My sons hands can clasp it safely and the screw on the side doesnt do** A: There is a reach adjustment screw which is a small phillips screw. That'll move that lever closer and further away from the handelbar. Thanks. **Q: It says this typically ships within 1 to 2 months. How soon should I expect this item to actually ship and will it really take up to 2 months?** A: I ordered when it was in stock showed up within 3 days. It could take the whole 2 months, as shipping sucks lately and also the 18" bike has been backordered in multiple brands for a while now. **Q: Can u put a bigger seat on it so it’s easier to sit and pedal?** A: I would say so. It’s a skinny seat for tricks my grandson said. He’s 9. Lol **Q: Why did my bike come with no pedals** A: Hi. We're sorry to hear that. Within the product's one-year limited warranty, we'd be happy to provide replacements for pedals that were missing. We ask you to please reach out to us at 800-626-2811, Monday-Friday 7 am-6 pm CST.
