Redline MX-Expert XL Y-20 BMX Bike (Gloss Black) (20" Toptube)
I bought this bike for my 10 year old and it’s perfect. He is new to bmx racing and a heavy set @130 pounds and didn’t want to deal with replacing wheels and parts from hard use. Great starter bike and competitive for the price. I still a ride a mx24 from 2016 and is still just a great solid bike!! Dans comp is also an amazing company to work with!
