a lot of women's racing online, now it's time for her to spin those 4" cranks and be free!

Any advice, jokes (good or bad) will be greatly appreciated! Thanks
