Two 20-inch freestyle BMX bikes aimed at kids and pre-teens learning park and street tricks. The Dynacraft Tony Hawk 720 leans on the Tony Hawk license and a lower price; the Mongoose Legion L60 leans on Mongoose's BMX heritage and an alloy upgrade. Here is how they compare.
$160 - $190
Best for: Kids 7 to 11 who want a Tony Hawk graphic and an entry into freestyle without a $400 spend
$280
Best for: Kids 8 to 12 who are committed to BMX and will outride a base-spec freestyle bike inside a year

| Stack (mm) | 455 | 335 |
| Reach (mm) | 345 | 315 |
Both are 20" wheel freestyle BMX frames, but they target different rider sizes. The Tony Hawk 720's longer 455 mm stack and 345 mm reach fit kids 4'2" to 4'10" (22"-26" inseam). The Legion L60 uses a true BMX freestyle geometry with a much lower 335 mm stack and a longer 315 mm reach (20.5" top tube) aimed at intermediate riders 5'0" to 5'6" who want to whip the bars and do flatland tricks. If your kid is under 4'10", the Tony Hawk 720 will actually fit better. Once they hit 5 feet, the Legion L60 is the right call.
If your kid wants a BMX for the Tony Hawk graphics and the occasional ride to the skate park, the Tony Hawk 720 is fine and saves you $120. If your kid is actually grinding rails, riding pump tracks, or jumping daily, the Mongoose Legion L60's 3-piece crank and sealed bottom bracket will keep working long after the Dynacraft's 1-piece crank gives up.
