Review: Great bike for beginners - My son is very happy with his new bmx bike. He has used it many times at the skatepark and it seems very safe and durable. My only complaint is that we paid for assembly and the company that did the assembly charged us extra. desertcart needs to fix this automatic assembly feature to be the correct price.

## 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
