Our take on the Razor MX400 Rocket Dirt Bike Black 24V 2 Pack

The Razor MX400 Rocket is a 24V electric dirt bike with a 350W chain-driven motor, a twist throttle and a hand-operated rear brake. It runs about 30 minutes per charge and tops out around 14 mph, so it is a step up from Razor's smaller MX350 but still a toy-grade machine, not a youth motocross bike. It suits riders 13 and up who want off-road-style fun on dirt, grass or gravel. Owners like the low running cost and simple setup; the long charge time and plastic build are the usual complaints.

What reviewers say

Owners treat the MX400 as a fun, affordable first electric dirt bike for kids and teens. They praise the torque and the real-bike feel, and most criticism centers on battery life, charge time and fragile plastic parts.

What people mention
  • Battery lifeCriticisedRiders say a full charge lasts only about half an hour, and the 12-hour recharge limits back-to-back sessions.
  • PowerPraisedOwners report quick acceleration and enough torque to climb mild hills and grass.
  • Build qualityMixedThe steel frame holds up, but plastic body panels and fenders crack in minor spills.
  • AssemblyPraisedBuyers describe setup as quick and straightforward with basic tools.
  • NoisePraisedIt runs quietly, so it can be used around the yard without disturbing neighbors.

Questions and answers

Is the Razor MX400 good for a 13-year-old?
Yes. Razor rates it for ages 13 and up with a 140 lb limit, and the 24V motor is mild enough for a first powered bike under supervision.
How fast does the MX400 go?
Top speed is around 14 mph. It is meant for dirt, grass and gravel, not public roads.
How long does the battery last per charge?
About 30 minutes of continuous riding. Charge time is roughly 12 hours, so plan one session a day.
Does it come with a charger?
Yes, a wall charger is included. The battery is sealed lead-acid and is not swappable mid-ride.
MX400 vs MX350: which should I get?
The MX400 has a bigger 350W motor, more speed and a higher weight limit. Choose the MX350 only for smaller, lighter riders.
Can adults ride it?
Only small adults. The 140 lb limit and compact frame rule out most grown riders.
Where is the Razor MX400 Rocket Dirt Bike Black 24V 2 Pack cheapest?
