## Questions & Answers

**Q: Is there a way to adjust the distance of the handbrake lever to the handle bar? 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. We are also available via DM on Facebook, Instagram, and Twitter. Please have your bike’s model number and date code handy. These can be found on a black and silver sticker on the frame above the pedal area. Warm Regards
